Microposter.so

MicroPoster lets users write a post in their preferred social app and have it automatically detected, reformatted, and republished on X, Threads, Bluesky, and Mastodon. The service monitors designated source accounts, adapts content to each platform’s character limits, media dimensions, and formatting rules, and then publishes the adapted version without requiring manual copy‑and‑paste. It also splits long posts into threads or carousels, checks video formats, and generates appropriate link cards.

The tool is aimed at creators and anyone who maintains a presence on multiple text‑based networks but wants to avoid the overhead of separate schedulers or API integrations. By handling cross‑posting in the background, it promises to increase reach across platforms while keeping the posting experience native to the original app.

What distinguishes MicroPoster is its focus on native detection and platform‑specific formatting rather than a generic scheduler. It claims to support the latest features of each service, offering a streamlined workflow that can be set up in seconds and runs automatically without additional dashboards.
