Item	Type	Severity	Description
scripting	Permission	Critical	This permission allows injection and execution of JavaScript on any webpage. Rated Critical because it can modify page content, steal sensitive data, and inject malicious code into any site the extension has access to.
clipboardRead	Permission	High	This permission allows reading clipboard content. Rated High because it can steal copied passwords, sensitive data, and monitor all content copied to clipboard.
clipboardWrite	Permission	High	This permission allows modification of clipboard content. Rated High because it can inject malicious content into the clipboard, modify copied passwords, and manipulate copied data.
offscreen	Permission	High	This permission creates hidden browser documents with full DOM access. Rated High because it can run background operations invisibly, potentially executing malicious code without user awareness.
storage	Permission	Medium	This permission allows storing data locally in the browser. Rated Medium because it can persist sensitive user data, track user activities over time, and potentially store malicious payloads.
activeTab	Permission	Medium	This permission grants temporary access to the current tab. Rated Medium because it can access current page content when invoked, though limited to user-initiated actions.
https://cleverchecker.com/*	Host	Medium	Host permission — access limited to this URL pattern.
contextMenus	Permission	Low	This permission adds items to browser context menus. Rated Medium because it only modifies right-click menus without access to page content.

About this extension

Check grammar, AI writing, plagiarism and readability, or rewrite text, on any page. Results from cleverchecker.com.

Read the publisher’s full description

Clever Checker puts the whole cleverchecker.com toolkit in a side panel, so you can check writing where you wrote it instead of pasting it into another tab. Select text on any page, right-click, and pick Clever Checker. The panel opens with your selection already in it. - Grammar and spelling, checked as you type, with corrections you apply in one click - AI-writing detection, scored sentence by sentence - Plagiarism, matched against sources on the open web - Readability, word and keyword counts, reading time - Paraphrasing, humanising and summarising, written back into the field you were typing in Nothing is set up and nothing is configured. There is no sign-in step and no server address: open the panel and press the button. Five checks a day are free without an account, and signing in on the website carries a subscription across to the panel. The panel only ever sees text you select or type into it. It does not read the pages you browse, and it carries no analytics. Free: five checks a day, up to 2,000 words, full results from every checker. The four rewriting tools show three quarters of their output and keep the last 25% for Unlimited, which also removes the daily limit and doubles the length.
