What ChartHawk does
ChartHawk lets you upload chart images and receive an AI-powered explanation of what the chart shows, its limitations, and common misreadings.

What happens to your uploaded images
Images you upload are sent to Anthropic's Claude API for analysis. They are also stored in your ChartHawk account so you can revisit previous analyses. By using ChartHawk you agree to Anthropic's usage policies.
