Subtitles need timestamps; forced alignment makes them. Drop in any audio you have a transcript for, align it on-device, and export a ready-to-use SRT block — the exact format video players and editors consume. Audio never leaves your machine.

Bundled JFK sample: inaugural address excerpt (20 January 1961), spoken by John F. Kennedy — public domain, U.S. government work. JFK audio source and attribution record.
SRT output (one caption per word — group them in your editor)
The SRT uses word-level captions so you can see the raw timings; most editors can merge them into sentence cues. Try it with your own recording and its transcript — the aligner only needs the words to match the audio.
