Context that won't
stay dead

AI is brilliant in the moment and blank the next day. Zombie Brains gives it a memory that lasts — so every session builds on the last, and nothing you've decided, built, or discussed ever gets lost.

// session 1
"We're building an email writer. Use Handlebars for templates,
never fabricate claims, pull confidence from the scoring module..."

// session 14
"I already told you this. Fourteen times."

// session 14, with zombie brains
"Pick up where we left off."
"Already loaded. You left an open question about template
caching. Want to resolve that first?"

Every AI session starts from zero. Zombie Brains makes it start from everything.

Why Zombie Brains

Three problems.
One memory layer.

Stop re-explaining your project every session

Your AI should know what you've decided, what you've rejected, and why. With Zombie Brains, it does — across every session, every conversation, every tool.

Software development

"Why did we choose Postgres over Redis?"

→ Recalls the debate from session 7, the failed Redis demo, and the rationale.

Your AI gets smarter at your project over time

Every decision, constraint, and preference accumulates. Month three's AI understands nuances that month one's AI couldn't. Context compounds like interest.

Research

"What patterns have we seen across the last 12 interviews?"

→ Synthesizes themes, contradictions, and emerging patterns from months of stored insights.

Knowledge that doesn't quit when people do

When someone leaves, their decisions and context stay in the team brain. New hires inherit months of accumulated project intelligence on day one.

Teams

"What has the backend team been working on?"

→ Surfaces decisions, constraints, and active threads from the team brain — with full attribution.

How it works

Two ways in. Same
undead memory.

🏢

For teams & enterprise

Shared brains with hierarchy, access control, and audit logging. Your team's AI shares institutional knowledge.

Knowledge survives team changes

Under the hood

Not a vector database.
A cognitive architecture.

🧠

Brain-inspired memory

Consolidation, activation decay, salience gating, spreading activation — the mechanisms of human memory, without the forgetting.

🕸

Knowledge graph

Memories auto-link via similarity. Decisions connect to constraints. Insights cluster into constellations.

🔍

Multi-pathway retrieval

Semantic search + keyword matching + graph traversal + recency + salience. Five pathways, fused with reciprocal rank.

🔒

Hard brain boundaries

Every query scoped to brain_id. No cross-brain leaks. SOC 2 compliant infrastructure. Full audit logging.

👥

Team memory

Brain hierarchy, role-based access, user attribution, cross-brain search, org policy propagation.

⚡

No LLM on our side

We embed, store, and retrieve. The AI interprets at recall time. Your data never touches an LLM we control.
