Project Tessera

Project Tessera is an open-source, local-first memory layer for AI tools. It captures and indexes conversations and documents, builds a knowledge graph, and bridges context across multiple AI assistants like Claude, ChatGPT, Gemini, and Copilot. Tessera runs entirely on your machine, features AES-256 encryption, and ensures privacy by not requiring any cloud or API keys. It's ideal for users who work with multiple AI assistants and want persistent, encrypted, cross-tool memory and knowledge management.
