FluentTab

Language-learning assistant: select-to-translate on any site (local AI) and a realtime voice tutor for the language you learn.

FluentTab — Learn a language while you browse Turn every website into an interactive language-learning experience — with privacy built in from the start. FluentTab is a Chrome extension that helps you learn a new language naturally while you browse, read, study, or work online. Instead of interrupting your reading to look up translations or grammar, FluentTab brings everything directly into your browser: translations, pronunciation, grammar guidance, and an AI conversation partner. It supports learning German, French, Spanish, Italian, Portuguese, Dutch, English, Japanese, and Korean. Unlike many AI-powered language tools, FluentTab is designed with privacy as a core principle. Wherever possible, your learning happens entirely on your own device. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 LEARN A LANGUAGE WITHOUT GIVING UP YOUR PRIVACY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Most of FluentTab's features run locally on your computer. That means the words you highlight, the pages you read, and the grammar explanations you request are processed directly in your browser — not sent to external servers. This includes: • Instant translations • Noun genders and articles • Grammar explanations • Pronunciation • Conversation memory between study sessions Your reading habits stay yours. The websites you visit, the text you select, and your learning history remain on your device. When FluentTab does use cloud AI — for its optional voice conversation feature — it is designed so that your conversations are sent directly between your browser and the AI service. FluentTab's own servers never receive or store your voice conversations or transcripts. They simply verify your subscription and authorize access, without acting as a middleman for your conversations. In short: • Reading assistance stays on your device. • Voice conversations never pass through FluentTab's servers. • Your personal learning history remains private. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✨ FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ TRANSLATE ANY WORD OR SENTENCE Highlight any word, phrase, or sentence on virtually any website to instantly see: • A natural translation into the language you're learning • The meaning in your own language • The correct article for nouns • Context-aware explanations when you want to learn more No switching tabs or copying text into a separate translator. ▸ LEARN NOUN GENDERS INSTANTLY In languages that use grammatical gender — German (der / die / das), French (le / la), Spanish (el / la), Italian, Portuguese, and Dutch — FluentTab shows nouns with their correct article on supported learning websites, helping you build accurate vocabulary from the very beginning. ▸ UNDERSTAND GRAMMAR IN CONTEXT Hover over a translation to get a clear explanation of what's happening in the sentence, including grammar, word order, verb forms, cases, and vocabulary usage. Rather than memorizing grammar rules in the abstract, you'll understand them exactly where they appear in real writing. ▸ HEAR NATURAL PRONUNCIATION Listen to selected text spoken aloud with realistic voices to improve your listening skills and pronunciation while you read. ▸ PRACTICE SPEAKING WITH YOUR OWN AI TUTOR Whenever you're ready to practice speaking, FluentTab offers an interactive voice tutor. Ask questions, practice conversations, review grammar, or discuss the article you're reading — all in a natural conversation. Because the tutor understands the text you've selected, you can ask things like: • "What does this sentence mean?" • "Why does this word change form here?" • "Can you explain this grammar?" • "How would a native speaker say this?" The voice tutor is the only feature that relies on cloud AI, allowing for real-time conversations while preserving your privacy. Your conversations connect directly from your browser to the AI service, while FluentTab handles only account authentication and subscription management — not the conversation itself. ▸ LEARN CONTINUOUSLY After each conversation, FluentTab remembers the important points you've learned so your next study session feels like a continuation rather than a fresh start. These learning memories are created and stored locally on your device, giving you continuity without building a permanent cloud profile of your learning. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 💡 WHY FLUENTTAB? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Learn naturally while browsing the web • Translate words and complete sentences instantly • Master noun genders effortlessly • Get grammar explanations exactly when you need them • Listen to authentic pronunciation • Practice speaking with an AI tutor • Keep your reading activity and learning history private • Enjoy AI-powered learning without unnecessary data collection ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎯 PERFECT FOR ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Beginners building vocabulary • Intermediate learners mastering grammar • Advanced learners reading authentic content in their target language • Readlang users who want a richer learning experience • Anyone who wants to immerse themselves in a language while keeping control of their personal data ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⭐ SUBSCRIPTION ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FluentTab includes a free plan to get started, with premium plans available for learners who want extended access to the AI voice tutor and additional usage.
