Privacy-first
Your video never leaves your Mac
Most tools require uploads. VideoChapter doesn't. Core processing runs entirely on-device, prioritizing your privacy.
Core processing happens on your Mac after a one-time model download (~8 GB). No remote processing required.
You can use the app without creating a VideoChapter account or signing into a web service.
Source videos, transcripts, chapters, summaries, and assistant answers stay on your Mac for core workflows.
Internet access may still be used for model downloads, purchase flows, updates, or optional anonymous analytics.

FAQs
Frequently Asked Questions
Does VideoChapter really work offline?
Core processing runs locally after the one-time model download. Network access may still be used for downloads, updates, purchase checks, or optional anonymous analytics.
What video formats are supported?
VideoChapter is designed around common formats macOS media frameworks can open reliably, including MP4, MOV, and M4V. Results can vary with unusual codecs or damaged files.
How accurate is the transcription?
Accuracy depends on audio quality, speaker overlap, and language support. For clear speech, the output is typically strong enough to search, skim, and export, but you should review anything you plan to publish.
What Mac do I need?
macOS 26 or later. Apple Silicon is recommended for best performance.
Is there a subscription?
No. The Free tier is free forever. Pro is a one-time purchase of $59.99 — no subscription, no recurring charges.
Can I try before buying Pro?
Yes. The Free tier covers chapters, transcript, and search so you can evaluate the core workflow before unlocking assistant, translation, and export features.
