ExamClip: Turn lecture videos into searchable handouts

Convert dozens of online course videos into searchable, printable chapter handouts for exam prep

Problem

When prepping for exams, going back to a specific concept from a 40-lecture course means scrubbing by memory; videos can't be searched or printed, making review painfully inefficient.

Solution

Users import course videos; the tool runs scene detection to capture key frames, pairs them with local speech-to-text subtitles, and lays out an A4 landscape handout with one key frame and its subtitles per page; text is searchable and copyable, and links back to the original video timestamp.

Users

Exam prep students who need to repeatedly review online course videos for grad school, certification, or professional exams

MVP

Batch import videos; ffmpeg scene detection for key frames; local Whisper transcription with proofreading; generate timestamped A4 PDF; keyword search jumps to video timecodes

Revenue

Free tier limits total video length; paid unlocks batch processing and term dictionary packs; sell prebuilt terminology packs for specific exams

Why now

Local Whisper and scene detection are mature enough to run on ordinary computers; online course consumption keeps growing and users urgently need to convert videos into searchable study material
