Or build it yourself with the API.

How it works with AI

You talk. AI publishes.

Connect your social accounts in Solnk. Then just tell any AI what to post — it handles the API call, formatting, and delivery.

You say

“Write a casual post about our launch and publish to X, LinkedIn, and Threads.”
