Jared JamesYes on Instagram and no on TikTok: a scheduler that publishes through Instagram's official API can post your first comment seconds after the post goes live, on feed posts and Reels from a professional account, while TikTok gives tools no way to create a comment at all, so on TikTok the first comment always comes from you, by hand, after the video publishes.
It helps to be precise about what the feature is, because no platform has scheduled comments. What actually happens is that the tool publishes your post through the platform's API, and the moment the platform confirms the post is live, the tool makes a second call that posts your comment from your account. So the feature is automation at the instant of publishing, and the whole thing depends on whether the platform's API lets an app post a comment. Instagram's does. Facebook's does. LinkedIn's does, for tools that have been approved for it. TikTok's does not, and that single difference drives everything below.
The manual route is free and described below. On TikTok, no tool can do the job at all.
How a Scheduled First Comment Actually Posts
On Instagram the requirements are the same as for scheduling itself: a professional account, Business or Creator, connected to the tool, because Instagram's publishing API does not serve personal accounts. You write the comment in the composer next to the caption, the post publishes at its scheduled time, and the tool posts the comment straight after, usually within a few seconds. It works for feed posts, carousels, and Reels, and it can never work for Stories, because Stories have no comments. The comment posts from your own account through the same official API the post used, so the reach worry that follows this feature around has nothing to feed on; whether scheduling costs reach at all has its own page, does scheduling hurt Instagram reach.
One difference separates careful tools from careless ones: the comment is a second, separate API call, and once in a while Instagram accepts the post and then rejects or delays the comment. The right behavior is what you would do by hand, the post stays up and the comment failure gets logged for you to retry, rather than the whole post being treated as failed. Maeve works that way. Check which way your tool falls before a launch post is on the line.
Maeve Composer
A first comment field sits beside the caption for Instagram, Facebook, and LinkedIn posts. Saved hashtag groups drop into it, it rides through approval with the rest of the post, and it publishes on its own seconds after the post goes live.

What the First Comment Is For Now
For years the feature's famous job was moving a wall of hashtags out of the caption. Instagram has changed hashtag limits and recommendations over time, so check the current composer and creator guidance instead of treating an old fixed count as strategy.
The first comment is also useful for a translation, credits, sources, or extra context. One habit does not transfer from LinkedIn: links in Instagram comments are not tappable. Use the bio or an Instagram Story link sticker for a clickable destination.
On TikTok Nobody Can Do It, So Here Is the Workaround
TikTok's Content Posting API, the official route every legitimate scheduler publishes through, has no endpoint for creating a comment. The only comment control it offers a tool is a toggle at posting time for whether comments are allowed on the video at all. So a scheduler can publish your TikTok on time but cannot put a comment under it, and a tool claiming to auto-post TikTok first comments is worth interrogating about how, because whatever it is doing, it is not using the official API. The wider story of what TikTok automation is allowed to do is the same story: the API decides.
The workaround is manual: schedule the video, confirm it is live, then post the comment from TikTok. Pinning availability can vary by account and app version, so do not make the workflow depend on it. If the first comment is essential, choose a publish time when someone can add it.
Platform by Platform, Including LinkedIn
Links in LinkedIn comments are clickable, but LinkedIn does not document a universal reach advantage for keeping a link out of the post body. Comment publishing depends on the scheduler's LinkedIn permissions and implementation, so verify the exact feature rather than assuming a LinkedIn logo includes it.
In Maeve the first comment is a field in the composer for Instagram, Facebook, and LinkedIn posts, saved hashtag groups drop into it the same way they drop into captions, and it goes through client approval attached to its post rather than as a loose end. On X and Threads the same job has a different shape: the follow-up is scheduled as a reply in a thread, up to twenty messages deep. TikTok has no first comment field in Maeve because TikTok gives tools no way to post one, and we would rather the field be missing than quietly fail.
| Platform | Can a tool post it? | The detail |
|---|---|---|
| Yes | Feed posts, carousels, and Reels on a professional account. Never Stories, because Stories have no comments. | |
| Yes | Page posts through the official API. Personal profiles do not connect to schedulers in the first place. | |
| Yes, in some tools | The tool needs LinkedIn's Community Management API approval, so check the specific feature per platform, not the logo row. | |
| TikTok | No | The Content Posting API has no comment-creation field. Add the comment in TikTok after the video is live. |
| X and Threads | As a thread | Some tools can schedule a reply chain. This creates a thread, not a separate first-comment feature. |
The Free Answer
There is no free native route. The Instagram app, Meta Business Suite, and TikTok's built-in scheduler have no first comment field, and third-party schedulers almost always keep the feature on paid tiers. The genuinely free version is you: schedule the post with whatever free tool you already use, catch the publish notification, and paste the comment in yourself. It costs nothing except the exact thing the feature exists to save, which is being present at the moment of publishing.
That trade is fine at small scale. Someone posting to their own LinkedIn three times a week can paste a comment three times a week. It stops being fine when the posts multiply, when publish times drift into nights and weekends because that is when the audience is on, or when you run client accounts and the publish moment belongs to nobody in particular. That is the point where the feature is worth paying for, and it usually arrives bundled inside a scheduler you wanted for other reasons. For what the free tiers still include, free scheduler plans compared keeps the current numbers.
On Instagram, use a scheduler that explicitly supports first comments for the format and account type you publish. On TikTok, the official Content Posting API does not create comments, so add it manually after publication. On LinkedIn, verify the scheduler's current comment permissions and feature documentation. The free fallback on every platform is manual.
