TestForge — AI Test Builder

Turn any AI chat into interactive, auto-graded practice tests. No scraping, no API keys — just copy and paste.

TestForge turns any AI chat into an interactive practice test you can actually sit and take. You already have a chat full of your syllabus — lecture notes you pasted, a textbook chapter you worked through, a topic you spent an hour arguing with the AI about. That context is the most valuable study material you own, and it's stuck in a scrollback. TestForge gets it out. HOW IT WORKS 1. Build — Enter your subject, the topics you want covered, and how many questions of each type you need. 2. Copy — TestForge writes a precise prompt for you. 3. Paste it into your own AI chat — ChatGPT, Claude, Gemini, whichever one already knows your material. The AI replies with your test as structured data. 4. Paste that back into TestForge. It validates the test, renders it, and you take it. Your results, your score breakdown, and your full attempt history stay in the extension. SIX QUESTION TYPES Multiple choice · True/false · Short answer · Long answer · Fill in the blank · Match the following INSTANT GRADING, NO TOKENS SPENT Objective questions grade on exact match. Written answers grade against key concepts — with synonyms and weightings — that the AI works out when it builds the test, so scoring happens the moment you hit submit. You can set it strict, partial, or lenient depending on whether you're drilling definitions or checking that you understood the idea. Grading never calls an AI. It costs you nothing and works with your Wi-Fi off. BUILT TO STAY OUT OF YOUR WAY TestForge opens as a panel docked to the side of whatever page you're already on. Click the toolbar icon to open it, click again to close it. Your test travels with you. PRIVACY, PLAINLY TestForge makes no network requests. None. Not for fonts, not for analytics, not for grading. It never reads, scrapes, or modifies the page you're on — it only draws its own panel. There is no account, no sign-up, and no server. Everything you build stays in your browser's local storage on your own machine. The copy-paste handoff isn't a limitation we haven't gotten around to. It's the design. It keeps TestForge off your AI account, works with every chat platform equally, and means there's nothing for us to collect. WHO IT'S FOR Students revising for exams, anyone preparing for a certification, and self-learners who've realised that re-reading notes feels like studying and testing yourself actually is.
