A handwriting notebook that reads your ink — math, diagrams, code, plain questions — and replies right on the page. Best on iPad with Apple Pencil, but works on any tablet, on a computer with a mouse, or just by typing. Bring your own API key. No subscription.
Apple Pencil or finger on an iPad, mouse or trackpad on a computer, or skip the ink entirely and just type into the text bar — same grid-paper canvas either way.
Reads handwritten equations, physics setups, and graphs, then answers with typeset math and drawn-out figures of its own.
Use your own Anthropic, OpenAI, or Gemini API key. You pay the model provider directly, at cost — Co-Wryte never marks it up.
Keep separate notebooks per subject or project, switch between them, and export any page as a PDF when you're done.
It's the credential that lets Co-Wryte talk to an AI model (Anthropic, OpenAI, or Google) on your behalf. Bringing your own means you pay the model provider directly at their normal rate — Co-Wryte's $20 is just for the app, not a markup on every question you ask.
Any modern browser. It's optimized for iPad with an Apple Pencil, but works on any tablet, on a computer with a mouse or trackpad, or without any handwriting at all — just type into the text bar. One license activates on up to 3 devices.
No. $20 once, and it's yours — including future updates.
Right here. Enter the license key from your purchase email the first time you open it.
