ReasonEra is built for one purpose: pre-employment assessments. Upload a screenshot in your browser, get the answer in seconds, and learn the rule behind it. No install. No QR code. No phone pairing.
Choose ReasonEra if your practice is mostly abstract, logical or inductive reasoning and you want a tool that runs in your browser with nothing to install, no QR code, and an explanation that teaches you the rule behind each answer.
Choose TestSolve if you need one tool for many question types, including numerical, verbal and situational judgement, and you are comfortable with a desktop app and a phone for delivery.

The main differences in how each tool works, what it covers and what it costs.
| Feature | ReasonEra | TestSolve |
|---|---|---|
| Focus | Built only for pre-employment tests, strongest on abstract, logical and inductive puzzles | Numerical, verbal, inductive, situational judgement and more |

| Install required | No | Yes for the desktop app (about 15 MB) |
| QR code or phone pairing | No, answers appear on the same page | Yes, a phone is scanned in to receive answers |
| Learning support | Two modes: Quick Verify (answer only) and Tutor Explanation (step-by-step rules) | Answer, confidence score and reasoning |
| Free trial | 3 free trials with a free account | 1 free solve |
| Pricing | 49 € one-time for a 14-Day Pass with unlimited use | $14.99 for 30 questions (7 days) or $19.99 for 50 questions (14 days) |

The two accuracy figures are each tool's own, measured on different material, so they are not a like-for-like comparison. We recommend testing both on questions you care about.
General-purpose AI models are built to do everything. Reasoning-test puzzles are narrow, visual and rule-based, and they reward a model trained for exactly that. ReasonEra's published benchmark compared specialised and general models on cognitive ability tests and concluded that specialised models outperform GPT-4o, Claude and Gemini.
Read the benchmark: Specialized Models vs GPT-4o, Claude and GeminiBenchmark published by ReasonEra on Medium (2025). Results depend on the test set and method used.
The case for a tool made only for assessments.
A focused model can concentrate on rule-finding in puzzles, and we keep developing it for that purpose.
Open ReasonEra in your browser, upload a screenshot or take a photo, and read the answer on the same page. No desktop app, no phone pairing and no operating-system security prompts to click through.
Quick Verify shows only the answer so you can work out the logic yourself. Tutor Explanation breaks down the rules step by step. The goal is that you can solve the next question without help.
We maintain and develop the ReasonEra model ourselves, with the aim of keeping it among the best in this area as new puzzle types and test formats appear.
A single 49 € payment gives unlimited use for 14 days, which suits you if you are working through many abstract or inductive questions in a short period.
The ReasonEra website, pricing and test guides are available in English, Swedish, French, German, Dutch, Spanish, Danish, Italian and Polish.
Both tools cover many question types. Here is where TestSolve offers something ReasonEra does not.
TestSolve lets you capture a question with a hotkey on a computer and read the answer on a separate phone. ReasonEra runs in the browser and shows the answer on the same page.
TestSolve also sells timed practice-test packs, for example an SHL-style pack of five tests, according to its site. ReasonEra is not a library of practice tests.
TestSolve states that it shows a confidence score and combines several AI models for each answer.
For around 30 questions in a week, TestSolve's $14.99 pack can cost less than ReasonEra's 49 € pass.
Less setup. There is no installer to download and no phone to pair. You open ReasonEra, upload an image and read the result. That works the same on a laptop, tablet or phone.
No security warnings to click through. TestSolve's own install help pages explain how to get past Windows SmartScreen and macOS Gatekeeper warnings for its desktop app, because the app is new and not yet widely recognised by those systems. A browser tool never triggers those prompts.
You choose what you share. With ReasonEra you decide exactly which image to upload, so only the question you want help with is processed.
| If you… | Better fit |
|---|---|
| Practise mainly abstract, logical or inductive reasoning (Matrigma, Raven's, SHL abstract and similar) | ReasonEra |
| Want to learn the rules behind each answer, not just see the answer | ReasonEra |
| Prefer nothing to install and no phone pairing | ReasonEra |
| Want a desktop app with a hotkey and answers sent to a phone | TestSolve |
| Only need a few dozen questions and want the lowest upfront cost | TestSolve |
| Have a mixed test battery | Either, or both: ReasonEra for abstract sections and TestSolve for the rest |
Using AI to study is common and sensible. Using it where the rules forbid outside help is not, so check before any graded test.
ReasonEra is a browser-based AI tool built only for pre-employment assessments, strongest on abstract, logical and inductive puzzles.
