The share button inside Claude, Gemini and ChatGPT, compared

Every AI that writes a page now has a way to show it to someone. Claude has Publish, Gemini has Share and export, and ChatGPT had Canvas until this summer. If you have ever finished a page in one of them and wondered whether you still need to host it anywhere, this is the answer, checked against each vendor’s own documentation in September 2026.

The short version: all three can produce a link a stranger can open. None of them can produce a link a stranger can reply to.

Claude: Publish

On a Free, Pro or Max plan, an artifact has a Publish button that produces a public link. Anyone can open it without signing up and interact with it; if the artifact calls Claude itself, viewers are asked to sign in before those parts work. Team and Enterprise plans cannot publish publicly at all: artifacts there are shared within the organization only.

What a viewer can do with a published artifact is look at it and, if they want, copy its code into a chat of their own. There is no comment feature and no way to suggest a change. Claude Code’s artifacts, a separate product, do have comments, and they are limited to people inside the same Team or Enterprise organization; a publicly shared one cannot be commented on.

Two more things worth knowing before you hand a client a published link. There is no password option, and public artifact links have turned up in Google search results.

Gemini: Share and export

A Gemini Canvas app can be shared with Share and export, then Copy link. Anyone with the link can open the app and use it, and Google’s documentation says they can view and edit the data associated with it, which means the app’s state, not its code.

The link opens on gemini.google.com only: it does not open in the Gemini mobile app, and it is not available to under-18 accounts. There is no commenting, no password, and no custom domain. Google documents that shared chats are snapshots that do not change after sharing; whether an app link follows your later edits is not documented.

ChatGPT: Canvas, retired

Canvas was removed from ChatGPT’s current models in May 2026, and legacy access ended in August. ChatGPT still writes a complete HTML file on request; it simply has nowhere to put it. The file arrives as a download or a code block, which is where why HTML files don’t open from email comes in.

What all three have in common

They treat the page as finished. The share link is a way to show, and showing is enough when the page is done. Most AI output is not done: it is a draft that exists to get a reaction, and the reaction currently comes back as a screenshot with an arrow drawn on it.

Hosting the same file yourself changes what the link is for. On FileShare Pro the page opens on any phone or browser, and anyone holding the link can comment after typing a name, pin the comment to the button or paragraph they mean, or suggest an edit you approve or reject. Replace the file and the link stays the same, with the thread attached. And because the connector works from inside ChatGPT and Claude, the AI that wrote the page can publish and update it without leaving the chat.

• ✓Claude Publish: public link, no comments, no password, not on Team or Enterprise.
• ✓Gemini share: link opens in Gemini on the web only, no comments, no password.
• ✓ChatGPT: no hosting since Canvas was retired; save the file and host it.
• ✓FileShare Pro: host the file, get comments and suggested edits on the page, keep the link across versions. See the full comparison.
