Frequently asked questions
Important questions before trial and purchase.
Is the application limited to Spencer-Brown forms?
No. It specialises in form calculi and re-entry structures while also supporting flexible relational modelling and SVG editing.
Can I continue projects later?
Yes. Projects are stored locally as JSON files and can be loaded again.
Does the application validate academic correctness?
No. The studio is a construction and visualisation tool; sources, interpretation and subject-matter correctness remain the user’s responsibility.
