Practical guide

Write the way people talk on Threads

Threads is a conversation feed, so short, direct posts and open questions fit the format. The preview shows the post the way it sits in the feed, with your name and handle in front of it.

The layout is simplified and Threads changes it often. Confirm the final result in the PostlyBee composer for the connected account.

Privacy: Your copy, account details, and any image you add stay in this browser tab. Nothing is uploaded to PostlyBee or an AI service.

Pro tips

Pro tips for Threads posts

Conversational length

A Threads post has 500 characters, which suits a short thought or a question. Use the badge to see how close you are.

Long ideas become a thread

If a post runs over, split it into a numbered chain of replies instead of cutting the idea. Put the main point in the first post.

Media is optional

Plain text posts perform well on Threads. Toggle the media off to see how the copy stands on its own.
