Cantrip AI

Cantrip turns a sentence into a small, single-purpose tool. Describe what you want and the AI on your phone builds it: a timer that chimes every thirty seconds, a counter for one specific thing, a checklist shaped the way you actually work.

Instead of another icon, each tool gets a symbol you draw yourself. Draw that symbol on the home screen and the tool opens. Tap it in the list if you'd rather.

EVERYTHING RUNS ON THE PHONE The model that writes your tools is downloaded once and never talks to a server. No account, no sign-in, nothing uploaded.

CHANGE ANYTHING BY SAYING SO "Make the text bigger." "Add a reset button." "Beep every second." The tool gets rewritten in place.

Send one to someone and it travels as a single small file. They draw their own symbol for it.

• Describe a tool in plain words
• Open it by drawing, or by tapping
• Adjust it later by describing the change
• Works offline
• No accounts, no ads, no subscriptions, no tracking
• Seven tools included

Requires an iPhone with 8 GB of memory (iPhone 15 Pro or newer). The model downloads once over WiFi, about 2.5 GB.
