Anki with Uncertainty

Turn any flashcard deck into a calibration training tool

An Anki card that lets you input a range

Instead of the exact answer, enter your 90% confidence interval - an interval that you're 90% confident the answer lies within.

The back of the card shows your score

Earn more points for a narrower correct interval, lose more points for a narrower incorrect interval.

Based on your score, we recommend you press Hard, Good or Easy.

Higher scores = longer before you need to review the card again!

See your Anki calibration scores

Track your calibration: press Tools → Show calibration scores. Perfect calibration = your X% confidence interval is correct X% of the time.
