Quality control by AI analysis of 10 official workbooksAll the philosophy and design built over about a year without any compromise.
English is the infrastructure of global business. However, high-quality learning materials are expensive and out of reach for learners in many countries.
AI can break down this barrier. FREE TOEIC can be delivered worldwide, and costs decrease as more people use it.
TOEIC questions are "business conversations." They are excellent learning materials even for non-test takers. Immersing yourself in 60 minutes of new business English daily provides stimulation equivalent to doing business in an English-speaking country.
And this, for free. However, it's meaningless if the quality is low. It has no value unless it's equal to or better than the official TOEIC.
If you ask an AI to "create TOEIC-style questions," it will produce something that looks plausible. But in reality:
The paraphrase rate is 0%. The correct answer choice becomes a verbatim copy of the conversation text, so you can find the correct answer just by looking at the text even if you can't hear it. In the official TOEIC, most correct answers are paraphrased (reworded). AI doesn't know this.
The traps are ineffective. Incorrect answer choices are created randomly, and no one falls for them. Official TOEIC incorrect answers contain intentional traps like "using words from the conversation to lead to a different meaning" or "plausible but not supported by the audio." AI doesn't know this.
The correct answer positions are biased. AI tends to place correct answers in B or C, not achieving an even distribution like the official test.
Approval specification V172.21. A question generation system completed after over 2000 revisions.
After AI generation, questions go through 55 stages of automatic quality checks. If any stage fails, the question is regenerated or discarded. The free questions delivered to you cost 100x more (compared to initial specification v1, token consumption per question generation) than the questions initially generated by AI.
Final shipping quality assurance is also strict. Questions must pass the four-stage check system of DeepSeek, Gemini, ChatGPT, and Claude to be shipped as questions.
The foundation supporting quality is the AI, condensed from a year of prompt engineering, and the multi-stage quality pipeline.

FREE TOEIC analyzes and reproduces the official TOEIC workbooks, from the number of words per minute of conversation to changes in total word count from the beginning to the middle and latter parts.
This not only means the conversation speed almost matches the real TOEIC test, but also finishes the questions with the same rhythm and tempo as the real test.
From French, German, Spanish, and Portuguese to Arabic, Hindi, Thai, Vietnamese, Japanese, Korean, Chinese, and Swahili. People worldwide can challenge English questions for free. Checking translations and traps in your native language costs only $3.99. This cost is derived from the price of a KFC set menu in Kenya. An environment where anyone in the world can learn. And making that cost the global standard price. That is the belief of FREE TOEIC.
FREE TOEIC is a system built by one engineer over about a year while conversing with AI. The initial conversation partners were Gemini, ChatGPT, DeepSeek. And from summer, Claude. It was a year of continuously building quality while switching between AIs.
Hearing "free questions made by AI," it's natural to think the quality is low. In fact, most AI-generated questions in the world are of low quality.
That's precisely why we achieve quality control surpassing humans through 55 stages of quality checks, AI refined through over 2000 revisions, and vast diversity patterns. We scientifically analyze official TOEIC workbooks, reproduce them with numbers, and guarantee them with code.
Commercial workbooks cost 2,000 to 3,300 yen (official) for just 2 sets. FREE TOEIC continuously delivers over 1 hour of new daily materials (PART2, PART3, PART4, shadowing) 1 set for free. We do not compromise on quality, nor do we compromise on quantity.
We will break the common sense that "free means low quality" with the power of code.That is FREE TOEIC's commitment.
You can experience all features of the first set (3 questions) with the FREE plan.
