    Which lab and browser — e.g. “Relay Lab, Chrome 138, macOS”.

  3. 03

    What you expected, and what happened — one sentence each is plenty.

  4. 04

    The circuit itself — attach the project file supported by that lab, if available and safe to share.

Browse all FAQs →
Do I need an account to try it?

No. Open a lab and build without an account. Persistence differs by lab: Logic keeps browser-local circuits, Electricity, Analog and Relay each keep one local draft. Sign in for supported cloud saves, unlisted links, gallery features, account tools, and purchases.

Where are my circuits stored?

Browser-local work stays in that browser where the lab supports it. Cloud save, unlisted sharing, gallery publishing, and project-file export are lab-specific; using a server feature stores the circuit data needed to provide it on DigiSim servers.

What are the plans?

Free has no recurring charge. Pro renews monthly or annually, and Founder is a one-time offer while available. Eligible school-email accounts receive 50% off Pro and Founder at checkout. Classroom is a separately confirmed pilot with no self-service checkout.

Can I get a quote or invoice for my department?

Contact education@digisim.io with your institution and seat count to ask about availability. Classroom is limited to a confirmed administrator-invoice pilot for Logic Lab; general purchasing and self-service checkout are not available.
