# A tech YouTuber built a plugin for his viewers: 4 videos, 5,000 Koreans using free Gemini to write Naver blog posts

**What it is** A Chrome side-panel plugin that uses the free Gemini/ChatGPT you're already logged into in your browser to write blog posts and images, then fills them in with one click into the editors for Naver Blog, Tistory, Instagram and Threads. You hit publish yourself.

**Why it took off** The author is a YouTube channel owner whose viewers trust him not to scam them. From late August to late September he posted 4 videos, repeatedly saying "API costs 0 won, not a paid course, no Python needed". That hit middle-aged Korean bloggers who had been burned by paid blog-automation courses. Comment giveaways of keys also pushed the videos into recommendations.

**C** **How you could follow** If you have an audience of your own, take the idea of "borrowing the AI web pages users are already logged into, and filling text into local platform editors" and apply it to Japanese note/Ameba, Chinese WeChat Official Accounts/Xiaohongshu, or WordPress. Publish through your own channel, give away keys in comments, make a video for each version, and monetize through ads and channel memberships.

C grade: growth came almost entirely from the author's own channel and trust, which followers can't copy. The code bar is low and there are already same-name copies. Users stalled at 5,000, revenue is thin, and it depends on the AI web interfaces staying unchanged. What's worth learning is the creator-built tool, distributed through the creator's channel. Chatter in small circles

5,000 users · rating 5.0 (85)

"Ttalkkak SNS" (English name Easy-peasy SNS) is a free Chrome side-panel plugin. It uses the Gemini or ChatGPT web page you're already logged into to write blog posts and images, then fills the results into the editors for Naver Blog, Tistory, Instagram and Threads. The author is a Korean "value-for-money tech" channel owner with 46k subscribers. Plugin users grew from 532 to 5,000, with each jump landing right after a new video he posted. In October he stopped making videos, and user growth stopped with them. What's worth studying isn't the plugin itself, but the approach: a channel owner builds the tool himself and distributes it through his own videos.

### "A blog I couldn't make work even after trying hard in the second half of my life"

On Aug 27, 2026, the YouTube channel 「가성비 덕후 만두얏」 (Value-for-Money Nerd Mandoo) posted a video titled 《AI API 비용 0원!100% 무료 AI로 네이버 블로그 글 작성부터 맞춤 이미지 생성까지 한 번에!》, which translates to: "AI API costs 0 won! Write Naver blog posts and generate custom images in one go with 100% free AI." The first line of the description is the store link. The second paragraph reads: "Just log in to a free Gemini or ChatGPT account. No API key, no cost. A few button clicks produce a blog draft and images, and the tags get filled in automatically."

The channel usually reviews 600k-won laptops, power banks, and wireless fans, and each video typically gets 1,000 to 5,000 views. By Nov 6 this one had 31,673 views and 761 comments, dozens of times the channel's usual comment count (YouTube, 11-06).

The comments read like a class for middle-aged bloggers:

> "I was finally met by a savior teacher, after trying so hard in my later life and still failing at blog writing" (8-30)

> "For a beginner of an older age, you are like heaven." (8-31)

> "You're giving away your skills for free, so I'll watch the ads every single day~" (8-30)

### What it is

After installing, a sidebar appears on the right of the browser. You enter a topic, or drop in a dozen or so of your own photos with a few notes. It goes into the Gemini / ChatGPT / Claude page you're already logged into, asks for you, brings back the text and images, formats them to Naver blog style, and fills them into the editor with one click. For Instagram it generates 1–10 card-news slides and captions with hashtags; for Threads it splits the text into a thread of 500-character posts. The final "publish" button is left for you to click; it never touches your account password (Korean store page; 9-08 and 9-30 video descriptions).

The money setup is light: watch one sponsored ad and get 1 hours of unlimited use, join the channel membership and Pro is unlimited, and you can enter a license key. No website, no pricing page, and the creator doesn't have to wire up any payment himself. YouTube collects the membership fees. Commenters show people really paying: "멤버쉽 가입했습니다" (joined the membership, 10-01), "오늘 2단계 가입했습니다" (joined tier 10-14 today). Member count and ad revenue aren't visible from outside.

### How the 5,000 users came in

| Timeline | User count (third-party tracking curve) | Videos the author posted in the same period (views, 11-06) |
|---|---|---|
| 8-27 | —— | Clip 1: Free AI to write Naver blog posts, 31,673 |
| 9-01 | 532 |  |
| 9-08 |  | Clip 2: Adds Instagram / Threads / Blogger, "no expensive API key needed", 47,588 |
| 9-15 |  | Clip 3: Write from photos alone, 10,438; the intro says "over 1,000 users" |
| 9-21 | 2,000 |  |
| 9-30 |  | Clip 4: 2.0 edition, adds Tistory, "the ultimate free Naver blog automation", 39,658 |
| 10-05 | 4,000 |  |
| 10-16 | 5,000 | No new 딸깍 videos since then |
| 11-01 ~ 11-05 | 5,000 (Chrome Web Store, 85 ratings, 5.0 stars) |  |

The four videos total about 130k views, and each user jump came right after a video. The channel October moved on to tablets, batteries, and laptops, and the extension's user count stalled for a month from mid-October.

Several levers:

**Giveaway in the comments.** The first video promised "leave a comment about your experience and we'll give 10 people a lifetime unlimited key." In the pinned comment, the creator later said "we've given away licenses to 283 people in total" — almost everyone who left a thoughtful comment got one. That's how the 761 comments came in, and the flood of comments likely pushed the video into the recommendation feed (inferred). It also explains why all 85 ratings are 5 stars: some came from grateful fans (inferred).

**Every version is a new video.** Viewers asked in the comments of the first video, "Does it work with Instagram? Threads, Cafe, Blogger?" The second video's intro opens with "There were too many requests, so I built another version." Writing restaurant reviews from photos and adding Tistory follow the same pattern: viewers ask, the creator builds it, a video ships, and a new batch of users arrives.

**Tutorials on Naver Blog.** The creator wrote several install and usage tutorials on their own Naver blog, blog.naver.com/mandooyat, which people find by searching "블로그 자동화" (blog automation) within Naver.

No ads, nobody on X talked about it, no media coverage, and outside the Korean-speaking world almost nobody knows it exists.

### Why this audience and this message

Korean Naver blog operators (small shop owners, one-person marketers, middle-aged people hoping to earn from blog experience programs and product reviews) have long been surrounded by paid blog automation tools and courses: you buy a course, set up Python, and pay OpenAI for API access yourself. The intro of the 2.0 video rejects each of these in turn: "Expensive paid courses? Not needed. (This video is the free course!)" "Expensive AI API costs? Python setup? Not needed at all." The first FAQ answers "Will you secretly charge me later?": "We don't even collect card numbers, so forced charges are impossible."

The comments almost all echo the same sentiment:

> "This guy really teaches it, takes no money, and runs no ads." — 9-30

> "Wow, for the first time I'm seeing info that isn't a course sales pitch." — 9-30

"Free" works because of a trick: the AI runs on the user's own free Gemini web quota (the video specifically recommends the free Gemini tier, which has generous image quota), so the creator has almost no inference cost. That lets thin monetization, like watching ads for 1 hours of use, hold up.

The trust was also built over eight years: the channel has 1,500 videos teaching people who aren't very technical how to save money buying computers. This time the channel owner built the tool and presented it personally, so there was no cold start.

### Who it's competing with

| Competitors | Scale (Chrome Web Store) | How it differs |
|---|---|---|
| 늑대플 | 5,000 users | Mainly a Naver blog checker (word count, banned words), with AI writing as an add-on; no Instagram / Threads |
| 로워드 어드바이저 | 4,000 | Keyword analysis + auto-publishing, charged through its own backend |
| 판다랭크 | 30,000 | Keyword and ranking analysis, no article writing |
| Filling tool for 블덱스라이터 and 혁신 블로그 AI | 336–1,000 | Just moves articles from its own SaaS into Naver |
| Wrtn, Gemini in Chrome | Big companies / top players | Writes only, doesn't format to Naver's layout, add images, or fill the editor |
| 나타스 딸깍 | Not shown in the store | Same-name copycat from October: also borrows the user's web session, also offers a "free 1-hour pass," and adds 60 card templates and product promotion |

After September, a few similar extensions appeared, with users ranging from 0 to a few dozen. Functionally, 딸깍 really is the only one with zero API cost and one sidebar covering six common Korean editors, but its user curve lines up exactly with the video timing, which shows it grew because of the channel, not the feature. The same channel's February push "한방 AI" (959 views) and July comparison-shopping extension "쇼핑 거지몰" (587 views) didn't take off. A channel alone isn't enough; you also have to hit a pain point viewers really feel.

### Unmet needs in the comments

Since October, many comments have asked for the next feature:

- "Can it write Naver Shopping Connect product posts?" (asked in 10-03 and 10-26). The copycat 나타스 딸깍 is already doing this.

- "If I post the same article to Google, Naver, and Tistory, won't it get downranked?" (worried about in 10-06 and 10-16).

- "Does it work with WordPress?" "Please also make something for YouTube Shorts."

- "Daily visitors have quietly passed 250." (250) "10-03". Feedback like "it really works" is rare; most comments are just thanks.

### If it were you

**Verdict:** This is something to learn from, but copying it step by step isn't worth it. Its moat isn't the code. Filling the editor through a borrowed web session can be built in a weekend, and October already had a same-name copy. The real moat is a channel with 46k subscribers whose viewers trust it not to scam them. Without that channel, you're left with a plugin with 5,000 users, monetized by ads, that could break at any time when ChatGPT or Gemini update.

**Who it suits:** People who already have an audience of "want to make content but aren't technical" viewers: productivity creators in Chinese, Japanese, or Vietnamese, teachers who run courses, and people who run community groups for small merchants. You only lack the tool, and this write-up gives you a ready-made template.

**Who it doesn't suit:** Indie developers without their own traffic who expect to grow a plugin through Chrome Web Store search. The category isn't short of listings there; what's missing is trust.

**How to build it:** Pick a writing audience that has been burned by "paid course + API key" offers, and pair it with a local platform: note or Ameba in Japan, WeChat Official Accounts, Xiaohongshu, or Zhihu in China, or WordPress. Keep the features to three things: write using the free AI the user is already logged into, format and add images for each platform's layout, and fill the editor while leaving the publish click to the user. Monetize it the same way: ads in exchange for extra time, plus channel memberships, with no payment handling.

**How to acquire users:** Follow its video structure. In the first 13 seconds, demo it ("click once, the whole post appears") before introducing yourself. Put the store link on the first line of the description. Give away lifetime keys in comments, and do it generously. Turn needs viewers raise in comments into the next video.

**When to move:** Before someone in your market does this first. Nothing comparable has appeared yet in Japanese or Chinese markets, but the barrier is low, so whoever publishes first claims the trust. Also, free quotas and interfaces on Gemini and ChatGPT web change constantly, so your window depends on theirs.

**What would prove the read wrong:** If 딸깍 SNS could grow past 10k on its own without new videos, that would mean store search and word of mouth can carry a product without a channel. Conversely, if Google or OpenAI start blocking plugins that borrow web sessions, or if Naver explicitly downranks AI-written posts, this playbook stops working.

## Why 딸깍 SNS (Easy-peasy SNS) took off

> Chrome extension `jgfdeppnjijgddbledcbhgiinddkcjem`, published by shmch21 (shmch21@hotmail.com), first released 2026-05-15, current version 2.0.26 (updated 2026-11-04). Research date 2026-11-06.

### Bottom line

The Korean IT review YouTuber "가성비 덕후 만두얏" (46.6k subscribers) wrote and filmed his own videos to promote a free extension. He posted 4 dedicated videos between 8/27 and 9/30, about 130k views in total. Each video moved the extension's users up a notch (532 → 2k → 4k → 5k). He posted no new videos after October, and the user count stalled at 5k. What won users was the pitch: no API key, no Python, no course to buy. Write Naver blog posts with the free Gemini or ChatGPT web app you're already logged into. The target audience is middle-aged and older newcomers and small business owners on Naver blogs in Korea.

### What it is

- A Chrome side panel extension. It uses the Gemini, ChatGPT, or Claude web sessions you're already logged into in your browser to generate blog text, images, Instagram card news (1–10 slides), and Threads threads (split at 500 characters). Then it fills the content into the editors for Naver Blog/Cafe, Tistory, Blogger, Instagram, and Threads in one click. You hit Publish yourself; it deliberately doesn't post automatically. (Source: Korean store page [chromewebstore.google.com/detail/jgfdeppnjijgddbledcbhgiindd…](https://chromewebstore.google.com/detail/jgfdeppnjijgddbledcbhgiinddkcjem?hl=ko))

- How it's paid for: watch one sponsored ad to unlock 1 hours of free use; join the "만두얏" YouTube channel membership for unlimited Pro; or register a license key. There's no website and no pricing page (same source; chromestore database `paid_signals=['description mentions paid']`).

- Currently 5,000 users, 85 ratings, average 5.0 (chromestore database 2026-11-01/03/05 snapshot).

### Growth data

### Copycats

- **Natas 딸깍 (Natas Click)** (Chrome `nghffljpbloaopddoehnlmpfcfiklaoj`, developer heltiara2 / happygold.shop, updated 1.0.41,2026-10-25): it uses the name 딸깍 directly, calls the Gemini/ChatGPT/Claude you already subscribe to, and likewise offers a "free 1-hour usage coupon" and a licensed key. On top of that it adds 60 card news templates, card Reels videos, and Naver Shopping Connect for product promotion. The store page doesn't show a user count (likely very few).

- After September, a few similar small extensions appeared. Their users number from 0 to a few dozen: a blog AI tool (2026-09-13,29 users), 아이디어팩토리 Creator Factory (2026-09-07,0 users, and its "user-confirmed input" wording matches 딸깍), and BLOG AI HELPER (2026-11-01,0 users, also making card news and filling it into Naver). (chromestore database)

### Where users come from

1. **The creator's own YouTube channel (confirmed, main channel)** : the first line of the description for each of the 4 videos is the store link, and each user jump landed right after a video went up.

2. **Comment giveaway (confirmed)** : the first video promised to give 10 people a lifetime unlimited key for leaving a comment about their experience. That pushed the comments to 761, dozens of times the channel's usual level. The comment section is mostly middle-aged and older Naver blog newcomers ("Those of us who are older and new to this are amazed" and "Hope the ad revenue makes you rich"). Lots of comments help a video get pushed into YouTube's recommendations.

3. **Naver blog advertorials (confirmed)** : the creator's blog blog.naver.com/mandooyat published several installation and usage guides (224405750424, 224413788626, 224428041084), so people searching "블로그 자동화" on Naver can find them.

4. **YouTube community post + JocoHunt (confirmed, small volume)** : 9/29 community post announced Tistory support and asked subscribers to upvote on JocoHunt, the Korean Product Hunt, landing #3 on the AI Tools weekly chart; the JocoHunt page shows only 1 votes, so the traffic it brought is negligible.

5. **Store search** : the page is available in Korean, English, Spanish, and Japanese, and the title is packed with keywords like "Naver·Blogger·Instagram·Threads AI writing." How much this contributes is unverified.

6. Ads, X, Reddit, media: none found (x-radar returns nothing for "딸깍 SNS").

### Why it's working

1. **Distribution is free, and it comes with trust** : 만두얏 has run a "value-for-money tech" channel for 8 years, with 1,548 videos and 46.6k subscribers. The audience already wants to save money and isn't very technical. The creator explains the extension personally, so there's no cold start.

2. **It hit a real pain point and a real distrust in the Naver blogging community** : the Korean "blog automation" market is full of paid programs and course sells, and they require API keys and Python. The video titles repeatedly shout "API ¥0", "not a course sell", and "no Python needed", and the FAQ even answers "will it secretly charge me?"

3. **A technical shortcut makes "free" work** : it runs on the user's own Gemini web session (the videos recommend the free Gemini tier, which has generous image quotas). The creator's inference costs are close to zero, so lightweight monetization like watching ads for 1 hours of use can sustain it.

4. **Iterating on viewer requests, with each iteration as a new video** : it started with Naver blog support only (8/27). Viewers asked "What about Ins? Threads?", so it added Ins, Threads, and Blogger (9/8), writing articles from photos (9/15), and Tistory (9/30). Each major version got one video, and each video brought one user jump.

5. **Careful on compliance** : it insists it never clicks publish for you and never touches account passwords, which avoids being treated by platforms as an auto-posting bot. That also eases worries about Naver downranking.

### Differentiation

- Compared with Korean peers: most are SaaS (own backend, token-based pricing) or analytics tools. 딸깍 is the only one with **zero API cost and a single side panel covering six editors: Naver, Tistory, Blogger, Ins, and Threads** .

- Compared with big companies and Wrtn: those products only handle the "writing" part. 딸깍 also handles Naver-format assembly, images, and filling the editor, which saves copy-paste and layout work.

- But the differentiation is **not the main reason it took off** . The main reason is channel distribution: the user curve lines up with video release dates, and growth stopped when the videos stopped. The feature differences only gave the creator a reason to make another video. The technical barrier is also low, and someone copied the same name and model by October (Natas 딸깍).

### Visibility

Word of mouth in small circles: roughly 130k views on Korean YouTube, plus the creator's own Naver blog. No website, no disclosed revenue, no press coverage, and no one talking about it on X. Outside the Korean-speaking world, almost nobody knows about it.

### What others can borrow

- The pattern of "borrow the user's logged-in LLM web session and fill content into the local platform's editor" could be copied to Japan (Ameba / note / Hatena), China (Xiaohongshu / WeChat Official Accounts / Zhihu), and ecosystems like WordPress.

- The creator builds the tool and distributes through their own channel: the video description links to the store, comment giveaways of lifetime keys drive comment counts, and each major version gets a new video. Monetization stacks ad-watch usage time with channel memberships (YouTube handles membership fees, so the creator doesn't need to run payments).

- It plays the "free, not a course" trust card, aimed at a group that has been burned by paid courses.

### Unknowns

- The user curve before 9/1 (the 5/15 launch through August) wasn't captured, and it's unclear whether the May version had the same product form.

- We can't tell which ad networks back the 1-hour ad-for-reward unlocks, or how many members the channel actually has. No data, so revenue is unknowable.

- All 85 ratings are 5.0. Some may come from the comment-giveaway and fan effect; whether good reviews were solicited is unverified.

- Automating Gemini / ChatGPT through the web session may violate those services' terms, and it breaks whenever the DOM changes. Whether Naver downranks AI-written posts would also affect retention.

- The recall card says the shmch21 account has 6 extensions, but this database only captured one. The channel also promoted "한방 AI" (2026-02,959 views) and "쇼핑 거지몰" (2026-07,587 views), neither of which took off, which suggests a channel alone isn't enough; the topic choice matters too.
