Markloop is built for the review loop. Client work needs a lock, a domain and a read receipt too. Markloop ties comments to sentences and feeds them back to your AI for the next version. Stacktree runs the same loop, and adds what a client deliverable needs: a passcode or email gate, your own domain, who read it and for how long, sign-off, and a portal per client.

Stacktree, when the reader is a client. Both host an AI-written page at one link and send reviewers' comments back to your AI for the next version. Stacktree adds a passcode or company-email gate with no account, your own domain, reading data per named person, sign-off, and a client space that collects every deliverable. ## What Markloop does well Markloop’s idea is tight: your AI writes the document, people comment on exact sentences, and the AI reads those comments (over MCP for Claude, ChatGPT, Cursor and Grok, or as plain files) and publishes the next version at the same link. Each comment is tied to the version it was made on. One digest email per document instead of a ping per comment. Reviewers are free and unlimited, and the app and database run in Frankfurt and London, which matters to some European clients. ## Where Stacktree differs - A lock the client can open. Markloop states links cannot be password-protected; verified identity means an email invite and a sign-in. Stacktree puts a passcode on any page on every plan, and from Solo an email-domain check, with no account for the reader. - Your own domain. A page, or a whole client portal, on an address you own, from Solo. Custom domains are not documented on Markloop’s page. - Who read it. A named link per person, with opens and reading time coming back by name: “Read by Maya Cole · 24 min over 8 visits”. Analytics are not documented on Markloop’s page. - Sign-off. Comments say what to change; sign-off records who approved which version. Stacktree keeps both on the page. - More than one document. Stacktree hosts multi-file pages and dashboards, and a [client space](/client-spaces) collects everything you have sent one client. Markloop is built for single documents, not sites. ## Where Markloop is the better choice - Sentence-level review of long documents. Comments pinned to exact sentences and versions, read back by your AI as structured files, is a finer instrument than page-level comments for a fifty-page spec. - EU hosting by default. If your client requires data to stay in the EU, Markloop says so plainly. - Teams of five on one plan. Team at $49 a month covers five seats. Stacktree has one login per workspace today. ## Stacktree vs. Markloop Criterion Markloop Stacktree Comments flow back to your AI Yes, per sentence and version, over MCP or files.

FAQ ## Frequent questions What is Markloop? + Markloop hosts one HTML document your AI wrote at a single link. Reviewers comment on specific sentences, your AI pulls the comments back over MCP or as plain files, and publishes the next version to the same link. It is run from Krakow, hosts in Frankfurt and London, and costs $19 or $49 a month after a 14-day trial. Can I password-protect a Markloop link? + No. Markloop states links cannot be password-protected. Links can be private or public, can expire and be revoked, and verified identity means inviting people by email so they sign in. Stacktree puts a passcode on any page on every plan, and from Solo an email-domain check, with no account for the reader. Does Stacktree send comments back to my AI like Markloop? + Yes. Comments land on the page, anchored to what they are about, and the Stacktree connector lets Claude or ChatGPT read them, resolve them and publish the revision to the same link. Markloop ties each comment to a sentence and a version, which is finer-grained for long documents. Markloop or Stacktree for client work? + Markloop if the job is a long document reviewed sentence by sentence, often inside your own team, and EU hosting matters. Stacktree if a client opens the page: a passcode or email gate, your own domain, a named link that tells you who read it and for how long, sign-off, and a portal per client. Is there a free plan? + Markloop has a 14-day free trial and no free tier. Stacktree has a free plan: three pages, each live for seven days, longer once a reader opens one, with a passcode included. Paid plans start at $19 a month on both, and Stacktree never charges per seat.
