What is VEXI?

This tool installs through a single command and runs across major operating systems while respecting project ignore rules during codebase analysis. It compresses context to avoid repetitive explanations and can execute build commands for multiple programming languages directly from interactions. VEXI supports explanations in several languages and mines past sessions to adapt to individual coding preferences over time. Sessions can be exported for review, and the system detects provider keys automatically for seamless integration. As an MIT-licensed project, it keeps all data and configurations on the user's machine with no transmission to external services beyond the chosen AI provider.
