Descriptive answer check

Drop a question and your answer — get marks, a criteria breakdown and the points you missed. Or go exam mode: timer on, paste off.

A strong answer addresses the exact question, supports its claim with relevant concepts, and explains how or why they matter. Before checking, ask whether a reader can follow each step of your reasoning. Small spelling slips matter less than missing ideas.

0 / 250 words

In checking mode, use feedback to find one change for your next attempt. In exam mode, plan briefly before writing and watch the clock and word count. This rehearsal cannot know every preference of your real examiner.

why it slaps

Marks, not vibes

Get a score out of your max marks with a criteria-wise breakdown you can actually argue with.

Missing points called out

See exactly which key points your answer skipped before the examiner does.

Word limit tracking

Live word counter that warns you the second you cross your limit.

Real exam pressure

Exam mode runs a countdown and auto-submits when time's up. No pausing, no vibes.

No paste, no spellcheck

The exam box blocks pasting and turns off spellcheck and formatting — just you and the paper.

Model answer included

Every check ends with a full-marks model answer written to your word limit.

Factual accuracy40%

Checks whether claims, definitions, dates, formulas, and conclusions are correct.

Example: Writing that photosynthesis uses light to convert carbon dioxide and water into glucose earns credit; saying it produces carbon dioxide loses it.

Concept & keyword match25%

Looks for the essential subject terms and concepts expected in a strong answer.

Example: For inflation, relevant ideas may include purchasing power, demand, supply costs, interest rates, and the consumer price index.

Analytical depth20%

Rewards explanation, connections, evidence, cause and effect, and justified conclusions—not just recalled facts.

Example: Instead of saying a policy failed, explain why it failed, what evidence supports that view, and which limitation mattered most.

Structure & flow10%

Checks whether ideas follow a clear order with focused paragraphs and logical transitions.

Example: A clear introduction, evidence-led body paragraphs, and a conclusion that answers the question score better than disconnected points.

Conciseness5%

Rewards direct, relevant writing that stays near the word limit without repetition or filler.

Example: One precise sentence explaining a cause is stronger than three sentences repeating the same point in different words.

Turn feedback into a rewrite

Look at deductions and missed points, then rewrite the weakest paragraph without the model answer. Compare versions and check factual claims against course material. Treat the AI score as practice feedback, not an official grade; follow your teacher's rubric if they conflict.

Study practice

Use answer feedback to improve your next draft

Written-answer practice exposes a different gap from multiple-choice quizzes: you must select relevant knowledge, organise it, and make the reasoning visible. The checker can supply a structured second look at your response. Treat it as formative feedback, not an official examiner, and compare factual claims and suggested improvements with your course sources.

A step-by-step study guide

  1. Choose an authentic question and its constraints

    Use a tutorial task, textbook prompt, or past-paper question you are allowed to use. Copy the complete wording, including command words such as 'explain', 'compare', or 'evaluate'. Enter maximum marks and the stated word limit. The checker takes a question and answer as text; it does not automatically read your textbook, lecture PDF, or official mark scheme.

  2. Write a first attempt before seeking feedback

    For a memory check, close your notes and draft the answer unaided. If you are learning a new topic, an open-book first draft is fine, but label it as such in your own records. Use your lecture notes to verify the final facts, not to silently fill gaps while pretending the attempt was closed-book.

  3. Check what the five pillars reward

    Review factual accuracy, concepts and keywords, analytical depth, structure and flow, and conciseness. Advanced settings let you adjust their relative weights while the total stays balanced. Align the emphasis with your course when you know it; changing weights cannot make the AI reproduce an official examiner's judgment or exact mark scheme.

  4. Read the reasons before the model answer

    Look at deductions, missed points, and strengths. Choose one or two concrete improvements, such as defining a key term or connecting evidence to a claim. Verify unfamiliar suggestions in your textbook. Read the model answer only after identifying your own revision targets, otherwise comparison can turn into copying rather than learning.

  5. Rewrite, then test the skill under time pressure

    Rewrite the weakest section without looking at the model answer, and check whether the change genuinely answers the command word. Later, try a related question in Exam mode with the real task's time and word constraints. Keep copies of your drafts outside the tool so you can compare reasoning, structure, and omissions over time.

The learning science behind the practice

Formative assessment closes a feedback loop

Feedback becomes formative when it informs a next action. A numerical mark alone does not tell you how to improve. Turn a comment into a task: if evidence is missing, add a relevant example and explain what it supports. Compare the revised answer against the original question. The value is in this loop, not in repeatedly requesting a higher AI score.

Focused practice beats vague repetition

Deliberate-practice principles emphasise specific targets, feedback, and repeated attempts at weaknesses. For written work, that can mean practising just a comparison paragraph or a concise explanation of a mechanism. Automated feedback is not equivalent to expert coaching, and merely writing many answers does not guarantee improvement. Seek instructor feedback when judgments remain unclear.

Retrieval and self-explanation work together

Writing without notes tests what you can retrieve; explaining why a fact matters makes the reasoning inspectable. For example, listing two causes is different from explaining how each produces an outcome. A model response may look familiar when you read it, so close it and reconstruct the argument later to check whether you can produce the reasoning yourself.

Worked study flow: a short economics explanation

Illustrative example, not an actual AI grading report. Imagine a 10-mark task with a 150-word limit: 'Explain two reasons why demand for a normal good may increase.' You want to improve causal reasoning rather than add more decorative wording.

Example first draft
'Demand rises when income rises and when people prefer the product. Businesses then sell more.' This identifies two ideas but leaves their mechanisms underexplained and does not distinguish demand from quantity demanded.
Likely revision targets
Check that income is connected to purchasing willingness and ability for a normal good. Explain how a change in tastes can increase willingness to buy at each price. Keep the other conditions constant and distinguish a shift in demand from movement along a demand curve. These are teaching targets, not a promised mark deduction.
A stronger core explanation
'For a normal good, higher consumer income can increase demand at a given price, shifting the demand curve right, other things equal. A favourable change in tastes can also increase willingness to buy at each price. Neither change is simply a movement along the curve caused by the good's own price.' Verify the terminology against your course text.
Transfer to a new question
After reviewing the feedback, answer a related prompt about an inferior good without looking at the example. If you can explain why the income relationship changes, you are practising the underlying distinction rather than memorising one response.

Record a revision target in concrete language: 'Explain the mechanism after naming each cause.' That is easier to practise than 'write a better answer'.

Study questions and troubleshooting

Can I upload a PDF or an official marking scheme here?

This page accepts the question and your written answer as text. Use your PDF notes or textbook outside the checker to verify content. The tool does not have automatic access to a course-specific mark scheme, so its feedback should not be presented as official marking.

How should I interpret the marks and grade?

They are AI-generated practice estimates based on the question, answer, and chosen settings. An instructor may apply different content requirements, conventions, or partial-credit rules. Use the reasons and missing points to guide revision; do not use the score as certification of exam performance.

What do the adjustable marking weights change?

They change the relative contribution of the five evaluation pillars. Increasing one automatically rebalances the others so the total remains 100%. Choose weights for a defensible learning purpose, such as focusing on analysis, rather than adjusting them repeatedly just to make a weak draft receive a higher score.

Does including more keywords guarantee a better answer?

No. Relevant terms must be accurate and connected to the question. A list of keywords without explanation may not show understanding. Use your course terminology where appropriate, then explain relationships, mechanisms, or evidence instead of inserting words only to satisfy an automated check.

What happens in Exam mode?

After you set the question, marks, word limit, and time, the countdown begins when you start. Paste and drop are blocked, spellcheck is disabled, and the attempt submits when time expires. There is no pause control. Practise first with a manageable task so you understand the conditions before a longer attempt.

Is the word limit a hard typing cutoff?

The page tracks your word count and warns when it exceeds the chosen limit; it does not simply stop you typing. Follow the actual task's limit and use feedback to practise trimming repetition. A limit of zero represents no specified word limit in the checking setup.

What if I disagree with a deduction or model answer?

Compare the disputed point with reliable course material and the exact question wording. AI can omit valid interpretations or introduce incorrect claims. Keep a note of the disagreement and ask a teacher when it affects assessed work. A polished model answer is not proof that every detail is correct.

Should I copy the model answer into my assignment?

No. Use it for comparison after making your own attempt, then write independently and follow your institution's AI and academic-integrity rules. If a task prohibits AI assistance, do not use this tool for that task. Learning from a practice example is different from submitting generated work as your own.

How can I improve without checking every tiny edit?

Choose one target from the first report, revise independently, and review the change against the question and textbook. Save a second check for a meaningful redraft or new question. This keeps attention on the skill being learned instead of chasing fluctuating scores from nearly identical submissions.

What should I do if checking fails?

Read the displayed error, check your connection, and confirm that both the question and answer are present with sensible numeric settings. Keep your draft in your own document before retrying. Do not rely on an open browser tab as your only saved copy of important work.
