Post one update to every platform, worded for each
Tell your assistant what to announce. It writes a version for each platform, checks each one against that platform's limits, shows you the exact posts, and publishes or schedules them to the accounts you connected after you say yes.
Works on the free plan. Connect an assistant first if you have not: setup guides.
The prompt
We opened a second location and I want to announce it. Post it now to LinkedIn, Facebook, Threads and Bluesky with a version written for each platform, and use this image: [your image link]. Put the booking link [your booking link] in the first comment. Show me the exact posts before anything goes out.
Swap in your own details. Example links and names are placeholders.
What the assistant does
Each step names the Socialync tool the assistant calls. A step with no tool is the assistant's own work or yours.
- 1
Check accounts and allowance
Your assistant picks the brand, lists your connected accounts and flags any that need a reconnect. It reads your plan and your daily limit before it writes. If you saved an audience in Socialync, a named group of accounts, you can name it and the assistant targets that group.

Write a version for each platform
It rewrites the announcement for each platform's length and tone. The shared text goes in the caption and each platform's own text goes in a per-platform override. The link goes in the first comment.

Check the post
It validates the exact post it plans to send: text length per platform, link count, image type and size, and connection health. It fixes errors and tells you about warnings, such as a caption that would be cut short.

Show the post and wait
You see the profile, the platforms, the exact text for each, the image and the first comment.

Publish
On your yes, text and image posts go out right away. For a later time it schedules the post instead. It can also hold the post as a draft and publish it on your yes in the same chat.

Report each platform
It tells you the result for each platform, with the post link for each live post. For a scheduled post it lists the calendar.

What you will be asked to confirm
- The exact text for each platform, the image and the first comment.
- The platforms it will post to and the time.
- The yes that sends it. A change to any text shows the post again.
Socialync tells your assistant to show you the exact post and wait for your yes in the chat before it publishes, schedules, replies or cancels anything. The publishing tools are marked as destructive, so clients that honor that also ask you to allow each call. You can switch on a confirmation dialog on the API Keys page that shows the exact post inside clients that support it. Socialync records who approved each post and when.
What you need
Plan
The free plan works for every platform except X. Free allows 5 posts a calendar month, and one publish to many platforms counts as one post. Paid plans add X and unlimited posts.
Connected accounts
Each platform you want connected in Socialync.
Assistants
Claude (claude.ai, Desktop and Code), ChatGPT, Grok, Cursor, Codex and Gemini CLI connect to Socialync. Any other assistant that supports MCP can too.
Also
- An image as a public link, or attached in the chat if your assistant can pass images on. Instagram needs an image or a video on every post.
Example result
Illustrative example with made-up posts and numbers. It does not come from a real account, and yours will use your own content.
