Editing Captions Per Platform

Editing captions per platform (and solving character limits)


When you create one post and publish it to multiple channels, character limits, formatting, and tone all differ. Mavic lets you tailor the caption for each channel from a single post.


Why captions need to be different


Platform

Character limit

Style

X (Twitter)

280 (free) / longer for paid

Punchy, single-idea, hashtags optional

Threads

500

Conversational, light formatting

Bluesky

300

Punchy

LinkedIn

3,000

Long-form okay, no emojis-first openings

Facebook

63,206 (but ~80 chars before "see more")

Conversational, community-driven

Instagram

2,200

Visual-first; caption supports the image

TikTok

2,200 (caption); script length is what matters

Hook in 3 seconds; trend-aware


A caption optimised for LinkedIn will look bloated on X. A caption optimised for X will feel thin on LinkedIn.


How to edit per platform


After Mavic generates a multi-channel post:


  1. Open the post in the editor (it'll show channel tabs at the top — Instagram, LinkedIn, X, etc.).
  2. Click each channel tab.
  3. Edit the caption specifically for that platform.
  4. Save when done.


Mavic shows the character count in real time. It also flags hashtags, mentions, and links that platform-specific rules apply to.


Asking Mavic to do the edit for you


Instead of editing manually, you can ask Mavic:


"Tighten the X version to 250 characters and lead with the strongest hook."

>

"Expand the LinkedIn version to ~1,200 characters. Add a personal anecdote in the second paragraph and end with a question."


Mavic edits in place. Refine again if needed.


Solving character limit issues


If a generated post is too long for a platform:


  • Switch to that platform's tab and edit down
  • Ask Mavic to summarize"Summarize this for X in under 280 characters."
  • Remove low-value text — repeated CTAs, redundant emojis, link-shortened URLs
  • Use thread-style formatting for X if the idea genuinely needs more space (a thread of 2–3 posts beats one over-stuffed post)


Hashtags


Hashtag etiquette varies:


  • Instagram — 5–15 hashtags, mix of broad and niche
  • LinkedIn — 3–5 max, mostly industry-specific
  • X — 1–2 max
  • Facebook — 1–2 max
  • TikTok — 3–5, including trending tags
  • Threads / Bluesky — sparingly


Ask Mavic: "Suggest hashtags for this post on Instagram" and it'll generate platform-appropriate ones.



Most social platforms don't make links clickable in the caption. Workarounds:


  • Instagram — put the link in your bio and write "link in bio"
  • LinkedIn — put the link in the first comment for better reach (some debate on this; test for your account)
  • X — links are fine in the caption
  • TikTok — link in bio; for some accounts, inline links


Mavic respects each platform's link conventions automatically.


Saving the multi-channel post


When you've tailored each tab, click Add to Planner or Publish. Each channel gets its own scheduled post with the channel-specific caption.
