Use with a browser agent
Built for browser agents
In compatible browsers, an agent can configure profiles, write a version for each selected network, switch previews, and apply your edits through WebMCP.
Preview actions stay on this page and never publish or schedule posts. Scheduling is separate in SimplePost.
The post is empty.
Text is saved in this browser for 24 hours. Media must be added again.
Drafts and local media stay in this browser. No social account is needed.
Publish and schedule with SimplePost

How draft transfer works
SimplePost opens in a new tab. Sign up or log in, connect a social account, then explicitly import, review and schedule. Keep the same browser and device; saved text expires after 24 hours. Copy your text if you need to switch devices.
Only text and threads transfer; upload media again. DEV versions are excluded. Transfers allow up to 25 posts per version and 200,000 total text units. The trial allows 20 posts per thread. An existing composer draft asks for confirmation before replacement.

How the preview works
Previews are drawn by @simple-post/preview, the open-source renderer the SimplePost scheduler and its ChatGPT and Claude widgets use. Browser agents can fill in the editor through WebMCP. When you choose Schedule this draft, the text of each version opens in SimplePost as a draft; media, profile details and timing stay behind. The copy in your browser expires after 24 hours.

Publish platform-specific posts to the ten supported networks (DEV is preview-only), straight from ChatGPT, Claude, or your favorite AI assistant.
Previews are powered by @simple-post/preview, our open-source rendering library. SimplePost is open source too.
