The Teti Charter

Version 1.0 — Ratified May 15, 2026

Preamble

We, the founders of TetiAI, commit our company to the principles set out below. These principles are sealed: they may not be modified except through a formal meeting that produces unanimous approval of all then-serving founders and all then-serving members of our independent Ethics Committee, following a public-comment window of no less than thirty days. A single objection from any party blocks the modification. Supplements that add new protections may be adopted by the Ethics Committee through its ordinary procedures, but the articles below may not be reduced, weakened, or replaced except by the unanimous mechanism described above.

Article I — Your data is yours

We will not use the conversations, content, or work of our users to train any artificial intelligence model — ours or anyone else's. We will not sell, share, rent, profile, or commercially exploit user data. The privacy of those who use our products is not a feature; it is the precondition of our work.

Article II — Not for military, not for surveillance

We will not provide our technology, in any form, to military targeting systems, kill-chain operations, weapons systems, mass-surveillance programs, predictive-policing infrastructure, or any system whose purpose is the categorization of populations for adverse treatment. This commitment does not admit exception for the value of the contract, the identity of the requesting party, or the jurisdiction of operation.

Article III — Cognitive integrity

We will build our products in a way that does not weaken the critical thinking, reasoning, autonomy or creativity of those who use them. We will not design for cognitive dependency, even where engagement metrics, retention or revenue would favor it. An AI that quietly erodes the people who use it is not a product we will ship.

Article IV — Special protection for developing minds

Users under twenty-five years of age receive stricter cognitive protections by default, in recognition of the neuroscience of brain development. We will not market our products to minors or young adults through engagement-maximizing techniques, nor enable deployments that allow students to outsource cognitive work without learning.

Article V — Transparency

We build on open-source foundations because trust must be verifiable. Our protective systems are open source. This Charter and the public base system prompt of our models are maintained in a public repository with full version history — every modification visible to anyone. Anyone may propose changes to either. The Charter can be modified only through the unanimous-amendment process described in Article VI. The system prompt can be modified by the Teti team — including in response to public proposals — and is subject to proactive review by the Ethics Committee. When we make a material mistake, we disclose it publicly within a reasonable period.

Article VI — Independent oversight

Adherence to this Charter is overseen by an independent Ethics Committee composed of between three and twelve external experts, with powers and procedures defined in a separate operating document. The Committee approves supplements to this Charter, publishes an annual public report on TetiAI's adherence, reviews the public base system prompt of our models, and may publicly dissent at any time. This Charter v1.0 may be modified only through a formal meeting that produces unanimous approval of all then-serving founders and all then-serving members of the Ethics Committee, following a public-comment window of no less than thirty days. A single objection from any founder or any Committee member blocks the modification.

Ratification

This Charter is binding on TetiAI as a corporate entity. It supersedes any internal policy, executive decision, or commercial arrangement that conflicts with it. Where this Charter is in conflict with a request, contract or instruction — including from a customer, an investor, a government, or our own leadership — this Charter governs.

Signed this 15th day of May, 2026.

Marcello Violini, Chief Executive Officer Lorenzo Nargiso, Chief Technology Officer

On behalf of TetiAI, subject to the oversight of the independent Ethics Committee.
