Personal data, secured by design, controlled by you.
An AI-powered infrastructure that lets you control and share your data—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- outdated almost instantly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 introduces a new model: a single source of truth, no unnecessary duplication, and access granted only for clearly defined purposes, with full traceability and reversibility.
authorized · traceable · auditable
AI embedded at the core of the system
Grammateus embeds AI directly into the system to make data management more accurate, consistent, and verifiable.
Interpret and apply governance rules across systems without manual checking.
Identify conflicts and gaps in your data before they turn into incidents.
Receive targeted suggestions to keep personal data aligned and compliant.
Automate compliance workflows and interact with your data in natural language.
Personal data never leaves the system. No raw data is exposed to external AI models. Only data processed in a privacy-preserving way is used. AI operates within strict consent and privacy boundaries.
What Grammateus provides
Your data remains encrypted, sovereign, and under your authority.
Update once. Changes propagate instantly—only where allowed.
Consent is not just recorded—it is executed at every access.
AI assists with policy interpretation, data consistency, and workflow automation.
Every action is verifiable, traceable, and audit-ready.
Access can be withdrawn at any moment—with immediate effect.
How it works
A secure, encrypted source of truth for personal data.
Connect with services and organizations under clear purposes.
Only the right data, for the right reason, under explicit consent.
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
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.
A single, controlled source of personal data for daily interactions. Each person decides what to share, with whom, and under what conditions.
A bounded space for coordinating shared activities without exposing broader personal profiles.
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.
