Writing a novel, a short story, a script or a manuscript in English requires more than just good ideas. You need rhythm, structure, consistency, clean dialogue, believable characters and enough focus to keep writing chapter after chapter.
Grammar and spelling should not constantly interrupt that process.
If you write directly in a browser-based writing app like Plumelisse, you can use grammar checker extensions while drafting your text. These tools can help detect spelling mistakes, grammar issues, punctuation problems, repeated words, awkward phrasing and sometimes even tone or style problems.
Because Plumelisse works directly in the browser, compatible extensions for Chrome, Edge, Brave and Firefox can support your writing without forcing you to copy and paste your manuscript into another tool.
Here are some of the best English grammar checker extensions to consider, depending on your browser, your budget and your writing workflow.
Quick recommendation
- Grammarly: best all-round option for everyday English writing.
- ProWritingAid: best choice for fiction writers and long-form editing.
- LanguageTool: strong multilingual option, now mainly relevant as a paid browser extension.
- Ginger: useful for grammar correction and sentence rephrasing.
- QuillBot: good for grammar checking, paraphrasing and rewriting.
- Microsoft Editor: simple and convenient for Microsoft users.
- Hemingway Editor: not really a browser correction extension, but useful for style and readability.
Grammarly: the best all-round English grammar checker
Grammarly is probably the most widely known English grammar checker. It works well for everyday writing, emails, articles, essays, professional communication and creative drafts.
For authors writing in English, Grammarly can help identify spelling mistakes, grammar problems, punctuation issues and unclear sentences. It is especially useful during the first editing pass, when you want to remove obvious errors without stopping to analyze every line in depth.
Inside Plumelisse, Grammarly can be used as a writing assistant while drafting a chapter. It can point out small mistakes as you type, which makes it useful for authors who want a clean draft from the beginning.
Grammarly is particularly strong for general English. It is less specialized in fiction than ProWritingAid, but it is comfortable, fast and easy to understand.
Strengths
- Very easy to use.
- Strong everyday English correction.
- Useful for spelling, grammar, punctuation and clarity.
- Works well for emails, blog posts, notes and drafts.
- Good for writers who want fast, visible suggestions.
Limitations
- Some advanced suggestions require a paid plan.
- Not every suggestion fits a literary voice.
- It may sometimes make prose sound too neutral or corporate if you accept everything automatically.
- Brave is not officially supported by Grammarly, even if some Chromium-based behavior may work in practice.

ProWritingAid: the best option for fiction writers
ProWritingAid is one of the most interesting tools for authors writing fiction in English. It is not just a grammar checker. It also focuses on style, structure, readability, overused words, repetition and long-form writing patterns.
For novelists, that matters. A manuscript is not just a sequence of correct sentences. It needs pacing, variation, character voice and narrative flow. ProWritingAid is useful because it can help identify repeated words, sticky sentences, passive constructions, pacing problems and other issues that often appear in long drafts.
Inside Plumelisse, ProWritingAid can be a strong companion during revision. You can draft your chapters in Plumelisse, organize your notes and characters, then use ProWritingAid to refine the prose.
It is one of the best choices for English-language authors who want more than basic spelling correction.
Strengths
- Very relevant for fiction and long-form writing.
- Includes grammar, style and readability suggestions.
- Offers detailed writing reports.
- Useful for identifying repetition and weak phrasing.
- Strong fit for authors revising chapters or manuscripts.
Limitations
- Can feel heavier than Grammarly for simple everyday correction.
- Some advanced reports and features require a paid plan.
- The number of suggestions can feel overwhelming if you are still drafting.
- Best used during editing, not necessarily during the most creative first draft.
Best for
Authors writing novels, short stories, scripts or long-form fiction in English.

LanguageTool: a strong multilingual grammar checker
LanguageTool is a grammar, spelling and style checker that supports English and many other languages. It can be especially useful for bilingual or multilingual writers who switch between English and another language.
For English writing, LanguageTool can detect grammar issues, spelling mistakes, punctuation problems and some style concerns. It is also useful if you write in different varieties of English, such as American or British English.
One important point: LanguageTool’s browser extension is now mainly a Premium feature. Free users can still access the web-based grammar checker, but the browser extension is no longer the same free option it used to be.
Inside Plumelisse, LanguageTool can still be a good option if you are already a Premium user or if you want a multilingual writing assistant that works across different writing contexts.
Strengths
- Supports English and many other languages.
- Useful for multilingual writers.
- Detects grammar, spelling, punctuation and style issues.
- Can distinguish between English variants.
- Good alternative to Grammarly for users who write in several languages.
Limitations
- Browser extension access now requires Premium.
- Less fiction-focused than ProWritingAid.
- The free web checker is still useful, but less convenient than inline browser correction.
- Some advanced checks require a paid plan.
Best for
Writers who work in English and other languages, or who want a multilingual grammar checker inside the browser.

Ginger: useful for grammar correction and rephrasing
Ginger is an English writing assistant focused on grammar correction, spelling, sentence rephrasing and style improvement. It can be useful for writers who want help rewriting sentences that feel awkward, too long or unclear.
For authors, Ginger can be helpful during revision, especially when a sentence does not sound quite right. Its rephrasing features can suggest alternatives, which may help you find a cleaner or more direct version of a sentence.
Inside Plumelisse, Ginger can support everyday writing in English. It is particularly useful if you want a grammar checker that also offers sentence-level rewriting help.
Strengths
- Good for grammar and spelling correction.
- Includes sentence rephrasing.
- Useful for improving clarity.
- Works well for general English writing.
- Can help non-native English writers find more natural phrasing.
Limitations
- Rephrasing suggestions should be used carefully in fiction.
- It may make prose sound more generic if you accept suggestions blindly.

- Less specialized for long-form manuscript analysis than ProWritingAid.
Best for

QuillBot: good for grammar checking and paraphrasing
QuillBot is best known for paraphrasing, but it also offers grammar checking and writing assistance. It can be useful when you want to rewrite a sentence, simplify a passage or test different versions of a paragraph.
For authors, QuillBot should be used carefully. It can help you explore alternative phrasing, but fiction depends heavily on voice. A rewritten sentence may be grammatically correct but less personal, less rhythmic or less faithful to the character.
Inside Plumelisse, QuillBot can be useful as a complementary tool. You might use it to check a sentence, test a reformulation, or simplify a passage that feels too heavy.
Strengths
- Strong paraphrasing features.
- Includes grammar checking.
- Useful for rewriting and simplifying.
- Helpful for non-native English writers.
- Good for comparing alternative versions of a sentence.
Limitations
- Paraphrasing can flatten literary style.
- Not every suggestion preserves the author’s voice.
- More useful as a rewriting assistant than as a pure fiction editor.
- Some features require a paid plan.
Best for
Writers who want grammar checking plus paraphrasing and rewriting tools.

Microsoft Editor: simple and convenient for Microsoft users
Microsoft Editor is a practical option for users already working in the Microsoft ecosystem. It offers spelling and grammar suggestions and can be used through browser extensions.
It is not necessarily the most advanced tool for fiction writing, but it is simple and convenient. If you want a lightweight grammar checker that helps with basic English mistakes while writing online, it can be enough.
Inside Plumelisse, Microsoft Editor can be used as a simple correction layer while drafting. It is less specialized than Grammarly or ProWritingAid, but it can still catch common errors.
Strengths
- Simple to use.
- Good for basic spelling and grammar correction.
- Convenient for Microsoft users.
- Lightweight compared with more advanced writing assistants.
- Useful for everyday writing.
Limitations
- Less advanced for style and fiction writing.
- Fewer deep editing features.
- Not as tailored to long-form manuscripts as ProWritingAid.
- May be too basic for serious revision.
Best for
Writers who want a simple, lightweight English grammar checker and already use Microsoft tools.

Hemingway Editor: useful for style and readability
Hemingway Editor is not a traditional browser grammar checker extension in the same way as Grammarly or ProWritingAid. It is better understood as a readability and style tool.
It highlights long sentences, dense phrasing, passive voice and hard-to-read passages. For English prose, this can be useful during revision, especially if your writing tends to become too heavy.
For fiction, however, Hemingway should not be followed blindly. Literary writing is not always supposed to be short, simple and direct. Long sentences, rhythm and complexity can be part of your style.
Inside a Plumelisse workflow, Hemingway is better used after drafting. Write your chapter first, then use a readability pass to identify passages that may need simplification.
Strengths
- Useful for readability.
- Helps identify long or complex sentences.
- Good for simplifying heavy prose.
- Easy to understand.
- Helpful during revision.
Limitations
- Not a full grammar checker extension.
- Can push writing toward overly simple prose.
- Not always appropriate for literary style.
- Better as a complementary editing tool than as your main checker.
Best for
Writers who want to improve clarity and readability after drafting.

Which English grammar checker should you choose for Plumelisse?
If you want the best all-round browser extension for English, start with Grammarly. It is simple, polished and effective for everyday writing.
If you write fiction, novels or long-form manuscripts, ProWritingAid is probably the most relevant choice. It goes beyond basic correction and helps with style, repetition and structure.
If you write in several languages, LanguageTool is still a strong option, especially if you are willing to use the Premium browser extension.
If you want help rephrasing awkward sentences, Ginger and QuillBot can be useful, but they should be used carefully in fiction.
If you only need basic grammar and spelling support, Microsoft Editor may be enough.
If you want a readability pass after drafting, Hemingway Editor can help you identify heavy sentences and overly complex prose.

A good editing workflow for English writing
A grammar checker is useful, but it should not control your prose.
For fiction, the best workflow is usually:
- Write the first draft without correcting every sentence.
- Use a grammar checker to remove obvious mistakes.
- Review style suggestions manually.
- Keep the suggestions that improve clarity.
- Ignore suggestions that weaken the voice, rhythm or emotion of the scene.
- Do a final human reading pass before exporting or sharing your manuscript.
In a browser-based writing app like Plumelisse, this workflow is especially natural. You can write your chapters, organize your notes, keep track of your characters and use your preferred grammar checker extension in the same environment.
Conclusion
English grammar checker extensions can save time, reduce mistakes and make revision easier. They are not a replacement for your judgment as a writer, but they can help you produce cleaner drafts and more polished chapters.
For most writers, Grammarly is the easiest starting point.
For fiction authors, ProWritingAid is the strongest editing companion.
For multilingual writers, LanguageTool remains highly relevant.
For rewriting and phrasing help, Ginger and QuillBot can be useful.
For simple correction, Microsoft Editor is a lightweight option.
For readability, Hemingway Editor is a helpful complementary tool.
And if you write in Plumelisse, the main advantage is simple: your writing happens directly in the browser. That means you can draft, organize and revise your manuscript while using the grammar checker extension that best fits your English writing style.
