Markloop is a web app for reviewing agent-made HTML documents. Share specs, reports, and proposals, collect comments and answers in context, then send the feedback back to your agent.
For HTML documents — not live websites or shipped apps.

How orders stay in sync between Lumen Commerce and Atlas ERP.
Native MCP for Claude Code and Codex — push and pull without leaving the terminal. Other agents can use the same feedback as plain files.
Coding agents don't just write code anymore. They draft specs, reports, proposals, and technical docs. Markdown is fine for agents, but HTML is better when people need to understand, review, or approve the work. The problem starts when feedback moves to Google Docs, Slack, email, or screenshots — the structure breaks, comments scatter, and you become the person copying everything back into the agent.
Paste an HTML artifact into a Doc and the layout, code blocks and structure fall apart.
Slack, email, screenshots — nothing anchored to the actual line it's about.
You hand-translate every comment back into a prompt for your agent.

Projects hold your files, versions, comments, and questions.
markloop_put_version("order-sync")
Upload HTML yourself, or let your agent send it over MCP. It appears in Markloop as a versioned document.
Invite Viewers to a project when you want comments. Share a single read-only file link when someone only needs to read.
Customer places the order in Lumen Commerce.
1Atlas reserves stock for each line item.
Confirmation is sent once stock is held.
Viewers comment on exact parts of the document, answer your questions, and see the discussion in context. No agent needed on their side.
Your agent pulls every thread back over MCP as structured context — target, quote, intent, version. No copy-paste.
order.paid webhook that doesn't exist yet.Your agent applies changes locally and publishes v2. Markloop keeps the comments, marks what's addressed, and leaves open questions for the next round.
Pin a section or a single sentence. Comments stay anchored to the exact spot and stay attached to the version they were made on. Built for dense specs and docs.
Feedback your agent can read. Every comment exports with its selector, quote and context — ready to apply in one pass.
Reviewers see the rendered document, not the source file.
Comments live on their version; new revisions check off what's done.
Invite clients and teammates as reviewers — never charged per reviewer.
Ask reviewers directly inside the document. Their answers come back to your agent with the rest of the feedback.
Other tools collect feedback. Markloop packages it for your agent. Every open comment comes back with its target, quote, reviewer intent, surrounding context, and version — over MCP or as plain files. No copy-pasting comments into prompts. No guessing what "that section" meant.
Plain files. Any agent. Nothing runs on our servers — you apply changes locally and stay in control.
Share a PRD or product spec, collect comments and answers, and let your agent fold them into the next version.
RFCs, architecture docs, migration plans — comment on the exact line, answer open questions, and track what's addressed across revisions. The feedback comes back ready for your agent.
Reports, proposals, audits — send a professional HTML artifact instead of a messy attachment. Clients comment and answer the questions you embed, all in one place, scoped to just their project.
Research, strategy docs, plans, analyses — if your agent writes it as a doc, you can share it, gather comments and answers, and loop the feedback straight back.
Reviewers see the document in the browser, not the raw HTML file.
People see only the projects or files you share with them. Nothing is shared by default.
Project Viewers can comment and answer questions, but they can't add files, edit documents, see billing, or access other projects.

Google Docs and Notion are great for writing. Markloop is built for the review loop around agent-made HTML documents: comments, answers, versions, and feedback your agent can use.
Invite people to a project as Viewers when you want comments and answers. Or share one file as a read-only private or public link, with expiry and version access controls. Reviewers are always free.
Claude Code and Codex connect natively over MCP — your agent pushes and pulls without leaving the terminal. Any other tool still works: the feedback also exports as plain files, so bring your own.
No. Your agent applies changes locally, on your machine. Nothing runs on our servers — you stay in control.
Yes. Reviewers see the rendered document, not the source file. Project access is scoped, and single-file links can be private or public, with expiry and version visibility controls.
HTML artifacts your agent produces — specs, docs, reports, plans, research. Anything that renders as a self-contained HTML file. Each upload becomes a version in a chain.
Markloop is built for self-contained HTML artifacts and documents — the kind your agent outputs — not live, multi-page web apps. If it renders from a single HTML file, it works.
No perpetual free tier, but every account starts with a 14-day free trial — no credit card required. You pick a plan later, in the app, and reviewers are always free.
A project is one client, team, or workstream. It holds files, versions, comments, questions, and the Viewers you invite.
Yes. Plans are monthly or annual — cancel whenever, no lock-in.
Your agent creates the document. People review it in Markloop. Your agent pulls the feedback and publishes the next version. Start your 14-day free trial today.
