About SubFlow
SubFlow helps YouTube creators reach a global audience by automatically translating video titles, descriptions and subtitles, and publishing them straight to your channel.
✦ Translate titles & descriptions into 31 languages (Spanish, Japanese, Korean, Hindi, Arabic, French, German, Portuguese, and more)
✦ Upload subtitle tracks based on YouTube's machine-translated captions — published as real tracks your viewers can switch on
✦ Works with videos in any language — the source language is detected automatically (no longer English-only)
✦ Safe to re-run — always translates from your original title and source track, and replaces old translations instead of duplicating them
✦ NEW: Delete mode — clean up translated subtitle tracks and localized titles you no longer want
✦ NEW: Cancel anytime, and resume — close the panel mid-run and progress picks right back up when you reopen it
✦ Dark mode + English & Chinese (简体中文) interface
✦ Multiple channels and Brand Accounts supported
✦ One-click workflow — paste a URL, hit Start, done
✦ Secure Google OAuth via PKCE — no passwords, tokens never leave your browser
Requirements:
- To translate subtitles, your video needs a caption track in its original language (any language works)
- Title & description translation works on any video, no captions needed
Free: 3 runs per day, each covering all 31 languages of one video. No signup required.
