Get Zayeed

Open it in a browser, or install it on the machine in front of you. Every build is the same library, the same engine and the same marks — there is no reduced edition among them.

Web app

PWA · no install

Open it and it works, including offline: the database is a full SQLite replica in the browser's own private file system. Install it from the address bar for an icon and a window of its own.

Windows

desktop · 10 and 11

Adds the three things a browser cannot: a real .mcq file on disk, lockdown mode for an invigilated sitting, and seeing another Zayeed device on the same network so two machines sync with no server involved.

Download · 3.8 MB

Linux

desktop · deb

The same native shell as Windows, with the same lockdown mode and the same direct sync between two machines on one network.

Download · 5.4 MB

Android

phone & tablet

Writes papers as well as sitting them: same sets, same engine, same rules, same statistics, same certificates — and the pack’s on-screen keyboard, so an unsupported script is still answerable. Save and open a .mcq through the share sheet.

Preview build 0.1.0. These are real installers and they run, but Zayeed has not had a stable release. The desktop and Android builds are not yet signed with a purchased certificate, so Windows SmartScreen and Android will both warn you the first time — check the file against the checksum below rather than taking the warning as the last word. Signed builds replace these as each shell reaches release.

Licensing

Zayeed is closed source. Licensing is not open yet and nothing is purchasable — the pricing page explains the shape it will take. Want a build for an estate we have not listed, or an air-gapped deployment? Ask.

Still deciding?

The fastest way to judge a marker is to try to break it. Run a paper, answer it badly on purpose, and read the reason next to every mark.
