What each network supports and its limits.
| Network | Supports | Good to know |
|---|---|---|
| Threads | Text (500 chars), images, video, carousels, link card on text posts, first reply, replies | Only the first hashtag is recognised by Threads. |
| Profile and Company Pages: text (3,000), article links, images, multi-image, video, first comment, comments | Page analytics need LinkedIn's approval of our app; personal posts expose likes and comments only. Reconnect every 60 days unless LinkedIn allows refresh. | |
| X | Text (280, links count as 23), up to 4 images or 1 video, alt text, first reply, replies & mentions | Reading replies/mentions and impressions require X's paid API tier. |
| Image pins with title, description and destination link, pin analytics | Pick the board in the composer's Pinterest options. Video pins are coming. | |
| YouTube | Video with title, description, tags, category, visibility, made-for-kids flag; native scheduling; comment threads | YouTube's daily quota allows roughly six uploads per app per day. |
If a network can't do something, the composer says Not supported by this network/API instead of pretending. We never simulate a feature a network doesn't offer.
