Publish approved posts daily across five channels with a browser agent

The small team behind Yomates, a desktop app that runs AI agents in a real browser on the user's computer, gave one of its own agents a single job for November 3 to 8: publish the team's daily posts. A month of drafts was written with the agent and approved once by a person. Each morning at 9am New York time the agent opened Medium, Substack, X, Reddit and Pinterest in its browser and posted that day's items: articles with headings and links on Medium, notes and an emailed long post on Substack, posts on X (splitting long ones into two-post threads), pins with titles, descriptions and links across two boards on Pinterest, and answers to other people's questions on Reddit with no product name or links. It also signed up for the accounts and created one Pinterest board itself.

The agent published 28 of the 30 planned posts. A normal run of five posts took about 40 minutes and a catch-up run of nine took about 50, mostly spent waiting for pages and checking each post was live. Medium blocked text typed or pasted by a program, so the team wrote a small browser extension to insert the article. Google sign-in popups were blocked, so every account uses email and password. A person typed the Pinterest birthday and approved a switch to another subreddit. Reddit's own spam filter removed 4 of the 5 comments. The team gives no time-saved figure.

This is the vendor writing about its own product, so read it as a self-report. The schedule only runs while the desktop app is open, and it missed 3 of 6 nights; those posts went out on the next run. New Reddit accounts that comment daily get filtered, some subreddits remove comments from accounts under 30 days old, and some ban AI-written posts.
