People who use multiple AI platforms regularly—e.g. ChatGPT, Claude, Gemini, Cursor—and are tired of re-explaining context every time they switch. It's built for anyone who uses 2+ AIs every day and wants one place their context lives.
You capture conversations with one click; Context Companion's AI summarizes them and extracts topics and categories. When you start a new chat in any supported platform, relevant context is automatically suggested or injected. You can also sync summaries to Notion and query your knowledge base from Cursor.
Context Companion works with ChatGPT, Claude, and Gemini for capturing and recalling context. It also connects to Cursor via MCP for context while coding, and syncs summaries to Notion for search and Notion AI.
