How do I add a collaborator to a post?

On the caption screen, tap Tag people and choose Invite collaborator, then search for the username. up to 5 collaborators can be added to the same post.

Can I add a collaborator after posting?

Yes: collaborators can be invited before sharing and added or removed at any time after publishing. Doing it up front is still better, because a late invite means the post has already been shown to one audience without the other account attached.

Who can edit or delete a collab post?

The author does: the original author keeps control of the caption and can delete the post, while the collaborator cannot edit it. Agree on the caption before publishing, because the collaborator has no way to change it later.

Instagram collab posts, explained

Last verified: 2026-07-28

A collab is one post published jointly by two or more accounts. an accepted collab appears on both profiles with both usernames in the post header, from a single shared copy of the post, and likes, views and comments are pooled on that one shared post rather than counted separately per account. Invite from the Tag people screen.

How to invite a collaborator on an Instagram post

1
Create the post as normal
Choose your photo, carousel or Reel and continue to the caption screen — collabs are offered on feed posts and reels through Tag people, and not on stories.
2
Open Tag people
On the caption screen, tap Tag people, then choose Invite collaborator rather than tagging the account in the image.
3
Search and select the account
Type the username and tap the account. Since up to 5 collaborators can be added to the same post, add everyone here before you continue.
4
Post and wait for acceptance
Share the post. until the invite is accepted the post appears only on the author's profile, and the invited account shows as pending — the other account gets the invite in their notifications or requests.

What a collab post actually is

It is not two copies of the same post. an accepted collab appears on both profiles with both usernames in the post header, from a single shared copy of the post. One post, two front doors — which is the whole point, because it puts the same content in front of two audiences without either account reposting anything.

Engagement is pooled as well: likes, views and comments are pooled on that one shared post rather than counted separately per account. That matters more than it sounds, because comments stay in one conversation instead of splitting across two threads, and neither account is competing with a near-identical post.

Sending the invite

The control lives on the Tag people screen, which is why so many people never find it — it looks like tagging, but Invite collaborator is a separate option, and up to 5 collaborators can be added to the same post.

If the option is missing entirely, it is usually the format or the account type rather than a bug: collabs are offered on feed posts and reels through Tag people, and not on stories, so check you are posting a supported format before assuming something is broken.

What happens after you invite someone

The post goes live straight away, but only halfway: until the invite is accepted the post appears only on the author's profile, and the invited account shows as pending. The invited account sees a request and can accept or ignore it, and the post becomes a genuine two-profile post at the moment they accept.

If they never accept, nothing breaks. a declined or ignored invite leaves the post live on the author's account alone, and nothing is published to the invited profile, so an ignored invite is not a reason to delete the post and start again.

Invite outcomes
Outcome	What the post does
Accepted	Appears on both profiles and in both audiences' feeds
Pending	Live on the author's profile only, invite still open
Declined or ignored	Stays a normal single-author post

Who controls the post afterwards

Control is not shared evenly: the original author keeps control of the caption and can delete the post, while the collaborator cannot edit it. That is the asymmetry worth agreeing on in advance, because the collaborator is lending their audience rather than co-owning the post.

There is an exit. a collaborator can remove themselves later via Options then Stop sharing, and the post stays on the original creator's profile — useful if a caption is edited into something you would not have signed off on.

When collabs are worth using

Collabs work when both audiences plausibly want the same thing: a joint launch, an event you both attended, a customer story, a guest appearance. They work badly as a reach trick between unrelated accounts, because the mismatch shows up immediately in the engagement.

Agree who writes the caption before the post goes up, since only the author can change it.
Send the invite while you are still on the caption screen; a post published without it has already been served to one audience alone.
Keep the collaborator relevant; borrowed reach from the wrong audience does not convert.

When collabs and partner posts are stacking up across several accounts, an AI social media manager can plan the calendar, draft each post in the right voice, and hold everything for approval.
