VideoChapter: AI Chapters

Turn long videos into a searchable workspace on your Mac.

VideoChapter uses private on-device AI to generate chapters, summaries, transcripts, speaker labels, and grounded answers from local video files. Review moments faster, jump to exact lines, translate transcripts, and export clean outputs for YouTube, subtitles, notes, and edits — without uploading your video for core processing after models are installed.

Features:
• Automatic chapters with timestamps and summaries
• Searchable, time-aligned transcripts
• Click any chapter or transcript line to jump the player
• Ask questions about the video and open exact moments
• Translate transcripts into supported system languages
• Export chapters as YouTube, Markdown, CSV, and JSON
• Export transcripts as SRT, VTT, Text, and JSON
• Export shortened videos using selected chapters
• Reopen processed videos faster with local caching

Built for creators, educators, researchers, and anyone who works with long-form video on macOS.

Advanced features such as Assistant and export may require Pro. Transcript translation depends on installed Apple translation support.
