Upload a logical or deductive reasoning question, get the answer in seconds, and see the reasoning step by step.
ReasonEra is an AI solver and tutor for logical and deductive reasoning questions. You upload a screenshot or photo; it returns the answer and, in Tutor Explanation mode, the chain of reasoning that leads to it. It is built to help you learn, not to replace your own reasoning.
Deductive questions give you statements or rules and ask what must follow. Some are text-based, such as syllogisms and conditionals. Others are visual or interactive, such as scheduling and ranking tasks. The key is to use only what is stated.
Question: All sales reps have a company laptop. No one with a company laptop can install their own software. Which conclusion must be true: (A) Sales reps cannot install their own software, (B) Some sales reps can install their own software, (C) People without laptops are sales reps, (D) Nobody can install software?
Answer: (A) Sales reps cannot install their own software.
How the reasoning goes:
We wrote this example ourselves; it is not a live test question.
ReasonEra has practice guides for these tests:
See all supported tests on the ReasonEra homepage.
| Category in the benchmark | General models tested | Specialised models |
|---|---|---|
| Deductive and verification logic (SHL, Talent Q style) | 54–77% | 94–97% |
ReasonEra measured these itself in a benchmark published on 30 November 2025, using 500+ analogous public items from 15 providers and no proprietary questions. Testing was blind and inputs were identical. The general models were GPT-4o, Claude Opus 4.5, Gemini 2.0 Pro, GPT-o1 and Grok 2; newer versions exist now. Independent verification has not been carried out. Read the benchmark.
We built ReasonEra to help people learn how reasoning questions work. Whether outside tools are allowed in a live test is the employer's decision, so check the terms of the one you are sitting.
It is a tool that reads a logical or deductive reasoning question from an image and gives the answer. ReasonEra also shows the reasoning so you can follow each step.
Yes. General models can hallucinate steps under pressure, which is why ReasonEra shows its reasoning for you to check. ReasonEra's published benchmark reported higher accuracy for specialised models than for the general models it tested.
ReasonEra has guides and solvers for tests including SHL logical reasoning, Sova logical reasoning, Korn Ferry Elements and Aspects logical, and Aon GapChallenge. See the list on this page.
ReasonEra handles standard and interactive deductive formats for the tests it supports, such as scheduling and ranking tasks. Results can vary with image quality.
Every account starts with 3 free trials of the solver. If you want more, the 14-Day Pass is 49 € for unlimited use across the supported tests.
A quick way to judge any tool is to use it on questions you already know. Start free, and move to the 14-Day Pass only if it earns it.
