// ascii canvas
Any page → editable wireframe
Click jam on this to flatten a component into an ASCII wireframe. The wireframe is exported alongside your comments — just paste everything into your AI CLI of choice.
// privacy
Your data stays on your machine.
No servers. No accounts. No cloud sync. No "we value your privacy" 47-page PDF.
Just a Chrome extension and your local IndexedDB.
☐
Zero network calls
Your annotations never leave the browser. We don't need 300 third-party SDKs to render ASCII box-drawing characters. Shocking, we know.
⚙
Optional telemetry
Anonymous usage stats (which tools you click, not what you type). Off by default. One toggle in settings. We'll survive without your data.
▣
Manifest V3
Minimal permissions. No background persistence. The extension can't read your tabs unless you click it. We're not that nosy.
$ curl https://design-jam.io/api/telemetry 404 Not Found // there is no API. that's the point.
// pricing
No subscription. Ever.
