AI Providers
CRAFT Studio supports three AI providers. All can be active at once — pick per-request from the model dropdown. Keys are stored per user and managed from Profile → API keys in the sidebar.
Free model
Every signed-in account has access to a built-in free model for script writing, ideas, and revisions. It shows up as Free in the model picker and works without any key — useful for exploring the studio before you decide which paid provider you want to add.
Gemini (Google)
Paste a Gemini key under Profile → API keys → Gemini.
Get one at ai.google.dev.
Characteristics
- Streams responses in real time
- Good for quick iterations
- The free Gemini tier is usually enough to try the studio end to end
Claude (Anthropic)
Claude signs in with a long-lived token from your Claude subscription, not a paid API key. Generate one at claude.ai/settings/tokens and paste it under Profile → API keys → Claude.
No API credits needed
The token uses your existing Claude subscription. Premium accounts get the full Claude model family (Opus, Sonnet, Haiku) plus research-tool access when a token is saved.
Characteristics
- May use research tools (storytelling, comedy, etc.) during multi-turn generation
- Responses arrive once they're complete (intermediate planning is filtered out)
- Excellent for complex script writing and fact-checking
Model selection
The model dropdown appears in:
- The Script editor's Revise tab
- AI chat
- The Ideas inline context hint
- The mobile app's script detail
All available providers show in the same dropdown, grouped by provider. Providers that aren't set up for your account are disabled with a short reason.
