# Write the post captions for Instagram, LinkedIn and X Canonical URL: https://viditor.app/prompts/write-post-captions-for-each-platform Last updated: 2026-10-13 > TL;DR: Type "Write the post captions for Instagram, LinkedIn and X" and Viditor reads what your finished video says, finds its one idea and strongest line, and replies in chat with a separate caption for each platform, within its length limit. You copy the ones you like and paste them when you upload the video yourself. ## What to say > Write the post captions for Instagram, LinkedIn and X Category: Publishing ## What Viditor does 1. Reads what the edited video says and its on-screen titles, not just your first idea. 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 the style preferences you've asked it to remember, such as tone, emoji and hashtags. 5. Replies in chat 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, right in the chat where you edited it. ## What does Viditor do when you say this? Viditor 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. The reply lists every caption with its character count, ready to copy. It writes from the cut, not from your first idea, 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 Viditor 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 a draft in chat 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. Then open **Exports**, show the file in Finder, and upload it with the caption in the platform's app or the scheduler you already use. Viditor doesn't post for you. ## Honest limits - Captions come back as chat text. Nothing is saved as a post draft or sent to any platform. - 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 you haven't edited the video yet, ask after the edit, so a section you removed doesn't end up in the caption. ### Does Viditor post or schedule the captions? No. The captions arrive as a chat reply for you to copy. Viditor doesn't save post drafts, post or schedule anything. Upload the export from the Exports tab and paste the caption in the platform's app or your own scheduling tool. ## Related - [How do I export a video from Viditor?](https://viditor.app/docs/export) - [Video hook](https://viditor.app/glossary/video-hook) - [How to repurpose one video for every platform](https://viditor.app/blog/repurpose-one-video-for-every-platform) - [Review it before I export](https://viditor.app/prompts/review-it-before-i-export) Download Viditor for Mac (one-time licence, see https://viditor.app/pricing): https://viditor.app/download
