Grammarly is the most well-known English writing tool on the internet. But for many users — especially non-native English speakers — it falls short in a critical way: it fixes grammar, but it doesn't make your writing sound natural.
There's a big difference between "grammatically correct" and "sounds like a native speaker." Grammarly handles the first one well. The second one? Not so much. If you've ever had your Grammarly-edited email still sound a bit stiff or foreign, you know exactly what we mean.
In this guide, we've tested and compared 7 Grammarly alternatives in 2025 — covering different use cases, price points, and user types.

1. NativeProse — Best for ESL & Non-Native Writers
NativeProse is a Chrome extension built specifically for one thing: making your English sound like it was written by a native speaker. It doesn't just fix grammar — it rewrites your text to sound natural, fluent, and idiomatic.
The key difference from Grammarly: Grammarly tells you what's wrong and suggests minor fixes. NativeProse rewrites the whole thing from the ground up, choosing native phrasing and eliminating the subtle "foreign" patterns that non-native writers often don't notice.
It works in any text field in your browser — Gmail, Slack, Google Docs, LinkedIn — so you don't need to copy-paste anything.
Modes include: Native Rewrite (casual/formal), Academic, Professional, Simplify, and Translate (write in your language, get native English output).
- Makes text sound genuinely native, not just correct
- Works in any browser text field (no copy-paste)
- Multiple modes for different writing styles
- Very affordable — $4.9/month
- 10 free uses per day
- Chrome-only (no mobile app)
- Rewrites the whole text (not inline suggestions)
- No grammar explanation feature
Try NativeProse Free
10 free rewrites every day. No credit card required. Works in Gmail, Slack, LinkedIn, and any website.
Add to Chrome — Free2. ProWritingAid — Best for Authors & Long-Form Writers
ProWritingAid is the go-to tool for serious writers — novelists, content creators, and bloggers who write thousands of words at a time. It goes much deeper than Grammarly, offering 20+ different writing reports including pacing analysis, dialogue checks, and repeated sentence starters.
If you write long-form content and want detailed, in-depth feedback on your writing style, ProWritingAid is worth the investment. For casual users or email writers, it's overkill.
- Extremely deep analysis for long-form content
- One-time lifetime purchase option
- Integrates with Word, Scrivener, Google Docs
- Overwhelming for casual users
- Expensive ($20/month)
- Slow for short-form writing tasks
3. LanguageTool — Best Free Alternative
LanguageTool is the most capable free Grammarly alternative. It supports 30+ languages, which makes it useful for multilingual writers who switch between languages. The free plan is genuinely useful — not a bait-and-switch like some competitors.
It catches grammar and spelling errors well, and the premium version adds style improvements. It doesn't rewrite for "native-sounding" output, but for pure grammar correction it's an excellent free choice.
- Strong free plan (no word limit)
- Supports 30+ languages
- Open-source core (privacy-friendly)
- Doesn't improve naturalness/fluency
- UI feels dated
- Fewer style suggestions than Grammarly
4. Hemingway Editor — Best for Clarity
The Hemingway Editor is unique: it doesn't correct grammar, it highlights complexity. Long sentences, passive voice, adverbs, and hard-to-read sections are color-coded so you can simplify them. The goal is "Grade 6 readability" — clear, punchy writing.
It's useful as a final polish step for articles or blog posts, but it's not a day-to-day writing assistant. The web version is free; the desktop app is a one-time $19.99 purchase.
- Free web version
- Great for improving readability
- No subscription required
- No grammar correction
- Desktop app required for saving
- Too simplistic for professional writing
5. Wordtune — Best for Sentence Rewriting
Wordtune focuses on sentence-level rewrites, offering multiple alternative phrasings for any selected sentence. It's useful when you know what you want to say but can't find the right words. The free plan gives 10 rewrites per day, which is enough for light use.
The main limitation: it works sentence by sentence, not on full paragraphs. For rewriting a whole email or document, the process becomes tedious.
- Multiple rewrite options per sentence
- Good for finding the right phrasing
- Works in browser like Grammarly
- Sentence-by-sentence only
- Expensive at $13.99/month
- Free plan very limited (10/day)
6. QuillBot — Best for Paraphrasing & Students
QuillBot is primarily a paraphrasing tool, popular with students who need to rewrite text without plagiarizing. It offers 8 writing modes (Standard, Fluency, Formal, Creative, etc.) and integrates with Word and Chrome.
It's effective at paraphrasing, but the output can sometimes sound generic or slightly unnatural. It's better for restructuring existing content than for making writing sound truly native.
- Strong paraphrasing engine
- Good free plan
- Useful citation generator
- Output can sound generic
- Not great for making writing "sound native"
- Associated with academic dishonesty risks
7. Ginger — Best Grammar + Translation Combo
Ginger Software has been around since 2007 and offers grammar correction combined with a built-in translation feature for 60+ languages. It's one of the older tools on this list and shows its age a bit — the interface and AI quality haven't kept up with newer competitors.
The translation + grammar combination is unique, but NativeProse's Translate mode does the same job (write in your language, get native English output) with more modern AI.
- Grammar + translation in one tool
- Supports 60+ languages
- Text-to-speech feature
- Feels dated compared to newer tools
- Pricey for what you get
- Smaller community and fewer updates
Final Verdict: Which Should You Choose?
Here's the simple breakdown:
- Non-native English speaker? → NativeProse. It's the only tool built specifically to make your English sound native, not just correct.
- Writing novels or long articles? → ProWritingAid for the deep analysis.
- Just need grammar fixes for free? → LanguageTool.
- Student needing to paraphrase? → QuillBot.
- Want to improve readability of blog posts? → Hemingway Editor (free).
The core limitation of Grammarly — and most of these tools — is that they treat English as a fixed set of rules to follow. For native speakers, that's fine. For non-native speakers who've already internalized the rules but still don't sound native, you need something different. That's what NativeProse is built for.
