# Collectorium > Structured data from any website — Chrome extension with AI autofill. Collectorium is a Chrome extension that helps you capture structured data from web pages. Define custom fields once, browse normally, and pull exactly what you need into rows you can export as CSV or JSON. Optional AI autofill reads the open tab using an OpenAI-compatible API you configure (your key, your endpoint). Data stays in Chrome local storage until you export. ## Links - Website: https://collectorium.asimplek.cloud/ - Chrome Web Store: https://chromewebstore.google.com/detail/collectorium/nglpgcjmamajcancjjpdaknlfegholoh - Privacy policy: https://collectorium.asimplek.cloud/privacy.html - Terms of service: https://collectorium.asimplek.cloud/terms.html - Refund policy: https://collectorium.asimplek.cloud/refund.html - Contact: kras.algim+collectorium@gmail.com ## Pricing - **Free tier**: Install from the Chrome Web Store.

License key delivered by email after checkout; paste it in the extension to unlock. ## How it works 1. Install the extension from the Chrome Web Store. 2. Open the side panel on any page and create a session with custom fields. 3. Optionally run AI autofill — the extension sends page text to the API endpoint you configured. 4. Review, edit, and save the row. Repeat on other pages. 5. Export your collected data as CSV or JSON. ## Key facts - Data stays in your browser (Chrome local storage) until you export. - AI autofill uses your own API key to an OpenAI-compatible endpoint. - Pro is a one-time purchase, not a subscription. License managed via Polar customer portal. - The extension does not send your captured data to our servers.
