LexiBot IELTS Writing Checker

"Charging $15-30 per IELTS essay check is truly outrageous"
The cost of taking the IELTS is around $200, and preparation expenses range from $200 to $400. An additional fee of $15-30 per IELTS essay check is indeed excessive for students! What’s more, with such sky-high prices, the scores are still just estimates.
"IELTS and English should be accessible, not inflated!"
In some countries, language certifications, especially IELTS, are excessively priced, creating 'price inflation' that makes the costs of learning and practice tests incredibly high, rendering them inaccessible for most students like me. So, when will the goal of making English universally accessible truly be achieved? With the advancement of AI, I hope to see tools that support the learning and testing process at more affordable and reasonable prices.
"AI models like ChatGPT excel in English, making IELTS writing learning feasible!"
Some new AI models like ChatGPT, based on natural language processing (NLP), excel in English. I believe that with the right guidance, practicing, taking mock tests, and scoring IELTS Writing through AI will soon be achievable at much more affordable prices.

Frequently Asked Questions (FAQs)

How does LexiBot evaluate IELTS Writing

LexiBot has been trained to evaluate IELTS Writing based on the following four main criteria:

Task Achievement/Task Response – Addressing the task correctly

Coherence and Cohesion – Logical flow and connectivity

Lexical Resource – Vocabulary

Grammatical Range and Accuracy – Diverse and accurate grammar

Additionally, we have developed supplementary criteria to help you identify strengths and weaknesses, as well as to enhance the accuracy of the assessments for the main criteria. All of this is based on the official IELTS Writing Band Descriptors

Does LexiBot's evaluation of IELTS Writing differ significantly from actual scores?

Based on feedback collected from actual users of LexiBot, the average discrepancy is commonly +/-0.5 compared to real scores. However, in some test environments, there have been a few cases with a maximum discrepancy of +/-0.75. Therefore, please use the simulated scores as a reference only.

Why might LexiBot return different scores for the same essay?

IELTS Writing is an essay-based exam scored by human examiners, so you shouldn’t expect your level to be assessed with the absolute precision of a multiple-choice test. This is why essay-based exams often come with review services.

At LexiBot, we simulate scoring by rotating through multiple AI agents for each essay assessment, aiming to control the discrepancy to +/-0.5, and up to +/-0.75 at most, to ensure randomness and fairness.

However, if the discrepancy for the same essay is too large or unusual, please report it to LexiBot so we can provide timely solutions.

Are there any differences between the Unlimited plan and individual LC top-up packages?

The Unlimited plan and individual LC top-up packages both unlock the same Pro features; there are no differences between them.

Why are component scores for TR, CC, GRA, and LR given in decimal points (0.5)?

LexiBot acknowledges user feedback on this issue and fully understands the desire for component scores to align with IELTS format. However, LexiBot scores are divided into three levels (overall score, main component scores, and sub-component scores). Excessive rounding of component scores to whole numbers can lead to a higher overall score discrepancy. We have carefully considered this and, for now, the LexiBot team will maintain the current scoring format to ensure the lowest possible margin of error.

Is LexiBot developing any new features?

Yes, we continuously review user feedback submitted through the report form and via Live Chat. In the near future, our team will focus on improving the accuracy of the scores and developing new features based on user suggestions. If you have additional ideas, please take a moment to share them with us.

Common Issues & Solutions

LexiBot AI is running continuously but not providing results or delivering incomplete results

In most cases, this issue occurs due to an unstable internet connection. Specifically, if the connection is temporarily lost while fetching results, the connection to the AI may be completely interrupted, preventing further results from being returned.
If you encounter this issue, try the following:

Refresh the Page: Press F5 or refresh the page to reinitiate the connection.
Check Internet Connection: Verify your internet connection and ensure it is stable.
Switch Networks: Try switching to a different, more stable network if possible.

Issue Related to "Cookie Check Failed

This issue is related to cookies in the browser you are using, and we have not yet determined the specific cause. However, you can easily resolve it by clearing cookies for the LexiBot website using the following guide: How to Clear Cookies for a Specific Website

Additional Questions

Does LexiBot utilize ChatGPT for IELTS Writing assessment?

No, LexiBot has developed its own independent grading system for IELTS Writing, separate from ChatGPT or any other OpenAI models.

Can ChatGPT grade IELTS Writing?

Nope, even after a lot of testing this year (up to April), ChatGPT still doesn’t meet our standards for grading IELTS Writing.

How to detect unreliable IELTS Writing scoring websites?

Yes, it’s very easy to identify websites and AI models that are not capable of accurately scoring IELTS writing.

1. AI cannot detect if the essay has too many or too few words

Deliberately write an essay with either more or fewer words than required (150 words for Task 1 / 250 words for Task 2). If the tool fails to recognize this or provides a generic score with unstable feedback, the scores from this tool are unreliable.

If you are using a chatbot, you can refer to the following results:

ChatGPT Result
Google Gemini Result

Even though the essay contains 308 words, which exceeds the requirement, both chatbots stated that the essay did not meet the word count requirement.

2. AI cannot detect whether the essay is relevant to the topic

Deliberately write an off-topic essay or copy a random article from the internet that has no relevance to the IELTS writing topic. If the AI still gives a high score for Task Response / Task Achievement (greater than 4.0), the score from this tool is unreliable.

If you are using a chatbot, you can refer to the following results:

ChatGPT Result
Google Gemini Result

Both tools failed to recognize that the essay was entirely off-topic and even provided high relevance scores.

We conducted this simple experiment with various tools and found that AI on these websites could not fully understand the context of the test and lacked accurate guidelines, leading to scores that tend to be random or fabricated.

Use the scores provided by LexiBot as a reference to improve and track your progress, but do not over-rely on them.
