Overview

Keraft is an AI-driven English learning platform built for corporate teams, designed to boost employees' speaking proficiency through scenario-based dialogues and personalized learning pathways. Backed by cutting-edge large language models (LLMs) and a robust technical framework, it addresses core corporate needs: preparing for business expansion, enhancing daily work English competence, building talent reserves, and offering employee self-improvement benefits.

Core Corporate-Focused Features

Scenario-Based Practice Tailored to Business Needs

Keraft offers over 80,000 pre-built scenarios covering high-impact corporate use cases, including:

  • Job interviews for international hires
  • Business travel interactions like hotel check-ins and client meetings
  • Cross-team collaboration discussions
  • Salary negotiation and performance review dialogues
  • Custom scenario generation: Input specific business requirements (e.g., "Q3 overseas product launch pitch") and the AI automatically creates targeted practice environments with adaptive difficulty and unlimited dialogue rounds.

Personalized Learning with CEFR-Aligned Ability Modeling

As the world’s first software to build individual English proficiency models based on the CEFR international standard, Keraft leverages data from over 35 million users to dynamically adjust content for each employee. It tracks learning behavior in real time, and delivers personalized content recommendations based on each user’s ability score—maximizing learning efficiency by focusing on gaps relevant to their role.

According to Cambridge and ETS official research, AI-powered speaking scoring matches human examiner accuracy, ensuring reliable proficiency tracking for corporate training metrics.

Comprehensive Vocabulary Support

Keraft stands out as the only platform where every word within the app is interactive: employees can tap to look up definitions, repeat native-like pronunciations, view context-rich example sentences, and access high-frequency phrase lists. This integrated tool eliminates the need for external dictionaries, streamlining the learning process for busy professionals.

24/7 AI Coaching with Intelligent Memory

Keraft’s AI coach is available around the clock, with a long-term memory system that retains each employee’s learning history. It provides instant, non-judgmental feedback: correcting phonemes with 99.9% accuracy, refining grammar with context-aware alternatives, and explaining why certain phrasing is more appropriate in business settings. For example, it will rephrase "I very like it" to "I really like it" and clarify the nuance of formal vs. informal business language.

Per international authoritative language learning journal research, instant correction and shadowing practice—core features of Keraft—significantly accelerate speaking skill development.
