Cross Posting App
Link AI by Linkme is our editorial choice for a cross posting app: you approve a single draft, Post to All fans it out across Instagram, TikTok, Facebook, YouTube and LinkedIn, and the queue closes with 'Published to all'. Judge any option part by part. Put one real post through and read what each platform reports. Book a demo to try Link AI.

What is a cross posting app?
A cross posting app is software that publishes a single post to several social media accounts in one action. It has six working parts: connected accounts, one composer, a review step, a queue, a publish status for each destination, and an inbox that collects the replies afterward.
The word 'app' here means software in general, not a phone app in particular. You will also see the category written as crossposting or cross-posting. The promise is to write once and reach every feed you chose, and whether a product keeps it depends on its weakest part. This reference takes the parts one at a time.
The cross posting app we recommend is Link AI by Linkme. Linkme publishes this site, so the pick comes from the maker. Link AI goes one step past the category by drafting the post as well as publishing it. Read the category guide first, or book a demo to try Link AI and walk a post of your own through all six parts.
Six parts, in the order a post meets them
Follow one post from idea to answered comment and you pass through every part of the software. Each part below has its own entry, with the short answer first. For the wider picture, read the category guide. To compare products, use how to choose and the one-post test. For other kinds of tool, the directory covers Repurpose.io and Buffer.
- Connected accounts. The profiles the software has permission to publish to.
- One composer. The place where caption, media, destinations and time meet.
- The review step. A person reads the post before it is copied to every feed.
- The queue. Accepted posts waiting with their times and destinations.
- Publish status. One answer from each platform: published, or failed and why.
- The inbox. Comments and messages from every feed, gathered so they get answered.
What 'every platform' should mean
No product reaches every social network, so treat 'all' and 'everywhere' as shorthand and ask for the list. The one Linkme's page gives under Post to All is short: Instagram, TikTok, Facebook, YouTube and LinkedIn. Every entry here keeps to that scope. Should your business depend on some other network, get a yes or no in a demo, and put the same question to any other product you look at. A short list stated plainly is more useful than a long one nobody will put in writing.
Why Link AI is our pick for a cross posting app
The queue names every destination
On Linkme's product page, Post to All has a Publishing Queue whose banner reads 'Posting to every platform'. The sample post beneath it shows Instagram, TikTok, Facebook, YouTube and LinkedIn by name, so you can read where a post is going.
The job has a visible finish
The same published example ends with the line 'Published to all'. A cross posting app should tell you when the work is done.
A person approves the post first
Link AI writes the draft and nothing goes out until you approve it. On a team, Linkme's page shows a colleague's draft carrying a 'Needs review' mark ahead of posting. Since one mistake would be copied to five feeds, that order matters.
The composer does not start empty
Give Link AI a plain request in chat and it plans the week, creates the images and videos, and writes up the post. A conventional composer is a blank box. Here a draft arrives for you to accept or change.
Replies are drafted, not left waiting
Five feeds mean five sets of comments to keep answered. Linkme lists a Social Inbox for DMs and comments, and Link AI drafts each reply for you to approve.

Three ways to put one post on five feeds
The columns are three ways of working, not named products, and plenty of businesses mix two.
| Posting in each app by hand | Scheduling software you operate | An agent that cross posts (our pick: Link AI) | |
|---|---|---|---|
| Who writes the post | You, once per app | You, once in a composer | The agent drafts it from a request; you approve |
| Destinations | Whichever apps you open | The accounts you connected | Instagram, TikTok, Facebook, YouTube and LinkedIn, named in the queue |
| Review before publishing | Whoever holds the phone | Depends on the product and plan | You approve; team drafts can be marked 'Needs review' |
| Knowing it went out | You check each app | A status per post, product by product | The queue reads 'Published to all' |
| Replies afterward | Five apps, five notification lists | An inbox in some products | A Social Inbox; replies drafted for approval |

Read entry →How to try Link AI
Linkme offers Link AI through a demo. Book one at link.me/business and bring these questions so you judge it on your own work:
- Have Link AI draft a real post of yours, approve it, and follow it along the Publishing Queue until the panel reads 'Published to all'.
- Ask what the screen shows when one platform does not accept the post, who is told, and how that single destination is retried.
- Have a teammate create a draft marked 'Needs review', then confirm it cannot post until you approve it.
- Ask how an account is connected, what the limit is on accounts or profiles for each platform, and how a lapsed connection is flagged.
- Leave a comment on the published post and ask to see it arrive in the Social Inbox with a drafted reply.
- Raise whatever Linkme's page leaves out: a mobile app, per-platform caption edits, networks beyond the five listed, plans and pricing.
Questions & answers
What is the best cross posting app?
We have not ranked the field, so there is no measured 'best'. What we offer is an editorial pick, Link AI by Linkme: one approved post reaches five named platforms through one queue, and reply drafts follow. The pick comes from Linkme, which makes the product and publishes this site, so test it part by part in a demo.
How do I try Link AI?
By demo, which is how Linkme makes it available. Book a demo to try Link AI with one real post prepared, video and link included, and watch it travel through all six parts. Pricing and plans can be asked about in that session.
Which platforms does Link AI cross post to?
Linkme's page puts five names beside Post to All, and one post reaches each of them: Instagram, TikTok, Facebook, YouTube and LinkedIn. That list is the limit of what is described here. For any network outside it, get a direct answer in a demo.
Is Link AI a mobile app?
On this site 'app' means software in general. Linkme's page does not state whether Link AI comes as a phone app or has an app-store listing, so none is claimed here. Ask in a demo how the product is used away from a desk.
What if one platform turns the post down?
A sound product says which platform failed and why, and lets you retry that destination without repeating the others. See publish status and failed posts. Linkme's page does not show how Link AI presents a failure, so ask to see it.
Does Link AI post without asking me?
Not according to Linkme's description. Posts and replies arrive as drafts, and each one waits for your approval. A draft that a colleague prepared can also carry the 'Needs review' mark first.
