Stop keeping a separate app for every small thing you need. Whittle is one home for every app that matters the most โ€” bring one in, or build one โ€” and it installs, hosts, and launches it right on your phone, fully offline. Already have an HTML file or a zipped web app? Import it โ€” Whittle hosts it locally and launches it in its own sandboxed window: its own icon, its own storage, its own home-screen shortcut. Don't have one yet? Describe what you want, and Whittle writes a carefully engineered prompt for the AI app you already use. Paste the result back and it imports the same way. HOW IT WORKS 1. Bring one in, or describe one. Import an HTML file or a .zip bundle, or pick a starter idea and let Whittle draft the prompt. 2. Hand it to your AI, if you're creating one. Whittle shares the prompt to ChatGPT, Claude, Gemini, Perplexity, Copilot or Poe โ€” or copy it anywhere you like. 3. Bring it back. Paste the HTML, or use the one-tap deep link to import straight from your clipboard. 4. It runs. Whittle hosts it locally and launches it full screen, completely offline. 5. Fix it. "Debug with AI" hands the app's own source back to a model for repair, then updates your installed copy. WHAT YOU GET โ€ข Offline by default โ€” installed apps run from on-device storage with no server and no connection. โ€ข A real library โ€” every app you bring in or create, with size and last-opened details, plus a demo app to start from. โ€ข Isolated storage โ€” each app gets its own private data, so they never clobber one another. โ€ข Shortcuts โ€” launch any app with a single tap, including from Siri. โ€ข Reminders โ€” apps can schedule notifications that deep-link straight back into them. โ€ข Preview โ€” check an app before committing to install. Whittle does not run the AI itself. It works with the AI apps you already have installed, so nothing you write is sent anywhere by Whittle.
