Questions
What does "all features" mean during early access?
Every lens, every specialist, every analysis tool. The only limit is 50 managed AI actions per month — not what you can do. You get the full Cairn experience with unlimited projects and nodes.
What is BYOK?
Bring Your Own Key. Plug your Anthropic and Gemini API keys into Settings. Your calls go directly from your browser to the AI provider — no metering, no limits. Your keys never touch our servers.
What happens when paid plans launch?
All your projects and data stay accessible. You'll get at least 30 days notice before any changes. We will never delete or lock your existing work.
Is my data safe?
Your models live in your browser by default. Cloud sync is optional. All data in transit is encrypted. Row-level security means only you can access your projects. You can export everything at any time.
What counts as an AI action?
Each AI pipeline call (decompose, analyze, generate brief, etc.) counts as one action. Image generation counts as one action. BYOK calls are unlimited and never metered.
