AI & Automation Tools
These two writing tools handle the difference between text that is wrong and text that is merely clumsy. Students, non-native English writers, marketers and anyone sending work to a client will use one or the other before pressing send. The Grammar Checker reads a passage and flags errors of correctness: agreement between subject and verb, tense slips, misplaced punctuation, missing articles and the spelling mistakes a dictionary alone will not catch because the wrong word is still a real word. It is the last pass before publishing, and the one that protects you from the mistakes readers notice first. The Text Paraphraser rewrites a passage in different wording while keeping the meaning. That is useful when a sentence is grammatically fine but reads awkwardly, when you want a formal draft to sound plainer, or when you need to express a source in your own words rather than quoting it. Always read the result rather than accepting it, because rephrasing can shift emphasis and a paraphrase of someone else's work still needs a citation. A sensible order is to paraphrase first, while the wording is still in flux, and to run the grammar check last on the version you intend to send.

Text Paraphraser
Rewrite text with a synonym engine offering four tones, three rewrite strengths and highlighted changes.
Grammar Checker
Check text for misspellings, missing apostrophes, repeated words and spacing errors, with a marked-up diff.
The correction passes and what each one looks for
The spelling pass matches words against a dictionary of common misspellings and their corrections, so accomodate becomes accommodate and definate becomes definite. The contraction pass restores missing apostrophes in forms that are not themselves real words, which is why dont and wouldnt are fixed while ambiguous cases such as were and cant are deliberately left alone rather than risking a wrong guess.
A phrase pass rewrites set errors and wordy constructions: could of to could have, more better to better, anyways to anyway, due to the fact that to because. A repeated-word pass finds any word immediately duplicated and drops the second copy. An article pass switches a to an before vowel sounds and back again before consonant sounds, with exception lists so a university and an hour stay correct. Final passes normalise spacing around punctuation, collapse double spaces and capitalise the first word of each sentence.
Identical issues are then grouped together with a count, so one error repeated six times appears once.
Worked example: a short paragraph with six issues
The capitalisation pass raises the opening i to I. The contraction pass fixes dont to don't. The phrase pass rewrites could of to could have. The repeated-word pass finds two duplications, the the and a a, and removes the second copy of each. The article pass changes a hour to an hour, since hour begins with a silent h and takes an. The spelling pass corrects definately to definitely, and the spacing pass removes the space before the comma and before the full stop.
The corrected output reads: I don't think we could have finished the report in an hour, and it's definitely a good result.
The issue list would show these grouped by type: one capitalisation, one punctuation for the apostrophe, one grammar entry for could have, a repeated word entry covering both duplications with a count, one grammar entry for the article, one spelling entry, and spacing corrections. The word count of the original and the total issue count appear above the result.
What a rule-based checker can and cannot see
The important limit is that these are pattern rules, not an understanding of your sentence. The checker cannot tell you that a sentence is ambiguous, that a paragraph contradicts the previous one, or that a technical term is wrong in context. It will not catch a correctly spelled word used in the wrong place, such as their for there in a construction its rules do not cover, and it does not attempt subject-verb agreement or tense consistency across a passage.
Some cases are left untouched on purpose. Ambiguous contractions are skipped because guessing would introduce errors, and style suggestions such as shortening in order to are flagged as suggestions rather than errors because they are sometimes the better choice. Proper nouns, deliberate dialect, creative writing and quoted material may all be flagged wrongly, so keep the original if the change would alter someone's actual words. Text longer than roughly 2,500 words needs to be checked in sections.
