Anthropic has opened its Claude AI assistant to Chrome users through a browser extension available to Claude Pro, Team, and Enterprise subscribers. The extension lets Claude see and interact with live webpages, schedule meetings, organize Google Drive files, and even record custom workflows that the AI can repeat on demand. While the tool offers powerful automation—including handling passwords and multi‑tab tasks—users are cautioned about the breadth of permissions granted, as the AI gains deep access to personal browsing data. Anthropic advises against using the automated features for sensitive activities like banking, underscoring ongoing privacy considerations as AI agents become more integrated into everyday web use.

Anthropic has introduced Claude for Chrome, a browser extension that embeds its Claude AI directly into web pages. The tool can summarize content, analyze products, manage calendars, and even test website features. Launched as a pilot for 1,000 Max‑plan subscribers at $200 per month, the extension includes site‑level permissions and prompts before high‑risk actions to address prompt‑injection vulnerabilities. Safety updates reduced the success rate of malicious instructions from 23.6% to with safeguards that block high‑risk categories. Claude for Chrome joins a growing roster of AI‑powered browsers, including Perplexity’s Comet, Google’s Gemini, Microsoft Edge Copilot, Brave’s Leo, and Opera’s Aria. Read more →

Anthropic’s Claude AI Chrome extension was tested against dozens of attack scenarios, showing a significant success rate when safety mitigations were absent. The company introduced site‑level permissions and user confirmations that cut the success rate, but independent researchers still label the remaining risk as catastrophic. Recent related incidents involving Perplexity’s Comet extension underscore the broader challenge of securing AI agents in browsers. Anthropic plans further testing before broader release, emphasizing the need for stronger protections and user awareness. Read more →
