A first comment is a comment posted under your post once it's live. It's handy for links, extra hashtags or a question for your viewers.

Add one

  1. On the Text step of posting, type it in First comment (optional).

  2. Read the line under the box. It shows which networks get a comment and which don't.

  3. On the Check and send step, check the First comment row for each network.

How each network handles it

  • Instagram, Facebook, LinkedIn and Threads: posted as a comment once the post is live. X too, when it's available.
  • YouTube: YouTube has no first comments, so it's added to the end of the description. If you wrote your own YouTube description, it isn't added.
  • TikTok: TikTok has no first comments. To keep it, tick Add first comment to the caption on TikTok. The caption and the comment then share TikTok's 2,200 characters.
  • Reddit: not supported.

Each network's caption limit also applies to the first comment. For example, on Threads it can be up to 500 characters.

If a first comment fails

After you post, each account's row on the video's page shows the first comment's status, such as posted, in the description or failed. ReShare AI waits a minute after the post goes live, then tries up to 3 times before giving up.

Add a first comment

When a first comment fails, you can:

  • Tap Copy comment, then paste it under the post yourself.
  • Tap Open post to open the post on the network.
  • Tap Retry, when it's offered.

If the network didn't confirm the comment, check the post before you retry, so you don't post it twice.
