Should I accept all suggestions automatically?

No — review corrections before accepting them, especially if you have intentional stylistic choices or domain-specific phrasing. The tool preserves your original voice and only makes corrections it identifies as errors, but for any change you are uncertain about, you can ask it to explain the correction before deciding. Selective review produces better output than batch-accepting everything.

How do I preserve my writing style while fixing errors?

The tool preserves your tone, voice, and intent by default. It only corrects errors, not stylistic choices. If you want to make this explicit, add a note to your request: 'Correct errors only, preserve my original style.' If the tool makes a change you consider a stylistic choice rather than an error, simply revert it or push back in the chat to have AI revert it.

Can I check content in multiple languages?

Yes. Submit text in any language and the tool checks grammar in that language, not just English. If you do not specify a language, it defaults to English. For multilingual documents with sections in different languages, check each section separately for the most accurate results.

What's the maximum length I can check at once?

There is no documented word cap on the free tier. For very long documents (i.e. articles over 3,000 words or full reports) breaking the content into sections (introduction, body, conclusion) tends to produce cleaner, more reviewable output than submitting the entire document as one block.

How do I use it alongside Hemingway or other tools?

Use them in sequence for complementary coverage. Run the AI Grammar Checker first to catch rule-based errors, such as grammar, punctuation, spelling. Then run FlowHunt's readability tool (or Hemingway, or a similar tool) to assess sentence complexity and passive voice. The two tools address different layers: grammar correctness versus readability and style. Running grammar correction first means your readability tool is analyzing clean text rather than flagging errors alongside style issues.

This FlowHunt grammar checker tutorial walks you through the complete workflow. For a conceptual overview of how the AI Grammar Checker compares to other tools and which content types benefit most, see the AI Grammar Checker vs Grammarly comparison , the full four-tool grammar checker comparison , and the 5 content types that need grammar checking before publishing . For ESL and non-native English writers, see the AI Grammar Checker for Non-Native English Writers guide. This guide covers the practical setup and the settings.

Step 1: Paste Your Text

Find the AI Grammar Checker in your app library and add it to your workspace. Then just paste your content into the chat interface. The tool accepts text in any format or structure, and returns the corrected version in the same structure.

By default, the tool takes pasted text. If you’d like to use URLs, Google docs or file uploads, the Agent can be easily adjusted. That way, you can run it automatically or at scale. For example, you can check your full library of past content to catch & fix any past mistakes.

What the tool checks in this pass:

Grammar — subject-verb agreement, tense consistency, incorrect word forms, and other structural issues
Punctuation — commas, apostrophes, periods, semicolons, and quotation marks used incorrectly or missing entirely
Spelling — misspelled words, typos, and incorrect homophones

For multilingual content, paste the text in its original language. The tool checks grammar in the submitted language without requiring any additional instruction.

Step 2: Specify Content Type and Formality Level

Before pasting your text, tell the tool what kind of content you are submitting and what standards apply to it. You ca do this the chat. A short instruction alongside your text is enough. If you’d like to send the same instructions in bulk, simply edit the agent’s prompt.

Style guide specifications:

"Apply APA format" — for academic or research content
"Apply MLA format" — for humanities or academic submissions
"Apply Chicago style" — for editorial or publishing contexts
"Use British English" or "Use American English" — for regional variant compliance

Formality and tone instructions:

"This is a professional business email so apply formal tone"
"This is a blog post so keep corrections consistent with a conversational register"
"This is a technical document so preserve domain-specific terminology"

If you provide no instruction, the tool defaults to a neutral, polished style consistent with what is already in your text. For most content, this default works well. Specifying context is most important when the content has a defined standard (academic, legal, style-guide-governed) or when you are working in a language variant where rules differ (British vs American punctuation conventions, for example).

Step 3: Review Grammar and Punctuation Suggestions

The tool returns your corrected text in the same format as your input. Read through the output and compare it against your original.

To get more from this step:

Ask the tool to explain any correction you did not immediately understand:

"Can you explain why you changed [phrase]?"
"What was the error in the original sentence?"

You can also ask it to highlight all changes made in the corrected version, which is useful when checking longer documents where changes could be scattered throughout.

For content where specific error types are the priority, narrow the scope:

"Check punctuation only"
"Check spelling and homophones only"
"Check grammar and ignore punctuation"

This targeted approach is useful for a second pass on content that has already been grammar-checked but needs a focused spelling review before publishing.

Step 4: Apply Style and Clarity Improvements

After the grammar pass, you can ask the tool to go further on style. This step is most valuable for content with strict style guide requirements or for ESL writers who want corrections explained rather than just applied.

Useful follow-up prompts:

"Are there any word form errors I should be aware of?"
"Is the tense consistent throughout?"
"Flag any sentences where subject-verb agreement is at risk"

The tool preserves your original voice in all corrections. If a suggestion changes meaning or removes something you intended, push back in the chat: "The original phrasing was intentional. Revert that change" or "Keep my original word choice here." The tool will adjust it.

For content that is grammatically clean but still reads as stiff or AI-generated, the AI Text Humanizer is the right follow-up: it rewrites the text for naturalness and conversational tone without changing the corrected structure.

Step 5: Final Review Before Publishing

Once you have accepted the corrections and applied any targeted improvements, do a final read-through of the complete text before publishing.

Final review checklist:

Skim every heading, subheading, and bullet point, because errors in structural elements are easy to miss in body-level review.
Read the first and last sentence of each section, as these carry the highest reader attention and errors here are the most damaging.
Check that any proper nouns, brand names, and product names are capitalized consistently. The grammar checker preserves your capitalization choices but does not enforce brand-specific standards it has not been told about.
If you added new content during the revision (expanded a point, added a data reference), run that new text through the checker separately before publishing.

Settings Guide for Different Content Types

Business email	`"Professional tone, American English, correct errors only"`
Blog post	`"Conversational register, American English, preserve my voice"`
Technical documentation	`"Preserve domain-specific terminology, American English, technical precision"`
LinkedIn post	`"Professional but direct tone, correct errors only"`
ESL / non-native writing	`"British/American English [specify], explain each correction"`
Multilingual document	Submit each language section separately with the target language stated

Common Issues and How to Handle Them

The tool changes a phrase you intended. Respond in the chat: "The original phrasing was intentional. Revert that change." The tool will restore it. If a pattern recurs, add "Correct errors only, do not change deliberate stylistic choices" to your initial instruction.

Technical or domain-specific terms are flagged. Add context upfront: "This is software engineering documentation, so preserve terms like [example]." LLM-based reasoning handles domain vocabulary better than rules-based tools, but explicit context produces the most accurate output.

The output contains too many changes to review efficiently. Ask for a focused pass instead of a full correction: "Punctuation only" or "Spelling and homophones only". Narrow the scope to what is most critical for the content type and run additional targeted passes as needed.

You are not sure whether a correction is an improvement. Ask for an explanation before accepting: "Explain why you changed this sentence." If the reason is a genuine rule the original violated, accept it. If it is a stylistic preference rather than an error, push back.

The text is in a language other than English. Paste the content without additional instruction. The tool checks grammar in the submitted language automatically. If you need a specific regional variant (European Portuguese vs Brazilian Portuguese, for example), add a one-line instruction specifying it.
