PulseAI: Browser-Based Coding Assistant Tool (TreeHacks 2025 Codeium Prize Winner for Best Use of Windsurf)

PulseAI is a tool that enhances your AI coding assistant experience by providing your assistant with information about your (voluntarily captured) browser activity. By providing your assistant with a better understanding of your work, you'll be able to work with an agent that provides targeted suggestions and aid.

Features

• Screenshot Capture: A Chrome extension captures your browser screen and sends it to your PulseAI backend for processing.
• Autonomous Search: Perplexity and Mistral are used to browse the web for related topics, fetching real-time information that may be relevant.
• Vector Search: All of the retrieved search information is stored using ChromaDB, enabling semantic searches that retrieve relevant content quickly.
• MCP Integration: Seamless integration with Codeium's Windsurf/Cascade MCP framework.
