Overview
Context.dev is a web context API designed for AI products and agents. It provides a unified platform for scraping any URL, crawling websites, converting pages to LLM-ready markdown, extracting structured data, and retrieving brand intelligence like logos, colors, and company information. It is YC-backed and emphasizes quick integration for developers.
Chert is an AI video agent platform for FaceTime, often described as 'Vapi for FaceTime.' It allows developers to build and deploy interactive AI agents that can answer and place FaceTime calls. The key differentiator is the use of the caller's camera to provide visual context, enabling agents to understand what the user is showing.
