A growing number of teachers say the Google Lens AI tool is making it almost impossible to stop students from cheating — and they’re seeing the results in their classrooms.

In Los Angeles, high school English teacher Dustin Stevenson noticed something strange: students who had struggled all semester were suddenly acing their exams. At first, he suspected traditional cheating — until one student showed him a hidden feature built into Google Chrome.

By clicking the Lens icon in the toolbar, students can open a movable bubble that lets them highlight part of a test question. Instantly, a sidebar appears with an AI-generated explanation, answer, or summary — no typing required.

“I couldn’t believe it,” Stevenson said. “It’s hard enough to teach in the age of AI, and now we have to compete with Google’s own tools.”

How the Google Lens AI Tool Turned Into a Shortcut

The Google Lens AI tool was originally designed to help users identify objects or translate text through their camera. But as Google integrated more advanced AI into Chrome, Lens became a powerful — and potentially dangerous — resource for students.

Millions of California students now use Google Chromebooks, many of which were distributed during the pandemic. These devices, with Lens enabled by default, have become central to digital classrooms — and, some say, a gateway to academic dishonesty.

Teacher William Heuisler said he saw the writing on the wall:

“After COVID, Chromebooks were a terrible idea in my classroom,” he said. “Now with AI, it’s even worse. Students don’t need to think — they just click and get the answer.”

Heuisler decided to go old-school: no laptops, no phones, and everything on paper. “It’s more work,” he said, “but it forces students to actually think.”

AI Tools Are Affecting Student Learning

Research supports teachers’ concerns. A Massachusetts Institute of Technology study titled “Your Brain on ChatGPT” found that students who used AI tools to write essays showed less cognitive activity and produced weaker writing overall.

Another nationwide survey by the Center for Democracy and Technology found that 70% of teachers doubt whether students’ work is their own, and 75% worry that AI is eroding critical skills like writing, reading comprehension, and problem-solving.

Despite these concerns, 85% of teachers and students now use AI in some form — whether for lesson planning, grading, or research.

Lack of AI Rules Leaves Schools Divided

One major issue is that there’s no clear rulebook for AI use in schools. The California Department of Education provides guidelines for teachers, but no strict enforcement policies.

Some teachers, like Hillary Freeman at Piedmont High School, have created their own. “If students use AI to write a paper, they get a zero,” she said. She allows AI tools only for summarizing complex concepts or generating practice questions.

But she admits catching cheaters is exhausting. “It’s not sustainable,” Freeman said. “I spend hours checking version histories and using plagiarism tools that sometimes flag innocent students.”

According to the RAND Corporation, only 34% of teachers say their schools have consistent AI policies. Without clear standards, confusion reigns — and students are left to decide for themselves what counts as cheating.

Google’s Response: Ethics, Literacy, and Control

Google has defended the Google Lens AI tool, saying it’s meant to “enhance learning” — not replace it. The company has invested over $40 million in AI literacy programs and encourages educators to teach responsible use of its products.

“Students value tools that help them learn visually,” said Google spokesperson Craig Ewer. “We’re working closely with educators to ensure the Google Lens AI tool supports learning and not misuse.”

However, districts can disable Lens on school-issued Chromebooks if they choose. The Los Angeles Unified School District has opted to keep it active — but only for students who complete a digital literacy lesson and agree to follow the district’s academic integrity rules.

“As new digital tools evolve, we continuously evaluate how they’re used,” a district spokesperson said.

A Lesson in Responsibility

For teachers like Stevenson, who discovered Lens being used for cheating, the situation feels like déjà vu. “We’re trying to build integrity and critical thinking,” he said. “Then Google drops an AI button that undoes it all.”

He recently noticed the Lens shortcut disappearing from student Chromebooks — likely a temporary fix after his report to the district.

“It’s encouraging,” he said. “But it also shows how chaotic the AI rollout has been. Teachers plan lessons for months — and one update from Google can completely change the classroom.”
