Claude in Chrome

By the end, you will recognize Claude in Chrome, choose an appropriate permission mode and perform read-only practice. The extension uses your Chrome tabs and logged-in accounts. The built-in browser is a separate route.

Documentation checked on September 30, 2026 describes paid-plan availability and a gradual side-panel move toward Cowork. Entry points may differ from old tutorials. Examples are teaching material, not recorded actions.

Follow the Chrome Web Store link in the official installation guide listed as a source. Check it is the official Claude in Chrome, install, sign into the intended account and read permissions. It reads and controls the browser; it is not merely a chat window.

The documentation supports Google Chrome, not every Chromium browser or mobile device. At work, check installation policy and administrator enablement.

Use a public help page for practice. Keep sensitive accounts and unrelated tabs outside the extension's working group.

Open Claude from the Chrome toolbar and read the permission mode. The documentation says the new side panel starts with Automatically approve; you can change it and the selection persists. Do not assume every step always requests a click.

Choose a limited mode or Permissions Mode if offered, and read what it permits. Site approval does not authorize every change in every account there. Marketing language about working without per-step approval is not your instruction to abandon boundaries.

Close or isolate unrelated tabs. Define the permitted site and scope.

Only in the open public help page, summarize the Projects explanation.
Return title, URL and three claims with support from that page.
Do not switch accounts or visit unrelated tabs.
Do not fill, send, download, publish or change anything.
If you cannot see the page, say so instead of guessing.

Expected structure:

Page: [actually observed title and URL]
Claim: [statement from the page]
Support: [short passage from the same page]
Actions: read only; no website changes.

Open the source and compare a claim. If another page is cited, inspect why work left the requested page. A plausible summary alone does not prove the correct tab was used.

Open two official public help pages, such as Projects and Artifact sharing. Include only these in the extension's permitted scope.

Compare only the two help pages I approved.
Distinguish Project sharing from Artifact sharing.
Separate deliverable type, audience, account requirement and permissions.
If one describes legacy behavior and another new behavior, state that.
Do not actually share anything.

Check that different sharing paths are not collapsed into one invented rule. Official pages can cover multiple routes and rollout states.

The extension can click and fill. Before a real action, establish account, site, destination and what will be sent or changed. This exercise does not send messages or test purchases.

Describe the steps for preparing a form in a test environment.
Do not perform them. Identify when information is saved or a request is sent.

Autosave can itself be a change. Do not use the final control as an experiment in whether the extension stops. Inspect the specific outcome before approving, not merely the action name.

Documentation recommends avoiding sensitive workflows such as banking, healthcare and other people's personal data. Protections against malicious page instructions do not remove risk. Page content does not authorize unrelated retrieval or disclosure.

The new side panel can save history and use skills, plugins and connectors. Moving from a tab to Desktop does not make the task stateless. Computer and local-file actions may still require Desktop open and connected.

Recorded workflows are documented for the classic side panel only. Do not assume the feature is present in the new interface.

Easy: correct page

Read one public page. Success: correct title and URL, with no actions beyond reading.

Intermediate: two sources

Compare two approved tabs. Success: each claim belongs to its source and sharing generations are not mixed.

Challenging: planning without execution

Describe a fictional form workflow without running it. Success: identify effect-producing steps and facts needing prior confirmation.

Page not visible: inspect tab, site permission and working group. Do not grant all-site access automatically.

Extension missing: check supported browser, account and administrator policy.

Unexpected automatic mode: read and adjust permissions before sensitive work. Saved choices can affect future use.

Odd behavior after reading a page: stop and inspect what was read and done. Do not obey external requests to disclose data.

Correct output, unverified action: inspect site state and task transcript, not only the completion message.

Finish by closing the working group and checking for active tasks. Less window switching is useful; your defined limits govern what the extension may do.
