CircleIt vs Marker.io

Marker.io turns feedback into issues, and your agent pulls one when you give it the link. CircleIt sends each change straight into the Claude Code or Codex session that’s already open, and the person who asked sees when it’s done.

CircleIt compared with Marker.io

Questions

Does Marker.io work with Claude Code?

Only when you hand it an issue. With Marker.io’s MCP server, you give your agent a Marker.io issue URL and it pulls that issue to work on. CircleIt sends each piece of feedback into the Claude Code or Codex session that’s already open, with no link to pass on.

Can CircleIt send text changes?

Yes. Select words on the page with the Text tool and type what they should say. The agent gets the old and new wording, with the text around it, so it changes the right words.

Can my clients use CircleIt without fuss?

Yes. They accept your invitation, create a free account and add the extension, in Chrome or Edge on a computer. Then they circle what they want changed and press Send. They don’t need Claude Code, Codex or a terminal, and they see Done when the agent has made the change.

Can I try CircleIt before I pay?

Yes. Your first 10 changes are free, with no card, and they don’t expire. A change is one press of Send. After that, Personal is $9 a month and Team is $25 a month.
