Free online AI data extractor: pull structured JSON (names, dates, amounts) out of any text — 100% on your device, no upload, no account.

🔒 Runs entirely in your browser — your files never leave your device.

About AI Data Extractor

AI Data Extractor pulls structured data out of unstructured text — invoices, emails, notes — and returns clean JSON, using an AI model that runs on your own device. Choose between Chrome's built-in AI (Gemini Nano, when available) and an open model compiled to WebAssembly (LFM2.5-230M/350M or MiniCPM5-1B — your choice), which works in any modern browser. The WebAssembly model (146-656 MB depending on choice) is downloaded once and cached locally.

How to use AI Data Extractor

  1. Drop your file(s) into the upload area, or click it to browse.
  2. Adjust the options if needed.
  3. Click the action button and download the result — processed locally, in seconds.

Frequently asked questions

Is AI Data Extractor really free?

Yes — completely free, with no account and no usage limits. The AI runs on your own device.

Is my text sent to a server?

No. Both engines (Chrome's built-in AI and the local WebAssembly model) run entirely on your device. Your text never leaves your computer.

Which browsers are supported?

The WebAssembly model works in any modern browser (Chrome, Firefox, Safari, Edge). Chrome's built-in AI additionally requires a Chrome version that ships the on-device model.
