Built for researchers, recruiters, real-estate agents, e-commerce analysts, and anyone who works with web data.
Any AI model
Works with OpenAI, Groq (free tier), Ollama (fully local), OpenRouter, and any OpenAI-compatible API. Bring your own key.
Custom sessions
Create multiple named sessions — one for job listings, another for real-estate, another for competitor prices. Switch with one click.
Export anywhere
All collected records are stored locally and can be exported to JSON or CSV for use in Excel, Google Sheets, or any other tool.
Privacy first
Your data never leaves your browser except to the AI API you choose. No cloud sync, no account required, no tracking.
LLM hints
Add optional hints per field to guide the AI — e.g., "extract only the base price, ignore VAT" — for more precise extraction.
Call log & debug
Every AI call is logged with model, status, duration, and full prompt/response. Inspect or export the log at any time.

Common questions
Do I need an OpenAI account?
No. Collectorium works with any OpenAI-compatible API. Groq offers a free tier with no credit card required — we recommend starting there. You can also run models fully locally with Ollama at no cost.
Where is my data stored?
All collected records are stored locally in your browser's extension storage. Nothing is sent to our servers — we don't even have a backend. Your data is yours.
Which Chrome versions are supported?
Collectorium works on Chrome 114+ and any Chromium-based browser (Edge, Brave, Arc). Firefox is not supported due to extension API differences.
Can I use it on any website?
Yes. Collectorium reads the visible text content of any page. It works best on pages with clear, structured text. Paywalled or login-protected pages work too — as long as you're logged in, the extension sees what you see.
What if the AI fills in something wrong?
You can review and manually edit any field before saving. The AI is a fast first pass — you're always in control of the final record.
