About Kinstl

Kinstl is an AI day-planner that computes days that actually hold. A constraint solver sequences commitments, a multi-modal routing engine supplies real travel times from live New York and Paris transit feeds, and an assistant edits the plan conversationally — without ever inventing planner output. Kinstl is live today as a web beta.

What we build

Most planners record intent; Kinstl checks it against reality. Every plan is compiled into a constraint model and solved with CP-SAT, every movement leg is computed against the MOTIS routing engine — no estimated travel times — and every result ships with an inspectable record of why the day is feasible.

The product runs in the browser today: a planning dashboard with a sequenced timeline, live route maps, and an assistant wired to the same planning tools. You can see the real interface on the product tour without creating an account.

Founder

Luidgi Bergerin

Founder & Engineer

Luidgi designs and builds Kinstl end-to-end — the CP-SAT planning engine, the MOTIS routing integration with live New York and Paris transit feeds, the assistant runtime, and the web product itself. Kinstl is independent and bootstrapped: every part of the system, from solver to interface, is built and operated by its founder.

See it live

The fastest way to understand Kinstl is to look at the live planning surface. Beta accounts are approval-based while city coverage is verified — but the product tour is open to everyone.
