Posting the same text to five networks by hand is slow and usually goes wrong somewhere. Straight copy-paste breaks for predictable reasons; the workflow we use in fanout is one master draft, a version for each network, and a single publish or schedule step.
Every network has its own rules, and they do not line up. A post that fits on LinkedIn is far too long for X. A caption that works on Instagram has no use for a link, because links in captions are not clickable there.
The first problem is length. Character caps range from a few hundred to tens of thousands, so one text rarely fits everywhere. The second is media: how many images a post can carry, whether video can be mixed with images, and whether the network accepts a text-only post at all. The third is tone. A dry, complete paragraph reads well on LinkedIn and flat on Threads.
Pasting the same block everywhere means you either write for the strictest network and waste room on the others, or you get a rejected post and have to fix it under time pressure.
Here is the sequence in fanout, from nothing to published.
While you edit the master text, the character counter checks it against the strictest limit among the networks that are still using that master text. If you have picked X and LinkedIn, the counter stops you at the X cap.
Once you give a network its own version, that network leaves the group. So the practical pattern is to write one short master for the tight networks and give the roomy ones, such as LinkedIn, a longer tab of their own. Every network is also checked on its own cap before anything is sent.
The image cap works the same way as the text cap: the composer uses the lowest image limit among your selected networks. Add a video and it has to be the only attachment, since a post can hold one video and cannot mix video with images.
Some networks cannot publish text alone. Instagram needs an image or video, YouTube and TikTok need a video, and Pinterest needs an image. The composer flags these before you send, so you find out while editing and not after.
A short pass catches most mistakes.
The most common one is leaving network-specific wording in a post that goes elsewhere. "Link in bio" means something on Instagram and nothing on X. "Replying to this thread" means nothing on a network with no threads. Read each version as if it were the only post you made that day.
The second is writing for the longest network and trimming blindly. When you cut a long post with a character count in mind, the ending usually goes first, and the ending is often where the point was. Rewrite short posts from the point outward instead of cutting from the bottom.
The third is posting the same media everywhere without looking at it. A wide image that works on one feed can be cropped badly on another. The composer preview shows each network, so use it.
The workflow is the same if you run one account per network or several. You can connect more than one account on a network and choose which ones receive a given post. That is useful if you run a personal profile and a company page, and want some posts on both and some on only one.
The number of accounts you can connect depends on your plan, so check the pricing page before you plan a large setup.

Yes. Write one draft, select the accounts you want, and publish or schedule. Each network gets its own version of the post, which you can edit before it goes out.
Identical text pasted everywhere often reads wrong on some networks. Adjusting length, links and tone per network avoids that, which is why fanout lets you edit each network's version.
You connect each network once through its own permission screen. After that you post from fanout without logging in to each network.
The composer counts against the strictest limit among networks sharing the master text, and each network is checked against its own cap, so an over-limit post is flagged before sending.
