A DEBARROSLABS EXPERIMENT
A small tool for studying.
OpenTests helps you practise with questions you write or import from Excel. No account is needed. Tests, recent results and an unfinished practice session are saved in this browser.
Keep a copy of your work
Browser data can be cleared, and private browsing may not keep it. Download a backup from My tests. You can restore that file in another browser; your data does not sync automatically. Backups contain your questions and recent results, so share them only when you intend to. Unfinished sessions are not included in backups.
Use material you have permission to use
Bring original questions, your own study notes, public-domain material or content you have permission to use. Do not import real exam dumps, leaked official questions or protected material without permission.
Open source, small by design
The code is licensed under AGPLv3. That licence does not automatically apply to your questions. Accounts, cloud sync, community publishing remain outside this release. Optional PDF generation is a separate one-time purchase. Its free quote runs in your browser; paid generation sends extracted material to Anthropic. Existing local tests stay local.
