The 7 Best Online Exam Software Tools for Teachers & Trainers
Compare the best online exam software on AI question generation, built-in proctoring, auto-grading, and price, so you can create secure, auto-graded exams that scale.
The best online exam software does three things well: it helps you build an exam fast, secure it against cheating, and grade it automatically at any scale. Plenty of tools nail one or two of those; far fewer do all three. We compared seven leading options on AI question generation, built-in proctoring, auto-grading, and price, so teachers, trainers, and certification programs can pick with confidence.
Quick verdict: for a modern, AI-native exam tool that generates questions, proctors, and grades in one place, and starts free, Quzo is our top pick. Testportal is the closest feature-for-feature rival, and Google Forms is the go-to free basic option.
What to look for in online exam software
- Question creation: can it generate questions with AI, or do you build every one by hand?
- Proctoring: is exam security built in (identity, lockdown, monitoring), or bolted on?
- Auto-grading: instant scoring, so you're not marking manually.
- Delivery controls: timers, randomization, question banks.
- Price and free tier: what it costs to start and to scale.

The 7 best online exam software tools
1. Quzo: best AI-native exam software with built-in proctoring
Quzo is built for the whole exam lifecycle. Describe a topic or upload your material and its AI generates the questions; add a timer, randomize from a question bank, and turn on built-in proctoring (identity verification, browser lockdown, and monitoring) without a separate vendor. Everything auto-grades instantly. It's the tightest combination of AI generation and native proctoring on this list, and it starts free.
- Best for: teachers, trainers, and certification programs wanting AI + proctoring in one tool.
- Free tier, then $19/mo (Starter).
2. Testportal: best full-featured rival
Testportal is a strong, education-friendly exam platform with an AI question generator, "Smart Proctoring," and auto-grading, the closest feature parity with Quzo here. It has a limited free plan and paid plans from $35/mo. A solid choice if you want an established name with proctoring.
- Best for: schools and businesses wanting a proven exam tool with proctoring.
- Limited free, paid from $35/mo.
3. ProProfs: best for training programs
ProProfs pairs quiz/exam creation with AI generation, auto-grading, and reporting, priced per active test-taker. Its anti-cheating settings help but stop short of full webcam proctoring, so it fits training and internal assessments more than high-stakes proctored exams.
- Best for: corporate training and internal certification.
- Free for small quizzes, $19.99 per 100 takers/mo.
4. Testmoz: best budget pick
Testmoz is deliberately simple: build a test, set the answers, share a link, and it grades automatically. Its paid plan is just $50 a year, the cheapest here, but there's no AI generation and no proctoring, so it's for low-stakes, no-frills testing.
- Best for: simple, low-cost tests without security needs.
- Free (50 Q / 100 results per test), $50/year (Hero).
5. Exam.net: best for secure school exams
Exam.net is purpose-built for secure school examinations, with strong lockdown and exam-security features and math support. It's quote-based (a yearly per-school license) with no free plan beyond a trial, so it suits institutions rather than individuals.
- Best for: schools running secure, invigilated exams.
- Trial only, custom yearly pricing.
6. ClassMarker: best for high-volume testing
ClassMarker is a long-established online testing platform with AI question generation, strong test-security settings, and auto-grading. Pricing scales by test-taker volume (billed annually), making it a fit for certification bodies and high-volume programs.
- Best for: certification and high-volume testing programs.
- Trial only, volume-based annual pricing.
7. Google Forms: best free basic option
If your exams are low-stakes and you just need something free, Google Forms' quiz mode auto-grades multiple-choice and short answers and shares instantly. There's no AI generation, no question bank, and no proctoring, but for quick classroom checks it's free and everywhere.
- Best for: free, low-stakes classroom quizzes.
- Free.
