Surface makes AI-built websites maintainable.
The CMS for custom websites after AI builds them — a safe editorial layer for Markdown, MDX, components, media, and Git-backed publishing.
AI can create a beautiful custom site. Surface helps teams operate it: draft new content, protect developer-owned structure, review changes, publish through Git, and keep the repository as the source of truth.
The website is built. Now someone has to run it.
Modern AI tools and frontend frameworks make it easier than ever to launch a fast, bespoke website. But after launch, routine content work still falls back into the repo: Markdown files, MDX components, frontmatter, branches, pull requests, previews, and deploy status.
Surface turns that custom site into an editorially operable system — without moving content into WordPress, a headless CMS database, or a separate source of truth.
Draft
Write and revise content inside the safe regions of the file.
Paste
Bring in messy source material and prepare it for clean Markdown.
Generate
Use AI as a collaborator, not as an unsupervised repo editor.
Optimize
Improve metadata, accessibility, headings, links, and content quality.
Regionalize
Turn regional content from scattered files into focused family sessions for translation, review, and local adaptation.
One repository
Every Surface works through the same Git-backed source of truth.
The contract is the CMS.
Surface reads a repo-native editorial contract that tells it what the website is, where content lives, which fields are editable, which components are protected, how media should be handled, and how publishing should move through Git.
That contract gives humans and AI the same operating rules. Surface is the experience that enforces them.
For developers
Surface protects the structures your site depends on: MDX components, frontmatter, schema conventions, media paths, formatting, and clean Git diffs.
For editors
Surface turns repository content into focused workspaces for writing, cleanup, optimization, publishing, and regional content operations.
For AI agents
Surface gives AI rails. It can propose content changes through the contract instead of improvising raw file rewrites across the repo.
For the website
Git remains the durable home for content, configuration, media, history, branches, reviews, and deployable truth.
Built for teams with custom sites to maintain.
Surface is for founders, agencies, developers, content teams, and operators who already chose a modern Git-backed website — or used AI to create one — and now need a safe way to keep it alive.
If your site lives in Markdown or MDX, your build runs from Git, and routine content updates still feel too close to code, we would like to learn from you.
