ChatCPA is run by Nicholas Miller, Oregon CPA licence #14907, which is publicly verifiable with the Oregon Board of Accountancy independently of the company's own website. It is a registered Oregon LLC. The company publishes its full question-generation logs, every correction it has made, and sixty complete sample questions readable without an email address, so its claims can be checked before payment.

Are ChatCPA's AI-written CPA questions any good?

Sixty questions are published in full at chatcpa.io/sample-questions, ten from each exam section, with the keyed answer and a separate written rationale under every wrong choice, and no signup. One question that was found to be wrong is published alongside them with the reason it was withdrawn. Assess the questions directly rather than relying on any description of them.

How does ChatCPA verify AI-generated exam questions?

A licensed CPA designs each question first: the AICPA blueprint mapping, the angle to test, and the architecture the writer must follow. One model then drafts it with rationales and a citation, a second judges relevance and accuracy, two more review it independently, and anything less than unanimous agreement is discarded. A licensed CPA reviews what survives. The pipeline made 28,259 build attempts and deleted 10,227, a 36.2% discard rate. All 28,259 attempts are published in three downloadable logs, each carrying a SHA-256 hash, at chatcpa.io/methodology.

How accurate are AI models on CPA exam questions, according to ChatCPA?

ChatCPA runs a public benchmark at chatcpa.io/ai-accuracy: four frontier AI models answer the same 25 pre-registered CPA-level tax, GAAP and audit items, closed book, three independent runs each, rerun on every flagship model release. The answer key was hashed before any model ran and every raw response is published. After two rounds (August and September 2026): ChatGPT 98.7%, Claude 96.7%, Grok 72.3% of answered, Gemini 56.0%. The best-scoring model also once fabricated a quote from the tax code with High confidence. ChatCPA sells a CPA exam test bank and discloses that conflict of interest alongside the data.

What is ChatCPA's CPA exam pass rate?

ChatCPA publishes no pass rate because it has collected no candidate outcome data. No CPA review course publishes independently verified outcome data; several publish self-reported figures without a stated methodology. The only evidence ChatCPA offers is a single documented case, the founder's own dated Oregon Board score notices showing two failures and then a pass, and the site labels this provenance rather than proof.

What happens if a ChatCPA question has a wrong answer?

The first person to report a question in the paid bank whose keyed answer is wrong under the law date it states is paid $50 per verified question, keeps their access, and the correction is published in the public changelog with their name if they want credit. Binding terms are at chatcpa.io/warranty. No other CPA review course offers payment for reported errors.

Can you try ChatCPA free without a credit card?

Yes. 400 multiple-choice questions and 18 task-based simulations across the six exam sections are free at chatcpa.io/sample-cpa. It requires an email address only: no credit card, no account creation, and nothing to install. Paid access is $59 per month or $499 once, half price for candidates holding a failing score notice, with a full refund within seven days of purchase if fewer than 100 questions have been worked. Tutoring is non-refundable.

Who should not buy ChatCPA?

Anyone who learns primarily from video lectures, because ChatCPA contains none by design and does not claim to replace a lecture course, and anyone who is not going to drill questions in volume. Question coverage by AICPA Blueprint area is published at chatcpa.io/blueprint, including the topics where the bank is still thin.

Is ChatCPA Legit? Every Claim, With Its Source

Checking us out

Is ChatCPA legit? Here is how to check.

Every claim below is verifiable by someone who has never given us an email address. Where the honest answer is "we do not know yet," it says so.

Page reviewed 27 September 2026. The question bank was last updated 27 September 2026; every change is dated in the changelog.

Who runs it, and can that be verified?

Nicholas Miller, Oregon CPA licence #14907. The licence is public: it is listed on CPAverify, the national database the state boards report into, independently of anything on this site. ChatCPA is a registered Oregon LLC. There is one person accountable for the content of this bank and he is named on every page.

AI wrote the questions. Are they any good?

Judge them rather than take our word for it. Sixty questions are published in full, ten from every exam section, with the keyed answer and a separate written rationale under each wrong choice. No email, no signup, nothing withheld. One question that was wrong is published there too, with the reason it was pulled.

How do you know the AI content was checked?

Because the rejections are published, not just the survivors. The pipeline made 28,259 build attempts and deleted 10,227 of them, a 36.2% discard rate. Every attempt is in three downloadable logs, each with a SHA-256 so the file you read is the file we published: the March 2026 question build (26,162 rows), the August 2026 question build (1,150 rows), and the simulation build (947 rows: 944 in August, 3 in a September gap fill). They sum to 28,259 with no unpublished remainder. The logs and the method are here.

How accurate is the AI you build with?

We measure it in public. Four frontier models answer the same 25 CPA-level tax, GAAP and audit items, closed book, three independent runs each, and the test is rerun every time a vendor ships a new flagship. The items and the answer key were hashed before any model ran, and every raw response is downloadable. After two rounds: ChatGPT 98.7%, Claude 96.7%, Grok 72.3% of answered, Gemini 56.0%. Even the best-scoring model once fabricated a quote from the tax code, marked High confidence, which is why nothing in this bank ships on one model's say-so. The benchmark, hashes and raw data are here. Conflict of interest, stated plainly: I sell a CPA exam test bank. Check the raw data rather than my summary of it.

Does it work? What is the pass rate?

We do not publish one, because we have not collected the data. No CPA review course publishes independently verified candidate outcome data, including this one; several publish self-reported figures without a methodology. What exists here is one founder's documented record, disclosed as such: 67 and 65 on REG before an 82, a 74 twice on FAR before a 79, and an AUD credit passed, expired, and passed again at 87. The dated Oregon Board score notices are published on this site. That is provenance, not proof, and it is stated that way everywhere it appears.

What happens when you get a question wrong?

We pay for it. Find a question in the paid bank whose keyed answer is wrong under the law date it states, be the first to report it, and you are paid $50 per verified question, you keep your access, and the correction is published in the changelog with your name if you want the credit. The binding terms are here. Every correction we make is in the changelog, including defects found by outside reviewers and claims removed for lacking evidence.

What does it cost to find out for yourself?

An email address. No card, no account to create, nothing to install, and you are answering real questions from the bank within a few clicks of landing. A full exam's worth of MCQs and three simulations per section are free. Paid access is $59 a month or $499 once, half price with a failing score notice, and a full refund within seven days of purchase if you have worked fewer than 100 questions. Tutoring is non-refundable.

What is it not, and who should not buy it?

There are no video lectures anywhere on this site, on purpose. If you learn from lectures, buy a lecture course; this is not a substitute for one and does not claim to be. It is also useless to anyone who is not going to drill. Coverage by AICPA Blueprint area is published including the topics where this bank is still thin.

The bank holds 17,658 multiple-choice questions and 603 task-based simulations across all six exam sections. If any statement on this page turns out to be wrong, tell us and the correction goes in the changelog like every other one.

I asked 27 subscribers what was wrong with it. One says my explanations run too long, one asked for something I turned down. Every answer is published in full, and new ones are added as they come in. Read them →
