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.

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.
