You've got the prototype looking right in Claude Design, and the next person who needs to see it is a client. Anthropic's launch announcement for Claude Design (17 April 2026) describes sharing for designs as organisation-scoped, and Anthropic's help centre says plainly that people without a Claude account can't open a shared artifact, even with the link. For a teammate that's no obstacle. For a client who has never used Claude, it's a sign-up screen standing between them and your work. The way round it is to send a file that came out of Claude instead of a share that lives inside it: export the design, put it behind a private link, and your client opens it in their browser like any other web page.

Export the design as HTML. In the Design export we tested, the fonts were embedded in the file and the page made no requests to anything outside it, so it looked the same on a stranger's network as it did in Claude. It was also a fixed 1440-pixel artboard with no mobile setting, which means a phone shows it with sideways scrolling. Our prompt asked for a desktop layout, so yours may behave differently, but if you know your client will open it on a phone, export the PDF instead. Anthropic lists more export formats than those two; HTML and PDF are the ones we've tried.
Drop the file in and you get a private link. The HTML we exported was 370 KB, comfortably inside the 3 MB you can upload without an account. That link lasts 7 days and can take a password. A free account lets you change that password later, and keep one link from expiring. The address ends in 32 random characters and carries a no-index tag, so an unreleased design stays out of search, and your client needs nothing more than the link to open it. If the design has clickable flows, click through your own link once before you send it: we've checked how an exported layout renders, not every interaction a prototype can contain.
Designs go through rounds. When you revise in Claude Design, export again and replace the file from your dashboard: the address stays the same, so the link your client already has opens the new version. Turn on Review and they can pin a comment to the exact spot they mean, with no account, rather than describing it in an email. Review is free on every plan, and on Studio you can export the comment thread as markdown and paste it back into Claude for the next round.
Not according to Anthropic. Their launch announcement describes design sharing as organisation-scoped, and their help centre says people without a Claude account can't open a shared artifact, even with the link. On Team and Enterprise plans, sharing outside the organisation is also off unless an owner turns it on. That's a reasonable design for work that lives inside an account. It means that for a client outside your organisation, the design has to leave Claude as a file. It's Anthropic's product and their wording to change, so check their current pages before relying on this.
No. Use Claude's own sharing. It's built for exactly that case: nothing to export, nothing to keep in sync, and the design they see is the one you're working on. Exporting a file is for the reader who sits outside your organisation and has no reason to create a Claude account to look at your work.
Go by the screen your client will use. On a laptop, the HTML is the better experience: in our test it kept its embedded fonts and loaded nothing from outside the file. On a phone, the HTML we exported was a fixed 1440-pixel artboard that scrolled sideways, so the PDF is easier to read there. A PDF is uploaded exactly as exported and opens in a viewer page in the browser.
We don't take .pptx files, so for a PowerPoint export the answer is no: send the HTML or the PDF instead, or attach the .pptx itself if your client actually wants to edit slides. We do accept ZIP uploads in general, but we haven't tested a ZIP export from Claude Design yet, so we can't tell you how it comes out. The HTML route is the one we've checked.
No. The file you uploaded is a snapshot of the moment you exported it. Export again and replace the file from your dashboard, and the link stays the same, so your client's bookmark opens the new version. Replacing needs an account: an upload made without one has nobody attached to it who could replace it later.
Yes, if you turn Review on for that document. Whoever opens the link can click the part of the design they're reacting to and type a comment there, with no account and nothing to install. You work through the notes on the page and mark them resolved. Review costs nothing on any plan; exporting the whole thread as markdown is a Studio feature.
