ART/GTO — the poker GTO solver you actually own.

ART/GTO is a desktop poker GTO solver for No-Limit Hold'em. It runs Discounted CFR (DCFR) on your own CPU, writes the entire solved game tree to a compact open, self-contained file you keep forever, and ships with a free, browser-based game tree viewer for studying postflop poker strategy locally.

Build your own, independent GTO strategy

Most poker solvers lock your solutions inside a proprietary cloud or binary you only rent. ART/GTO is the opposite: it runs entirely on your machine, with no subscription, no metering, and no account your work depends on. Every solution is a single, self-contained file holding the complete solved tree — ranges, bet sizes, strategies, and expected values for every node. Read more in Build your own GTO solutions.

A solver with an open export format

Solutions are saved in an open, documented export format (the single-file .artgto binary). Your solved trees are portable, durable, and yours — readable for as long as you keep the file, with no vendor lock-in. See the file formats reference and the web viewer.
