> TL;DR: Type "Write the post captions for Instagram, LinkedIn and X" and Vidiyo reads what your finished video says, finds its one idea and strongest line, and writes a separate caption for each platform within its length limit. It saves them as drafts on the video's posts and replies with each caption and its character count.

## What Vidiyo does

1. Reads what the edited video says and its on-screen titles, not just the original brief.
2. Finds the one idea and the strongest concrete line to use as the hook.
3. Writes a separate caption for each platform, in its style and within its length limit.
4. Follows your saved preferences for tone, emoji and hashtags.
5. Saves each caption as a draft on that platform's post, without scheduling anything.
6. Replies with every caption and its character count, and notes anything it guessed.

Writing three versions of the same post is the part of publishing most people skip, so one caption gets pasted everywhere. This prompt writes a proper caption for each platform from what your video actually says.

## What does Vidiyo do when you say this?

Vidiyo reads what your edited video says and shows, finds its one idea and its strongest concrete line, and writes a separate caption for each platform. The strongest line becomes the hook everywhere, sharpened for each. Captions are saved as drafts on the video's posts, and the reply shows each one with its character count.

It writes from the cut, not from the original brief, so a section you removed doesn't sneak back into the caption. Each platform gets its own shape: a hook that reads before "more" on Instagram, a short line under 280 characters on X, short paragraphs with a real question at the end on LinkedIn, a searchable title for YouTube Shorts. No "In this video", no generic hashtags.

## How do you phrase it?

Name the platforms, and add tone or rules if you have them:

- "Write the post captions for Instagram, LinkedIn and X"
- "Write a YouTube Shorts title and description"
- "LinkedIn caption, first person, no emoji"
- "Instagram caption ending with 'comment GUIDE for the link'"
- "Shorter, and drop the hashtags"

When you correct the style twice, like "no emoji", ask Vidiyo to remember it, and future captions follow it.

## How would you do this by hand?

By hand, you'd rewatch the video, pull out the main point, write a caption, then rewrite it for each platform's length and tone, count characters for X, and pick hashtags. It's not hard, but it comes at the end of a long edit when you're least in the mood for it. Here you edit drafts instead of starting from a blank box.

## What should you check afterwards?

Read every caption for voice. The assistant reuses your phrasing from the video, but you know how you sound. Check numbers and names against the video, and any call to action against what you actually want people to do. When they're right, ask Vidiyo to schedule them.

## Honest limits

- Captions are written in the language of the video's transcript. Hinglish videos may need words fixed, since Hindi transcribes in Devanagari.

## Frequently asked questions

### Does it write the same caption for every platform?

No. Each platform gets its own copy: a hook line and a few short lines for Instagram, one or two punchy sentences under 280 characters for X, short paragraphs for LinkedIn, and a searchable title plus description for YouTube Shorts.

### Will it make up claims the video doesn't make?

It writes only from what the cut says and shows on screen. If the video has no edit yet, it drafts from the script and marks the captions as provisional.

### Does writing captions schedule the posts?

No. Captions are saved as drafts. Scheduling is a separate request, so you can review and edit first.
