Pricing
Three kinds of account. Every one of them runs the whole app — the difference is whose workspace you work in and how much AI drafting you can use. Without an account you can still build models and generate, verify and export items in your browser.
Training Account
For participants of a cohort opened by an instructor.
- The whole app — diagnosis, generation, exhaustive verification, every export (CSV, JSON, QTI 2.2, Word)
- Model versions saved to the cohort's workspace
- Server-issued certificates
- AI drafting: 10 drafts per day
- When the cohort period ends, drafting closes and saved models stay readable
Professional Account
For individual authors and researchers building their own item families.
- The whole app and a workspace of your own
- AI drafting: 100 drafts per day
- Unlimited generation, verification and certificates
- Every export — CSV, JSON, QTI 2.2, Word, PDF
- Support by email
Institutional Account
For licensing bodies, certification programs and universities.
- Separate workspaces per program, with the seats you need
- Author, reviewer and approver roles
- Audit trail — certificates mirrored the moment they are issued, or fed to your own systems
- Drafting allowance sized to the program, or your own model-provider key (BYOK)
- Invoicing, agreements and data-processing terms
Questions people ask
What counts as one draft?
One request to draft models from source material. Asking the assistant to revise that draft against its measurements counts as another. Daily allowances reset at midnight UTC. Generating, verifying, certifying and exporting are never counted.
Can I use it without an account?
Yes. Entering models, diagnosis, generation, verification and every export work in your browser. An account is needed for three things: saving to the cloud, server certificates, and AI drafting.
What does a certificate prove?
Structural properties of every item and the hash of the set — not domain accuracy or difficulty. The Disclaimer spells it out.
