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 is most of this page.
The usual disclosure: we make one of the schedulers that does this, on Instagram, Facebook, and LinkedIn. The manual route is genuinely free and described below, and where no tool can do the job, which is TikTok, this page says so instead of pretending.
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 honesty note that 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, and whatever tool you use it is worth knowing which way it falls before a launch post is on the line.

Instagram's Five-Hashtag Limit Changed What the First Comment Is For
For years the feature had one famous job: thirty hashtags dumped in the first comment so the caption stayed clean. That job no longer exists. In December 2025 Instagram cut the limit from 30 hashtags to 5 per post and said posts carrying more than five are no longer recommended in Explore, on hashtag pages, or in Reels recommendations. A tool that lets you pile tags into the comment is now automating something Instagram actively discounts, and any page still selling the thirty-tag trick is describing 2023.
The first comment still earns its place, just for quieter jobs: five well-chosen tags under the post instead of inside the caption, a translation carrying the whole caption in a second language, credits for a photographer or collaborator, sources for a claim, or the extra paragraph of context that would push the caption past the fold. One habit does not transfer, though. On LinkedIn, parking the link in the first comment is a whole strategy, and it does nothing on Instagram, because links in Instagram comments are not tappable. The working link routes on Instagram remain the bio and the Story link sticker, and if the link sticker is the part you want to schedule, that has its own answer.
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, ours included, 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 and it works: schedule the video normally, catch the moment it goes live, post the comment from the app in the first minute or two, and pin it so replies do not push it down. A pinned comment holds the top spot no matter how busy the thread gets, which on TikTok matters, since the comment section is half the product. The trade is worth naming: TikTok is the one platform where the babysitting cannot be automated away, so if the first comment matters to the post, the publish time has to be one a human can attend.
Platform by Platform, Including LinkedIn
LinkedIn is where the first comment earns the most, because links in LinkedIn comments are clickable and posts that keep the link out of the body are widely believed to travel better. The catch sits on the tool side: LinkedIn only lets an app post comments through its Community Management API, a separate approval a scheduler has to apply for and earn. Plenty of tools schedule LinkedIn posts and only some can schedule the comment, which is why the free hunt tends to come up empty and why a feature list needs reading per platform rather than as one checkbox.
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 API has no way to create a comment. Post it yourself the moment the video is live, then pin it. |
| X and Threads | As a thread | Schedule the follow-up as a reply in the same chain. Same effect, different mechanism. |
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.
So: on Instagram yes, from any scheduler publishing through the official API, for feed posts and Reels on a professional account. On TikTok no, and no tool can change that, so the comment comes from you at publish time and gets pinned. On LinkedIn yes, provided the tool has earned LinkedIn's comment API approval, which is exactly why the free options are thin there. Free means manual on every platform, which is workable right up until the publishing schedule outgrows the human attached to it.
