One invite code, one creator: how Cuddli sold AI love stories onto European Top Grossing charts

Cuddli is an AI roleplay app built around cinematic romance stories. On the day of its Nov 5 update, its App Store rating count went up by 43 in a single day, and it appeared on entertainment Top Grossing charts in 17 countries. Looking closer, it isn't really a hit: it's small, and the category is already crowded. The part worth taking is its acquisition method: each mid-tier TikTok creator gets a personal invite code, and both sides receive coins when it's redeemed.

A Spanish-language creator and Hogwarts

In 2026 Oct 16, Mexican TikTok creator leslienatasha (770k followers) posted a video: "T/N makes friends at Hogwarts and is the chosen one." T/N is Spanish-language fandom slang for "tu nombre" (your name), meaning the reader inserts themselves as the protagonist. The video tagged Cuddli AI at the end and displayed a line of text: "Oro: W0bxt9", meaning enter this code to claim coins. The video got roughly 59k views (TikTok, 11-06). Back in Sep 23, she had already used the same code in a Draco Malfoy video, which got 29k views.

That same month, a string of similar videos went up:

• wondercoserr (146k followers) cosplayed Sylus from Love and Deepspace with the caption "SYLUS MY MAN", 98k views;
• velvet.venomx (43k followers) posted a BookTok-style couple skit whose caption opens with "Ad:" and reads "Use our code: NAL6Tr", 41k views;
• lizettemkp (408k followers), estefaniacmar and natiuvv posted Spanish-language videos, caramel.studyy made an English-learning creator version, and ggukiesjeon took the K-pop fan route ("TRY THIS BEFORE IT ENDS").

These creators are all fairly small, but their niches are tightly focused: fan fiction, otome games, BookTok romance novels, and fandom. The official TikTok account has only 4,393 followers, so the traffic comes mostly from these creators.

What it actually is

An AI character chat app wrapped in a visual novel shell. Each character card has an animated video background, characters speak aloud, and as you chat you can "unlock chapters" and branch to different endings. At any point you can generate an image of the current scene. Characters can be official or created and published by users. The most popular user-made character on the website, "Jax", has 58.7k conversations (cuddli.ai).

The store listing says 17+, the interface is English-only, and the app is free to download. It makes money by selling coins: chatting, image generation, voice and unlocks all cost coins.

It's not a new face either. The Android version launched back in 2026 June under the package name ai.layla.chat. It was called "Layla AI: Chat with Characters" and then "Layla AI World: Make your Loop" before the third rename to Cuddli and the "romance RPG story" positioning. It reached iPhone in Aug 5. The iPhone version's developer is listed as a Hong Kong company, LUDO HK LIMITED, but the support email uses the domain of DalaPlay, the Android developer, so it's the same team.

Why it looks like it's growing lately

A cold splash of water first: the numbers are small.

The 5 new ratings in Nov 43 landed the same day as the 1.6.0 release. On Android, ratings jumped by 4 on Nov 159 alone. Before that, France, the UK, Italy and Germany were each adding only 0 to 3 new ratings a day, and on release day they each went up by 6 to 9. Almost all the new ratings are five stars. Inference: the new version added a rating prompt, or they're running a "rate for coins" promotion. It's not that users suddenly flooded in.

Entertainment Top Grossing charts in small European countries have a low bar; selling a modest number of coins is enough to get on them. Monthly revenue is estimated at under tens of thousands of dollars (unverified).

Three things are really driving the growth.

One code, two jobs. The creator's personal code is both a perk for new users (coins on redemption) and a tracking tool for Cuddli: it shows which creator brought how many people and how many payers, with no ad-attribution SDK needed. The official Instagram bio also carries a code. Reviews from the French store show how well this works: in Oct 18, one five-star review's title was simply "Code parrainage 1DT6tx" (referral code 1DT6tx); two other reviews also had nothing but a code as their title ("Ash: kDqnD8", "RwAEZ9"). Users themselves are spreading codes everywhere to get more coins.

Picking the right audience. The fan fiction, otome and BookTok crowd skews female, is already used to paying for romance storylines, and needs like "dating at Hogwarts" or "going on a date with Sylus" are not well served by text-only Character.AI. A US store review from Nov 3 says: "If you like slow-burn romance, this app is great. It doesn't rush things; the relationship builds up little by little."

Users create the content. The official homepage advertises "create characters, join votes, win up to 20,000 coins" and "100 coins for completing verification." The Android store listing also says creators can "build a following and earn from their work." Characters are written and promoted by users, so the company barely spends money producing content itself. On Reddit's r/ChaiAlternatives (a Chai-alternatives discussion board) there are posts like "I found a niche AI chat app and ended up becoming a creator," which read a lot like advertising (inference; the post bodies weren't opened).

No paid acquisition shows up in public ad records, but its top-grossing charts are in Europe while most creators pushing it are Spanish-speaking, and the two don't line up. So it's possible it's buying ads through other channels in Europe (unverified).

Where the money comes from

Selling coins. The first top-up has a discount: $1.49 buys 550 coins, a low entry point. Daily check-ins also hand out a few free coins to build the habit first.

Users' complaints are almost all about coins. UK store, Oct 20: "Lots of story, but the coins could be cheaper. If you spend freely, it gets expensive." Oct 13: "Really wish coins weren't so pricey." US store, Nov 2: "My only complaint is that you can't turn off auto image generation. I only want the story. I usually don't need the pictures, but they still cost coins, and I never asked for them." One French review in Nov 4 went the other way: "Too bad there's no ads you can watch to get coins."

Some people think it's a better deal than similar apps. UK store, Nov 2: "I've tried a few of these AI chat games and deleted most of them, because once the starting coins run out you have to subscribe, and it's too expensive. Cuddli is different: you can subscribe if you want, but it isn't that expensive."

Who it's competing with

This space is already crowded, and most competitors are about two orders of magnitude bigger:

(scale from the App Store and Google Play, 11-06)

"Video background + voiceover + chapters" is already standard by 2026. Cuddler, Viyo, EMOCHI and Linky are all doing it. There's even one on TikTok called "Cuddmi" that also leads with AI romance and otome. The product itself doesn't separate anyone. Distribution does.

If it were you

The call (C): the playbook is worth stealing, the category isn't worth chasing. Cuddli's product is about the same as dozens of rivals, and it's small. What it gets right is the low-cost, self-attributing acquisition setup: "mid-size creators + exclusive coin codes." That setup works in other categories too.

Who it's for: teams that already have an app monetized through virtual currency (stories, companionship, outfits, fortune-telling) and lack a cheap cold-start method. Or teams that know a specific fandom well and speak the local language.

Who it's not for: solo indie devs who want to build yet another AI character chat app head-on. Model and image-generation costs are real, content moderation with 17+ rules can get you flagged at any time, and rivals are buying installs while chasing C.AI-level retention. If you build it, you'll most likely be number 51.

How to do it: don't copy the product, copy the mechanics. Design the in-app currency first: compress the first top-up to $1–2, and give a small daily check-in bonus. Give each partner creator an exclusive code. When someone enters it, both sides get currency. The backend tracks how much paying revenue each creator brings: scale up the good ones, cut the weak ones. If you do AI stories, pick a language or community rivals haven't worked deeply, like the Spanish-language fandom, and grow the characters out of that community's in-jokes instead of building a generic "chat with any character" app.

How to acquire users: find fandom, otome, BookTok and fan-culture creators with 10k to 500k followers. The videos themselves are story clips ("T/N at Hogwarts"), with the code at the end. Add in-app creation contests that pay out currency, so users who write characters promote them and create content for you.

When to move: this playbook doesn't have a deadline and can be used any time. But if what you want to build is AI romance stories, the window is closing. New similar apps launch every month in 2026, and a year from now, hiring fandom creators on TikTok will only cost more.

Signs you've misread it: ① Cuddli's iPhone ratings keep coming in at 20+ a day even on days with no new version and no promotions, and Android installs grow from over 10k a week to over 50k. That would mean the product retains people beyond the codes, and the category has more room than it looks. ② It breaks into the top 30 of entertainment grossing charts in the UK, France and Germany. That would mean small coin purchases can really support meaningful revenue with that audience. ③ The opposite: if creator videos stop over the next month or two and rating growth stops with them, it's running on paid acquisition alone, and when the codes stop, the users stop.

One last line for product builders: the most worth-noting thing about Cuddli isn't "cinematic AI romance." It's one invite code doing three jobs at once: giving new users a small perk, giving creators a reason to promote, and telling you which creator's spend is paying off. That works for any app selling virtual currency.
