Multi-model artifacts

Artifacts that work with every AI.

Claude, ChatGPT and Gemini each make artifacts, and each keeps them inside its own app. Spacesheep gives an artifact a link of its own. You pick who can open it, they comment on it, and any AI can keep improving it.

Free to start. Private until you share it.

What it means

Multi-model artifacts: one page, any AI.

A multi-model artifact is a page that doesn’t belong to the AI that made it. Claude makes it, ChatGPT changes it, Gemini reads it, all at the same link, with every version kept. It is also called a model-agnostic, provider-agnostic or cross-model artifact.

  1. 1

    Any AI publishes it

    From Claude, ChatGPT, Cursor, Codex, Claude Code or Gemini CLI, through one connector.

  2. 2

    It lives at one link

    Plain HTML with every version kept. The history says which AI wrote each one.

  3. 3

    Any other AI picks it up

    Give it the link. It reads the current version and writes the next one. No copy-paste, no handoff document.

Why move it

A built-in artifact belongs to its AI.

Claude, ChatGPT and Gemini can each share what they make, and they keep getting better at it. But only that AI can change it, and readers come in through that AI’s door.

What you get

Everything a real page has.

Any AI, one page

Claude makes it, ChatGPT fixes a number, Cursor adds a chart. Same link, one history, and you can see which AI wrote each version.

You decide who opens it

Only you, the people you name, your team, anyone signed in, or anyone with the link. Change it whenever you like.

Comments on the exact spot

Readers pin a comment on a line or a chart. Write @spacesheep in one, and its agent answers and fixes the page right there.

Every version kept

Each change is a version you can open, compare and restore. Nothing an AI rewrites is ever lost.

Know who read it

Views, the people who opened it, how long they stayed, and what they reacted to.

Pages that do things

RSVPs, polls, forms, booking pages, shared task lists and dashboards over live data. Storage is built in, with no server to run.

Try it

Your next artifact, a link in a minute.

  1. 1

    Connect your AI

    One click for Claude or Cursor. ChatGPT, Grok, Codex and the rest take a minute on the setup page.

  2. 2

    Say it under the artifact

    Right below what your AI made, or with a fresh ask:

    Publish this as a spacesheep page and send me the link.
  3. 3

    Pick who sees it

    Private to start. Share it with names, your team or everyone, and send the link. They can comment from any phone.

Questions

Asked often.

What is an AI artifact?

An artifact is something an AI makes for you to look at or use, rather than read as a reply: a report, a chart, a slide deck, a calculator, a form, a small app or a game. Claude calls them artifacts, ChatGPT calls them Sites, and Gemini calls them canvases. On spacesheep each one is a page with its own link.

What is a multi-model artifact?

An artifact that doesn't belong to the AI that made it, also called a model-agnostic, provider-agnostic or cross-model artifact. A page Claude made can be changed by ChatGPT, Gemini, Cursor or Codex the next day, at the same link, with every version kept. You can switch models without leaving your work behind.

Can I share a Claude artifact with only some people?

Yes. Claude’s own email invites are in beta on its paid plans. With spacesheep, ask Claude to publish the artifact, then choose who can open it, on the free plan too: only you, the people you name, your team, anyone signed in, or anyone with the link. You can change it at any time and see who opened it.

Can I move a Claude artifact to ChatGPT, or the other way?

You don't need to move it. Publish it with spacesheep from Claude, then give ChatGPT the link and say what to change: it edits the same page, and the version history shows which AI made each change. No copying, and no handoff document to explain it. It works in any direction, with any AI connected to spacesheep.

Which AI tools does it work with?

Anything that speaks MCP: Claude (web, desktop and mobile), Claude Code, ChatGPT, Grok, Codex, Cursor, Windsurf, Antigravity and Gemini CLI. You can also make a page right on spacesheep, with no AI of your own connected.

Is it free?

Yes. The free plan publishes and shares pages with comments and version history. Pro adds bigger sites, longer pages and daily backups. See the plans page for the details.

Will my artifact show up in Google?

Only if you want it to. A page starts private, and even a page open to anyone stays out of search engines until you tick Listed.

Can an artifact store data?

Yes. A page can keep what people enter, like RSVPs, poll votes, form answers or a shared task list, and everyone it is shared with sees the same data. There is no server to run.
