EnglishQuest : Anglais Enquête
Efaktech
English Quest: Learn English by solving mysteries in London. Real police investigations, HD voiceovers, and English grammar from A1 to C1 levels.
Do you really want to learn English, and not just do exercises?
English Quest immerses you in the heart of London alongside Detective Vex and Sergeant Liza Hart. You'll conduct investigations, interrogate suspects, analyze clues, unmask the culprits... and learn English without even realizing it.
🎬 CRIME SERIES, NOT LESSONS
Each English Quest series is a complete investigation:
- The Vanishing Model: A top model disappears in 1955 London.
- Project Helix: Industrial espionage at the pinnacle of British capitalism.
- The Magdalen Letters: A stalker threatens a student at Oxford.
- The Blackout Murder: A murder in a Sussex hotel during a power outage.
New series are added regularly. Each story teaches you English vocabulary and grammar adapted to its context, from everyday language to professional registers, from formal speech to cozy mysteries.
🎙️ REAL VOICES, NOT ROBOTS
Each character speaks with their own AI-generated voice (Eleven Labs). You'll hear Vex grunt in a London alley, Liza cheer you on, and suspects lie convincingly. It's immersive, and your ear will get used to hearing authentic English.
📚 STRUCTURED ENGLISH GRAMMAR A1 → C1
More than 96 English grammar lessons organized into clear sections:
- The basics for beginners (A1-A2).
- Grammar by series to reinforce what you read (English B1).
- Advanced bonuses to progress to levels B2 and C1.
- Indirect preparation for the TOEIC, TOEFL, and Cambridge exams.
At the end of each section, a mini-exam presented by Vex or Liza. A score of 80% or higher allows you to pass the section and earn bonus XP.
🕵️ INTERROGATIONS
When a suspect lies, you present them with incriminating evidence. Vex points and shouts "LIAR!" and a manga animation appears on the screen. With English Quest, learning English becomes a game.
