Live demo

A direct flow from setup to readable captions to translated PiP.

The product story is simple when the interface is shown in order: pick the language, start the live transcription, then switch into translation the moment another language is needed.

Capti live transcription setup screen
01 Set up

Choose the language and start the screen-audio session.

The first screen keeps the workflow light. Pick the language you want to follow, begin the broadcast, and move straight into live captioning without a heavy setup ritual.

  • Start from a focused setup screen instead of a dense utility interface.
  • Prepare the app for the language you want before the live audio begins.
  • Keep the workflow fast enough for a class, meeting, or livestream that is already in progress.

02 Caption live

Follow the spoken words as the transcript grows on screen.

Capti keeps the language readable while the main content continues. That makes it useful for fast-moving video, recorded talks, calls, and any spoken content where missing a sentence breaks the rest of the experience.

  • Read the words while the original content keeps playing.
  • Use a subtitle-style layout that stays easy to scan quickly.
  • Keep comprehension high when the speaker moves too fast or the audio is hard to catch.

03 Translate

Switch the PiP captions into another language the moment you need it.

Translation stays part of the same live flow instead of feeling like a separate export step. Capti can keep the original speech understandable for viewers who need a different language right now.

  • Instant translation is available in 20 supported languages.
  • The floating PiP window keeps captions readable without taking over the full screen.
  • Language switching works for the same live content across videos, classes, calls, and streams.

Reopen the conversation later with timestamps and translated archives.

Capti Pro keeps more than the live moment. Save transcripts with timestamps, reopen them later, and read the original text beside translated versions when you need to study, review, or reference what was said.

  • Save transcripts so important spoken content does not disappear with the live session.
  • Review the original transcript alongside translated text in the same archive flow.
  • Use the saved view as a readable history for classes, meetings, calls, and long-form videos.
File demo

Import recorded video, transcribe it, and export subtitles as .srt.

When the content is not live, Capti Pro still keeps the workflow direct. Bring in recorded video, generate the transcript, then export subtitle files for reuse in editing, publishing, or reference workflows.

Video import Transcribe recorded video instead of only whatever is playing live on the screen.
.srt export Turn the transcript into subtitle files that are easy to reuse elsewhere.
Timestamps Keep the transcript aligned to the source so later review and editing stay practical.
Simple workflow Import, transcribe, review, and export without sending people through a complicated production tool.
