# Comma vs Claude Artifacts: Publishing an AI-Built Page vs Getting It Reviewed

> Claude can publish an artifact to a public link in one click. What that link does well, what it can't do — private sharing, anchored comments, revisions at a stable URL, agent-side publishing — and when to use each.

# Comma vs Claude Artifacts

## TL;DR

**Claude Artifacts is where the page gets made. Comma is where it gets
reviewed.** An artifact renders beside the chat, and Claude's publish
button turns it into a public link in one click — for a page you simply
want people to see, nothing is faster. Comma picks up where that link
stops: comments anchored to the exact sentence or cell, access that isn't
all-or-nothing, and a URL that keeps pointing at the current version as
the page is regenerated.

They are not competing for the same moment. Most people who use Comma for
AI-built pages made those pages in Claude.

| **Readers comment on it?**      | Yes — anchored to text selections and table cells         | No comment layer for viewers                     |
| **Who can open the link**       | Public, password, invite-only, team or email domain       | Public link (org-only sharing on business plans) |
| **Reader needs an account?**    | No, to read or to comment                                 | No, to read                                      |
| **Regenerate without new link** | Yes — revisions at one URL, diff between any two          | Re-publish from the chat                         |
| **Agent can publish**           | Yes — MCP server and REST API, scoped `comma_sk_…` tokens | Published by a person from claude.ai             |
| **Pages from other tools**      | Yes — Plotly, Jupyter, Playwright, coverage, any HTML     | No — artifacts come from Claude chats            |
| **Price**                       | Free — pay only for routine AI compute                    | Included with Claude plans                       |

## What Claude Artifacts is good at

**Zero-distance publishing.** The page is generated, previewed and
published in the same window, with no copy step and no second tool. For a
calculator, a one-off visual explainer, or a small game you want to post
somewhere, the published artifact is the right answer and Comma would be a
detour.

**Remixing.** A viewer with a Claude account can open a published artifact
and keep building on it in their own chat. That makes artifacts a good
format for sharing a _starting point_ — something you want other people to
fork, not approve.

## What Comma is good at

**Turning "here's a page" into "here's what we decided."** The artifacts
that end up in Comma are usually documents rather than toys — an analysis,
a weekly summary, a migration plan, a design review — and the reason they
were made is to get a decision out of someone. That takes a few things a
public link doesn't give you:

- **Feedback on the specific line.** A reviewer highlights the number
  that looks wrong and pins a thread to it. The next reader sees the
  question in place, not in a Slack thread three days later. See
  [comment on HTML](/comment-on-html).
- **Access that matches the content.** Internal numbers shouldn't sit at
  a public URL. Comma links can be invite-only, password-protected, or
  gated to your team or email domain — [sharing options](/docs/sharing).
- **One URL across versions.** Ask Claude to fix what the reviewers
  flagged, update the same report, and the link you already sent now
  shows the fixed version. Earlier revisions stay recoverable and
  diffable, and open threads carry across.
- **The agent closes the loop.** Over [MCP](/mcp), Claude Code or Claude
  Desktop publishes the page itself, reads the comments on its next run,
  replies in-thread, and marks them resolved when it has made the change —
  [let an agent respond to comments](/agents/let-an-agent-respond-to-comments).

## Where each one wins

### A page you want the internet to see

**Claude Artifacts wins.** One click, public by design, remixable. Use it.

### A document you need signed off

**Comma wins.** Approval needs comments on specific content, a record of
what changed between the version people objected to and the version they
approved, and a link you can restrict. That is the whole product.

### Pages that came from somewhere other than a chat

**Comma wins by default.** Artifacts only hold what Claude generated in a
conversation. The coverage report from CI, the notebook export, the
Playwright run and the agent-written summary all go to the same place in
Comma, reviewed the same way.

### Work that repeats

**Comma wins.** A weekly report regenerated by a
[routine](/features/routines) or a CI job updates one URL every run; the
pinned message in the channel keeps working and last week's discussion
stays attached.

## Moving an artifact into Comma

1. In the artifact, copy the code. If it is a React component rather than
   HTML, ask Claude first: _"Give me this as a single self-contained HTML
   file."_
2. Paste it into [Comma](https://commareports.com/new) — or drop it into
   the free [HTML viewer](/tools/html-viewer) to check it renders, then
   hit **Get a shareable link**.
3. Send the URL. Reviewers can comment without creating an account.

Doing this more than once? Attach the MCP server and let Claude publish
directly — setup for [Claude Code](/mcp/claude-code) and
[Claude Desktop](/agents/share-claude-desktop-output).

## Try Comma

Take the next artifact you were about to screenshot into a thread and
send it as a page people can comment on instead.
