Count your Threads post in real time. Stay under the 500-character limit, keep replies sharp for conversations, and check how the same text fits every other platform.
Posts allow 500 characters. There is no in-feed truncation below the limit.
Schedule everything, post everywhere
Built for creators and teams
Paste your post
Type or paste your Threads post into the field. The counter updates instantly as you write.
Stay under 500
The progress bar turns as you approach the 500-character limit and shows exactly how many characters you have left for the post or reply.
Tighten for replies
Threads conversations chain reply after reply. Trim each post so it reads cleanly on its own and keeps the thread moving.
Lead with the point
Threads is text-first with no headline. Open with your strongest line so the post lands the moment it appears in the feed.
Plan a reply chain
Long thoughts split across linked replies. Keep each post under 500 characters and let the conversation carry the rest.
Repurpose across platforms
See instantly whether your Threads post also fits X, Instagram, Bluesky, and the rest before scheduling.
Match your Instagram voice
Threads is tied to your Instagram account. Keep tone and length consistent across both before you post.
500 characters is the hard ceiling
Threads posts cap at 500 characters. Unlike captions on other platforms, there is no "more" link, the whole post shows, so stay within the limit rather than relying on a cutoff.
Break long ideas into a chain
When a thought runs past 500 characters, reply to your own post to continue. Linked replies read as one conversation and often outperform a single dense post.
Your audience comes from Instagram
Threads accounts are linked to Instagram, so your followers expect a familiar voice. A consistent tone across both helps the post connect faster.
Emoji can count as more than one character
Some emoji (skin-tone and combined emoji) use multiple Unicode units. If your post is emoji-heavy, verify the final count in the Threads app.
Next step
Post your Threads draft everywhere it fits
Once your post sits comfortably under 500 characters, decide where else it belongs. A simple schedule for your social media posts keeps the cadence steady, and knowing how X and LinkedIn differ helps you adapt the tone per network. Built for content creators who publish across many feeds at once.
