Upload a diagrammatic reasoning question, get the answer in seconds, and see which rules the diagram applies.
ReasonEra is an AI solver and tutor for diagrammatic reasoning questions. You upload a screenshot or photo of a diagram with operations or transformations; it returns the answer and, in Tutor Explanation mode, the rules the diagram applies, step by step. It is a study tool for practice.
Diagrammatic reasoning questions show input shapes passing through a set of operations, such as rotate, flip, change colour or add an element, and ask for the output or for the missing operation. Many are close to abstract reasoning but add explicit rules or symbols.
Question: An L-shape is rotated 90° clockwise and then mirrored left to right. Which result is correct?
Answer: The third shape in the figure: the L-shape after the rotation and then the mirror.
How the reasoning goes:
This question is invented for illustration and does not come from a real assessment.
ReasonEra has practice guides for these tests:

Assessment instructions differ from one employer to the next, and some tests are proctored. If anything is unclear, ask the recruiter. ReasonEra is for learning the patterns in advance.
It is a test of your ability to follow rules shown in diagrams, such as operations applied to shapes, and to work out the result or the missing rule.
Image-capable AI can attempt them, but order-of-operations and symbol rules are easy to misread. ReasonEra is built for pre-employment tests and explains the rules step by step so you can check the logic.
ReasonEra has guides and solvers for Saville Diagrammatic Analysis, Saville Swift Analysis and Hudson A-RAT 3R. See the list on this page.
Yes, there are 3 free trials with a free account. Unlimited access for 14 days costs 49 €.
ReasonEra is built only for pre-employment tests, so you upload the question and choose a mode, with no prompt to write. A general assistant is more flexible but needs a prompt, and its accuracy on visual puzzles varies.
Bring a question from your practice material and see the answer and the rule. You have three free trials to judge it.
