Questions
- Do I need a card for the free trial?
- Yes. The 7-day trial on the yearly plan collects a card up front, charges nothing today, emails you on day 5, and bills $59.88 on day 7 unless you cancel — one click from Settings → Manage billing.
- What counts as a diagram?
- One AI draw or edit of your canvas. If the AI only replies with text, nothing is charged.
- What happens when a 7-Day Pass runs out?
- Nothing renews. Unused Pass diagrams expire 7 days after purchase; buy another whenever you need one.
- Can I use my own API key?
- Yes. Add an OpenAI, Anthropic, Google, or OpenRouter key in Settings and generate without limits on the Free plan.
