Posting the same piece to Zhihu, Xiaohongshu, and Douyin usually means logging into each platform, pasting, and re-formatting — half an hour gone. MultiPost compresses that into one pass: fill the content once in its browser extension, check the target platforms, and it opens each platform’s publish page, adapts character limits, hashtags, and image sizes, then fills the form for you — confirm and it goes. The download page claims coverage of 44+ social platforms.

Core Purpose

MultiPost differs from API-based schedulers like Buffer: it requires no platform API keys at all. The extension fills the destination platform’s own publish form, which is why it covers Chinese and international platforms alike — the extension repo’s README lists Zhihu, Weibo, Xiaohongshu, Douyin, TikTok, YouTube, and more. Content spans text, images, and video; a dashboard adds AI video transcription, and desktop apps for macOS/Windows (public beta) bring local automation. Developers get two integrations: an extension API callable from your own web app, and a RESTful API for scripts and servers.

Key Scenarios

  1. Multi-account operators: distribute one post across platforms in a single pass and confirm each draft, without re-pasting.
  2. Cross-border creators: make posting to both Chinese and Western platforms the default, with no per-platform formatting.
  3. Repurposing: transcribe a video into text and subtitles first, then distribute it as written content.

Trying it and its limits

Install from the Chrome Web Store or Edge Add-ons; no signup and no API key needed (multipost.app → Download, desktop installers on the same page). Three caveats: the site says “100% open source, free forever,” but the extension repo’s README states this repository maintains the Apache-2.0 components while the Chrome/Edge store packages are built from a monorepo that includes a proprietary Agent module — open source covers part of the product. Because publishing works by filling real platform pages, a platform redesign can break flows until the extension updates. And the desktop app is a public beta. If you want a heavier agent-style distributor, compare the open-source AiToEarn.
