AutoSubSync – automatic subtitle synchronization tool

AutoSubSync is a user-friendly tool that automatically synchronizes your subtitles with your videos using powerful tools such as ffsubsync, autosubsync and alass. It also lets you manually adjust the subtitle timings. Just drag and drop your files, and let AutoSubSync do the rest, making subtitle alignment both simple and efficient.

This is cross-platform software which runs under Linux, macOS, and Windows.

AutoSubSync is free and open source.
