How do I connect OpenAI?

Use an OpenAI API key (the platform kind, not ChatGPT) as dossier's AI provider.

dossier speaks to OpenAI’s API directly — useful if that’s where your credits or your company’s accounts already are.

Get a key

  1. Sign in at platform.openai.com.
  2. Create an API key (starts with sk-). This is the platform API — a ChatGPT Plus subscription won’t work here; the API is billed separately, per use.

Connect it

  1. In dossier: Settings → AI → Provider: OpenAI (Codex).
  2. Paste the key — it goes into the macOS Keychain, never into a file.
  3. Pick a model from the live list (newest first, e.g. gpt-5).

dossier uses the same careful data policy with every hosted provider: only the text snippet needed to classify a document is sent, never the file itself — and never anything at all unless you trigger an AI action.

Prefer that nothing leaves your machine? Use a local Ollama model instead.
