About Snapmark

Snapmark is a privacy-focused, open-source tool designed to enhance the way developers and AI users handle screenshots. It allows users to annotate screenshots with callouts, labels, and numbered steps before pasting them into any AI chat or coding environment. Its unique features include auto-blurring of API keys and PII to ensure data privacy, numbered step callouts for clear UI flow explanations, and auto-compression to keep image sizes optimal for token budgets. The tool works seamlessly with popular IDEs like VS Code, simply activated with ⌘⇧A, and can be used anywhere images are pasted. Its 100% local operation and open-source MIT license make it a trustworthy choice for privacy-conscious developers and AI enthusiasts, offering a streamlined way to communicate visual information effectively without compromising sensitive data.
