Chrome Permission Audit

clipboardRead vs clipboardWrite permissions in AI Chrome extensions.

Why do some AI extensions ask to 'Read data you copy and paste'? Learn the difference between one-click copy buttons (clipboardWrite) and background clipboard monitoring (clipboardRead).

Best fit

Best for privacy-conscious users who want to protect password managers and copied secrets from browser extensions.

Legitimate uses vs. red flags
What to verify before granting this permission to an AI browser tool.

Legitimate AI reading uses

  • `clipboardWrite`: Allowing a 'Copy Answer' button inside an AI overlay to copy the response to your clipboard when clicked
  • `clipboardRead`: Only needed by dedicated clipboard managers or extensions triggered specifically to translate clipboard contents

Red flags to watch for

  • An AI reading extension requesting `clipboardRead` when it already reads selected text via `window.getSelection()`
  • Reading the clipboard on focus changes—which can expose passwords copied from 1Password or Bitwarden
How Vezz me handles this: Vezz me does NOT request `clipboardRead`. It reads your highlighted webpage text via standard DOM selection when you press your shortcut, and only writes to your clipboard when you explicitly click the Copy button on an answer.
Step-by-step workflow

How to run this workflow in place.

1

Protect your system clipboard

Your clipboard frequently holds passwords, API keys, 2FA codes, and private messages from desktop apps outside the browser.

2

Prefer selection-based reading over clipboard reading

In-page reading tools should use `window.getSelection()` on the webpage—not `clipboardRead`—so you never have to press Ctrl+C just to ask a question.

3

Allow clipboardWrite only on explicit clicks

Modern browsers allow copying text inside a user-click handler (`navigator.clipboard.writeText`) without needing broad background clipboard access.

Key details

Why this approach works better than switching tabs.

Why clipboardRead is a high-sensitivity permission
Unlike DOM selection—which is confined to the webpage you are viewing—the system clipboard is shared across every application on your computer.
  • If you copy an SSH key from Terminal or a password from a desktop vault, `clipboardRead` can potentially access it
  • Highlighting text on a webpage does NOT require clipboard access
  • Vezz me eliminates copy-paste entirely: you highlight text and press Ctrl+Shift+X without touching your clipboard
How Vezz me's one-click Copy button works safely
When Vezz me displays an explanation on screen, you can click Copy to save the answer into your notes.
  • Uses standard user-initiated clipboard write when you click the Copy button
  • Never reads or monitors what is currently on your clipboard
  • Keeps your existing clipboard untouched until you explicitly choose to copy an AI response
Frequently asked questions

Common questions about chrome permission audit.

Does highlighting text on a webpage use the clipboard?

No. Selecting text with your mouse or keyboard highlights it in the browser DOM (`window.getSelection()`). Your system clipboard is only used if you press Ctrl+C / Cmd+C. Vezz me works directly from your highlight without modifying your clipboard.

Does Vezz me ask for clipboardRead permission?

No. Vezz me never reads your clipboard.
