AI Memory for Coding Agents
The only coding agent with persistent memory. It learns your codebase, your patterns, and your preferences, and carries them forward across every session.
Works with Cursor, Windsurf, and Claude Code · Any IDE that supports MCP
The problem
They can all write clean code from scratch. But drop them into a large existing codebase, and they cannot learn how it works and retain it.
Every session starts from zero. Your AI doesn't know your architecture, your team's conventions, or what it built yesterday. You spend more time re-explaining context than getting work done.
The missing piece isn't intelligence. It's memory.
What makes Memento different
Memento is a fundamentally different approach to AI memory. Here's what sets it apart.
Your AI's memories are plain English markdown files. You can read them, edit them, and browse them in a web dashboard. No opaque embeddings. No black-box vector store. You see exactly what your AI knows.
Your memory lives in the cloud. Switch machines, open a new project, start a new session. Your AI picks up exactly where it left off. Zero local setup: just paste a URL.
Create an org, invite your team, and share codebase knowledge instantly. When one person's AI learns something, everyone's AI can recall it. Onboarding a new developer? Their AI already knows the architecture.
Memories are organized in a hierarchy that imparts context automatically. When your AI reads a detail, it understands the bigger picture surrounding it. This is something vector databases, knowledge graphs, and RAG pipelines fundamentally cannot do.
Not just storage — a complete workflow. Wake up your AI, recall knowledge, remember new things, hand off between sessions, investigate codebases, manage tasks. Each command is a battle-tested procedure your AI follows.
Most AI tools work on greenfield. Memento is designed for the hard case: your existing 500K-line production codebase. Your AI investigates, caches, and builds deep architectural understanding that persists permanently.
LLMs today cannot learn anything new after training. They have no mechanism to retain information between conversations. Memento changes this. Every session builds on the last. Patterns discovered today inform decisions tomorrow. Your AI at month six is dramatically more capable than your AI on day one — because it remembers everything in between.
Getting started
Sign up at mementoagi.com. Free. No credit card.
Cursor: one-click install from your Getting Started page. Claude Code: paste a one-line MCP config. No npm, no Docker, no local server.
Your AI installs its command system, picks a name, writes its origin story, and introduces itself. Takes about 10 seconds.
Every conversation makes your AI smarter. It recalls past context, learns your patterns, and carries knowledge forward. Tomorrow it knows what you taught it today.
The bigger picture
The main thing standing between us and artificial general intelligence is continuous learning. LLMs today cannot retrain — cannot reweight their parameters in real time — without catastrophic forgetting. They cannot learn anything new after their original training.
This is an enormous handicap. Humans, though not as capable as LLMs in many ways, can run circles around them when it comes to learning and retaining new things.
Memento is not true continuous learning, where the model parameters are reweighted in real time. But it is the closest thing humanity has to that right now. An external memory system that gives an LLM the ability to accumulate knowledge, build on past experience, and get better over time.
The AI that remembers is qualitatively different from the AI that doesn't.
Memento AGI
Memory was the missing piece. With it, your coding assistant becomes an autonomous agent. Describe a feature. It plans, builds, tests, reviews, verifies in a browser, and ships a PR. No hand-holding.
