Preflop Explorer is an interactive poker range viewer and study tool. Follow a legal action line, compare consecutive player ranges, and inspect exact raise, call, and fold frequencies for all 169 starting-hand classes.
A static chart shows one snapshot. Preflop Explorer keeps the action context, the previous range, and the current decision together.

Follow legal action lines
Start at the root and choose each available raise, call, or fold to reach the exact spot you want to study.
02 / compare
Compare ranges side by side
Keep the previous player's strategy beside the current decision at the same grid size.
03 / inspect
Read the exact mixed strategy
Open any of the 169 hand classes to inspect its raise, call, and fold frequencies instead of a single simplified action.

06 / questions
Preflop Explorer questions, answered.
Is Preflop Explorer a poker range chart?
It is interactive rather than static. You can follow a legal 6-max action line, compare consecutive ranges, and inspect mixed frequencies for all 169 starting-hand classes.
Can I use it as a preflop trainer?
You can use the hosted product for range study and decision review. Developers can use Pokerai API to add quizzes, grading, spaced repetition, and other custom training modes.
Does the public browser expose a Pokerai API key?
No. The hosted explorer uses the signed-in user's same-origin session and a controlled application endpoint. Custom products should keep Pokerai API credentials in a trusted backend.
What can I build with Pokerai API beyond this explorer?
You can build custom range viewers, poker trainers, hand-review systems, coaching dashboards, and analysis workflows using the documented preflop, postflop, and solver API families.
Scope and provenance
Preflop Explorer is a first-party Pokerai interface built on the existing Preflop library. It is designed for presolved strategy study by authenticated users. It does not enable real-time assistance at real-money tables.
