Speech, not social post text
The input is a video file containing spoken audio. The output follows that speech. This is not a tool for writing Instagram descriptions, hashtags or LinkedIn post copy.
AUTOMATIC CAPTIONS
Automatic captions from the speech in your video
Capgen transcribes the audio in an uploaded video and places words on a timeline. Preview those captions with your footage, choose a readable style, then export a captioned video or download an SRT subtitle file.
AUTOMATIC CAPTIONS
What automatic captioning does and does not do
Word-level timing
Timed words let a highlight follow the speaker. Listen to the preview at the original speaking pace: a phrase that looks clear while paused may be too dense during playback.
Review before publishing
Background music, overlapping speakers, accents and unfamiliar names can produce transcription errors. Check quotations, numbers and names against the recording. Automatic output is a draft, not a guarantee of accuracy.
Choose the right export
A video export contains the visible caption styling. SRT is a separate plain-text file with cue times; it does not carry font choices, highlight colors or animation. Keep the original recording as your source.
IN THE STUDIO
Generate captions from an uploaded clip
- Sign in, open the studio and upload a prepared video. New free accounts have five video credits and a 100 MB upload limit. Select the language spoken in the recording.
- Generate the captions and play the preview with audio. If the recording is unclear, improve the source audio and regenerate rather than treating an uncertain quotation as verified.
- Choose a font, words-at-a-time setting and caption position. Export the captioned video or download SRT, then check the downloaded file before sharing.

Questions about automatic captions
Does automatic captioning require a public video URL?
No. The studio takes a file from your device. It does not download videos from a YouTube, Instagram or TikTok link.
Can I upload an audio-only recording?
This workflow expects video. Combine an audio-only recording with a visual in another editor before uploading it to Capgen.
Does Capgen translate the captions?
Choose the spoken language for transcription. This workflow does not promise translation into a different language.
