About this tool
Paste a long article or document to generate a shorter summary using a compact AI summarization model that downloads once and then runs entirely on your device — no text is ever sent to a server.
How to use
- Paste text (it works best on 200+ words of prose).
- Click Summarize. The first run downloads a small AI model to your browser, shown with a progress indicator.
- Read the generated summary; later runs on this device reuse the cached model and are much faster.
FAQ
Is my text uploaded to a server?
No. After the one-time model download, summarization runs entirely in your browser using WebAssembly — your text never leaves your device.
Why is the first use slow, and is it safe on mobile data?
The AI model is around 100–300MB and downloads once, then is cached by your browser for future visits. On a metered mobile connection, consider waiting for Wi-Fi before first use.
