Why does my phone download the file instead of showing it?

A Claude artifact you save from a chat is a local .html file, and most phones treat that as a download rather than a page to render. There's no address to open it at, so it lands in your Files or Downloads and sits there. A Drafty canvas lives at a real URL, so the phone opens it like any other web page.

Can I comment from my phone?

Yes. Tap any element on the canvas — a heading, paragraph, image, or code block — and leave a comment pinned to it. You can comment as a named guest with no signup, or sign in with a magic code to claim your comments to an account.

Does it work on iPhone and Android?

A Drafty link opens in any browser, so it works on iPhone, Android, and desktop alike. There's nothing to install to read or comment on a canvas.

Does the link stay the same when I update the artifact?

Yes. Each `drafty canvas push` saves a new version at the same link, so the URL you sent keeps working. Comments stay anchored to their elements across versions.

How do I view a Claude artifact on my phone?

Quick answer

Phones usually can't open a raw .html file you download from a chat. Turn it into a Drafty link with `drafty canvas push`, and it opens in any mobile browser. You can read it and leave comments from your phone too.

To view a Claude artifact on your phone, turn the .html file into a Drafty link. A raw file you download from a chat usually won't open on a phone, but a Drafty canvas lives at a real URL that any mobile browser can load.

Push the file once and you get a link like drafty.im/canvas/<slug>. Open it on your phone to read the artifact full-screen, and tap any element to leave a comment — no app to install.

Why a downloaded .html will not open on a phone

When you save an artifact from a chat, you get a local .html file. Phones treat that as a download, not a page to render. It lands in Files or Downloads with no address to open it at, so tapping it does nothing useful.

A Drafty canvas fixes this by hosting the file at a URL. There's nothing to download — the phone loads it the same way it loads any web page.

The fix: a Drafty link

Publish the artifact as a canvas with the Drafty CLI or the Claude Code plugin:

Save the artifact as a file, for example report.html.
Run drafty canvas push report.html. Drafty reads the file as HTML, hosts it, and prints the link.
Send yourself the link, or share it with anyone else.

If you don't have the CLI yet, you can ask Claude to "drafty this" file, or get the CLI. An HTML canvas keeps the artifact's own styles and renders as a full standalone page.

Open and read it on mobile

Open the drafty.im/canvas/<slug> link in any mobile browser. The canvas fills the screen and scrolls like a normal page. If you push an updated version later, the link stays the same, so the one you sent keeps working.

Comment on mobile

You can give feedback right from your phone. Tap any element — a heading, paragraph, list item, image, table, or code block — and a threaded comment pins to that exact spot. You can comment as a named guest with no signup, or sign in with a magic code to claim your comments to an account.
