ContextStream wires your AI assistant into a persistent memory and knowledge layer across your codebase, conversations, and team tools. It exposes semantic search over code, a lessons system that captures failures and decisions, session memory that survives context window pressure, and direct integrations with GitHub, Slack, and Notion. The server indexes your project locally and syncs with a hosted service, then surfaces relevant context automatically through a SmartRouter that analyzes each message. You get dependency graph queries, multi-modal media indexing, and hybrid search without manually feeding files into prompts. Setup drops an MCP config into Claude Desktop, Cursor, VS Code with Copilot, or OpenCode, and the tools hook in transparently from there.
