Markup
A private cross-service home for AI-generated HTML
Last verified:
What is Markup?
Markup from Sprout is a private, cross-service storage platform specifically designed for AI-generated HTML files. It acts like Google Drive for HTML output from Claude, ChatGPT, Gemini, and other AI tools, allowing users to upload, store in folders, view in-browser, and share with safe links.
Key features include isolated sandbox rendering for each file (security), private-by-default sharing with specific people, folder organization for managing multiple HTML files, and instant browser viewing without downloads. The tool solves the clumsy workflow of downloading HTML files from AI tools and sending them via chat/email.
Markup is ideal for professionals and teams who frequently use AI to generate presentations, slides, one-pagers, reports, and docs in HTML format. It's for anyone who needs to share AI-generated HTML securely without public/indexable links tied to specific AI services.
The service is currently free to try and use, with paid team and company plans coming shortly. Each rendered file runs in an isolated sandbox for security, and links are safe (non-public, non-indexable) unlike native AI service shares.

Frequently asked questions about Markup

What problem does Markup solve?
Markup solves the clumsy workflow of sharing AI-generated HTML output. Previously you had to download HTML files and send them via chat or email, hoping they opened correctly.

Yes, Markup is private by default. Files are not public or indexable by search engines. You share with specific people only via safe links, unlike native AI service shares that may be public.
How does sandbox rendering work?
Each file renders in an isolated sandbox for security. This means uploaded HTML runs in a contained browser environment, preventing potential security issues from arbitrary HTML code.
Can I organize files in folders?
Yes, Markup lets you keep uploaded HTML files in folders for organization, making it easy to manage multiple presentations, reports, or docs.

Do I need to download files to view them?

When will paid plans be available?
