Bandura’s AI features run on your own Anthropic API key. There’s no credit meter and no middleman — requests go from your machine to Anthropic, on your terms. Everything else in Bandura works without any key at all (including self-healing, which is deterministic and needs no AI).
Add the key
- Open Settings — the gear icon in the activity bar, or ⌘,.
- In the Anthropic API key section, paste your key (it looks like
sk-ant-…). Keys come from the Anthropic Console. - Click Save key.
The key is stored in your operating system’s keychain (macOS Keychain, Windows DPAPI, libsecret on Linux) — not in a config file, not in the workspace, never in Git. Remove key in the same section deletes it.
Pick a default model
Below the key, the Default AI model dropdown selects what powers generation, chat, and
ai-action nodes — Claude Opus 4.8 (the default), Claude Sonnet 5, or Claude Haiku 4.5.
Opus is the most capable; Haiku is the fastest and cheapest for simple prompts.
What the key unlocks
- Generate flows with AI — a sentence in, a runnable flow out.
- AI chat & ai-action nodes — a chat that knows your flow, and a node type that asks the model questions mid-run.
