Postel

Postel is an AI-powered content creation platform built specifically for X (formerly Twitter). It analyzes your timeline and writing style to generate posts that genuinely sound like you, not generic AI output. Key features include a Speech-to-Post tool for turning spoken ideas into polished tweets, a knowledge base that lets you transform saved references into content with one click, and a viral outliers library with thousands of high-performing posts for inspiration. It also supports URL-to-post repurposing from YouTube, TikTok, and blog articles, plus full thread scheduling with natural posting time randomization. Built for creators, founders, and marketers who want to grow on X without spending hours writing every day.
