Agent memory: long-term memory & agent memory handoff. Claude Code & Codex.

a best-effort approximation of a synthetic entity complete with all of the primatives required for long-horizon persistance. batteries included.

A free, open-source desktop app for getting work done with AI. It shows you what it would remember before it saves anything.

RushDB is a self-describing, graph-native database that helps AI agents reason over data with confidence: progressively introspect what's queryable—without guesswork.

Make AI agents and AI workflows measurably reliable. Epistemic measurement, Noetic RAG, Sentinel gating, and grounded calibration for Claude Code and beyond

Open-source memory and context for user-aware agents: scoped memory, provenance, retrieval quality, correction, boundaries, evals, and MCP/HTTP access.

An open-source, vector-free long-term memory engine for AI agents, achieving SOTA on LoCoMo and LongMemEval with significantly less context.

LeanKG: Stop Burning Tokens. Start Coding Lean.

Server-enforced workflow discipline for AI agents. An MCP server providing persistent work items, dependency graphs, quality gates, and actor attribution. Schemas define what agents must produce — the server blocks the call if they don't. Works with any MCP-compatible client.

Open-source cognitive coprocessor with active memory for AI agents — persistent recall, semantic search, overnight dreaming, verified facts, encrypted USB sync. MCP server; works with Claude, ChatGPT, and any local LLM. Built by one maker and his agents.

Your private, on-device personal AI assistant for macOS and Windows. Chat, create, search files, and connect tools with local models. Includes an OpenAI-compatible API. Opt-in Pro sees, remembers, reflects, and acts with your approval. No cloud or account.
