What is Markloop?
Markloop is a web app designed for reviewing agent-made HTML documents. It enables teams to share specs, reports, and proposals, collect comments and answers in context, then send the feedback back to the agent. The platform uses anchored comments that pin feedback to exact sections or sentences, staying attached to the version they were made on. Agent-ready packages export every comment with its selector, quote, and context — ready for the agent to apply in one pass.
Who it's for
- Engineering teams that need to review technical specs and proposals written by coding agents without losing structure or context.
- Product managers who want to collect feedback from stakeholders on agent-drafted documents without becoming the middleman translating comments back into prompts.
- Technical writers collaborating with AI agents on documentation who need a clean workflow from draft to approval to revision.
Key features
Anchored comments
Comments pin to exact sections or sentences in the HTML document. Each comment stays attached to the version it was made on, so feedback never floats away when the document updates.
Agent-ready packages
Every comment exports with its selector, quote, and full context — structured for the agent to apply in one pass. No manual translation or copy-pasting needed.
Native MCP support
Markloop supports MCP for Claude Code and Codex, allowing agents to push and pull reviews directly from the terminal. Other agents can use the same feedback as plain files.
Unlimited free reviewers
Reviewers see only the rendered document, not the source file. You can invite as many viewers as you need without any charge.
What stands out
"The package is the whole point. Other tools collect feedback. Markloop packages it for your agent."
Most review tools stop at collecting comments. Markloop goes further by structuring every piece of feedback into a machine-readable package that agents can apply automatically. This eliminates the manual step of translating human feedback back into agent prompts, making the entire loop from agent to human and back truly seamless.
Worth checking out if…
You work with coding agents that produce HTML documents — specs, reports, proposals, or technical docs — and you need a clean way to get human feedback back into the agent's workflow. If you're tired of comments scattering across Slack, email, and Google Docs, or if you find yourself manually copying feedback into prompts, Markloop offers a purpose-built alternative.
