MindFrame scores three things most tools ignore: not just whether you're right, but how you reasoned, and how well you knew your own confidence.
Free plan · No credit card · All 19 modes included
Plus 5 free games, no sign-up: ASCENT, Evidence Showdown, Rule Shift, Signal Station and Memory Heist.
Choose a mode, see the estimated time, then launch straight into session setup.
Ten-second test
5 games · free, no sign-up
Each game is built around one mental skill — seeking evidence, adapting when rules change, filtering noise, remembering a route. Signed in, every finished run counts toward your progress.

From the research, not from MindFrame
Our own outcomes are not yet measured. MindFrame has not yet run a controlled study, so we do not claim it produces the effect sizes reported in the research. We will publish our own numbers, including weak ones, once we have them.

How a session works
A standard session takes about 4–5 minutes. You answer, rate your confidence before you see the result, and get three separate readings back.
— the floor every tool measures.
Explain your thinking and it is scored separately from the answer — by Claude for in-depth reasoning, by a published formula otherwise.
— the gap between how confident you felt and how often you were right.
Overconfident. Sure, and wrong more often than you expect.
Well-calibrated. Confidence matches accuracy. Learnable.
Underconfident. Right more often than you admit.

What sets MindFrame apart
Trains speed on the trained task
Improvement tends to stay on the trained task (Simons et al. 2016).
Trains emotional awareness
Adds little beyond personality in predicting performance (Joseph & Newman 2010).
Trains metacognition
Scores your reasoning and how well your confidence matches your accuracy, and shows your own trend over time.
Two ways in
A training session takes about 4–5 minutes and scores your reasoning and calibration. A game takes a few minutes and trains one skill. Both are free.
