One composer.
Every platform.

Write once,
post everywhere

Compose your post in a single editor and publish to every connected account simultaneously. Each platform renders its own preview — character limits, hashtags, and link handling all accounted for.

Auto-post the
perfect reply

Add a first comment that fires immediately after your post goes live. Use it for hashtag stacks, affiliate links, thread continuations, or CTAs you don't want cluttering your main copy.

• Fires within seconds of the main post
• Per-platform override supported
• Perfect for hashtag stacking on Instagram

Tailor every post
per account

One base post, multiple voices. Override the caption and first comment for each connected account. Your Bluesky audience gets the long-form take; your Threads followers get the hook.

• Override text per connected account
• Override first comment per account
• Fallback to global copy if no override set
