Pick the assistant you already pay for — ChatGPT, Claude, Perplexity, Gemini or Grok — and send it a ready-to-run brief that builds a complete, sourced company dossier. No key, no install: the model does the work in its own tab, guided by the Company Dossier method.
Type a company, choose a model. We open it with the nine-section prompt — and copy it as a fallback.
Opens your chosen AI in a new tab. Perplexity & Grok run it automatically; ChatGPT fills the prompt (press Enter); Claude & Gemini open with the prompt copied — just paste. The full prompt is always copied to your clipboard as a backup, and shown above after you click.
This hands a prompt to your own AI — the chat does the research in your account, and quality depends on that tool. Want a structured, sourced dossier returned automatically for an app, agent or script? That's the MCP server & API → (the same engine behind the free in-browser generator).
Claude Code & Codex open the agent installed on your machine with the prompt ready — press Enter to run. (Requires them installed; the prompt is copied as a backup.)
Every button builds the same brief: it tells your assistant to produce a Markdown dossier across the nine Company Dossier sections — overview & identity, people & org chart, hiring radar, money trail, locations, tech fingerprint, news & timeline, relationship web, and risk flags — using public sources only, attributing every claim, and marking gaps. The prompt points the model at https://companydossier.lol/llms.txt and the open-source method so it follows the same playbook the CLI and VS Code extension use.
For a structured file with no copy-paste, use the in-browser generator (bring your Claude key), the npm CLI (npx company-dossier <company>), the VS Code extension, the MCP server / API (connect any agent to build_dossier), or wire the Claude / ChatGPT apps via the built-in MCP server (tool build_dossier).
