Questions
What does "all features" on Free mean?
Every lens, every specialist, every analysis tool. Free limits are on scale (projects, nodes, AI calls) — not on what you can do. You get the full Cairn experience.
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 if I downgrade from Pro to Free?
All your projects and data stay accessible. Free tier limits apply to new creations only. We 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.
When will payments be available?
Right now all users get Pro features for free. Paid tiers will be introduced when the product is ready for general availability. You'll get at least 30 days notice before any changes.
