About Plain text (.txt) files

A plain-text transcript is what you want for blog posts, show notes, accessibility documents, or feeding text into a search index or language model. CaptionStack strips all timing and writes each cue as its own paragraph. Importing a .txt file assigns three-second cues so you can add real timing in the editor.

Where .txt is used

  • Blog posts, show notes, and documentation
  • Search indexing and AI summarization
  • Accessibility transcripts

What a .txt file looks like

Caption files, meet your new converter.

Everything happens privately in your browser.

What converts and what doesn’t

Exporting to TXT intentionally drops timing and identifiers. Importing TXT creates evenly spaced three-second cues.
