Claude Artifacts place substantial standalone content in a separate working area. Anthropic lists documents, code, single-page websites, SVGs, diagrams and interactive React components as examples. The useful distinction is not the visual pane; it is that the output can be revised and used as an object of its own.

Specify behavior before appearance

Build a decision table for comparing two vendors. Use this fictional input:

  • Cedar: CSV export; one-business-day support response; scheduled export not stated.
  • Harbor: weekly scheduled CSV; weekday live chat; response time not stated.

Request an artifact with these requirements:

Create a standalone decision table artifact.
Rows: scheduled export, export format, support availability, response commitment.
Columns: criterion, Cedar, Harbor, evidence status, reviewer note.
Evidence status must be Supported, Not stated or Conflict.
Do not calculate an overall winner.
Add a text filter for evidence status and a Reset button.
Keep the original vendor statements visible below the table.

This specification states the data, allowed statuses and interactions. “Make a vendor dashboard” does not.

Test the artifact as a small product

Check the initial state before asking for visual changes:

Test Expected result
Open artifact Four rows are visible
Filter “Not stated” Only missing-evidence rows remain
Reset All four rows return
Inspect Cedar scheduled export Status is “Not stated”
Inspect original statements Text matches the supplied input

A polished artifact fails if it labels Cedar “manual only,” hides the source text or loses rows after Reset.

Revise one requirement at a time

Point to the exact behavior and preserve the rest: “Change the filter so Reset restores all rows. Do not alter the data or status labels.” Anthropic’s help page notes that artifact versions can be revisited; use versions as a review trail, not as proof that the newest version is correct.

Before sharing or exporting, test the artifact again and remove any material you were not allowed to publish. For reusable sources and instructions across several chats, use Claude Projects. For a one-off document comparison, start with the Claude walkthrough. Keep the original specification, the observed failure and the revised instruction together. That record explains why the change was made and makes it easier to notice when a visual improvement breaks required behavior.

Questions about Claude Artifacts

When should I use an Artifact instead of a normal response?

Use an Artifact when the output needs to stand on its own, be revised repeatedly or behave like a small document, diagram or interface. A short answer that will not be reused does not need that extra structure.

Does a working preview prove the information is correct?

No. Test the behavior and verify every important label, number and claim against the specification and source material. Visual polish is a separate check.

What should I save before revising an Artifact?

Save the current specification, a case that passes and the case that failed. After the revision, rerun both so a local fix does not hide a regression.
