# 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.

## Technical Permission Audit

- **Manifest Key:** `clipboardRead / clipboardWrite`
- **Chrome Install Warning:** "Read data you copy and paste" (for clipboardRead)
- **Risk Level:** Medium

```json
{
  "manifest_version": 3,
  "permissions": ["clipboardRead", "clipboardWrite"]
}
```

### Legitimate 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

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.

## 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

### 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.
