Real-Time Counter

The SocialCal editor shows live character counts for each selected platform. Red indicates you've exceeded the limit.

Going past the single-post limit

X, Threads, and Bluesky all support thread mode in SocialCal — chain multiple posts into a connected reply chain so you can publish content longer than the single-post ceiling. Search the help center for "Post threads" for the full walkthrough, including the Split from long text dialog that breaks a long draft into properly-sized posts on sentence boundaries.
