The developer posted 4–5 essay tips per day on TikTok and Instagram from fictional AI-generated student accounts, urging people to search the App Store. The app's name happened to claim search terms like 'redação enem,' 'corretor' and 'nota mil.' [Mobile App](https://stringers.io/en/apps/index.md) · iOS · written 11-6 Redação ENEM: Corretor NotaMil · Augusto Nicolau Gobatto # A fictional female student posting 4 essay-writing tips a day: a solo-built AI essay-correction app blew up the week before Brazil's college entrance exams **What it is** An iOS app for Brazil's ENEM college-entrance exam takers: snap a photo of your handwritten essay, and AI grades it 0–1000 against the official five-criteria rubric with feedback on each. One essay a day is free, and R$14.90 buys a pass that lasts until exam day. **Why it took off** It rode the last week before the Nov 8 ENEM essay exam. Developers used AI-generated fictional student accounts to post 4–5 essay tips a day on TikTok and Instagram, telling people to search the App Store, and the app's name happens to occupy search terms like "redação enem / corretor / nota mil." **C** **How to play it:** skip ENEM. Pick an essay exam with a fixed date and an official scoring rubric, where AI grading hasn't been swamped by free tools yet. Launch 2–3 months before the exam, sell a one-time pass that lasts until exam day, and use AI-generated student personas to post daily tips that send people to search the store. Grade C: The playbook is clear and the cost is tiny, so you could copy it for another exam. But this one is small, revenue is unverified, the ENEM essay-grading space is already packed with free tools, and demand only spikes for a few weeks before the exam, so copying it isn't worth much.

Apple doesn't publish download counts; rating growth is a proxy for downloads. "Redação ENEM: Corretor NotaMil" is an indie-dev iOS app from Brazil: snap a photo of a handwritten essay and get it scored against the five official ENEM competencies within a minute. In Nov 8, when the ENEM essay exam ran, it climbed from #99 to #45 on the Brazil Education Top Free chart in the final week before the exam. Behind the push is a fictional student persona, "Mika", generated with AI, who posts on a schedule on TikTok and Instagram, with every post ending in the same line: "search it on the App Store". It's small and the niche is crowded, so this specific app isn't worth chasing. But its playbook (exam-season pass + AI persona content + store search terms) can be lifted and reused for any other exam. ### Nov 5, four on-time posts Nov 5, only three days until the ENEM essay exam. TikTok account @vaiestudamika (nickname Mika)13:01 posted: "não façam isso: falar com alguém na sala elimina de verdade" — don't do this, talking to someone in the exam room will really get you disqualified.14:15 Another post: "ENEM 2026 possible essay topic: challenges of solid waste management in Brazil", with ready-to-memorize "universal opening sentences" listed below it.15:30 One covers "how to handle a topic you've never seen", 16:45 one covers "nobody can finish reviewing everything before the 8 date, and that's fine". Four posts, all timed to the minute, with views of 206, 251, 1, 0 (TikTok, 11-06). Every one except the prediction post ends with the same parenthetical: > (I fix my own essays on NotaMil, a free app, search for it in the App Store) —— my essays are all corrected on NotaMil. It's a free app, search for it in the App Store. Mika isn't a real person. She has 98 videos and 7 followers on TikTok. The same-named account on Instagram has 128 posts and 47 followers, and the posts are labeled "AI content" by the platform. The earliest one we could find is from Oct 8 (checked 11-06). The app maker is Augusto Nicolau Gobatto, and this is the only app under his name. He also sells a course on Hotmart (Brazil's biggest online course platform) called "Reels com Mascote": > Post reels every week with no face, no filming, no editing. Claude writes the script, a mascot voices it, lip-syncs it, and adds captions, so the videos are ready to post. Each reel costs roughly R$1 to produce. So Mika is very likely the live case study for his course (my inference): the AI tag, the fixed posting schedule, and the same formulaic ending all line up. ### What it is Store page's first line: "Você escreve, fotografa, e em menos de um minuto sabe sua nota" — you write, you snap a photo, and within a minute you know your grade. ENEM essay max score of 1000, made up of five competencies worth 200 points each: grammar, topic and text type, argument organization, cohesion, and the "social intervention proposal." NotaMil scores each of the five and writes a comment for each, quoting your own sentences to show what works and what to fix. It also checks for automatic zeros (too few lines, or not written as an argumentative essay). Its two latest updates added "Give me a topic" (a bank of 2009–2025 past exam prompts plus 2026 predicted topics) and "Swap out your connectives" (App Store update notes, 11-02). The paywall is blunt: the free version lets you revise 1 essays a day, and the store page sells it as "one essay a day is the difference between passing and almost passing." For unlimited revisions you buy the "Passe ENEM 2026" one-time purchase for R$14.90 (about $2.7), good until exam day, not a subscription. In the final week before the exam, the app shows a "Reta final" (final stretch) discount banner. ### How much it grew: a small chart climb | Date | Brazil Education Free Chart | Total ratings | |---|---|---| | 10-28 | 114 | 27 | | 10-30 | 97 | 30 | | 11-01 | 105 | 38 | | 11-03 | 99 | 45 | | 11-04 | 74 | 46 | | 11-05 | 49 | 48 | | 11-06 | 45 | 53 | Launched Sep 4, Brazil store only. As of 11-06, the App Store shows 56 ratings at 4.36 stars. It has never charted on the overall or Top Grossing lists. Here's the scale: #45 on the Brazil Education Top Free chart is a low bar, and three or five new ratings a day can push it up. Downloads and revenue aren't public, and since it never reached Top Grossing, revenue is probably small (estimate). The few reviews are short, like "Corrigiu certinho" (corrected it perfectly) and "not just a rating, it also points out what to fix." ### Why this week ENEM is Brazil's college entrance exam. 2026 saw 5.05M sign-ups (Agência Brasil), with two Sunday sittings on Nov 8 and 15, and the essay on day one. From 11-03 to 11-06 its rank climbed from #99 to #45, right at the peak of the final-week essay practice before the exam. That also means the demand has a hard deadline: once the Nov 8 afternoon essay is submitted, this app is useless to this year's test-takers, and Passe also ends on exam day. ### Where users come from Break it down, and it's three things stacked together: - **Batch-posting tips from an AI persona they built themselves. The content is stuff exam takers bookmark: predicted questions, template phrases, the five elements of an intervention plan, exam discipline, how to split your time. Single posts get anywhere from 0 to a few hundred views, with almost no followers; but TikTok and Reels push content to non-followers by default, so the volume comes from posting four or five times a day, about a dollar per post.** - **No link, just tell people to search the store.** Every ad says "search the App Store." The app name "Redação ENEM: Corretor NotaMil" with the subtitle "Nota na hora, 5 competências" (instant score, 5 competencies) lands squarely on redação enem, corretor, and nota mil. "Redação nota mil" (perfect-score essay) is already a huge topic in Brazilian student circles, and #redacaonotamil has 1.9M views on TikTok, 10-31. The brand name is riding a search term that already exists (inferred, most likely). - **Timing.** Covered above. No trace of it buying ads, hiring influencers, or getting press, and nobody is talking about it on X. Can't confirm whether it runs Apple Search Ads. ### Who it's competing with AI essay graders for ENEM are already standard in Brazil, and most of them are free: | Competitors | What it is | vs NotaMil | |---|---|---| | coRedação / respostaCerta | Web + App, the App has 1,054 ratings | Free and instant, recommended by Guia do Estudante | | Glau | Web + app, 190k-question bank + unlimited grading | Find creators to promote it, 420k views per video | | Educt Redação | iOS + Android, 43 ratings, 4.9 stars | Same features, photo to score in one minute | | Redação ENEM - Agora Passei | iOS, listed 2026-08 | Solo devs in the same period, 6 graded | | Brasil Escola Corrige Aqui | UOL portal web tools | Free, paid version lets you snap photos | | Folha's ENEM essay AI | Built by a major newspaper itself, free | Can still revise Fuvest essays from September | | Descomplica | Large online course platform | Paid courses include 30 AI essay grades per month | | ChatGPT / Gemini | General-purpose models | ENEM creators keep teaching people how to score essays with them | NotaMil's own differences: native iOS, built around handwritten essays, checks zero-score rules, one-time payment per exam season, updated weekly. Most of these are small improvements, and competitors have them too. It breaks through because of timing, content distribution, and store search terms, not because of the product itself. ### If it were you **Bottom line:** Don't copy this one. Brazil's ENEM essay grading is already crowded with free tools, and this year's window closes in Nov 8. Next year you'd have to fight your way in again from scratch. The three things worth taking are the ones you can reuse for any exam: a one-time pass sold by exam season, an AI-generated account posing as a fellow test-taker, and driving downloads through store searches for a specific keyword. **Who it's for:** Solo developers, 1–2 of them, who know an exam with fixed dates, official scoring rubrics, and handwritten essays, where AI essay grading isn't yet dominated by free tools. Someone who can batch-produce short videos with AI and doesn't mind posting four or five a day. **Who it's not for:** Anyone aiming at the main battlegrounds already filled by big platforms and free tools, like ENEM, IELTS, or TOEFL writing. Anyone counting on subscriptions for long-term income (test-takers leave once they're done, and a new batch arrives every year). Anyone hoping the product alone will set them apart, since the underlying grading capability is available to everyone, and general AI models can score essays on their own. **How to do it:** Pick one exam and launch 2–3 months before it. The core features are three steps: snap a photo, score against the official rubric, and comment on each point by quoting the original sentence. Add zero-score rules, past exam papers, and a predicted-questions bank. The free tier gives one essay a day. Paid is a pass that lasts until exam day, priced around the cost of a meal. In the final week, run a discount banner and push the predicted questions. **How to get users:** Create a fictional fellow-test-taker account, no face, and label the AI clearly. Post 4–5 tips per day that test-takers want to save, and end each one with a line like "I fix my essays on XX, search for it on the App Store." Put the exam's most-searched terms in the app name and subtitle. Post on TikTok and Reels at the same time, watch which content types (predicted questions, stock phrases, exam-day discipline) get the most views, and post more of those. **When to start:** Work backward from the exam date. Launch 3 months before the exam and start daily posting 6 weeks out. If you start with less than a month to go, there's basically no time. **Signs you've misread it:** ① NotaMil's review growth stalls after Nov 8, and it doesn't pick back up before 15 or during next year's Fuvest and Unicamp seasons. That would mean this approach only works for a week's tail, which can't support a year of revenue for a product. ② Accounts like Mika keep posting daily, but views stay in the hundreds and App rankings stop moving. That would mean this spike came from natural search right before the exam, not from the content. ③ Platforms start mass-throttling persona accounts that are labeled as AI. Then the cheapest acquisition path gets much narrower.

Posts scheduled daily at 13:01/14:15/15:30/16:45. Each post ends with "eu corrijo as minhas no NotaMil, app grátis, procura na App Store". Single-post views 0–900. - **Verified** **A low-cost method for developers to auto-produce videos** : Augusto Nicolau Gobatto sells a "Reels com Mascote" course on Hotmart plus a Claude skill, claiming each reel costs about R$1. - Inferred **Store search / ASO** : The content says "search on the App Store" but includes no link. The app name claims Redação ENEM / Corretor / NotaMil, and it piggybacks on the #redacaonotamil hashtag. - **Verified** **Exam season (platform event)** : ENEM 11-08/11-15, with 5.05M registrations. Rank rose from 99 to 45 in the week before the exam. The app runs a "Reta final" discount. - Inferred **Seeding under other accounts' posts** : Jina summaries show the same wording on posts from Uniexpo and proflorenaleon, but no matching visible comments were found. - Inferred **Paid ads / creators / media / X** : None found (x-radar: 0 posts; the ad library only tracks products on its list). ## Redação ENEM: Corretor NotaMil (iOS 6806009425) research report Date: 2026-11-06. Developer Augusto Nicolau Gobatto (individual; this is the only app under his name). Launched 2026-09-04, Brazil only, free with one-time in-app purchase. ### Bottom line This is a small individual app for ENEM exam season. It gained traction mainly from two things. First, timing: ENEM 2026 essays are on Nov 8, and the last week before the exam is peak demand for essay practice. Second, the developer's own batch-produced AI content. Using a fictional student named "Mika," he automatically posts 4–5 ENEM essay tips a day on TikTok and Instagram. Each one ends with "I fix my essays on NotaMil, free app, search the App Store," pushing people to store search. In the store, the app name happens to hold keywords like "Redação ENEM / Corretor." The product's differentiators (handwritten input, one-time payment per exam season, fast iteration) are real, but they aren't the main reason it took off. Its scale is also small: 56 ratings, #45 in Brazil's Education Top Free chart, not on the grossing chart. Calling it a "breakout" overstates it. A more accurate description is that it surfaced for a week before the exam on a low-barrier, small chart. ### 1. Data (our appstore library, Apple API) | Date | Brazil Education Top Free rank | Total ratings | Version | |---|---|---|---| | 10-28 | 114 | 27 | 1.0.8 | | 10-30 | 97 | 30 | 1.0.9 | | 11-01 | 105 | 38 | 1.0.9 | | 11-03 | 99 | 45 | 1.0.9 | | 11-04 | 74 | 46 | 1.0.10 | | 11-05 | 49 | 48 | 1.0.10 | | 11-06 | 45 | 53 | 1.0.10 | - Source: appstore library app_day / chart_rank. It only charted on Brazil's Education Top Free (genre 6017). It never made the overall or grossing charts. - Apple lookup (Brazil store, 11-06): rating 4.36, 56 ratings in total, current version 1.0.10 (released 11-02). - AppInsider: 10-17 first saw it when it ranked #89 on Brazil's Education Top Free chart; 10-29 it reached the top 100; its calculated average weekly new ratings were 14. It was updated 4 times in 30 days (https://appinsider.io/app/redacao-enem-corretor-notamil-6806009425). - Revenue: The only in-app purchase is "Passe ENEM 2026" at R$14.90. It's a one-time payment, not a subscription, valid until exam day, and includes unlimited grading and a "rewrite workshop." The free tier allows 1–2 essays per day (the store description says 1, and the 1.0.4 release notes say 2). Source: Brazil App Store page. - Earnings: Not on the grossing chart, so revenue is likely very small. We have not verified it. ### 2. Why now: timing - ENEM 2026 exam dates are Nov 8 and 15, with the essay on day one. Registrations: 5,051,345 (Gazeta do Povo, Agência Brasil, Brasil Escola). - Its rank climbed from #99 to #45 between 11-03 and 11-06, exactly in the last week before the exam. The developer also matched that rhythm: the app has a "Reta final" discount banner; 10-28 added "give me a topic," and the question bank holds past exam questions from 2009–2025 years plus 2026 years of predicted questions; 11-02 added linking-word replacement suggestions. - This demand is strongly seasonal. After the essay on Nov 8, demand basically disappears, and the Passe expires on exam day too. ### 3. Growth tactics (broken down) 1. **Self-made AI student persona, posting at scale (confirmed)** - TikTok account @vaiestudamika (display name Mika). Bio reads "Pesquise nota mil na Apple Store e corrija sua redação de graça." 98 posts, only 7 followers, 1,656 total likes (TikHub, 11-06). Recent posts go up daily around 13:01, 14:15, 15:30, and 16:45. Single-post views range from 0 to 900, and the latest 9 posts total about 900 views. Every caption ends with the same line: "(eu corrijo as minhas no NotaMil, app grátis, procura na App Store)." - There is also a same-named @vaiestudamika on Instagram: 128 posts, 47 followers. The platform labeled the posts "AI content." The earliest Reel found is from Oct 8 (Jina search results; example Reel links instagram.com/reel/DfN6sKACTca/ and DfTETjEDEAS/). - The content follows a classic pattern of "useful tip cards with soft product placement": likely essay topics, stock phrases, the five elements of an intervention plan for C5, exam-day discipline, and how to pace your time. - The developer sells a course on Hotmart called "Reels com Mascote: mini curso + skill". The course pitch: no face on camera, no filming, no editing. A Claude skill writes the script, a pixel-art mascot voices it and lip-syncs, and subtitles are added. "Each reel costs roughly R$1 to produce." The course sits in the "Push Club" members area. He has been a Hotmart seller for 8 years (https://hotmart.com/pt-br/marketplace/produtos/reels-com-mascote-mini-curso-skill/M108286760B). So Mika's account is most likely running on this low-cost auto-video method. The AI label and the fixed posting schedule also fit. - The account has very few followers, but production costs are tiny and it posts a lot. Instagram Reels and TikTok both push content to non-followers, so follower count says nothing about reach. Whether he uses IG Trial Reels is unverified. 2. **Store search / ASO (inferred, likely)** : the content says "search for it on the App Store" instead of linking, so downloads come through store search. The app name "Redação ENEM: Corretor NotaMil" with subtitle "Nota na hora, 5 competências" covers the high-volume terms redação enem, corretor, and nota mil. Also, "redação nota mil" is already a big topic on TikTok and Instagram (#redacaonotamil has videos with millions of views, e.g. @gabzzmacedo's 10-31 clip at 1.9M views), and the brand name rides that existing search term. 3. **Seeding in other people's posts (unconfirmed)** : in the Jina search snippets, the same line "eu: (agora corrijo uma por dia no NotaMil...)" shows up on post pages from other accounts such as Uniexpo and proflorenaleon. Opening those pages, I did not find it in the visible comments. It is more likely Mika's content pulled in from the page's "more posts / related Reels" section. So I cannot conclude he is commenting under big accounts. 4. **No paid ads, creator deals, press coverage, or X activity found** . x-radar searches for NotaMil and gobatto returned 0 posts over the last 60–90 days; there is no press coverage. Our ad library only tracks products on our list, so a miss doesn't mean no spend. Whether he runs Apple Search Ads is unknown. ### 4. Competitors The space is crowded. AI essay correction for ENEM is standard now, across websites, apps, and built-in features from big companies: - **coRedação** (website coredacao.com; the same company also has the app "respostaCerta", listed in 2025-01, 1,054 ratings, currently #188 on Brazil's Education Top Grossing chart): free, instant, graded to ENEM standards. Guia do Estudante lists it among "free essay correction sites". - **Glau** (web + app, glau.com.vc): AI correction, "results in 3 seconds, unlimited", plus a 190k-question bank and mock exams. Since 2024 it has been promoted by creators on TikTok, with a single video at 420k views (@bykemyst). - **Educt Redação** (iOS/Android, listed in 2025-08, 43 ratings, rated 4.9): same pitch, "snap a photo, get 0–1000 and five competency scores in 1 minutes", nearly identical to NotaMil. Also uses TikTok creators (@leticia_estuda, one video at 10k views in 10-19). - **Redação ENEM - Agora Passei** (iOS, listed in 2026-08-20, 6 ratings): an indie developer and a direct rival from the same period. The App Store "customers also bought" section pairs it with NotaMil. - **Redação Nota 1000** (web + Android): human teacher corrections, paid, operating for several years. - **Brasil Escola "Corrige Aqui"** (web, part of UOL): free, with a paid tier that adds photo upload and unlimited use. - **Folha's ENEM essay AI** (web, free, also grades Fuvest essays from 2026-09): built by a major media company. - **Descomplica** (large online course platform, 3,979 ratings on iOS): paid courses include 30 AI corrections per month. Toda Matéria's Lume, CRIA, RedaIA, and Quero Bolsa are also free or nearly free. - A group of small AI correction services also posts on TikTok: Estuddo, RedaPlay, @corrigeredacaoai, and others. There is also a TikTok account called @notamil26 (an "ENEM diagnostic" web page built on lovable.app, posting since 2026-06, 70 followers). It has nothing to do with this app, but the name collides. - Big-company features: ChatGPT and Gemini grading essays directly is a workflow many ENEM creators teach. ### 5. Differentiation, and whether it's why it took off - What it does differently from competitors: 1. It is native iOS only, and its main pitch is photographing handwritten drafts, which matches the real situation of handwriting essays in exams. Educt, Glau, and Corrige Aqui also accept photos, though. 2. It charges one-time per exam season. "Passe ENEM 2026" costs R$14.90 and lasts until exam day, not a subscription. Students know the deadline, so a one-time fee fits how they think. This is less common. 3. It also checks the zero-score rules (too few words, off-topic, not argumentative prose). 4. It updates weekly, with release notes saying changes are made "based on what students using it every day ask for". 5. The free tier is capped at "1 essays per day", framed around a one-essay-a-day practice habit. - None of these differences are fundamental. Most similar products have them. It broke out mainly on exam-season timing, automated content distribution, and store keywords. Product differences at most explain the good ratings (4.4) and the low paywall. ### 6. How many people know about it - Revenue is not public. There is no TrustMRR listing, and the developer has not posted numbers. There is no X discussion and no press coverage. - The app itself is barely known. But the developer openly sells his "AI mascot auto-video" method, so this playbook may already be circulating in Brazil's Hotmart circles. ### 7. What to take from it - How to build for exam season: launch 2–3 months before a fixed exam date that millions sit; sell a one-time pass that runs until exam day; add a discount banner in the last week before the exam, plus practice question packs and question generators. - How to build the content: invent a fictional student of the same age (no face, AI-generated, labeled as AI on the platform). Post 4–5 practical short videos a day on a schedule, at about R$1 per video. Don't link anywhere.
