YOUR LIBRARY / ACCOUNT
Your Design Tools account.
Free access
Sign in with izzy.la for full library write-ups and keys for your agents. This is the design-library account; the desktop preview uses your own model credentials separately.
Checking your sign-in…
Not signed in.
Without an account you still get the catalog, every blueprint, and the free writeups. Signing in opens the rest.

SaturnAI Pro
Pro, $8 a month. Everything above stays free. Pro raises your hourly limit on the hosted API and MCP from 600 to 3,000 calls, and it pays for the free library.
Payment is handled by Stripe. Cancel any time from this page; Pro stays on until the end of the paid month.
