ChapterGen vs DriftNote

ChapterGen generates YouTube chapters from uploaded video or audio files. It transcribes the audio, detects topic shifts, identifies sections, and creates chapter titles. Because it works from uploads, creators can prepare chapters for unpublished, private, or unlisted videos without providing a public YouTube URL. Audio-only material such as podcasts, interviews, and voice recordings is supported. Users can edit titles and timestamps before copying the output, which starts at 0:00 and is formatted for a YouTube video description. The FAQ lists MP4, MOV, AVI, WebM, MKV, MP3, WAV, M4A, AAC, OGG, and FLAC, with a maximum file size of 500 MB. The site's Whisper-based AI auto-detects language and supports 90+ languages. The homepage says uploads are deleted automatically after processing. The Free plan costs nothing and allows 2 videos of up to 20 minutes each, with no signup. Paid one-time plans are $5, paid once for 5 videos and $12, paid once for 15 videos. ChapterGen is a web tool.

DriftNote turns podcast episodes into summaries for listeners and production materials for creators. Listeners can submit Spotify, Apple Podcasts, YouTube, or RSS links for summaries with topics, quotes, and timestamps. They can follow podcasts to receive automatic summaries of new episodes; the Free plan allows one followed podcast and five summaries per month. Summaries can sync to Notion, be shared through public links, or posted to X or LinkedIn. DriftNote also connects to Claude, ChatGPT, Meta Muse, and other assistants that support connectors, and offers a REST API with keys available in Settings. The listener workflow runs through the website without installation or a browser extension. For producers, Producer Studio accepts MP3, MP4, M4A, and WAV files. Producer Pro creates full transcripts, show notes, timestamped chapters, five title options, and key quotes, and can learn a style profile from existing episodes. AI processing on all plans uses Google Gemini. Free is free; Pro is $9.99 a month, billed monthly. Producer Pro is $24 a month, billed monthly after a 7-day free trial.
