Mocko.ai not good for TEF preparation. ⚠️ Broken AI Service & No Customer Support [Update: I successfully got all my money back via bank dispute.] I spent $202.72 on Mocko.ai(purchased in Dec, 2025) for TEF preparation, and it is a total failure. The AI is broken — it marks correct answers as "Wrong" even when they match the audio perfectly. The product does not do what it promises. My Evidence (Screenshots: https://drive.google.com/drive/folders/1GgneM32b3BEMZd7P82tjxnYgDwV37N2_?usp=sharing): 1. 100% Error Rate: I did 5 random tests. Each time, I answered only the first listening question, recorded the audio, took a screenshot then went to result. Every single time, the AI marked my correct answer as "Wrong." 2. Unable to review any listening question in mock exam: The review page crashed with a coding error: "Something went wrong while showing your report. examContext.Provider is missing!" 3. No Correct Answers Provided: In the listening mock exam, the system flags your answers as "Wrong" but doesn't tell you the correct answers. 4. Inaccurate Grading: I recorded a full listening test in mock exam and converted the audio to text. The AI claimed I got 29 wrong (especially a weird pattern from Q3 to Q14). I compared these with ChatGPT and Gemini, and both confirmed that my answers should be 29 correct and 11 wrong. -

This is awesome. It tells me the answers to my practice exam questions automatically through my airpods without me having to do anything, just by seeing my exam through my phone camera. I've been looking for an AI tool like this for a while.

I am honestly impressed by the quality of questions generated. Looks better than the other study tools so far.

Smartexam is disappointing compared to other quiz tools. The paid version is more expensive than competitors but lacks key features. It doesn’t adapt to different student skill levels, offers no tutoring support, and you can’t navigate back and forth during quizzes. Also, the answer format makes it too easy to guess the correct choice. Not worth the price.

I've tried a few essay grading AIs and Examino is the best one in my opinion. Easy to use, great at handwritting recognition, and provides useful feedback to the students
