Permagent.ai

Permagent is a local-first AI agent desktop OS for macOS Apple Silicon. The agent, its memory, and your data live on your own hardware—privacy as a fact of the architecture, not a promise. A persistent, inspectable knowledge graph (the Brain) lets the agent learn over time, while a verified, auditable loop lets it act autonomously with machine-checkable evidence. Local models handle the always-on background work; frontier models are reached only when a task justifies the cost. Jesse Sharratt started the project with Henry and took the lead early on, captivated by the potential of powerful local AI—which is why he built both Spectral (the open-source memory engine behind the Brain) and Permagent itself as open source, to make it easy for others to benefit too.
