This Study's List of Invasive AI Extensions: Are Yours Safe? - Routinova

Sarah, a self-proclaimed productivity wizard, reveled in her browser's efficiency. Every tab, every shortcut, every AI-powered extension felt like a superpower. She used an AI writing assistant for emails, a meeting transcriber for calls, and even a clever tool that summarized articles on the fly. Life was optimized. Until a peculiar email landed in her inbox--an offer for a niche product she'd only ever typed into a private document. A chill ran down her spine. How did they know? That's when she started wondering just how much these digital helpers were truly 'helping' themselves to her data.

Sarah's unsettling discovery isn't an isolated incident. A recent deep dive by researchers at the data removal service Incogni confirms what many of us quietly suspect: many AI browser extensions, while incredibly useful, are also incredibly invasive (Incogni, 2024). Their investigation, which analyzed extensions in the Chrome Web Store, highlights this study's list of the most privacy-hungry AI tools, including popular names like Grammarly and Quillbot, which many of us rely on daily.

The sheer volume and type of data scooped up by these extensions are eye-opening. Incogni found that nearly a third of all AI-powered extensions are silently collecting website content--everything from the text you read to the images you view and the hyperlinks you click. But that's just the start. More than 29% of these tools harvest personally identifiable information (PII) like your name, address, email, and even identification numbers. Beyond PII, they're often logging your user activity, authentication details, personal communications, location data, financial information, web history, and even sensitive health insights. Think about it: an AI Recipe Creator extension might see your grocery lists, an AI Travel Planner could track your destinations, and an AI Meeting Notetaker could access your confidential work discussions.

It turns out that some of the most data-hungry culprits fall into categories you might not expect. Programming and mathematical aids, such as Classology AI and StudyX, often top this study's list of privacy risks. Meeting assistants and audio transcribers follow closely behind, given their access to sensitive conversations. Even widely used writing and personal assistants, despite their convenience, frequently appear on this study's list of extensions with significant privacy concerns.

Incogni didn't just stop at categories; they assigned 'privacy-invasiveness' scores to the most downloaded AI extensions. These scores are a stark combination of the data collected and the general and sensitive permissions required. Here's a snapshot of some high-scorers:

  1. Grammarly: AI Writing Assistant and Grammar Checker App (tied for #1)
  2. Quillbot: AI Writing and Grammar Checker Tool (tied for #1)
  3. Sider: Chat with all AI (tied for #3)
  4. AI Grammar Checker & Paraphraser -- LanguageTool (tied for #3)
  5. Google Translate (tied for #4)
  6. WPS PDF -- Read, Edit, Fill, Convert, and AI Chat PDF with Ease (tied for #4)
  7. Monica: All-in-One AI Assist (tied for #4)
  8. AI Chat for Google (tied for #4)
  9. Immersive Translate -- Translate Web & PDF
  10. ChatGPT search

What makes the top contenders so invasive? Grammarly and Quillbot, for instance, don't just grab your PII and website content; they also pinpoint your location via IP address and GPS coordinates. Grammarly goes further, monitoring user activity through network tracking, clicks, mouse movements, and even keystroke logging. While both demand sensitive permissions--like injecting code and accessing active browser tabs--it's worth noting that Incogni found their risk of malicious use to be relatively low. The concern lies more in the sheer volume of data they can access, not necessarily that they will use it maliciously (Tech Insights Review, 2023).

So, what does this mean for you, the savvy internet user? AI browser extensions aren't inherently evil. Many offer genuine convenience and boost productivity. But here's the catch: you need to be acutely aware of what information they're collecting and the permissions they demand. The most common sensitive permissions involve 'scripting,' which lets an extension interact with pages as you browse, and 'activeTab,' allowing it to read or modify the current page.

Think about it this way: when you add an extension, you're essentially handing over keys to parts of your digital life. If those keys aren't strictly necessary for the extension's core function, or if the justification feels flimsy, you could be exposing your data or device to unnecessary risk (Digital Guardian, 2024). Incogni's findings reinforce a critical truth: we each have to weigh the convenience of these powerful tools against the privacy we're willing to sacrifice. Sometimes, this study's list of warnings is a necessary wake-up call.
