Websites at the speed of marketing

Subtext is the full-code website platform for marketing teams. Host, ship, edit, and analyze your site with the AI you already use, on real code you never have to read.

Closer to the source

LLMs are great at writing code. So great that most developers have stopped reading it. What’s left is the real work: knowing what to build and when it’s right. That’s what marketers do best. Subtext gives you everything else.

  • Work with your AI

    Subtext connects to the AI you already use and gives it everything you need to work on your site: the codebase, live previews, comments, and more.

  • Stay on brand

    Design new components and pages the minute you need them. Your AI sees your entire codebase, so whatever you build stays consistent with the rest of your site.

  • Ship anything

    Your site is real code, so there are no limits to what you can build. Add calculators, interactive demos, or custom integrations without plugins or workarounds.

  • Batteries included

    Hosting, analytics, live previews, publishing, and security, all in one place. Everything you’d get from a page builder, without the page builder.

AI was trained for this

Subtext sites are built with plain HTML, CSS, and JavaScript, the languages LLMs are trained on. There’s no proprietary format for your AI to work around, and nothing locking you in: your site lives in a standard git repo you can take and rehost anytime.

Break your site in private

Every idea starts with a prism: a live, private copy of your site where you can see changes, share with your team, and iterate until it’s perfect. Ready to go live? Just one click. Missed something? Roll it back in about a minute.

  1. Watch your agent work

    See every change your AI makes as it happens, on a live preview of your real site. Check it on desktop and mobile, and steer as you go.

  2. Make big changes and small fixes

    Give every project its own prism, from big experiments to quick edits to pages waiting on approval. When you publish, only that prism’s changes go live, so your redesign doesn’t hold up a typo fix.

  3. Collaborate on the page

    Send a prism to your team or clients for feedback. They can see the live preview and click anything to comment. Once they’re done, your agent can work through the notes for you to review.

The boring stuff, handled

  • Built-in analytics

    Everything you’d use Google Analytics for, without the cookies or the setup. Channels, UTMs, page speed, custom events, AI traffic, and more.

  • Ready for scale

    Every site is served from Cloudflare’s global edge network. No servers to manage, nothing to maintain, and no slowdowns when traffic spikes.

  • Fast by default

    Subtext sites are fully static and cached at the edge, so pages load almost instantly.

  • Short links

    Create links on your own domain that point anywhere, with UTMs and analytics built in.

  • Native forms

    Multi-step, conditional, fully on brand. Any form you need, without a 3rd-party service.

  • Secure by default

    No plugins to patch, no database to hack, no updates to chase.

  • SEO and AEO

    Keep your rankings and control over everything search engines and AI crawlers look for.

  • No lock-in

    Built on Astro, an open-source framework that any developer or agency can edit.

Bring your site with you

Point your AI at your current site and you can migrate it to Subtext in a few prompts. Same design, same pages, same URLs. Connect your domain and your search rankings come with you. The work your designer put in is what keeps your AI on brand from here on.

Step-by-step guides for your platform

Or just ask your AI to use the migration skills that come built-in to Subtext.

Frequently asked questions

Do I need to know how to code?

No. Your AI reads and writes the code. You describe what you want, watch the changes on a live preview, and publish when it’s right.

Which AI tools work with Subtext?

Subtext works with Claude, ChatGPT, and any AI tool that supports MCP. You connect it once, and your AI can work on your site from the same chat you already use.

Is there a built-in AI?

No, by design. Your AI already knows your brand, has been approved by your company, and keeps getting better on its own. Subtext gives it everything it needs to work on your site instead of asking you to learn a new one.

How is this different from Framer or Webflow, now that they have AI too?

Page builders store your site in their own format, so their AI tools have to work through it. Subtext sites are real code, the HTML, CSS, and JavaScript your AI was trained on. That means it can design new components, add custom features, and keep everything on brand, without a builder’s limits.

Is this vibe coding?

No. Vibe coding tools generate a site from a prompt. Subtext starts from your professionally designed site and gives you the workflow developers use: every change in a private preview, reviewed by your team, and published only when you say so.

Is there a CMS? How does my team update content?

There’s no CMS to set up or maintain. Your AI is how you edit the site, whether it’s a typo fix or a new page. Teammates can leave comments right on a prism, and your AI can work through them.

What if my AI breaks something?

Every change happens in a prism, a private copy of your site, so nothing reaches visitors until an editor hits publish. Your AI is set up to never publish without permission. And if something slips through, you can roll back in about a minute.

Who owns the site? Can I leave?

You do. Your site is a standard Astro project in a git repo your company owns. Any developer or agency can work on it, and you can take it with you anytime.

What can my AI access, and is my content used for training?

Your AI can only reach the workspaces you approve when you connect it. Subtext doesn’t include an AI, so we never train on your content. What your AI provider does with your conversations follows their own data policy and your plan’s settings.

Will I lose my SEO if I switch?

No. Your pages keep the same URLs, redirects carry over, and your design and content stay the same. Connect your domain and your rankings come with you.

What happens to my domain and DNS?

You keep your domain and your existing nameservers. Point your domain at Subtext, and SSL certificates are handled automatically.

Who on my team can make changes or publish?

Everyone in your workspace can view prisms and leave comments, and editors can also make changes and publish. Seats are unlimited, so you can invite your whole team. Need feedback from a client without an account? Share a password-protected prism.
