Write once. Tailor it for every network.
One composer with per-platform captions, live previews and character counters, built for the post types each network supports.
What it does
Per-platform captions
Start with one caption, then adjust it for each network. A short punchy line for X, a longer story for LinkedIn, hashtags for Instagram - all in one post.
Live previews and character counters
See roughly how your post will look on each network and how many characters you have left, so nothing gets cut off.
Every format, where the platform allows it
- Instagram: feed posts, carousels, Reels and Stories
- Facebook Pages: posts, photos, videos, Reels and Stories
- YouTube: videos and Shorts, with title, description, custom thumbnail and audience settings
- TikTok: videos and photo posts, with TikTok's privacy and interaction options
- LinkedIn: text, images, PDF and PowerPoint document carousels, and video
- X, Threads and Bluesky: single posts and threads
- Pinterest: Pins with title, description, link and board
- Google Business Profile: updates, events and offers for each location, with a photo and a button
First comment
Add a first comment that posts straight after your post - useful for links or extra hashtags. Available on Creator and above, on platforms that allow it.
Alt text and thumbnails
Add alt text to images so everyone can enjoy your content, and choose a custom thumbnail or cover for videos where the platform supports it.
Plans: The composer is on every plan. First comment needs Creator or above. Compare plans
