English for expats — not for tourists
Generic English apps teach you how to ask where the bathroom is. OpiFluent teaches you how to negotiate a lease, write a professional email, handle a job interview, or join a conversation at a work event. Real AI conversations, not multiple choice. Speak with confidence in the situations that matter when you live abroad.
What You Can Learn with OpiFluent
Spoken English
Practice real conversations with an AI that speaks naturally and corrects your pronunciation. Build fluency through daily dialogue — not drills.
Pronunciation
Master the sounds that trip up French, Russian, and other speakers: the 'th' sounds, short vs long vowels, word stress, and connected speech patterns.
Business English
Emails, meetings, presentations, and negotiations. Learn the professional register you need to succeed in an English-speaking workplace.
Phrasal Verbs & Idioms
The gap between textbook English and real English. Master the most common phrasal verbs (bring up, carry on, give in) and idioms natives use every day.
Listening Practice
Train your ear across accents and speeds. Understand spoken English in real contexts — not the slow, artificial speech of traditional courses.
Cambridge Exam Prep
Prepare for B2 First (FCE), C1 Advanced (CAE), and IELTS — reading, writing, listening, and speaking components — all in one place.

Frequently Asked Questions
Can AI really help with English pronunciation?
Yes. OpiFluent uses Gemini's speech synthesis and recognition to give you real pronunciation feedback. You hear native-speed English, speak back, and the AI corrects your errors in context — unlike static pronunciation drills that do not adapt to what you say.
What is the best app for English conversation practice?
Most English apps focus on grammar exercises and vocabulary lists. OpiFluent is built around AI conversations — you engage in real dialogues covering work, social life, and daily situations, and the tutor responds naturally and adapts to your level. It is the closest thing to talking with a patient, always-available native speaker.
Is OpiFluent better than Duolingo for English?
Duolingo is effective for building basic vocabulary habits, but it relies on multiple-choice exercises and does not offer real conversation practice. OpiFluent gives you open-ended AI dialogues that train your actual speaking and listening skills — the skills that matter when you live in an English-speaking environment.
Is OpiFluent free?
Yes. The free plan includes 10 AI conversations per day, vocabulary practice, quizzes, and pronunciation exercises. No credit card required. Upgrade to Pro for unlimited conversations, voice chat mode, and full Cambridge exam preparation materials.
How is OpiFluent different from Cambly or a human tutor?
Human tutors are excellent but cost $15-50 per hour and require scheduling. OpiFluent gives you AI conversation practice available 24/7 at a fraction of the price. It is ideal for daily practice between tutor sessions, or as a standalone tool for expats who want consistent speaking practice without the scheduling overhead.

English occupies a singular position in the history of languages: it is a Germanic language at its core (grammar, basic vocabulary, word order) but its lexicon is roughly 60% Romance (Latin and French) and 40% Germanic. The Norman Conquest of 1066 flooded English with French administrative and cultural vocabulary — 'beef' (French boeuf) exists alongside 'cow' (Germanic), 'purchase' alongside 'buy', 'liberty' alongside 'freedom'. This dual vocabulary makes English simultaneously familiar to French and Spanish speakers at the word level and mystifying at the grammar level. Phrasal verbs are the notorious trap: 'give up', 'give in', 'give out', 'give away', 'give back' and 'give over' are all different actions that cannot be decoded from their parts. Irregular verbs (go/went, buy/bought, bring/brought) resist the memory tricks that work in Spanish or German. English has no gender, no case endings and mostly no formal/informal distinction — which lowers the floor but raises the ceiling for nuanced expression. On the exam side, IELTS (for immigration and university) and Cambridge certificates (B2 First, C1 Advanced, C2 Proficiency) are the gold standard. Both require all four skills: reading, writing, listening and speaking.
Frequently asked questions about learning English
Which variant of English does OpiFluent teach — British or American?+
OpiFluent's AI tutor is fluent in both. The vocabulary and example sentences default to internationally neutral English (the kind used in BBC World Service or Associated Press), which is understood in both the UK and the US. On request, the AI will switch to American vocabulary (elevator vs. lift, gotten vs. got) or British spelling conventions. The speech recognition accepts both accents, and the TTS audio is produced in a clear neutral accent. For exam preparation, specify your target — IELTS uses British-leaning conventions while TOEFL leans American.
IELTS vs Cambridge — which certification should I choose?+
Choose based on your goal. IELTS (Academic or General Training) is mandatory for immigration to Australia, Canada, the UK and New Zealand and is accepted by most universities worldwide. Scores expire in two years. Cambridge certificates (B2 First, C1 Advanced, C2 Proficiency) never expire and carry prestige with European employers and universities. The C1 Advanced is particularly valued for UK professional registration (medical, legal). If you need a one-time immigration score, go IELTS. If you want a permanent credential for your CV, Cambridge is better. Both test four skills: reading, writing, listening and speaking.
How does OpiFluent help with phrasal verbs — the biggest pain point?+
Phrasal verbs are notoriously difficult because their meaning is often unrelated to the individual words (to give up, give in, give out, give away all mean different things). OpiFluent tackles them in three ways: first, every phrasal verb appears in a full sentence with context so the meaning is inferred naturally. Second, the vocabulary sessions group related phrasal verbs (all give-X verbs, all take-X verbs) to reveal patterns. Third, you can ask the AI mid-conversation to explain any phrasal verb you encountered, get three example sentences, and hear the audio pronunciation. The spaced repetition system then resurfaces that verb at optimal intervals.
Is English still the number-one language for business globally in 2025?+
Yes — by a wide margin. English is the working language of the EU institutions (despite Brexit), ASEAN, the UN, ICAO (aviation), IMO (maritime) and virtually every major multinational corporation. Mandarin is growing but is used almost exclusively in China-related contexts. French, Spanish and Arabic are official UN languages but not universal business lingua francas. For software development, English is essentially mandatory — documentation, Stack Overflow, GitHub and the major AI tools all operate primarily in English. Proficiency in English expands your employable universe more than any other single language skill.
How long does it take to pass IELTS 6.5 from a B1 starting point?+
IELTS 6.5 corresponds roughly to B2 on the CEFR scale. If you are a solid B1 speaker (can hold conversations, understand most everyday input), reaching 6.5 typically takes 6 to 9 months of deliberate practice: 20–30 minutes daily with OpiFluent plus 2–3 dedicated IELTS timed practice sessions per week using official Cambridge IELTS practice test books. The writing sub-score is usually the hardest to raise — it requires learning task-specific essay structures (Task 1 data description, Task 2 discursive essay) that are quite different from everyday communication. Academic reading speed is the second bottleneck.
Why is English pronunciation so irregular compared to Spanish or German?+
English absorbed massive vocabulary from Old Norse, Norman French and Latin at different historical periods, each bringing their own pronunciation rules — then the Great Vowel Shift (1400–1700) dramatically changed how vowels were spoken while spelling was already being fixed in manuscripts. The result: 'through', 'though', 'thought', 'tough', 'trough' and 'cough' all end in '-ough' but none rhyme. Spanish spelling is phonemic (you read what you write) because it was standardised by the Real Academia after print was invented. English spelling predates print and was never unified. OpiFluent plays audio for every vocabulary item so you hear correct pronunciation alongside the written form.
Do articles 'the' and 'a' really cause so many problems for Slavic speakers?+
Yes — this is one of the most persistent interference points for Russian, Polish, Ukrainian and Czech speakers. Slavic languages have no articles at all; definiteness is expressed through word order, context and inflection. English uses 'the' (specific, previously mentioned or unique: 'the sun') and 'a/an' (new, non-specific: 'a dog barked') — but the rules have dozens of exceptions (no article before abstractions: 'life is short'; no article before country names: 'in France' but 'in the USA'). OpiFluent's grammar chains explicitly target article use with corrective feedback when you make mistakes in free-chat mode.
Where English is spoken
English is an official or co-official language in approximately 67 countries and 27 non-sovereign entities — more than any other language. Primary English-speaking countries by population include: the United States (~335M), the United Kingdom (~68M), Canada (~38M), Australia (~26M), New Zealand (~5M) and Ireland (~5M). As a second language, English is spoken by an additional 1.1 billion people across India, Nigeria, Pakistan, the Philippines, Kenya, South Africa and most of Europe. In the European Union, 38% of citizens speak English as a foreign language — by far the highest of any foreign language. English is the official language of aviation (ICAO), maritime navigation (SOLAS), the United Nations General Assembly, NATO, the World Bank and virtually every international scientific journal.
Free resources to complement OpiFluent
These are verified, freely accessible resources that work well alongside OpiFluent's conversational AI approach: • BBC Learning English (bbc.co.uk/learningenglish) — the most comprehensive free English learning resource online.

Excellent for listening comprehension from A2 upward; articles and transcripts available. • Cambridge English free practice (cambridgeenglish.org/learning-english) — official sample papers for B2 First, C1 Advanced and C2 Proficiency exams. Free access to past papers. • TED-Ed (ed.ted.com) — short animated lessons with transcripts and subtitles in 40+ languages. Excellent B2+ content on diverse academic topics. • LearnEnglish British Council (learnenglish.britishcouncil.org) — grammar reference, listening practice, writing samples. Particularly strong grammar explanations from beginner to C1.
OpiFluent vs other English learning platforms
English is the most competitive language learning market globally. EF English Live offers live human tutors and structured curriculum, but costs €80–150/month — significantly more expensive than OpiFluent Pro. Cambridge Online offers official preparation courses, but these are exam-specific and expensive (£200+ for a course). Italki connects you with human tutors at $8–30 per 50-minute session — effective but requires scheduling and lacks AI-driven consistency. Duolingo English is free and widely used but its gamification rewards streaks over speaking fluency, and the conversational AI component is limited. OpiFluent's differentiator is a real-time generative AI tutor available 24/7 at a fraction of human-tutor cost: ask about any grammar point mid-conversation, practise spoken English with immediate phonetic feedback, and prepare for IELTS exam sections — all from the same interface.
Realistic timeline to English proficiency
For French or Russian speakers starting at zero, these milestones are achievable at 20 minutes per day with OpiFluent: • A2 (DELF-equivalent basics): 3–5 months. Survive simple interactions, read basic texts, understand slow speech. • B1 (conversational independence): 6–10 months. Follow podcasts and TV at moderate speed, write emails, handle workplace small talk. • B2 (IELTS 6.0–6.5 zone): 14–20 months from zero, or 6–9 months from a solid B1. Academic and professional readiness. • C1 (C1 Advanced zone): 24–36 months from zero, ~12–18 months from B2. Comfortable with complex texts, idiomatic speech. These timelines assume deliberate practice. Passive immersion (watching English TV without active attention) adds time without proportional benefit.
