Postlia

Postlia is a social media management platform that enables users to write a single post and publish it across multiple social networks simultaneously. It supports LinkedIn, Bluesky, Instagram, TikTok, Pinterest, YouTube Shorts, and Mastodon, with X (Twitter) integration planned. The tool provides a unified composer for cross-posting, a visual calendar for scheduling posts, and AI-powered caption generation tailored to each platform's tone and length. Users can manage multiple accounts, making it suitable for agencies and multi-brand creators. Postlia also offers a feature called First Draft, which uses AI to draft a week's worth of social content based on the user's own material, with a quality gate to filter out low-quality AI-generated text. Additionally, it includes analytics dashboards that track engagement, follower growth, and optimal posting times across connected accounts. The platform includes over 25 free tools, such as a handle checker for username availability, and offers a public API with MCP server support for AI agents. It is built by a two-person team and provides a 7-day free trial, with paid Pro plans unlocking advanced capabilities like multi-account posting and shareable preview links for client approval.
