Markdown
Easy for AI to write.
Plain for the people reading it, with no room for a document’s shape: cover, page breaks, layout.
The Mac workspace for HTML documents
Would you send
that AI draft
to a client as is?
HTMLoop is a Mac workspace for turning AI drafts into documents you’d send to a client. It flags the figures and promises it couldn’t find in your own files, lets you fix just that part, and changes nothing until you compare and apply.

Why HTML
A document both AI
and people can read.
Markdown, Word and PowerPoint will keep their place. But documents that AI and people make together need a common base: easy for AI to write and revise, and ready for people to read and use. HTML sits in between.
Easier for AIFamiliar to people
HTML
Easy for AI to write and revise. People read it right in a browser.
Layout, tables, print size and form fields, all in one file.
PPT · Word
Familiar to people.
Awkward for AI to edit precisely, down to the layout.
Building an HTML document by hand used to take a long time. Now AI writes it fluently, and you check and refine.
What we believeIn an era when people no longer write first drafts from scratch, HTML will become the universal foundation for documents. HTMLoop is building that future.
The workflow
From your material
to a finished file.
Start with existing HTML, or create a new document from your own material.
↳What you finish becomes the starting point for what’s next. Reopen it and carry over its structure and feedback guidelines.
- 01 · Sources
Start with what you know
Describe your goal, add notes and attach reference files. Or begin with an HTML draft you already have.
- 02 · Research · revise
Research, then refine with AI
Research public information and revise selected sections with AI. Facts your material does not support stay marked for checking.
- 03 · Review
You review, then apply
Compare each draft with the original. Check facts, figures and layout, then apply and save.
- 04 · Share
Send the finished file
Share HTML, or PDF for supported formats. Recipients open it in a browser without HTMLoop.
Illustrative scenarios · not customer testimonials
A polished draft still needs
your knowledge.
The proposal looks good. Your team’s context is missing.
Before
An AI-generated HTML proposal looks polished, but misses the actual scope and client requirements. You still need to explain the gaps and transfer the revisions.
With HTMLoop
Open the draft and include the relevant material and constraints in your revision request. Select the section to refine with AI, compare the changes, and apply and save what you have checked.
Rewriting last month’s report from scratch?
Before
Same structure every month, yet you explain the metric definitions and tone to the AI all over again.
With HTMLoop
Open last month’s finished HTML and carry over its structure and feedback guidelines. Attach the new data, recheck last month’s figures yourself, then apply and save.
The other side
Open in a browser.
Keep a PDF.
Your recipient can read the document without HTMLoop. Try an exported example, including its built-in PDF download.

A few things to know
AI is optional
Read, edit text, and save existing HTML without an AI account.
Bring Claude Code or Codex
Create using your own account. Provider charges are separate; material you send is handled under their policies.
Review, then apply
AI changes arrive as drafts. Check facts, figures, and document layout before applying and saving.
