Questions
What’s free?
The whole simulator: schematic capture, every analysis, imports, exports, sharing and collaboration, with no limits. Free accounts also get a small monthly assistant allowance on Luna.
What are AI credits?
Credits measure assistant usage. One credit is a tenth of a cent of model cost, and stronger models use more per request. Allowances renew every month and don’t roll over.
Who can use Student pricing?
Anyone signed in with a school email address, such as one ending in .edu or .ac.uk.
What happens when I run out?
The assistant pauses until your allowance renews, or you can upgrade. The simulator keeps working.
Can I cancel or switch plans?
Yes, from Manage billing. Upgrades apply right away and are prorated. Downgrades and cancellations take effect at the end of the period you’ve paid for, and you keep all your designs.
Do you offer SSO or invoicing?
Yes. Enterprise and classroom plans include single sign-on with Okta, Microsoft Entra ID or Google Workspace, and one invoice for every seat. Contact sales to set it up.
