Pricing and API
opnai tools are free to use. There is no paid plan and no watermark. An account is optional: it keeps your results and gives you API keys.
Tools
Free
Every tool works without an account. Daily limits apply to each tool so the GPU stays available for everyone.
Storage
5 GB
Signed-in results are kept permanently in Media, up to 5 GB per account by default. Anonymous results are deleted after 24 hours.
API keys
For developers
Create a key for your own scripts. Each key has its own scopes and daily limit, and you can revoke it at any time. Apps you connect get their own key the same way.
Using opnai from an AI assistant
Claude, Claude Code and other MCP clients can create and edit designs in your account. The setup steps are on the AI integration page, and Connect an app explains how app connections work.
