The company, once popular among students, said its “strategic” options could include a sale. Chegg blamed Google’s AI summaries for taking away traffic.

Online education company Chegg filed a lawsuit on February 24th against Google claiming that the company’s AI-generated summaries of search results have hurt its traffic and revenue, Reuters reports.

Chegg is only the latest publisher to take issue with Google’s efforts to inject Google Search with AI. A number of news outlets claim they’ve seen an impact on traffic from Google’s AI summaries in search, which draw from sources around the web to answer Google Search user queries.

Chegg is suing Google parent Alphabet over claims the search engine’s artificial intelligence summary tool has hit its revenues, leading the US-listed educational technology group to weigh up a sale of the business.

If you use Google Search, you’ve no doubt noticed that results now often begin with an “AI Overview.” The pop-up is a major change to one of the world’s most popular tech products; Google surfaces a response to many questions without making you click into other websites.

One company is the educational company Chegg, and it’s suing Google over its AI overviews. Most people know this, but here’s a refresher. Last year, Google released AI Overviews. This is a tool that puts AI-generated overviews of what you searched for on top of its search results.
