I built a Chrome extension for ESL writers

Writing in English when it's not your first language is a constant low-grade stress. Every email, every Slack message, every doc review comes with a mental tax. Full disclosure: I built BeLikeNative, a free Chrome extension for real-time grammar and writing help. Take my perspective accordingly.

Why most grammar tools fall short for ESL writers

Standard spell-checkers catch typos. That's about it. They won't tell you that "I am agree with you" sounds wrong, or that "make a decision" is more natural than "do a decision." Non-native speakers don't just need red squiggly lines. They need context-aware corrections that explain why something sounds off.

I ran into this gap while talking with ESL learners who used browser tools daily. The corrections they got were shallow. Comma fixes, sure. But nothing about tone, word choice, or whether a phrase actually sounds like something a native speaker would write. That gap is what I set out to close.

Grammar and style corrections as you type

BeLikeNative runs in the background while you write. It catches the usual stuff (verb tense, subject-verb agreement, punctuation) but it also flags awkward phrasing and suggests alternatives. If you write "I have went to the store," it won't just underline "went." It'll suggest "have gone" and briefly explain the present perfect tense.

The style suggestions are where it gets more interesting. Say you're drafting a professional email and you write, "I want to ask you about the project." The extension might suggest "I'd like to follow up on the project," which reads more polished. These aren't generic rewrites. They're context-sensitive nudges that help you internalize better patterns over time.

There's also a paraphrasing feature. Highlight a clunky sentence and get alternative phrasings that keep your meaning intact. I've found this especially useful for people who tend to write the same sentence structures repeatedly.

Translation that understands context

One thing I didn't want to build was another word-for-word translator. Those exist everywhere and they're mostly useless for real writing. BeLikeNative supports over 80 languages, but the translations account for tone and cultural context. A formal request in Korean doesn't map directly to English, and the tool tries to bridge that gap.

You can draft in your native language and let the extension translate it into English. Then it checks the translated text for grammar and style, so the final result actually reads naturally. For reading, you can highlight unfamiliar words and get explanations of how they're used in everyday conversation, not just dictionary definitions.

Picking the right tone

Academic papers and WhatsApp messages don't sound the same. They shouldn't. BeLikeNative lets you adjust tone and style settings based on what you're writing. Switch to a formal mode for research papers, drop it to casual for a quick message to a friend.

I've seen students use the tone adjustment to learn the difference between registers. They write the same idea twice (once formal, once casual) and compare the suggestions. Turns out that's a surprisingly effective way to build intuition about English formality levels.

Where it works

The extension runs on Chrome, Firefox, and Brave. Edge support is coming. It integrates with Google Docs, Gmail, WhatsApp Web, Notion, and basically any text field in your browser. You don't need to copy-paste text into a separate app.

Keyboard shortcuts make it faster. Highlight text, hit the shortcut, and get corrections without leaving your current tab. Clipboard integration means you can refine text from any source with a couple of keystrokes.

Setup takes about a minute

Install from the Chrome Web Store, click the icon in your toolbar, set your language preferences and preferred tone. That's it. The extension starts working immediately in whatever text field you're typing in.

You can use it four ways: type directly and see real-time suggestions, highlight existing text for analysis, use built-in prompts for specific tasks, or paste content into the extension window. Most people start with the real-time suggestions and discover the other modes over time.

Pricing

The free tier gives you basic grammar and spelling checks with a 1,000-character limit per session. It's enough to get a feel for how the tool works.

For $4/month, the Learner plan bumps you up to 25 daily uses and 10,000 characters, with keyboard shortcuts and editable suggestions. The Native plan ($6/month) adds 50 daily uses, priority bandwidth, and a voice in future development. At the top, the Premium plan ($14/month) gives heavy users 125 daily uses and perks like partnership opportunities and a potential lifetime license option.

I kept the free tier genuinely useful on purpose. If you're a student on a budget, you can still get real value from it without paying anything.

What's next

I'm working on improving the contextual suggestions and expanding the translation engine. The goal isn't to replace language learning. It's to make the daily writing that ESL speakers already do into a learning opportunity itself. Every correction is a small lesson, and those add up.
