KARTILYA.PH

§ About

The law, made usable.

KARTILYA.PH is a free, AI-native archive of the law of the Philippines — the 1987 Constitution, the Codes, and the Republic Acts. The name borrows from the Kartilya ng Katipunan, the 1896 primer that taught ordinary Filipinos their rights and duties: a kartilyais a primer, and this is the people’s primer to the law.

§ What this is

Public law should be usable, not just availableThe law of the Philippines is already free to read. But scattered across legacy sites, it is hard to search, harder to ask, and impossible to trust to a machine. Availability is not access. This rebuilds the law as one corpus you can question in plain language.
A generation behind, by defaultThe institutions that freed the law — LawPhil, the Official Gazette, the E-Library — did the hard, essential work. The interfaces simply never modernized. We stand on that foundation and add the layer it was always missing: structure, meaning-based search, and verification.
Verifiable authority, not a black boxLegal answers are worthless if you cannot check them. Every answer here is cited to the exact provision and checked against the source text by a verification firewall. Anything the source does not support is flagged. The machine is never trusted on its word.
Built in the open, for everyoneLawyers, students, public servants, and citizens read the same law. A free public layer serves all of them — and gives the institutions that steward Philippine law a modern front door to the work they already do.

§ Who built this

KARTILYA.PH is built by Karlo Dizon, a lawyer and technologist from Bataan. He earned a B.A. with distinction in political science from Yale, an M.Sc. with distinction in comparative politics from the London School of Economics, and a J.D. from Stanford Law School. Along the way he held internships at the White House and in the United Kingdom Parliament. He began his career in appellate, constitutional, and regulatory litigation at WilmerHale, one of Washington, D.C.’s leading law firms, and serves on the New York State Bar Association’s Committee on Artificial Intelligence and Emerging Technologies. He has also led editorial and content strategy for some of the world’s largest investment conferences, working with heads of state and the leaders of major financial institutions and sovereign wealth funds.

KARTILYA.PH is a deployment of Refoundation, the same engine behind Territorial Review, a free, AI-searchable archive of the law of the U.S. territories. Both are built on a single idea: public law should be not just available, but usable.
