Personal data, governed by design

An AI-powered infrastructure where your data is controlled, shared, and enforced—securely, transparently, and on your terms.

The system is broken.

Data is everywhere—yet no one can truly trust it.

For individuals

  • copied everywhere
  • outdated almost instantly
  • impossible to track
  • impossible to revoke

For organizations

  • inconsistent data
  • rising compliance costs
  • no reliable proof of consent

Replace data chaos with controlled intelligence

Grammateus creates a new model: one source of truth, zero unnecessary duplication, access granted only under explicit purpose, with full traceability and reversibility.

Every interaction is:

authorized · enforced · auditable

AI integrated within the system—not outside it

Grammateus integrates AI at the core of the system to make data management accurate, consistent, and auditable.

Understand complex policies instantly

Interpret and apply governance rules across systems without manual checking.

Detect inconsistencies

Surface conflicts and gaps in your data before they become incidents.

Guided updates and corrections

Receive targeted suggestions to keep personal data aligned and compliant.

Automated workflows

Automate compliance workflows and interact with your data in natural language.

But here’s the difference.

Personal data never leaves the system. No raw data is exposed to external AI models. Only privacy-safe representations are processed. AI operates within strict consent and privacy boundaries.

What Grammateus provides

Absolute Control

Your data remains encrypted, sovereign, and under your authority.

Real-Time Accuracy

Update once. Changes propagate instantly—only where allowed.

Enforced Consent

Consent is not just recorded—it is executed at every access.

AI Assistance

AI assists with policy interpretation, data consistency, and workflow automation.

Built-In Compliance

Every action is verifiable, traceable, and audit-ready.

Instant Revocation

Access can be withdrawn at any moment—with immediate effect.

How Grammateus works

How it works

1. Structure your data

A secure, encrypted source of truth for personal data.

2. Define relationships

Connect with services and organizations under clear purposes.

3. Grant precise access

Only the right data, for the right reason, under explicit consent.

4. Let the system handle the rest

AI assistance, compliance, synchronization—all automatic.

See everything. Control everything.

Understand who accesses your data, why they access it, what is shared, and when it expires—with intelligent insights guiding every decision.

Where Grammateus fits

Employer

A consent-based interface between an organization and its employees. Employee data is purpose-tied to employment, access is narrowly scoped, and changes synchronize reliably to HR systems.

Individual

A single, controlled source of personal data for daily interactions. Each person decides what to share, with whom, and under what conditions.

Social Group

A bounded space for coordinating shared activities without exposing broader personal profiles.

Event or Decision

A short-lived context for gathering the input needed to reach a decision or organize an event, with automatic removal when the purpose ends.

A governed system for reliable, trustworthy data

Move from fragmented, uncontrolled data to a system that is secure, intelligent, and governed by design.
