ChapterGen turns uploaded audio or video into YouTube chapters. It transcribes the recording, detects topic shifts, identifies sections, and drafts descriptive titles with timestamps. You can edit both before copying; the output begins at 0:00 and is formatted for a video description. Uploading means you can prepare chapters for unpublished, private, or unlisted videos without a public YouTube URL. ChapterGen also accepts audio-only content such as podcasts, interviews, and voice recordings. Its Whisper-based AI auto-detects language and the site lists support for 90+ languages. The FAQ names MP4, MOV, AVI, WebM, MKV, MP3, WAV, M4A, AAC, OGG, and FLAC, with a 500 MB maximum file size. The homepage upload prompt lists a smaller set of formats. Uploaded files are automatically deleted after processing, according to the homepage. ChapterGen runs on the web. The free plan allows 2 videos up to 20 minutes each with no signup; one-time plans cost 5.00 USD per once for 5 videos or 12.00 USD per once for 15 videos.
