Caption draft

AI tools turn your transcript into captions, summaries, hooks, and more—grounded in the exact words from your video.

A caption generator can turn a finished transcript into social copy, hooks, rewrites, and brief-style notes based on what was actually said in the video. With VidiRelay, you start from transcript text you can review and edit before publishing, which helps you check facts, tone, and fit for each channel.

How it works

The page job starts after transcript work is already completed.

  1. 1

    Open a completed transcript

    Start with saved transcript text from a public link source or an uploaded file you already processed. Review the wording and timestamps so the source is ready for writing tasks.

  2. 2

    Choose the writing action you need

    Generate captions, hooks, summaries, rewrites, brief-style notes, or analysis from the transcript. The result gives you a draft tied to the source material instead of a blank starting point.

  3. 3

    Review and publish with edits

    Check the generated text for facts, tone, and publishing rights before using it. Then copy or export the transcript and related materials in the format that fits your workflow.

Why use a transcript-based caption generator

Starting with the spoken source changes the writing job in useful ways.

Works from completed transcript text
This tool is built for writing after transcription, not for guessing what a video might contain. That makes it useful when you need captions or script variations grounded in the actual spoken content.
Supports common transcript export formats
Completed transcripts can be reviewed with timestamps and exported as TXT, SRT, VTT, CSV, JSON, and DOCX-ready text. That gives editors and content teams options for handoff, archiving, and publishing prep.
Fits public links and uploaded media
You can begin with one public link, up to 50 links in a batch, a supported public collection, or an uploaded audio or video file. Supported public link sources include TikTok, Instagram, YouTube, and Facebook.

What to keep in mind

A few limits are worth knowing before you rely on generated copy for publishing.

  • A source may fail if the video is private, requires login, has been removed, is region-blocked, or is otherwise unavailable.
  • Generated captions and rewrites should be reviewed for factual wording, brand tone, and rights before publication.
  • If a source will not process, use an uploaded audio or video file you have permission to work with, or switch to another public source.

AI Tools FAQ

Caption Generator FAQ

Can I use this caption generator for short-form social posts from a video transcript?

Yes. It can draft caption-style copy, hooks, and rewrites from completed transcript text, which is useful for short-form social publishing and repurposing.

Do I need to start from a blank script or writing box?

No. Content actions start from transcript text, so you are working from the words already captured from the video rather than starting from scratch.

Can it use private or login-only videos?

No. It should not be used as if it can access private or login-gated videos, and some public sources may still fail if they are unavailable or blocked.

What should I check before I publish generated captions?

Review the transcript and the drafted text for facts, tone, and any rights concerns tied to the source material. You should edit the transcript and generated copy before publishing.
