Markdown
Easy for AI to write.
Suited to text and structure. Page layout depends on the tools used to present it.
Your material. Your AI. Your finished document.
Start with what
you know.
Finish with AI.
Bring your files, notes and existing drafts. Use AI to refine the parts that need work, review the changes, and finish your document in HTMLoop—without writing code.

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.

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 believeDocuments will increasingly start with accumulated material and experience, rather than a blank page. We believe HTML will become the common foundation for documents in the AI era. HTMLoop is building a workspace to finish them with AI and make each result a foundation for the next task.
The workflow
From your material
to a finished file.
Start with existing HTML, or create a new document from your own material.
↳Build on the work you have already finished. Reopen an existing HTML document, keep its structure, and choose the feedback guidelines you want to use with new material.
- 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 what is missing, select the part you want to change, and compare an AI revision without rewriting the whole document.
- 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 draft is a start.
Your work needs a finish.
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.
Try the shared HTML (new tab) ↗Created with sample material. Check your recipient’s browser and file-opening environment before sharing.
A few things to know
AI is optional
Read, edit text, and save existing HTML without an AI account.
Bring Claude Code or Codex
Connect your own AI account. English AI creation currently supports pages and slides. Provider charges are separate; their policies apply to material you send.
Review, then apply
AI changes arrive as drafts. Some figures and commitments are flagged for review against your inputs; this is not fact-checking. Review facts and layout before applying and saving.
