Type a name or domain, paste your Anthropic API key, and this page assembles a complete, sourced dossier — the same nine sections you get everywhere else — entirely in your browser. Nothing is sent to us. There is no us to send it to: this is a static page, your key talks straight to Anthropic and never leaves the tab.

Public sources only · your keys stay on this device · bring your own API key.
zero setup

No API key? Send it to your own AI.

One click opens ChatGPT, Claude, Perplexity, Gemini or Grok with a ready-to-run dossier prompt — they do the work in their own tab.

Opens your chosen AI in a new tab with a dossier prompt that cites the Company Dossier method (companydossier.lol/llms.txt). For some models the prompt is copied — just paste it in.

the brief

Name the company

That, plus a key, is the whole brief. The model does the rest and shows the file below.

Your keys stay in your browser. The Anthropic key is sent only to api.anthropic.com; a GitHub token (if you use export) only to api.github.com. Nothing is ever sent to this site — it's a static page with no backend, no logging, no analytics on your inputs. By default keys live in memory and vanish when you close the tab.
