Inside the grader
Watch accuracy climb and EV loss shrink.
Toggle day / week / month / year. Bars show correctness, the line tracks EV loss, and callouts flag your best and worst periods and whether you're trending up or down.
Every mistake priced. Ranked by total EV bled.
Auto-grouped by mistake type + spot — loose-calls, spew-jams, min-raises where a jam is +EV — with the exact hands, stack depths, and actions that cost you the most.
Slice decisions by position, spot, depth, or hand.
Every graded hand ordered worst-leak first. Filter by UTG–BB, spot type, 5 stack-depth buckets, correctness, or hand class. Skipped hands logged separately so nothing is silent.
Step through every preflop action at the table.
See stacks, effective bb, pot, your hand, your line, and the solver's line side by side — with the correct range highlighted on a 13×13 grid and your hand marked in red or green.
A trend line that doesn't lie.
