You don't remember how you breathe.
You won't remember how agents know what they know.
That is Self.
Self · Geometrical · 2026
What Self is
Self is the episodic memory substrate on which every agent you interact with operates — capturing intention, decisions, patterns, and criteria across all your roles simultaneously.
Self operates beneath every agent, every OS integration and every model. It does not compete with agents. It governs what they know.
Agents read from Self. They never write to it without a staged commit, a validation pass, and explicit permission. The user is always in control of what the agent knows.
Beneath every agent
Operates beneath agents and OS integrations. Controls what every agent knows before it speaks. Agents read. They never write without a staged commit, validation pass, and explicit permission. The boundary between what an agent knows and what it may know.
Local-first
Not a policy. An architectural constraint. Nothing leaves the device without explicit, user-defined permission. Not a feature — an architectural commitment.
Multi-role
Infers founder, parent, learner, partner simultaneously from behavioral signals. No declaration required. Context switches automatically as the active role shifts.
Zero new interface
Configure once. After that, Self works inside the apps you already use — a question when something is unclear, a weekly summary you can correct. No new app. No memory screen. No prompt engineering.
No fine-tuning
Does not touch model weights. Runs on any LLM, local or remote — Claude, GPT, Gemini, Llama, any open model. Substrate-level, model-agnostic.
Format · .aix
A 9-dimensional identity snapshot. Machine-readable, portable, spatiotemporally traceable. The PDF of the agent era. Open format — Apache 2.0.
Privacy · Patent P202631047
PII transformed before any model interaction. No equivalence tables transmitted. Two original inventions — Session Privacy Protocol and PII Tokenization Without Fine-Tuning. Filed OEPM July 2026.
Hardware · Runs where inference runs
Runs today on macOS — down to a 2015 laptop with no GPU. Device-agnostic by design, so it can follow the new generation of AI-native hardware as it arrives.
Recovery · Roadmap
Designed to live in your personal ecosystem. Encrypted P2P sync across your devices. Recovery phrase for key reconstruction. No cloud intermediary. No single point of failure.
Every agent you use,
finally knows you.
Only you decide how much.
