How It Works

Three steps to fluency

STEP 01

Adaptive Assessment

Take a short AI-powered proficiency test that adapts in real-time, getting harder or easier based on your answers, to pinpoint your exact CEFR level across all 6 skill areas.

STEP 02

Personalized Learning

Get AI-generated lessons, exercises, podcasts, and conversation practice tailored precisely to your weak areas and current level. Every session is unique and no two users see the same content.

STEP 03

Track & Master

Watch your CEFR level rise with skill radar charts, streaks, and achievements. SM-2 spaced repetition turns every mistake into a scheduled review so you never forget again.

Smart Practice

Weakness-First Practice

Generate fresh practice sets across grammar, vocabulary, reading and writing, always with your weakest skill first. A separate practice score charts your progress without ever putting your official CEFR level at risk, and every correct answer earns XP. Low-pressure reps whenever you want them.

Vocabulary

Smart Vocabulary

AI generates contextual definitions, examples, and pronunciation. SM-2 spaced repetition schedules reviews. Word Challenge and Sentence Practice games keep you engaged.

Speech & Audio

Listening & Speaking

AI text-to-speech for listening exercises, speech recognition for pronunciation. Fluency scored on accuracy and intonation in real time.

Learning Science

Error-Driven Spaced Repetition

Every mistake (in exercises, lessons, writing, your placement test, or chat) automatically becomes an SM-2 review card in your Practice section. Errors are categorized by type and severity, then resurfaced at optimal intervals and retired once you've mastered them. Your weaknesses become strengths.

Writing Feedback

AI Writing Analysis

Submit essays and get instant AI feedback: grammar, spelling, and vocabulary errors categorized by type with detailed explanations.

Teacher Q&A

Teacher Q&A Chat

A structured Q&A mode where the AI teacher poses grammar and vocabulary questions, scores your answers, awards XP, and gives detailed explanations for every response.

FAQ

Common questions

Yes. Glossemera is currently focused on English as the target learning language, covering all CEFR levels from A1 (complete beginner) to C2 (mastery). The platform is especially well-suited for Sri Lankan learners, with built-in Sinhala and Tamil guide support.

The Guide is a floating AI chat panel that appears on every page of the platform. You can ask it questions about what you are studying and it will reply in Sinhala (සිංහල) or Tamil (தமிழ்), whichever you choose. It understands your context (which lesson, exercise, or page you are on) and suggests relevant topics to explore.

The assessment generates fresh AI questions across 6 skill areas (grammar, vocabulary, reading, writing, listening, speaking). It adapts in real time: if you get questions right, difficulty increases; if you struggle, it eases off. Early stopping detects your level once confidence is high. You can also skip the assessment and start at A1 if you prefer.

Luna is your full conversational AI tutor who holds open-ended conversations, remembers your full chat history across sessions, embeds mini-exercises mid-chat, and adapts to your learning focus. Teacher Chat is a structured Q&A mode where the AI poses grammar or vocabulary questions, scores your answers, and gives detailed explanations with XP rewards. Both are great: Luna for free practice, Teacher Chat for focused drilling.

The Live Voice Teacher lets you have a real-time spoken conversation with Iresha, your AI teacher. You simply talk, and she replies out loud in natural speech the moment you pause — no typing, no buttons. Every reply is matched to your CEFR level, making it ideal for pronunciation and fluency practice. She can launch on-screen quizzes mid-conversation that award XP, and she remembers the session so you can pick up where you left off. It is available as a premium voice add-on.

Glossemera generates complete podcast episodes on demand with full dialogue between a host and guest, a readable transcript, and an audio player, all matched to your chosen genre and CEFR level. You can share your favorite podcasts to the Community Library for other learners to discover.

Yes, the web app is fully responsive and works on any modern mobile browser. The browser extension (for vocabulary lookup while browsing) works on Chrome, Edge, and Firefox on desktop.

After your 5-day free trial (or 100 AI requests, whichever comes first), AI-powered features like lesson generation, exercises, and chat require a Pro subscription (LKR 990/month). Non-AI features like reviewing saved vocabulary, viewing lesson history, and the learning journey remain accessible.
