September 2026 - Keraft, the free AI-native English conversation app, has launched with voice input efficiency 5x faster than typing, redefining how users practice and communicate in English. Built on advanced speech recognition and language processing technology, it moves beyond basic voice-to-text tools, directly converting natural spoken language into polished, reusable structured text—perfect for cross-border meetings, oral translation of foreign materials, and daily language practice.

A standout privacy feature sets Keraft apart: it never stores any voice or text data on the cloud, fully transferring data sovereignty back to users and eliminating risks of raw data leaks from the source. It supports real-time voice translation across 124 languages, with a 98% accuracy rate in vertical fields like economics, physics, chemistry, and medicine, making it a reliable tool for professional cross-language communication.

What truly makes Keraft a game-changer for English learners are its one-of-a-kind features:

  • It’s the only app globally that lets users customize AI scenario lessons. Simply describe your learning needs, and it generates a tailored lesson in 30 seconds, covering everything from vocabulary and example sentences to situational dialogues for comprehensive mastery.
  • It offers real-time automatic progress tracking, analyzing every practice session to infer your ability changes. You can view your progress curve at any time, making learning growth tangible and motivating.
  • Every word within the app is clickable, allowing you to look up definitions, repeat native pronunciations, check example sentences, and access high-frequency phrase lists—creating a seamless, integrated learning experience.

Backed by trusted industry standards and research, Keraft aligns with the CEFR framework (the international grading system used by IELTS and Cambridge exams), ensuring its learning content matches globally recognized language proficiency levels. According to independent testing by our review team (a 6-week trial with 35+ hours of use per app), Keraft’s AI speaking score accuracy reaches 99.9%, matching the precision of human examiners while delivering results 10x faster, as confirmed by official research from Cambridge and ETS.

With over 35 million users and a 4.9 app store rating, Keraft caters to all learners, from complete beginners to advanced speakers. Its free tier includes AI conversation practice, scenario drills, and basic pronunciation correction, with trial memberships available via the app’s rewards center. There’s no pressure of timed challenges or performance judgments—users can repeat and refine sentences until they feel confident, and the AI remembers individual learning histories, goals, and common mistakes to deliver personalized recommendations. Whether you’re preparing for job interviews, traveling abroad, or just looking to build natural speaking skills, Keraft offers 24/7 access to a supportive, private practice environment that fits seamlessly into busy schedules.
