Lattice Notes

Lattice is a local-first workspace designed for people who think across documents, structured data, code, and AI. Instead of separating notes, databases, whiteboards, files, and automations into different applications, Lattice brings them together in a single open platform built around standard file formats and a fast native desktop experience. Your data remains yours, stored locally and organized in a way that’s human-readable, portable, and accessible to both people and AI. Beyond note-taking, Lattice serves as a foundation for intelligent workflows. Built-in AI can understand and organize your workspace, search across structured and unstructured data, generate content, automate repetitive tasks, and connect to external tools through an extensible plugin and MCP ecosystem. Optional cloud services add encrypted backup, sharing, publishing, and scheduled automations without sacrificing the local-first architecture, giving you the speed and privacy of a desktop application with the convenience of modern cloud collaboration. We use Pioneer to provide an affordable integrated AI agent which can do embedded and hybrid search over the workspace's embeddings via a local Actian AI DB instance.
