# Social media post composer with per-network previews

> Write your post once, tailor it for each network, and see exactly what will publish.

Great posts are written for the network they appear on, but rewriting the same idea for every channel takes hours. Tesselith's composer starts from one draft. Adjust the wording, media, alt text or first comment for any network, and your changes stay with that network while the rest of the post stays in sync.

### Write once, tailor anywhere

Start from one draft and customize the text, media and options for any network. Later edits to the main draft never overwrite what you've tailored.

### Accurate previews

See each post the way it will appear on every network, including crops, line breaks and character counts, before you schedule.

### Checks as you type

Character limits, media sizes and aspect ratios are checked for every network as you write, so problems are caught before you schedule.

## Questions people ask

### Can I write one post and send different versions to each network?

Yes. Write one draft, then adjust the text, hashtags or media for any network without starting over.

### Does the composer show what the post will actually look like?

Yes. Every network has its own preview, showing crops, line breaks and character counts exactly as they'll appear.

### What happens if my post is too long for a network?

The composer flags it as you type, so you can fix it before you schedule.
