The Portable Brain for AI Agents
More Than Memory. It's Cognitive Infrastructure.
- Zero Context LossEvery session builds on every session before it. Decisions, preferences, and reasoning travel across tools and teams.
- Your Brain. Your Tools. Everywhere.Create a personal SubCortex brain keyed to your identity. Plug it into various products and services. Your preferences, expertise, and working style follow you wherever you go.
- Rapport That CompoundsYour agent reads the room. Frustration, excitement, trust — tracked as living signals that decay naturally over time.
- Ship Personality Without DeploysConfigure voice, goals, and domain expertise from a console. Ship behavior changes instantly. No code. No release cycle.
- A Living Knowledge GraphPeople, teams, projects, and decisions form a relational mesh your agent reasons over — not just retrieves from.
- Cognitive Intake, Not Dumb StorageEvery incoming fact is validated, deduplicated, and checked for contradictions before it enters memory. Noise stays out.
Bi-Temporal Memory
Your agent knows when something was true — and when it learned about it.
Every assertion in SubCortex carries two timelines. Business time tracks when a fact was valid in the real world. Transaction time tracks when the system recorded it. This means your agent can answer questions other systems can't: "What did we believe on March 3rd?" "When did we first learn this changed?" "Show me the state of the world as we understood it last Tuesday." This isn't a feature — it's a foundational design principle that makes every other capability more powerful.
Full Provenance Chain
Every fact knows exactly where it came from.
Who said it? Was it a human, an AI agent, a system import, or derived from other assertions? SubCortex tracks the full lineage of every piece of knowledge — source, method, timestamp, and confidence. When your agent makes a recommendation, you can trace the reasoning back to its origin. When two facts contradict, the provenance chain tells you which one to trust. In a world where AI-generated knowledge is growing exponentially, knowing the origin of what you know isn't optional — it's everything.
Confidence-Scored Knowledge
Not everything your agent knows is equally certain.
Every assertion carries a confidence score from 0 to 1. A fact confirmed by a human is different from one inferred by an AI model. A fresh observation is different from a months-old assumption. SubCortex makes this explicit — so your agent can weigh what it knows, surface what it's uncertain about, and never present a guess with the same authority as a verified fact. Confidence isn't a metadata field. It's the difference between an agent you trust and one you don't.
Immutable Knowledge, Living History
Nothing is deleted. Everything evolves.
When your agent learns something new that contradicts what it knew before, SubCortex doesn't overwrite. It supersedes — creating a new assertion and linking it to the one it replaced. The old knowledge is still there, still queryable, still part of the timeline. This means you get a complete epistemic history: what was believed, when it changed, and why. Auditors can trace decisions. Teams can understand how their understanding evolved. And your agent never loses context — even context it's moved past.
Portable Agentic Brain
A brain that belongs to you, not to any platform.
Today, every AI tool you use is a silo. Switch tools, lose context. Start a new session, start from scratch. SubCortex breaks that pattern. Create a personal brain keyed to your identity. Connect it to your IDE, your coding agent, your workflow tools. Your expertise, preferences, and decisions follow you everywhere — accumulating value across every interaction, in every tool. The more you use it, the smarter it gets. And you own it. Not your employer. Not the platform. You.
