# An AI exam assistant built for understanding and verification

ExamNinja helps with permitted exam preparation, practice questions, homework, and answer review. It suggests an answer, explains the reasoning, and identifies limitations; it does not take an exam for you or bypass assessment controls.


## What an AI exam assistant should do

An effective assistant should reduce the time between finding a difficult question and understanding the relevant concept. ExamNinja works with supported text-based questions and separates the proposed answer from the reasoning and caveats.

| Study task | Useful ExamNinja workflow |
| --- | --- |
| Practice quiz | Compare the suggested answer and explanation with your attempt |
| Multiple-choice review | Evaluate every supplied option and the prompt's qualifiers |
| Homework question | Work through a focused sequence, then reproduce it independently |
| Answer verification | Check your proposed response for missing conditions or reasoning |
| Exam preparation | Review weak concepts with permitted questions before the assessment |

## How it works in Chrome

1. Install ExamNinja and sign in with an email code.
2. Open a supported practice or review page and choose one permitted question.
3. Read the proposed answer and explanation, then verify important work against your course material.

The actual Chrome shortcut appears during onboarding and can be changed in Chrome's extension-shortcut settings.

## AI exam assistant versus AI exam taker

An assistant keeps the student responsible for reading, deciding, and verifying. An “AI exam taker” suggests autonomous completion or prohibited real-time assistance. ExamNinja does not log into an assessment, submit responses, impersonate a student, defeat secure browsers, or promise correct results.

## Supported formats and boundaries

Text-based multiple-choice, multiple-select, fill-in-the-blank, short-answer, and focused homework questions are the strongest fit. Support depends on the page structure and course configuration. Diagrams, custom widgets, image-only prompts, secure browsers, and separate proctoring systems may not work.

## ExamNinja versus copy-and-paste chatbots

| Workflow detail | ExamNinja in Chrome | General copy-and-paste chatbot |
| --- | --- | --- |
| Question context | Reads the selected supported question after you activate it | Depends on what you manually copy |
| Result structure | Separates likely answer, explanation, steps, and limitations | Varies by prompt and product |
| Study flow | Keeps the explanation beside the permitted practice page | Requires switching tabs or windows |
| Verification | Links the workflow to a repeatable source-checking process | Usually requires you to create your own process |

## Frequently asked questions

### What is an AI exam assistant?

An AI exam assistant helps explain, solve, or review permitted practice questions. The student remains responsible for applying course rules and verifying the generated response.

### Is an AI exam assistant the same as an AI exam solver?

The phrases overlap in search. ExamNinja uses “assistant” to emphasize explanations and verification rather than automatic exam completion.

### Does ExamNinja take exams for students?

No. It does not impersonate students, submit an assessment, bypass secure browsers, or guarantee correct answers.

### How many free answers are included?

The current free plan includes five successful answers per day after email sign-in. Product limits can change, so the account interface is the current source of truth.
