Which assistant lets anyone open a shared chat without an account?

ChatGPT (personal accounts) and Gemini both create links anyone can read. Claude's public links work the same way, but Claude's default is to share with specific people by email, and Team and Enterprise workspaces can't create public links at all.

Do shared links update when the chat continues?

Not automatically, in any of the three. ChatGPT has an Update link option, Claude has Update shared chat, and Gemini requires sharing again, which creates a new link. Workspace links in ChatGPT are the exception and can include later messages.

Which assistant has the fastest full-history export?

Claude emails a JSON export link, usually within minutes, valid for 24 hours. ChatGPT emails a ZIP that can take up to seven days, also with a 24-hour link. Gemini goes through Google Takeout, which takes hours to days, with a 7-day link.

Can any of them export a normal conversation as PDF or Word?

No. ChatGPT downloads Deep Research reports and Canvas documents, Gemini exports single responses to Google Docs, and Claude exports newer artifacts, but an ordinary chat needs printing, copy and paste, or an extension in all three.

How ChatGPT, Claude and Gemini Export Chats

All three assistants can share a conversation by link and hand you your whole history, and all three stop short of saving an ordinary chat as a document. The details differ in ways that matter if you need to keep what you wrote: who can open a link, whether it updates, what's left out, how long an export takes.

Quick answer: ChatGPT, Claude and Gemini all share chats by link and all export your full history, but none of them saves an ordinary conversation as a PDF or Word file. Their defaults differ in three ways:

ChatGPT and Gemini links open for anyone, Claude defaults to sharing with named people.
ChatGPT and Claude links update only when the owner chooses, Gemini needs a new link.
Claude's export arrives in minutes, ChatGPT's in up to seven days, Gemini's through Takeout in hours to days.

	ChatGPT	Claude	Gemini
How to share	Share → Create link	Share, then choose specific people (default) or a public link	Share → Share conversation under any response
Who can open it	Anyone with the link (personal accounts); workspace members only in Business, Enterprise, Edu	Public link: anyone, no account. Specific people: only those emails, signed in	Anyone with the link, and they can reshare it
Plans	All	Public links on Free, Pro and Max; Team and Enterprise can't make them	All, unless a Workspace admin disables sharing
What's included	Conversation, supported images and uploaded files	Conversation and artifacts; attached files excluded (except within an organisation); connector data excluded	Whole conversation, uploaded images, generated Canvas docs, images and videos
Scope	Whole conversation (or a single response)	Whole conversation	Whole conversation, whichever response you click Share under
Later messages	Not included until Update link (workspace links can include them)	Not included until Update shared chat	Not included; share again for a new link
Can viewers continue it	No	No	Yes, Continue this chat copies it to their account (not for Gem chats, under-18s, or without a subscription if the owner has one)
Revoke	Settings → Data controls → Shared links	Unshare from the Share dialog	Settings & help → Your public links
Dies when	Deleted, or the chat is deleted	Unshared or chat deleted	Link deleted, chat deleted or auto-deleted, or chat drops out of pinned and recent

The practical consequences:

A Claude link you receive may need you to be signed in as a named person, which is also why a Claude share link fails more often than the others.
A Gemini link can be continued by strangers, so share only what you'd publish; Gemini share links covers the implications.
A ChatGPT link includes your uploaded files, which the other two mostly don't.

Built-in downloads

	ChatGPT	Claude	Gemini
An ordinary conversation as a file	None	None	None
One response	Copy button (Markdown)	Copy button (Markdown)	Share & export → Export to Docs or Draft in Gmail; tables: Export to Sheets
Research reports	Deep Research: download as PDF, Word or Markdown	Research runs as a normal response; no separate download	Deep Research panel: Export to Docs
Side-panel documents	Canvas: download as PDF, Word or Markdown; code as a source file	Docs, Slides and Design artifacts: Export; older artifacts: copy and download controls	Canvas: Share & export menu with Export to Docs
Files the assistant creates on request	Yes, downloadable from the chat	Yes, with file creation enabled	Yes, within its tools

Gemini is the only one with a built-in path to a Google Doc for any response, and the only one with none to PDF.

ChatGPT is the only one that downloads a research report as Word or Markdown. Claude's export buttons exist only on the newer artifact types.

Everything else needs the extension or another method.

Each section has a walkthrough: ChatGPT, Claude, Gemini.

All three exports are data archives rather than documents. They are the right backup of everything and the wrong way to get one conversation into a readable file.

What this means for keeping your work

If you'll need a chat as a document, plan for an export at the time rather than relying on the link. Links die with the chat in all three; Gemini's die with auto-delete too.
If you share with people outside your organisation, ChatGPT and Gemini links are the frictionless ones; a Claude public link works equally well but has to be chosen deliberately.
If you work in a Team, Enterprise or Workspace account, assume public links and self-service exports may be unavailable, and ask the administrator before you depend on them.
If the content is a report, use the built-in download where one exists (ChatGPT Deep Research, Gemini's Export to Docs) and export the surrounding conversation separately if the reasoning matters.

The extensions described in each section fill the common gap, a conversation as PDF, Word, Google Docs or Markdown, the same way for all three assistants; choosing an exporter explains how to judge that route against the others.
