Your AI agent
remembers everything.
Give your agents persistent, versioned memory that builds with every session. Knowledge compounds — your stack, decisions, and context are always there, always current, across every tool and every agent.

Watch it work.
Real agent calls. Real memory. See how Memstate keeps your agents in sync — across sessions, tools, and entire swarms.
Agent starts fresh — Memstate already knows your stack.

Built differently. Proven in public.
Memstate uses a facts-first memory architecture built for agents that need to remember what’s true, not just what’s similar. The open-source benchmark shows that difference in measurable results.
Why Memstate wins
Facts-aware memory improves accuracy and keeps context consistent as requirements change.
All scenarios, scoring, and fairness notes are public in the leaderboard and methodology docs.
Every agent. One memory.
Built-in memory in Cursor, Claude Code, Cline, and Windsurf is siloed to that tool. Memstate is a single, project-scoped memory bank that every agent in your stack reads and writes — even when a whole swarm is running in parallel.
GitHub Copilot
Kilo CodeWorks across every session and every tool
Start a task in Cursor, continue it in Claude Code, finish it with Cline. Your project context — architecture decisions, API keys, stack choices — is always there, always current.
Built for agent swarms
Running a planner + coder + reviewer in parallel? All agents read the same memory, write back to the same keypath, and Memstate handles version conflicts automatically. No duplicated context, no contradictions.
Faster tasks, lower token costs
Agents that already know your stack skip the discovery phase entirely. Swarms that share memory don't re-fetch the same facts. Fewer tokens in, faster answers out.
Unlike built-in agent memory
Set up in 30 seconds. Seriously.
No infrastructure. No database to manage. One command and you're done.

Connect
Run the one-line installer. It auto-detects your agent and configures the MCP in seconds.
Works with every MCP-enabled agent
Remember
Your agent stores facts naturally. Our purpose-built AI models extract and structure them in milliseconds.
Fastest extraction in the market
Recall
Agent asks a question, gets the current answer. Old versions are tracked, not dumped into context.
Always current, never stale
Memory That Gets Smarter
Memstate learns through every interaction — tracking what's new, versioning what changed, and building domain-focused knowledge banks that make your agents more effective over time.
Knowledge That Compounds
Every new memory builds on the last. Your agents start each session with richer context than the one before — not a blank slate. The more you use Memstate, the smarter your agents become.
Versioned Memory — Never Stale
Every update creates a new version. Agents always get the current answer, not a pile of contradicting old context. Roll back any decision without losing history. Memstate knows what changed, when, and why.
Full History, Zero Amnesia
Old facts are never deleted — they're versioned. Agents can trace how a decision evolved over time. You get the benefit of forgetting stale context while keeping the full audit trail intact.
Projects Make Agents Smarter
Organize memory into focused projects and build targeted knowledge banks for specific agents or swarms. A research agent, a coder agent, and a market agent each get exactly the context they need — nothing more, nothing less.
Why Developers Choose Memstate
Built for production agents that need reliable, organized, version-controlled memory.
Vector search returns similar text, not the right answer. Old discussions and contradicting opinions all look equally relevant. Memstate gives you the current fact.

Give your agents memory that compounds.
Memstate captures context, decisions, and facts in one place — so every session builds on the last.
