Both TestSolve and ReasonEra are AI-powered aptitude test solvers — you upload or capture a test question and the AI returns the answer. But they take fundamentally different approaches to the problem: ReasonEra focuses on abstract and inductive reasoning with manual screenshot uploads, while TestSolve covers all question types with automatic screen capture and stealth answer delivery to your phone.
This page breaks down exactly where each tool is strong, where it falls short, and which one fits your specific situation.

If you only need to pass one test with 20–30 questions, TestSolve is ~70% cheaper ($14.99 vs €49). If you plan to use the tool daily for two weeks across multiple tests, ReasonEra's unlimited pass may be better value — but only if those tests are abstract/inductive (since that's all ReasonEra covers).
Abstract and inductive reasoning specialisation: ReasonEra was built specifically for pattern-recognition tests — Matrigma, CCAT spatial, Cognify grid puzzles, Mercer Mettl MTAR. For these specific test types, their AI is finely tuned and claims 98% accuracy on Matrigma matrices. If your test is purely abstract reasoning, ReasonEra's specialised focus is a genuine advantage.
Speed on pattern questions: Because ReasonEra's solver is optimised for a narrow set of question formats (matrix patterns, sequence completion, odd-one-out), it can return answers near-instantly. For simple 3x3 matrices, the response time approaches zero.
No install required: ReasonEra is entirely browser-based — upload a screenshot, get an answer. No desktop app to install, no QR code to scan, no phone needed. For candidates on locked-down machines where installing software is impossible, this is a practical advantage.
Unlimited for 14 days: At €49, you can solve as many questions as you want within the 14-day window. If you're facing multiple abstract-reasoning tests across different employers in the same fortnight, the unlimited model saves money versus per-question pricing.
Stealth — answers on your phone, not your screen: This is the fundamental difference. ReasonEra shows the answer on the same screen where you're taking the test. If your test is monitored (screen recording, tab-switch detection, proctoring software), the ReasonEra browser tab is visible. TestSolve sends answers to your phone via QR-linked WebSocket — nothing ever appears on your test screen. The process is invisible at the OS level (no tab switch, no clipboard access, no browser focus change).
Automatic capture: With TestSolve, you press F8 and the AI captures your entire screen automatically. With ReasonEra, you manually take a screenshot, switch to their browser tab, upload the image, wait for the result, then switch back to your test. That's 3–4 tab switches per question — each one detectable by the test platform.
Full test coverage: ReasonEra covers abstract/inductive reasoning only. TestSolve covers numerical reasoning, verbal reasoning (True/False/Cannot Say), data interpretation, situational judgement, and abstract/inductive — every section of an SHL, Kenexa, or HireVue assessment. If your test has a numerical section followed by a verbal section, ReasonEra cannot help with either.
Multi-model consensus: TestSolve runs multiple AI models in parallel and shows you the consensus vote + confidence score. This means higher accuracy on ambiguous questions — if two models agree and one disagrees, you know the answer is likely correct. ReasonEra uses a single model with no consensus mechanism.
70% cheaper for a single test: At $14.99 for 30 questions, TestSolve costs roughly a third of ReasonEra's €49. Most candidates only need to pass one test for one employer — they don't need 14 days of unlimited access to abstract reasoning only.
ReasonEra is a strong tool if your test is purely abstract/inductive reasoning (Matrigma, CCAT spatial, Cognify) and you're not worried about detection. Their specialisation in pattern-matching AI is genuine, and the unlimited model suits candidates facing multiple abstract-reasoning tests.
TestSolve is the better choice for most aptitude test scenarios: mixed-format tests (numerical + verbal + abstract), monitored or unproctored assessments where stealth matters, and candidates who only need to pass one specific test without paying €49 for an unlimited pass they'll use once.
The key question: is your test purely abstract patterns, or does it include numerical/verbal sections? If it includes numerical or verbal, ReasonEra can't help — TestSolve is the only option. If it's purely abstract, both work, but TestSolve adds stealth and multi-model confidence that ReasonEra doesn't offer.
| Scenario | Best choice |
|---|---|
| SHL mixed assessment (numerical + verbal + inductive) | TestSolve — covers all sections |
| Matrigma or CCAT abstract-only test | Either — ReasonEra is specialised, TestSolve adds stealth |
| Proctored or screen-recorded test | TestSolve — phone delivery, invisible process |
| Unmonitored home test, abstract only | ReasonEra if you want unlimited, TestSolve if budget matters |
| Multiple abstract tests in 2 weeks | ReasonEra — unlimited pass is better value at volume |
| One assessment, mixed format, this week | TestSolve — $14.99 covers everything |
| Locked-down computer, no install allowed | Either — both have browser versions |
Technically yes, but ReasonEra shows the answer on your computer screen. If the test platform monitors tabs, screenshots, or browser focus, the ReasonEra tab is visible. TestSolve avoids this by sending answers to your phone.
No. ReasonEra specialises in abstract, logical, and inductive reasoning — pattern-matching tests like Matrigma, CCAT spatial, and Cognify. For numerical or verbal questions, you need TestSolve or manual preparation.
For heavy usage across multiple abstract tests, ReasonEra's €49 unlimited pass can be better value. For a single test with 30 questions, TestSolve is significantly cheaper at $14.99. Most candidates sit one test per employer.
ReasonEra claims 98% on Matrigma specifically. TestSolve achieves very high accuracy across all question types using multi-model consensus. On abstract reasoning alone, both perform well. On numerical and verbal, only TestSolve has coverage.
If your assessment has both abstract and mixed sections, you could use ReasonEra for Matrigma-style matrices and TestSolve for the numerical/verbal sections. In practice, most candidates find TestSolve sufficient for all sections.
