How to Check Spelling and Punctuation Using "AI proofreader"

Prepare the Source and Define Editing Boundaries

Copy the fragment you want to check and save the original version separately. The main text field accepts up to 8,000 characters. If the material is longer, divide it by meaning—for example, into introduction, main body, and conclusion. Do not split a sentence or list in the middle, as this makes it harder for the model to understand context.

Before launching, decide whether you need only error correction or also light stylistic editing. For legally significant messages, quotations, or artistic dialogue, preserving original phrasing is especially important. Names, dates, numbers, and offer conditions should be listed as items that must not be changed. Do not add personal data or confidential information to the request.

Formulate Your Preferences in the Additional Details Field

The form includes fields for the source text and additional preferences. There are no preset editing modes or sliders for change intensity—constraints must be specified in plain text. For example, ask to correct spelling and punctuation, preserve a conversational tone, avoid adding new facts, and not change specified numbers.

The more precise the instruction, the easier it is to verify the result. A request like "make it better" allows many interpretations, while "fix errors, keep short sentences, and preserve the ‘you’ address" sets clear boundaries. If you want explanations for corrections, you can include that in preferences; the service does not provide an automatic version comparison report.

Preferences: "Correct spelling and punctuation. Keep a friendly tone and the ‘you’ address. Do not change the date October 15, the 10% discount, or the delivery condition. Do not add promises."

Test the Tool on a Short Fictional Example

Start with a small message where expected corrections are clear. In the example below, there are agreement and spelling errors. The date and discount size are explicitly set so you can verify their preservation after generation. This is a training example of a possible result, not a description of a real promotion.

Select the output language and click the generation button. The response appears in a separate panel. Speed depends on queue and availability of the free model, so do not expect fixed processing time. If the result is unsatisfactory, refine the source or preferences and run the tool again.

Source: "Наша команда рады сообщить: 15 октября мы открываем новый магазин. Первые покупатели получит скидку 10%. Доставку оплачивает покупатель".
Possible correction: "Наша команда рада сообщить: 15 октября мы открываем новый магазин. Первые покупатели получат скидку 10%. Доставку оплачивает покупатель".

Compare Facts, Meaning, and Authorial Tone

First, compare numbers, dates, names, and conditions. In our example, these should remain: October 15, 10% discount, and delivery paid by the customer. If the model added free delivery or changed the discount size, the version is unsuitable, even if it sounds convincing and grammatically correct.

Then read each revised sentence. Check who performs the action, who the message is addressed to, and whether the original degree of certainty is preserved. Phrases like "we plan to open" and "we will open" are not equivalent. Separately evaluate tone: friendly text should not become a solemn advertising promise without your request.

Manually Refine Ambiguous Areas

The model may not recognize intentional colloquial forms, jokes, dialects, or professional terms. If an unusual expression is important to the author’s voice, explain this in preferences or restore it manually. Grammar checking does not replace fact-checking: dates, names, and product details must be verified against your source materials.

After editing, read the text aloud or take a short pause and reread it. Ensure the message is understandable without extra context and contains no ambiguous promises. For important documents, a separate human review by someone familiar with the topic and aware of which phrasings must be preserved is helpful.

Copy or Download the Final Text

In the result panel, you can copy the text or download it as a TXT file. If the material needs to be formatted in a document, paste it into your editor and set headings, indentation, and lists there. The service does not create DOCX files or send publications or emails on your behalf.

Keep the source and chosen final version side by side. This allows quick restoration of phrasing if a meaning error is later discovered. Before sending to the recipient, check the inserted text: line breaks and formatting may differ in email clients, messengers, or publishing systems.
