AI that sounds like you, not a robot.
Not another generic wrapper. PostBuffer's AI writes social copy from your brand voice profile, suggests hashtags and picks posting times — so every draft sounds like you.
Captions, written
One line about your day becomes platform-native posts, written in your brand's voice rather than a robot's.
Hashtags, suggested
Relevant hashtag suggestions for every post, matched to your topic and audience — no copy-pasting a stale saved list.
Timing, chosen
Best-time suggestions slot each post into a good window for that network, so you stop guessing.

Turn a reel into a carousel, a thread and a LinkedIn note without rewriting a word.
Hear the difference.
