Subgame brings your hand history, fast native solvers, and an AI agent into one study app. Ask a question in plain language. It queries your hands, runs the solves, and builds the charts to answer it, with every assumption stated so you make the call.

Studying usually means exporting from a tracker, rebuilding the spot in a solver, and comparing by hand. Subgame has all of it in one app, and the agent can operate every part of it. Everything works without the agent, too.
Step through any hand street by street, with stacks, bets, and the pot at every action. Open it from the hand table, from a chart, or from the chat.
Net won, all-in adjusted, showdown and non-showdown winnings over every hand, split by currency, with excluded hands counted and reported.
New hands arrive while you study. Imports read your tracker and hand-history folders and never write to them.
Filter every imported hand by game, stakes, position, cards, or board, and see your stats for that slice.

See the range you actually played from any position, built from your own hands, next to the chart you study from.
A fast native solver runs on your machine. Set up a spot, or let the agent build it from your hands, then explore strategies and EVs action by action.
Start from a question, a hand, or a spot you keep getting wrong.
The agent finds the matching hands and computes your actual frequencies and results.
It builds the spot in the solver from your own hands, then compares your play to the solution.
Results open as views. Change an assumption and re-solve without starting over.
Subgame never presents a guess as a fact. Every answer separates what your hands show from what it assumed, so you know how far to trust it.
What you did is a measurement. How your opponents would respond is an assumption. Subgame labels each one.
Subgame is for reviewing hands and studying spots after you play. It does not run alongside live games.
Connect the AI provider and model you prefer with your own API key. A managed subscription will be available for players who would rather not set that up.
Your hand database lives on your machine. Imports are read-only and never change your tracker's data.
In game theory, a subgame is one part of the game tree that can be solved on its own. Modern solvers work this way: they solve the spot in front of them, in depth, on demand. Subgame is built for studying the same way, one spot at a time, starting with the spots that matter most in your own hands.
