166 tools Nothing uploaded Works offline once opened
One platform, 166 doors into it. Every tool runs on the same engines, the same browser runtime and the same rules: it opens instantly, computes on your device, and behaves the way the last one did. Nothing is uploaded and there is no account to make.

These are not 166 separate tools
They are one platform with 166 faces. The computation lives in 24 shared engines, the interface and the privacy contract belong to the platform, and a tool is mostly a declaration of which engine it runs on.
- 24 engines, 40 patterns The maths lives in a tested engine, not in a page, so a fix lands for every tool on it at once.
- One runtime, loaded once Copy, saved state, search, shortcuts and dark mode are the platform's. Each page then loads only its own engine.
- No server to send anything to There is no application server and no database behind any of it. The engines run in your browser.
- Budgets enforced by the build Every page has a byte budget. A change that makes one heavier than its budget fails the build.
