Windows subtitle utility

Give every word its moment.

Polley Word By Word SRT creates detailed subtitle timing from your local audio or video. Generate a portable SRT on Windows, then take it into your editor to build readable captions, emphasized words, or kinetic text.

Sentence captions tell viewers what was said. Word timing tells an editor when it was said.

That extra timing detail is useful when individual words need to appear, highlight, or move in rhythm with speech. The SRT remains a standard text-based subtitle file, so you can inspect it and carry it into another application rather than locking the result inside an online service.

Where it fits

A timing foundation for several caption styles.

◉

Short-form emphasis

Use individual cue timing as a starting point for captions that emphasize the current spoken word.

⌁

Dialogue alignment

Match text more closely to the pace of interviews, explainers, tutorials, and narrated videos.

↗

Editor handoff

Generate the timing file first, then handle typography, animation, and final review in your chosen editor.

Simple handoff

Generate locally. Style intentionally.

STEP 01

Choose source media

Select a recording from your Windows computer. Audio and video can both serve as the speech source.

STEP 02

Create word-timed SRT

The desktop app transcribes speech and writes detailed subtitle cues without requiring a browser upload.

STEP 03

Review and import

Check the text, then bring the SRT into the editing or caption application that completes your visual treatment.

Need privacy more than animation?
