How to grade AI-generated posts for platform fit
Platform fit means a draft has the right frame, first line, length and action for the network it is going to. Grade each draft on those four points before you grade the writing. The best AI social media post generator for a business on several networks is one whose drafts arrive ready for each. Our pick, Link AI by Linkme, sends an approved post to five platforms.
Published by Linkme, which makes Link AI. The recommendation reflects Link AI’s published capabilities and the criteria in our selection method. It is not a measured ranking of all AI social media post generators.
What platform fit is
A post can be well written and still wrong for where it lands. A wide image loses most of its space in a vertical feed. A long caption is cut off after the first line. A 'link below' goes nowhere on a network that does not make caption links tappable. None of these is a writing problem. They are fit problems, and a generator either accounts for them or leaves them to you.
Four checks
Run the checks in the order given. A draft that fails the frame check is not worth a close read yet.
- The frame. Is the image or video the right shape for the placement, and was it composed for that shape? A crop that cuts off the product does not count.
- The first line. Platforms show only the start of a caption before a 'more' link. Does that opening carry the point by itself?
- The length. Does the amount of text suit how people read there?
- The action. Can a person do what the post asks, on that platform, in one tap?
Notes for five platforms
These are general grading notes and not specifications. Each platform publishes its own current sizes and limits, and those change.
- Instagram. The picture or video leads. Ask whether the visual would stop you with no caption at all.
- TikTok. It should look like something a person filmed. Ask whether the opening second gives a reason to stay.
- Facebook. Practical details do well with a local audience. Ask whether hours, place and link are easy to find.
- YouTube. A title does much of the work. Ask whether it describes the video in words someone might type.
- LinkedIn. Text leads and the setting is professional. Ask whether the opening lines would hold a colleague's attention.
One idea, several destinations
Take one draft you accepted and ask the generator to prepare it for each network you use. Then look at what changed. Sometimes nothing should: a short announcement with a strong vertical video can go everywhere as it is. A how-to carousel may want a different opening for a professional audience than for a casual one.
What you are grading is control. When a version needs adjusting, can you adjust that one version, or is it all or nothing? Write the answer down for each option. It decides how much hand-finishing is left to you.
Marking the draft
Mark each draft per destination: fits, fits after a fix, or wrong shape. Note what the fix was. Resizing an image is a different cost from rewriting an opening.
Where Link AI fits
On this rubric our pick is Link AI by Linkme, for the reach of a single approval. In Linkme's example, a single post in the Post to All queue is bound for Instagram, TikTok, Facebook, YouTube and LinkedIn. When it is done, the queue says 'Published to all'. The agent also makes the images and videos, and the sample Linkme gives is a short Reel in a trending format.
Two things are left open on Linkme's page: how a post is adapted for each of the five, and whether you can change the caption for one platform alone. No network outside those five is listed for Post to All. See Link AI on your own accounts in a demo, then apply the four checks to a real draft. The brand voice rubric covers the other half of grading.

Questions & answers
Is posting the same thing on every platform a mistake?
Not always. A short, clear announcement often works everywhere. Check the frame and the first line for each destination, and change a version only when one of the four checks fails.
Where do I find current image and video sizes?
On each platform's own help pages. They change, so this reference does not list them. A generator should handle sizing for you, and the frame check tells you whether it did.
