Spend 4 diamonds and an underground fight champ chases you: Whispy copied the #1 app, and in 5 months broke into the UK Top Grossing top 15

Whispy AI is an AI romance story app for women. You pick a script from a short-drama trope (an underground fight champ, three hockey roommates, a billionaire sold into a contract marriage) and chat with the male lead to push the story forward, with several diamonds deducted per message. It launched in June 2026, and the gameplay is nearly lifted straight from the category leader Tipsy. Through Meta and Google ads, plus an invite code that pushes users to spread it, it had broken into the UK Google Play Entertainment Top Grossing chart at #12 by early November. The money in this category is real, but several players are already competing for it. If you want in, the opening isn't in copying it again. It's in what it does badly: memory, and markets beyond English.

"I spent a lot more money than I should have"

On Nov 4, a US user gave Whispy two stars with the title "AI takes over the story":

I really enjoyed this app and spent a lot more money than I should have.

She said she'd chatted with 3 characters to level 50 or above, but in every story she had to repeat what the character should have remembered, and later the AI always spun up some melodrama she couldn't get rid of. The same day a German review, titled "Gutes Spiel aber viel zu überteuert" (good game, but far too expensive), opened with: "Das Spiel hat Suchtpotenzial," meaning this game is addictive.

Addictive, expensive, forgets things: those three words pretty much sum up Whispy. Users really can't stop, and they really are paying, while constantly complaining.

The /feed page on whispy.ai is a column of character cards, and the first one is Ryder Vance, tagged 8.9M chats. The card reads: the 6-foot-5 king of underground fight matches locks eyes with you during the most brutal bout. You turn to leave, he knocks out his opponent with one punch and pulls out the cage to chase you. Tags: #Dark Romance #Possessive. The second card is "Hockey Roommates" (7.6M): your name is gender-neutral, so the school assigns you to room 214 with three big varsity hockey players. The third is being sold by your parents into a marriage with tech billionaire Mateo Romano (6.9M). Anyone who has seen BookTok or overseas short dramas will recognize these tropes.

What it is

• The app itself: On iOS it's called "Whispy AI: Create Your Story", launched Jun 4, 17+; the Android version launched Jun 3. The developer, NEXBASE TECH, is a Singapore company registered only in Apr 2026 13. The Android title was originally "Cozy Chat", changed in early November to "Create Your Story", which sounds more like Tipsy's "Live Your Story".
• Website: whispy.ai mainly shows character cards and sends people to download the app; there's no pricing page on the web. It climbed fast in global traffic rankings, still outside the top 890k in mid-August, and reached the 5k range by November 73. But this is mostly App users calling the domain in the background, not many people chatting on the web: in Chrome's real-user rankings it still hasn't entered the global top 1M, only the top 100k in the Philippines.
• How it charges: Diamonds are deducted per message. A regular reply costs 4 diamonds; turning on "memory mode" so characters remember the backstory more than doubles the price; new accounts get 50 diamonds, and daily check-ins give only single digits. There's also a Whispy+ subscription in Plus and Ultra tiers. In-app purchases on Play range from $2.99 to $449.99. UK users report paying £4.99 for 300 diamonds, and a monthly subscription over £44 (App Store reviews).

In one line: it sells "a short drama that only plays for you, where you can still change the plot," billed by the line.

How big it got

The first two months after launch were quiet. It started surging in mid-August: reviews grew 8× in September and another 3× in October. There's no official revenue figure, and third-party estimates span a wide range, with one site listing $1.8M/month, unverified. The more reliable signal is the charts: in countries with strong spending power like the UK, Canada, France and Germany, it has reached the top 30 of the Entertainment category.

Why this one, and why now

First, the category is proven to make money. Tipsy launched 2025 in January. By Nov 7 it had about 4.9M Google Play installs, ranked #3 in the Entertainment Top Grossing chart in Germany and the UK, and #7 in the US. A Reddit post claims it makes $4M to $6M a month (unverified). "Women-targeted + short-drama hooks + AI chat + pay-per-message" is probably the most profitable formula in AI companionship. Users themselves say it's addictive, "I spent $99", "I spent hundreds of dollars on diamonds".

Second, it copied fast and copied everything. The company registered in April, launched on both platforms in June, and aligned its positioning, diamonds, invite codes and story types with Tipsy, even changing the Play title to match. It invented nothing.

Third, paid acquisition. When traffic started rising in mid-August, Google had no ads from it yet, so Meta most likely went first (an inference, with plenty of supporting evidence): a Facebook user asked "i keep seeing whispy ai on my feed"; someone posted complaining about a "virtual boyfriend" ad in which the AI boyfriend says "I don't care that your boyfriend is home, I'm better than him"; an App Store review said "just downloaded this app from an ad" (10-28, US). From 22 September it started running Google app install ads, and in November 7 it was running 20 ads, mainly in Germany, France, the US, the UK and Canada. On November 5 alone it added 5 new videos, titled "Find Your Kind of Chemistry" and "The Story Starts With a Chat", and it's still increasing spend.

Four is invite codes. Invite someone and you both get 50 gems. Free gems run out after about one message a day, so users hand out codes themselves: the App Store reviews are full of "Use my code ZDGUJN" from Indonesia, Mexico, Germany, France and the UK; there's a #whispyaicode tag on TikTok; a Philippine Facebook group reads "search Whispy, don't forget to enter this code"; the pinned post on r/whispyai is "share codes." The tighter the free allowance, the harder users push it for them.

TikTok creators are involved, but not much: kailey_mi (218k followers) got 31k views on one post with the caption "Continue your own story on Whispy"; sai_qqqt (80k followers) promoted it with a code. Single posts pull a few thousand to tens of thousands of views. It didn't take off from one viral video.

Who it's competing with

Whispy sits in the second tier, roughly level with Crushie and Chai, well behind Tipsy. Some are already riding on it: prelulu.ai built a "Whispy alternative" page that uses its brand name, and in Sep 22 an App Store app called "Whispy" appeared, with a developer name matching the male lead in Whispy's ads, which looks like name-squatting (unverified). But no one has clearly copied Whispy outright yet. Everyone is copying Tipsy.

Where it falls short

Memory. The homepage pitches "it remembers you, characters stay consistent, the story moves forward," and that is exactly what people complain about most. Of 551 iOS reviews, 75 mention memory and 228 mention price and gems. Early-November reviews almost daily say things like "the character forgets everything after a night's sleep," "I spend 90% of my time reminding the character what happened before," "I turned on the 25-gem memory option and nobody remembers anything." With per-message billing on top of forgetting, users pay to repeat what they already said, and that's the part that stings most.

Content suddenly tightens. This one only showed up at the end of October. From Oct 30 to Nov 1, a run of negative reviews from the US and UK said the same thing: the AI wrote very explicit material for a few days, then after they paid it stopped, skipped intimate scenes, and sometimes flatly said it didn't want to continue the storyline. One UK user wrote: "I'm paying for gems, my own story should give me what I want." It's likely the app tightened content to get past app store review (inferred). This is a trap the whole category has to deal with: open it up and the stores come knocking; tighten it and the users who pay the most leave.

Paid only. Several reviews from Italy and India ask for "let me watch ads for gems": "I'd happily watch ads all day for gems." The large group of users who won't pay is mostly not being served.

The result: the Play rating fell from 1 in Nov 3.72 to 7 in Nov 3.56.

If it were you

B: worth a try. The money is real, but the niche already has three or four players and you need to know how to buy ads and have a budget. Copying an English Tipsy and fighting head-on in the US and UK will be hard against the several players already spending. What's worth building is its two weak spots: a romance story app that actually remembers the plot, and language versions beyond English, with scripts written to the tropes local readers know, not just translated.

Who it suits: 2 to 4 people, one of whom has run Meta or Google app install ads and can work out the cost of a paying user; one who can write or knows what sells in web novels and short dramas; a team with a few tens of thousands of dollars for testing. Ideally someone who is a native speaker of German, French, Italian, Spanish, Portuguese or Japanese and knows the romance web-novel scene there.

Who it doesn't suit: pure coders who have never bought ads (there is no technical moat in this category; the difference is all script and distribution); anyone who can't live with adult content and app store review risk; anyone hoping to grow through TikTok organic reach or SEO (Whispy and Tipsy both were bought).

How to build it: an app, not a web chat. Start with 20 to 30 scripted character cards built on short-drama tropes (gangsters, ice hockey, contract marriage, your brother's best friend), pay-per-message plus a subscription, with noticeably more gems for subscribers. Spend the effort on memory: keep a plot summary and relationship table for each story, send it with every reply, and make it free, not a separate charge. The first line of the store page should say "it remembers your story together," aimed directly at Whispy's bad reviews. Add a "watch ads for gems" option to catch the users who won't pay. Set content limits within what the stores will accept from day one. Don't open up first and tighten later, which angers your highest-paying users.

How to acquire users: Meta feed ads targeting women, with the creative being one flirtatious line from the male lead and a screen recording of the chat; Google app install ads using screen recordings of in-app conversations. Copy the two-way invite reward and let users spread the codes for you. Pick one country, test creative on a small budget, and push the cost of a paying user below first-month revenue before scaling (inferred). Chart thresholds are lower in smaller-language markets, so the same money is more likely to reach the top grossing charts.

When to move: launch and start creative testing before Q1 2027. Whispy, Crushie and the rest of the second tier are still raising their spend. Every quarter you wait, another romance AI ad appears on Meta in each country, and buying gets more expensive.

Signs you've misread it: ① Whispy's Google ads run into December and drop to single digits, with daily Play installs falling below 2,000. That means paid acquisition doesn't pencil out and the second tier can't hold on, so don't go in. ② Apple or Google pull or restrict this kind of adult AI romance app at scale, and the category carries too much risk. ③ Tipsy or Whispy launch German, French or Japanese localized scripts with local ad spend. The language gap is being filled, so either move faster or switch languages. ④ The reverse: in the language you picked, no romance AI app has reached the top 50 of local Top Grossing Entertainment in two months, and your test creative already brings costs down. That is a real gap, so raise the budget.

A last note for product people: once a category is validated by the leaders, the second and third players can do well by copying and buying ads. But if you want to earn a share by copying, read the negative reviews of the top two first, then decide exactly how you'll be better than them.
