## Character limits it writes to

Autoadify writes each platform's version to that platform's limit. The number that matters most is often the preview: the part shown before "more".

| Platform | Spec | Note |
| --- | --- | --- |
| X / Twitter | 280 characters | No preview cut — the whole post shows. |
| Instagram | 2,200 characters | About 125 show before the cut (truncated in feed). |
| LinkedIn | 3,000 characters | About 210 show before the cut (truncated in feed). |
| TikTok | 2,200 characters | About 100 show before the cut (truncated in feed). |
| YouTube | 5,000 characters | About 157 show before the cut (truncated in search). |
| Facebook | 63,206 characters | About 480 show before the cut (truncated in feed). |
