Questions
Can I use Chinilla without paying?
Yes. The free tier gives you the full canvas, all components, templates, runtime simulation, all exports (PNG, Python, Spec, JSON), and unlimited cloud saves with a free account. No payment needed. Pro adds AI features: chat, stability analysis, stress controls, AI code export, AI PRD, and subsystems.
What counts as an AI credit?
Any AI action uses 1 credit: chat messages, AI-generated designs, stability analysis, Python code export, and PRD generation. Deterministic exports (Python, System Spec) and runtime simulation do not use credits. Credits reset on your billing date each month.
Can I cancel anytime?
Yes. Cancel from your dashboard. You keep all designs (local and cloud) forever. AI features stop working but your data is always yours.
Do you train on my designs?
No. Your designs are never used for model training. AI features use xAI's Grok on a per-request basis with no data retention.
