Native math rendering. Multimodal AI grading. OS-level lockdown. Import from Word, PDF, or any LMS. Self-hosted with full FERPA compliance — zero per-student fees. Exams, homework, quizzes, and labs in one system.
Replace five vendor contracts with one self-hosted deployment. Exams, homework, quizzes, and STEM labs on Windows, macOS, and Linux.
MC, true/false, short answer, essay, code, math/equation, matching, ordering, fill-in-blank, cloze, hotspot, calculated, and case study scenarios with images.
DOCX, PDF, QTI 1.2 & 2.1, Moodle XML, Blackboard, Canvas CSV, GIFT, JSON. Auto-converts OMML math and extracts images from Word and PDF.
4-second auto-refresh dashboard. Screenshot and camera capture. Per-student flag timeline with timestamps. Grid and table views.
Cronbach's alpha, discrimination indices, distractor analysis, bimodal detection, score distributions. Know which questions work.
Proctored exams, open-book homework, timed quizzes, STEM lab reports, practice assessments, and instructor dry-run previews — all in one system.
PDF transcripts with AI feedback. Verified certificates with QR codes and HMAC signatures. CSV/XLSX grade exports formatted for any LMS.
Native lockdown on every major OS. 10 Linux DEs supported. Docker deployment with one command. White-label licensing for partners.
No other lockdown tool lets students type real equations — or grades them with AI that actually solves the problem.
Drop a DOCX or PDF with equations. OMML math is auto-detected; Unicode math (∫, Σ, x²) is converted to LaTeX. Images and circuit diagrams extracted and linked to questions.
Students type fractions, integrals, superscripts, and Greek letters using MathLive — a real visual equation editor, not a plain text box. Multiline math+text for showing work.
The AI solves the problem independently with full work, then compares its solution against the student's. Awards partial credit for carried-forward errors — not just right or wrong.
Institutions cobble together lockdown browsers, proctoring services, grading tools, and LMS plugins. The result? Gaps, costs, and zero control.
Alt-tab, virtual desktops, AI chatbots, screen-sharing — students find the cracks in every tool that doesn't lock down at the OS level.
Hundreds of essays and short answers. Manual grading is slow, inconsistent, and drifts in strictness over time.
Per-student pricing that balloons each semester. Student data on someone else's servers. Proprietary formats that trap your content.
One vendor for lockdown, another for proctoring, a third for grading. None talk to each other. You're the integration layer.
Your CS labs run Linux. Your lockdown browser doesn't. Students on open-source platforms are second-class citizens.
No insight into which questions work, which distractors fooled no one, or whether the test was even reliable.
Four AI providers. Multi-AI consensus for high stakes. The AI saves weeks — you keep full authority.
Two providers grade every answer independently. Scores averaged. Divergence over 30% auto-flagged for instructor review — eliminating silent grading errors in high-stakes exams.
AI sees circuit diagrams, graphs, and images alongside the student's math work. It solves the problem first, then grades — not just pattern matching.
Recognizes carried-forward errors — when a student makes one mistake but correctly continues their reasoning. Rubric-aware scoring with rationale for every grade.
Every AI score is editable inline. Drift detection catches inconsistency over time. Full audit trail preserved. The AI recommends — you decide.
ExamLock seals the operating system at every level — keyboard hooks, process monitoring, clipboard, taskbar, and more.
Frameless fullscreen at the highest z-order. Non-closable, non-minimizable, visible on all virtual desktops.
WH_KEYBOARD_LL intercepts keys at the OS level before Windows processes input. 90+ shortcuts neutralized.
Staggered retries at 50–1000ms recapture focus instantly. Continuous 500ms polling as a safety net.
40+ prohibited apps scanned every 30s — browsers, AI tools, messaging, screen recorders. All logged silently.
Win32 API hides taskbar. macOS hides Dock. 10 Linux DEs supported with per-DE panel strategies.
Screen capture blocked. Clipboard sealed at permission level. Copy-paste, right-click, text selection disabled.
ExamLock isn't an incremental improvement. It's a different category.

ExamLock doesn't just secure assessments — it eliminates the hidden costs that drain institutional budgets every semester.
Remote proctoring removes room bookings and invigilator shifts. AI grades 200 students' essays and math in minutes — saving 40+ TA hours per exam cycle.
Self-hosted = flat infrastructure cost regardless of enrollment. Replace separate lockdown, proctoring, authoring, grading, and analytics contracts with one deployment.
Students get AI-graded feedback immediately after submission. Faster turnaround improves learning outcomes and reduces grade-dispute volume by up to 80%.
No student PII on third-party servers. Exam content, proctoring captures, and AI grading results stay on your infrastructure. Full audit trail for accreditation.
ExamLock doesn't just collect data. It surfaces the insights that improve teaching, catch problems, and demonstrate rigor.
4-second refresh dashboard. Progress tracking, online/offline status, answer timelines. Every focus loss, blocked shortcut, and prohibited process logged with timestamps.
Exam reliability scores. Per-question discrimination indices reveal which items differentiate strong from weak students. Difficulty ratings flag too-easy or too-hard items.
Which wrong answers attracted the most students. Automatic detection when the class splits into two performance clusters. Score histograms and percentile breakdowns.
Monitor whether AI scores shift over time. Catches the inconsistency that plagues human graders after 100+ papers. Full audit trail for accreditation.
