Anthropic's Claude chatbot can now write and run JavaScript code. TechCrunch: Today, Anthropic launched a new analysis tool that helps Claude respond with what the company describes as "mathematically precise and reproducible answers." With the tool enabled -- it's currently in preview -- Claude can perform calculations and analyze data from files like spreadsheets and PDFs, rendering the results as interactive visualizations. "Think of the analysis tool as a built-in code sandbox, where Claude can do complex math, analyze data, and iterate on different ideas before sharing an answer," Anthropic wrote in a blog post. "Instead of relying on abstract analysis alone, it can systematically process your data -- cleaning, exploring, and analyzing it step-by-step until it reaches the correct result." Anthropic gives a few examples of where this might be useful. For instance, a product manager could upload sales data and ask Claude for country-specific performance analysis, while an engineer could give Claude monthly financial data and have it create a dashboard highlighting key trends.
