Platform Capabilities
Everything you need
to practice smarter.
Turn any topic, PDF, or YouTube video into a full exam-pattern mock test — graded instantly, reviewed in detail, and tracked over time.
Three Ways To Start
Generate a test from whatever you already have
No retyping notes or building question banks by hand — pick a source and let Tiny AI do the rest.
Topic / Text
Type any subject — CUET General Test, Indian Polity, Cell Division, Banking Awareness — and get a full set of exam-style MCQs in seconds. Paste extra notes or a syllabus for sharper, more relevant questions.
PDF Upload
Drop in a text-based PDF up to 3 MB. ThunderStudy AI extracts up to roughly 4,000 words of content automatically and uses it as the source material for your test.
YouTube Video
Paste a YouTube link, fetch the video's transcript with one click, and generate a mock test built entirely from what was actually said in the video.
Exam Experience
A real exam-pattern interface
Not a quiz widget — a full CBT-style test environment built to match what you'll actually sit for on exam day.
Timed CBT Interface
A countdown timer, question-by-question navigation, and an NTA-style layout so the format feels familiar long before exam day.
Question Palette & Review
Jump to any question instantly, mark questions for review, and see your answered / unanswered / marked status at a glance.
Instant Results & PDF Report
Get your score the moment you submit, review every question with the correct answer explained, and download the whole result as a PDF.
