Hindsight™ is an agent memory system built to create smarter agents that learn over time. Most agent memory systems focus on recalling conversation history. Hindsight is focused on making agents that learn, not just remember.

Grok Mem is how Grok Bots remember. Sits next to Grok's own memory. Does not replace it.

Cognee is the open-source AI memory platform for agents. Give your AI agents persistent long-term memory with small models for free

Memory and context engine + app that is extremely fast, scalable, and can be run fully locally. The Memory API for the AI era.

EverOS is a Python library and local-first memory runtime for agents and makers. It gives one portable memory layer across coding assistants, apps, devices, and workflows from day one.

YC (S26) | Open Computer History | Continuously record your company computer work, map your workflows, help you find work worth automating, and power your agents' context

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

Agents work better when they remember things across sessions. With Agent Memory Repo, your agent saves what it learns from you in real time, and that memory is live across sessions. Memories link to each other, so your agent navigates them like a wiki.

Memori is agent-native memory infrastructure. A LLM-agnostic layer that turns agent execution and conversation into structured, persistent state for production systems.

Memvid is a single-file memory layer for AI agents with instant retrieval and long-term memory.

AI Agent Orchestrator with Skills System - Give AI Agents superpowers: memory search, code graph queries, agent-to-agent messaging. Manage Claude Code, Codex, Grok Build or any AI Agent from one dashboard. Move Agents between computers and locations

LongMemory is a cognitive memory engine for LLM applications and autonomous agents.

AI systems are powerful inside their current context window, but that context is temporary. Important decisions, user preferences, previous interactions, and learned knowledge disappear between sessions.

Open-source, Git-native memory for AI coding agents — deterministic local recall for Claude Code, Codex, Cursor, Gemini CLI, and compatible tools.

A Datalog engine for LLM agent memory: stratified rules, provenance-tracked facts, incremental derivation, and an MCP server that lets your harness use it as a shared brain.

The design lineage goes back to December 2025 — the first ancestor of this system (a memory-inheritance tool for an earlier AI) ran that month, and a predecessor system carried the same ideas in daily use from January 2026.
