A web app that designs the screens of an iPhone or Android app from one sentence or a reference image, with AI. You chat to change the design, then paste it into Figma as editable layers, export HTML or React code, or send it to an app builder. AI coding agents can also use it through an API.

It took a narrower job than the general AI design tools, mobile apps only, for people who build apps without design skills. The three founders reused what they had learned from four earlier design tools, built it in three weeks, and showed finished designs on X before the launch. Each new Gemini model gave them a better result and a new demo to post.

A desktop app and Roblox Studio plugin that builds parts of a Roblox game from a written request: game systems, user interfaces, animations, visual effects, sounds and 3D builds, written straight into the user's project after the AI has read it. Users pay for AI tokens with a monthly plan or one-time top-ups, and can install ready-made systems from a marketplace.

The founder had made Roblox games for nine years, with 200 million visits on his own games, and his launch post on the official Roblox developer forum was read 112,656 times. He launched free, with 1 million tokens a month, and charged US$20 a month for heavy use. Then he added top-ups and a marketplace of tested systems that the AI installs, instead of writing every system from nothing.

A web app that turns a short form, or a business name found on Google, into a complete WordPress site for a local business: a page for every service and service area, AI-written text and images, search settings, hosting on its own servers, and an AI agent for later edits. Agencies sell the sites to their clients as their own work.

The founder had sold this product by hand in his own agency, so he knew what agencies deliver: WordPress, a real page builder, and pages for each service and each town. The tool fills designer-made templates with AI text, so the output is consistent. It sells to agencies that build sites every month, which fits a monthly subscription, and it found them through his own posts and videos, with no ads.

A customer enters a website address. SEObot reads the site, chooses search phrases, makes a plan of articles, writes the articles with language models and publishes them to the customer's blog every week. The customer pays a monthly plan of article credits and can approve, edit or decline each article.

The founder had about 117,000 followers on X and more than 20 other products for the same customers, so the tool had buyers before it had a public launch. It sold a finished result, a published article, for about US$3.50 to US$5.44. Payment records show about US$100,000 a month at the end of 2025 and a fall in every month since January 2026.

A company uploads its documents or gives its website address. Chatbase turns that material into a chat agent that answers customer questions on the site, by email or by phone, and hands the conversation to a person when it cannot answer.

It launched the obvious application of a new model within weeks, with a pricing page on the first day. The founder built the parts around the model instead of a model, so every model upgrade improved the product for free. Then it moved from a consumer toy to business customers who stay.

You describe a business idea, or you let the product choose one. Polsia then creates a company name, a website, an email inbox and a payment account. Its AI agents write code, send sales emails, post on X and run Meta adverts. One agent chooses one task every night, does it, and emails you a report.

The founder made his own fundraising the advertisement. In February 2026 he let the product answer investor emails in public, next to a live revenue counter. A new customer needs only an idea, so thousands of people tried the product each day. The counter annualized all money that entered the platform, so it grew faster than the subscription revenue.

An iPhone app for makeup. The user uploads a selfie without makeup and a photo of a makeup look, for example from TikTok or Instagram. The app's AI applies that look to the user's own face, then gives a step-by-step routine and a list of products to buy. It is free to download and paid for with subscriptions through the App Store.

Its result is a before-and-after picture of the user's own face, which a short video shows in seconds. The founder chose TikTok as the channel before he built the app, then tripled revenue from almost the same installs by moving and testing the paywall with Adapty.

A web app for real estate agents and photographers. The agent uploads a photo of a room, chooses the room type and a furniture style, and gets back the same room with furniture in about 10 to 15 seconds. It can also remove existing furniture. Plans are monthly subscriptions sized by the number of photos, and the top plan includes an API.

In 2023, general image generators that were asked to furnish a room also changed the room: the founder said DALL-E might turn a window into a wall painting or add a door, which misrepresents a property. VSAI's own model finds the floor, the ceiling, the mirrors and the doors first and only then adds furniture. It cost US$12 to US$69 a month in early 2024, while VSAI's comparison page lists other staging services at US$16 to US$29 per photo with 12 to 48 hours of waiting. Zillow, the listing portal where such photos end up, bought it.

You photograph your meal. Cal AI sends the picture to a rented AI model and returns an estimate of the calories, protein, carbohydrates and fat. No search, no portion menus.

It sold speed to people who gave up on manual food logging, it paid 250 influencers fixed monthly fees to reach them, and it had a 30-dollar-a-year price. The rented model made the hard part cost almost nothing to build.
