From literature essays to organic chem, from medical case studies to legal hypotheticals — 14 question types, multimodal AI grading, and OS-level lockdown on Windows, macOS, and Linux. Replace five vendors with one deployment. Zero per-student fees.

Authoring, delivery, lockdown, proctoring, grading, and analytics — unified. Every layer built for the rigor a real assessment program demands, not the 70% that a generic LMS is willing to cover.
Drop a DOCX with equations, a PDF with circuit diagrams, or a QTI export. 9 formats in. 14 question types out — including math, code, and multi-part case studies.
Not a browser trick. Not a proctoring add-on. Real kiosk enforcement with keyboard hooks and process monitoring — on Windows, macOS, and 10 Linux desktops.
Multimodal grading reads circuit diagrams, solves the problem independently, then awards partial credit for carried-forward errors. Two providers cross-check for high stakes.
No other lockdown tool lets students type real equations. No other grading tool actually solves the problem. ExamLock does both — natively, on every supported OS.
The MathLive-powered editor renders live LaTeX as students type fractions, integrals, Greek letters, and multi-step work. The grader doesn't pattern-match — it computes.
Fourteen native question types — designed for the department, not the LMS. Authors write in their discipline's real notation; the grader reads it the same way a TA would.
No more "upload a PDF of your work." No more "paste your code as plain text." Every question type is first-class, every subject is represented, and nothing gets lost in translation.
Every answer graded by AI that actually understands the subject — then cross-verified by a second model when the stakes are high. Every score is editable, every rationale preserved.
Proctors monitor a live grid with four-second refresh. Every focus loss, blocked shortcut, and prohibited process is flagged with timestamps. No third-party vendor. No student data leaving your infrastructure.
Pilot data from three partner institutions across two academic years. Fall 2024 through Spring 2026.
Honest comparison against the four tools most institutions end up stitching together. If a competitor offers a feature we missed, tell us — we'll update the table.

Most lockdown tools are a fullscreen Chrome window with keyboard listeners. ExamLock seals the OS — keyboard hooks, process monitoring, taskbar control, content protection, focus enforcement. On every supported platform.
Frameless fullscreen at the highest z-order. Non-closable, non-minimizable, visible on all virtual desktops — every OS.
WH_KEYBOARD_LL intercepts keys at the OS level before the window manager processes input. 90+ shortcuts neutralized.
Staggered retries at 50–1000ms recapture focus instantly. Continuous 500ms polling as a safety net.
40+ prohibited applications scanned every 30 seconds — browsers, AI tools, messaging, screen recorders. Silent logging.
Win32 API hides the taskbar. macOS hides the Dock. Per-DE panel strategies on Linux (GNOME, KDE, XFCE, and seven more).
Screen capture blocked. Clipboard sealed at the permission level. Right-click, text selection, and DevTools disabled.
A live walkthrough tailored to your department's discipline — math, medicine, CS, or certifying body. We'll grade one of your past exams with AI so you can judge the output yourself.
