Auto subtitle loading for JAV video sites

Subtitles for JAV videos, loaded instantly.

SubPilot reads the code on the video page, finds a matching subtitle file, and loads it into your player — with full sync, styling, and playback speed control. No manual downloads, renaming, or copy-pasting.

Speed control and manual SRT upload are free. Automatic subtitle search requires an account.

FAQ

Common questions

Does SubPilot host any video content?+

No. SubPilot is a subtitle enhancement tool only. It loads and displays subtitles; it does not host, upload, or promote any video content.

Is the speed controller free?+

Yes. Playback speed control and manual SRT/VTT/ASS upload are completely free and work without an account.

How does automatic subtitle loading work?+

When you open a video page, SubPilot detects the movie code and queries a subtitle source through our backend to fetch a matching subtitle file. Automatic subtitle search requires a signed-in account.

Can I adjust subtitle timing?+

Yes. Use the sync controls to nudge timing forward or back in 100ms increments until the track is aligned.

Stop matching subtitles by hand.

Install SubPilot and let it find, load, sync, and style subtitles for you — while you control the speed.
