The service allows you to check the grammar, spelling and punctuation of English text. You can choose another language on the website's main page. We recommend checking spelling first, then punctuation.

Users without registration can check texts up to 1000 characters in length, while registered users can check texts up to 1500 characters. The Pro version allows you to check texts up to 100,000 characters in length, has a separate queue, and disables ads.

Spelling check

After the spelling check, possible errors are highlighted in yellow. You can click on the highlighted words for detailed information and to choose from correction options. Click on the appropriate option to correct the error in the text.

Punctuation check

The punctuation check corrects up to 80% of possible errors in punctuation marks. After the check, the marks are highlighted in different colors:

  • Orange - the program changed a capital letter in the word,
  • Red - there is a high probability of an error in this mark,
  • Yellow - a new mark has been inserted where there was none before,
  • Green - the program agrees with this mark.

By clicking on a mark, you can remove it from the text. By clicking on an orange word, you can return it to lowercase. Punctuation changes the meaning of the text, so make sure to place marks correctly!

Mobile applications for android and ios.

Automatic punctuation placement

The service enables automatic placement of punctuation marks in the text: commas, periods, dashes, colons. This allows you to quickly type the text for subsequent use.

Properly placed punctuation marks help to accurately understand your written speech.

Thanks to punctuation, we place necessary emphasis on important details.

If you were to write a text without using any punctuation marks at all, it would turn into a mess.

Pauses (commas, periods, ellipses), emotions (exclamation and question marks), uncertainties – here is a short list of feelings expressed through punctuation.

The basic rules of punctuation in English

Period (.): Used to end a declarative sentence or statement. Also used in abbreviations.

Example: She went to the store. Dr. Smith

Comma (,): Used to separate items in a list, set off introductory phrases, and to separate independent clauses when joined by a coordinating conjunction (and, but, or, nor, for, so, yet).

Example: I like apples, bananas, and oranges. Before going to bed, she always reads a book.

Question Mark (?): Used to end a direct question.

Example: Where are you going?

Exclamation Mark (!): Indicates strong emotion, excitement, or emphasis.

Example: Wow! That was amazing!

Colon (:): Used to introduce a list, explanation, or quotation.

Example: There are three colors in the flag: red, blue, and green.

Semicolon (;): Used to connect closely related independent clauses without a conjunction.

Example: She likes coffee; he prefers tea.

Quotation Marks (" "): Used to indicate direct speech or to enclose titles of shorter works.

Example: She said, "I'll be there in a minute." The short story is titled "The Lost Key."

Apostrophe ('): Used to indicate possession or to form contractions.

Example: Jane's book is on the shelf. They're (they are) coming.

Hyphen (-): Used to join words in a compound, to separate syllables in a word, or to clarify meaning.

Example: well-known, twenty-five, re-create

Parentheses (()): Used to enclose additional information or comments within a sentence.

Example: The meeting (which was scheduled for 3:00 PM) has been postponed.

Ellipsis (...): Indicates omitted words or a pause in speech.

Example: "I thought you were... never mind."

Dash (—): Used to emphasize or set off information within a sentence.

Example: She completed the assignment—despite the challenges.

Remember that these are general rules, and there may be specific cases or exceptions. It's always good to refer to a style guide or grammar resource for more detailed information.

The basic rules of spelling in English

  • i before e except after c: This rule is a helpful guideline for spelling words with the vowel combination "ie" or "ei." However, there are many exceptions to this rule, so it's not foolproof. Example: believe, receive (exceptions: science, efficient)
  • Silent 'e': When a word ends with a silent "e," it often makes the preceding vowel long. Example: kite, hope (the "e" at the end affects the pronunciation of the preceding vowel)
  • Doubling final consonant before -ing or -ed: When adding -ing or -ed to a word that ends in a single consonant preceded by a single vowel, double the final consonant. Example: run (running), hop (hopped)
  • Drop final 'e' before a suffix that begins with a vowel: When adding a suffix that begins with a vowel to a word ending in a silent "e," drop the final "e." Example: bake (baking), hope (hoping)
  • Changing 'y' to 'i' before a suffix: When a word ends in a consonant followed by a "y," change the "y" to "i" before adding a suffix (except when the suffix begins with "i"). Example: happy (happiness), baby (babies) 
  • Plurals: Add -s to form the plural of most nouns. Add -es to nouns ending in s, x, z, ch, or sh. Example: cat (cats), box (boxes), buzz (buzzes)
  • Irregular plurals: Some nouns have irregular plural forms. Example: man (men), child (children), mouse (mice)
  • Common prefixes and suffixes: Understanding common prefixes (e.g., un-, dis-, pre-) and suffixes (e.g., -ly, -tion, -able) can help in spelling various words. Example: unhappy, disconnect, preheat, quickly, celebration, capable
  • Homophones: Be careful with words that sound the same but have different spellings and meanings. Example: their, there, they're; to, too, two
  • Exceptions: English has many irregular words and exceptions to the rules. Learning them through practice is crucial.

These rules provide a general foundation for English spelling, but it's important to note that there are exceptions and variations. Regular reading and exposure to words in context can greatly enhance spelling skills.

The basic rules of grammar in English include

  • Subject-Verb Agreement: Ensure that the subject and verb in a sentence agree in number (singular or plural). For example, "He walks" (singular) versus "They walk" (plural).
  • Punctuation: Use appropriate punctuation marks, such as periods, commas, question marks, exclamation points, colons, and semicolons, to convey meaning and structure sentences correctly.
  • Sentence Structure: Construct well-formed sentences with a clear subject, verb, and object. Avoid sentence fragments and run-on sentences.
  • Tenses: Use appropriate verb tenses to indicate the timing of actions or events. Common tenses include past, present, and future.
  • Parts of Speech: Understand and use different parts of speech, including nouns, verbs, adjectives, adverbs, pronouns, prepositions, conjunctions, and interjections.
  • Articles: Use articles (a, an, the) correctly to specify or limit a noun.
  • Modifiers: Place modifiers (adjectives and adverbs) in appropriate positions to provide clarity and precision.
  • Parallelism: Maintain parallel structure in lists and comparisons, ensuring that similar elements are presented in a consistent grammatical form.
  • Concord (Agreement): Ensure that elements within a sentence, such as pronouns and their antecedents, agree in gender, number, and person.
  • Capitalization: Capitalize the first word of a sentence, proper nouns, and proper adjectives.
  • Spelling: Spell words correctly to convey the intended meaning.
  • Consistency: Be consistent in style, tense, and point of view throughout a piece of writing.
  • Apostrophes: Use apostrophes to indicate possession and to form contractions.
  • Subject and Object Pronouns: Choose the correct subject or object pronoun based on its role in the sentence (e.g., "he" as a subject and "him" as an object).
  • Comma Usage: Employ commas to indicate pauses, separate items in a list, set off introductory elements, and separate coordinate adjectives.

These are foundational rules, but English grammar can be complex, and there may be exceptions or additional nuances to consider. It's also important to be aware of variations in grammar rules between different English-speaking regions.
