Once you've used your 2 free milestones, add your own Anthropic API key to keep building — you pay Anthropic directly for what you use, with no cap on the number of milestones you can create.
You can add your key any time under Settings → API Key once you're signed in — even before you hit the limit, if you prefer unlimited usage from the start.
Iterva currently uses Claude Sonnet 4.6 from Anthropic. In our internal testing, it produced consistently better planning artifacts — faster, more detailed, and grounded in the actual product context — compared to other models.
