A grammar checker built for people who think in another language.

Lingently is a grammar checker for non-native English speakers, on Android. It catches the mistakes that come from translating your first language word for word, explains the rule behind each fix in one line, and turns your fixes into short daily practice. It floats over WhatsApp, Gmail and any app, so you check the message where you write it.

Your mistakes have a pattern

If English is your second language, your mistakes aren't random. They follow the grammar of the language you think in. A Spanish speaker writes "I am agree" because Spanish says estoy de acuerdo. A German speaker writes "since three years" because German says seit drei Jahren. Every word is a real English word, so a spell checker lets it through.

That's the kind of mistake Lingently is built to catch.

It explains the rule, not just the fix

Each correction comes with one short line on why. You can choose to read the explanations in English, Spanish, French, German or Portuguese. Pick your own language while you're learning, and switch to English when you're ready.

It turns your fixes into practice

A grammar checker that only fixes things keeps you dependent on it. Lingently saves every fix and builds practice from it:

• Redo your own sentences. A few minutes a day, you fix the exact line you got wrong.
• See your patterns. Prepositions, verb forms, articles: which keep coming back, and which you've beaten.
• A word bank that grows from your own fixes.

Over time you need the checker less. That's the point.

Made for real messages

People who write in a second language often write the important things in it: a message to the boss, an email to a landlord, a cover letter for a recruiter, a note to a child's teacher. Lingently works in the apps where those get written. Tap the character, read the fixes, tap Replace.

What it checks

• Apps: WhatsApp, Gmail, Slack, LinkedIn, Messenger, your browser and most apps where you type.
• Privacy: it reads only the text field you're typing in, only when you tap. Your text is checked, then deleted. Never passwords or SMS.
