ChapterGen vs KondensMe

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 Because it works from uploads, creators can prepare chapters for unpublished, private, or unlisted videos without providing a public YouTube URL.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

KondensMe is a web app that turns videos, podcasts, and documents into structured AI analysis. Reports combine summaries, actionable points, and open questions, with interactive mindmaps built from clickable nodes. For videos, Golden Clips connect key points to exact source timestamps. Searchable transcripts include speaker detection and timestamps, and summaries can be translated into over 15 languages on demand. Listed inputs include YouTube videos and Shorts, podcast audio files, PDFs, and DOCX documents. Analyses can be exported as PDF, HTML, Markdown, X Articles, or presentation slides; generated presentations can also be exported as PPTX and PDF. Reports can be organized into folders and searched with AI across a knowledge library. Users can subscribe to YouTube channels or podcast RSS feeds for automatic episode processing. A bot can join Google Meet calls and produce a recap with action items, decisions, and a follow-up email. Free accounts require sign-up and show five AI chat messages per session; premium plans are available for heavier usage, with prices and usage counts unspecified.
