5.3x more accurate than Mem0

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.

Open-Source Benchmark

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.

Conflict Detection95.0% vs 20.2%
Cross-Session Continuity88.7% vs 17.2%

ONE SHARED MEMORY BANK

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.

Works 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.

1

Connect

Run the one-line installer. It auto-detects your agent and configures the MCP in seconds.

Works with every MCP-enabled agent

2

Remember

Your agent stores facts naturally. Our purpose-built AI models extract and structure them in milliseconds.

Fastest extraction in the market

3

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.
