AI coding agents can build a working page or deck, but in the founder's words their visual output often looks generic.

It launched in October 2025. By then, Anthropic's Claude Code had made skills, slash commands and subagents a normal way to steer a coding agent. Most developers were still writing their own.

It turned a new working habit into a native Mac app. The habit was running several AI coding agents at the same time.

Stripe recorded more than three quarters of the revenue in the first seven weeks.

The compression engine already existed as a free, open-source Python tool, but it was hard to install. Garm Lucassen packaged it into a desktop app. The app installs with a double click, connects the coding agents by itself, and removes its changes when it quits.

The free part does what the market leader charges for: unlimited game reviews, where Chess.com gives free users one a day. Because the engine runs on the player's device, each free review costs Chessigma almost nothing. So the free tool could grow to about 900,000 visitors a month. Revenue started only when the AI coach went on sale in May 2026: TrustMRR shows US$42 in April 2026 and US$3,738 in May 2026.

A developer in Bangalore formed a company with an American YouTuber who already had an audience of people who want faceless channels. So customers paid from the first day.

Verified revenue reached about US$85,000 a month for six months, and then fell by half.

It took a narrower job than the general AI design tools, mobile apps only, for people who build apps without design skills.

One researcher had led AI-guided optics design at Alphabet and Meta. He put the tooling of that field into the open, with a shared benchmark that anyone could run. Apple, which designs cameras, displays, sensors and lidar parts, bought the assets and hired him. The buyer's filing with the European Commission is the only hard document; it gives no price.
