Local media in · caption file out

Caption files without the upload queue.

Polley Word By Word SRT turns audio and video stored on your Windows computer into detailed SRT files. Your source material stays local, so private drafts, client interviews, and unpublished episodes do not have to be sent to a browser service.

A caption workflow built around files you already own.

01 / Keep footage private

Process recordings on your own Windows machine instead of transferring the full media file to an online caption portal.

02 / Preserve word timing

Generate an SRT with word-level cues ready to bring into an editor, caption tool, or downstream styling workflow.

03 / Queue more than one

Use batch processing when a project contains multiple interviews, lessons, clips, or episode files.

From recording to portable subtitles.

LOCAL

Useful for unreleased and sensitive recordings.

Local processing is a practical choice when a creator is working under an NDA, preparing an unreleased course, captioning client footage, or simply avoiding a slow upload. The app produces the caption file on the same computer that holds the media.
