Connect your AI

Fluf never resells AI: every connection bills you through your own provider account.

Two ways in

API keys (fastest). Anthropic, OpenAI, Google, xAI, OpenRouter and other major providers. Paste a key, pick a model, go.

Your installed CLIs. Fluf runs your installed Claude Code or Codex, signed in with your own login. You sign in through each app itself and its own terms and limits apply. Fluf never sees your credentials.

Add an API key

1. Create a key in your provider's console and set a budget you're comfortable with.
2. In Fluf, open Settings › AI connections and choose the provider.
3. Paste the key into the key field. Never paste keys into a chat.
4. Name it something you'll recognise: "Personal Claude", "Client B key", "Research budget".
5. Verify it. Fluf lists the models that key can use.
6. Pick which bots use it.

Verification can make one small model request, which your provider may bill. A passing check confirms access today, not a balance.

Use your installed Claude Code or Codex

Install the official Claude Code or Codex CLI and sign in through its own flow. Then choose Use my Claude Code or Use my Codex in Fluf. Fluf runs the CLI you installed; it never sees, stores or proxies your credentials or tokens.

Provider terms, account eligibility and plan limits apply. A plan doesn't unlock every model or paid mode. When you want headroom, add an API key as a fallback.

Muse connects through its supported installed CLI. Pick only the models Fluf lists for that connection.

Several accounts, side by side

Add as many connections per provider as you need: a personal plan, a work plan, a client's key on that client's business. Rename each one. Choose which bots can use which connection. A second connection doesn't raise the limits of the first, and Fluf isn't built to pool accounts around limits.

Keys live in your operating system's credential store. On Linux, that's the desktop keyring (Secret Service), so unlock it first. The connection list never shows secret values.

See usage before it bites

Settings › AI connections shows usage left on every connection, where the provider reports it, and tokens used by every bot. Spot the hungry bot before it eats your week. Move a heavy bot to a cheaper model or a different connection in two clicks.

"Unavailable" means the provider didn't report it: not zero, not unlimited. Fluf's cost estimates are estimates; your provider's invoice is the bill. Keep your provider's own spend limits on too.

Change or remove a connection

Point any bots and routines that rely on a connection at another one first, or pause them. Removing a connection in Fluf doesn't cancel your provider plan or revoke the key; do that at the provider.
