Windows app that turns Douyin videos you're authorized to access into a searchable local knowledge base.

Desktopfree

TokBrain is a Windows app that turns Douyin videos a user pastes in — and is authorized to process — into a local, searchable knowledge base. It checks each video's stated download permission, extracts subtitles, keyframes, and an AI summary, and supports source-cited question answering plus export to Obsidian. It's designed for individuals who want to reuse knowledge from short videos rather than just rewatching saved clips, with built-in rate limits and permission checks.
