ChapterGen vs Deciphr

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 Because it works from uploads, creators can prepare chapters for unpublished, private, or unlisted videos without providing a public YouTube URL.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.

Deciphr turns audio, video or document files into content such as transcripts, show notes, summaries, articles, social captions, tweet threads, quotes and chapter timestamps. It is intended for podcasters, webinar hosts and video creators. Users can upload files in batches from a YouTube channel, playlist or RSS feed, and an interactive library can answer questions about files and folders, generate ideas, summarize files and organize the library by subject. An in-app editor lets users customize articles, audiograms and video reels. Professional and Enterprise subscribers receive audiograms and video reels in their content suite. Deciphr says it can generate a complete suite from an audio file in less than seven minutes. Files and generated content are private by default unless shared, and supported files and generated content are currently limited to US English. The free Flexi Free plan offers text-only content for up to 40 minutes. Paid plan details include Hobbyist at $29/month and Professional at $69/month; the listed pricing note says paid access starts at $24/month, billed annually.
