Posterr — AI writing for people who hate AI writing

AI writing that does not sound like AI marketing.

Posterr turns rough ideas into plain, believable posts for Reddit, blogs, X, LinkedIn, devlogs, and product updates.

Most AI writing is too polished.

It sounds confident, clean, and fake. That is a problem when your audience is skeptical, technical, or tired of engagement bait.
