About FluentEditor

Built for the 1.5 billion people who write English as a second language

FluentEditor started from a simple observation: most grammar tools are built for native English speakers. Non-native speakers face a different set of challenges — regional phrasing patterns, missing articles, wrong prepositions, and unnatural sentence structures that spell-checkers never catch.

Our mission

When a software engineer in Bangalore writes an email, they know exactly what they want to say. The problem is not their knowledge — it is that the English phrase they learned may sound unnatural to a reader in New York or London. "Please do the needful" is perfectly understood in South Asian professional culture. To a Western reader, it signals a non-native speaker and can undermine the writer's credibility.

FluentEditor's mission is to close this gap — not by teaching people to write differently, but by giving them a silent AI co-pilot that translates their intent into English that sounds native. No more second-guessing. No more worrying about tone. Just clear, confident communication.

We believe writing is thinking. When you can write clearly, you can communicate more effectively, get your ideas taken seriously, and advance in your career. FluentEditor exists to make that possible for the 1.5 billion non-native English speakers in the world.

What FluentEditor specifically fixes

Unlike general grammar checkers, FluentEditor is trained on patterns specific to non-native speaker backgrounds. Here are the regional patterns we detect and rewrite:

🇮🇳South Asian English

"do the needful""revert back to me""out of station""at the earliest""prepone the meeting"

🇨🇳East Asian English

"I am agree""can able to""explain me"missing articles ("the", "a", "an")"discuss about"

🇸🇦Arabic / MENA English

"from your side""I am interesting in""Thank you on your help""make me a favour""as per your request kindly"

🇲🇽Latin American English

"make me a favor""I am very agree""explain me this""I hope you are well"literal translations from Spanish

🇵🇱Eastern European English

missing "the" and "a""I am working here since 5 years"wrong tense choices"I have went home"false cognates

How the AI works

FluentEditor uses a multi-model pipeline to route each request to the most appropriate AI model, balancing speed and quality.

Classifier routes your text

When you click Improve, a fast classifier model reads your text and determines the best task — rewrite, grammar fix, tone adjustment, or email draft. This happens in under 100ms.

AI model processes your request

Your text is sent to the most appropriate AI model: Llama 3.1 8B (fast, for grammar), Qwen 32B (balanced, for rewrites), or DeepSeek V3 (most capable, for complex tasks and email drafts). Models run on Nebius AI infrastructure.

Response streams back instantly

Results stream word-by-word to your screen in real time — no waiting for the full response. Typical response time is under 1.5 seconds for cloud AI, under 4 seconds for on-device WebGPU AI.

One-click replace in the page

Click Accept and FluentEditor injects the improved text directly into Gmail, Slack, LinkedIn, or wherever you are writing — no copy-paste needed.

Privacy by design: Your text is sent to the AI only when you click a button. We never store your writing content or use it for training. All processing happens server-side on Nebius AI infrastructure located in the EU. See our Privacy Policy for full details.
