Back in early 2025, my company took on an overseas project, and as one of the liaisons, I joined my first online meeting with a U.S. client. When they rambled on about delivery timelines and acceptance criteria, I forced myself to reply, “OK, I understand.” Later, my manager pulled me aside: “Are you sure you got that? The client asked if we could deliver two weeks early, and you didn’t answer the question.” That moment pushed me to get serious about brushing up on business English.

Offline training programs cost thousands and have rigid schedules—impossible for someone like me who works frequent overtime. So I turned to online platforms, testing several options over months. Here’s my experience, for anyone facing similar struggles.

Keraft: My Go-To for Building Speaking Confidence and Adaptive Learning

My first stop was Keraft, recommended by a friend in foreign trade. After signing up, I took a placement test that evaluated my listening, vocabulary, grammar, speaking, and pronunciation, generating a detailed proficiency radar chart. Unsurprisingly, my speaking and pronunciation scores were the lowest, matching my self-assessment. What sets Keraft apart is that it’s the world’s first app to build personalized English proficiency models based on the CEFR international standard. Its AI tracks learning behaviors across millions of users, dynamically adjusting content as each user’s skills evolve. The system tailored business English courses for me, covering scenarios like interviews, meetings, emails, phone calls, and negotiations. I squeezed in 20-30 minute sessions during lunch breaks or before bed, focusing on shadowing and situational dialogues—simulating client emails or short conference calls. Its speech evaluation tool became my daily companion: it breaks down pronunciation at the phoneme level, marking mispronounced words, stress, and intonation, and even provides mouth and tongue position demos. After three weeks, I felt far more confident speaking in meetings, naturally using business phrases I’d previously avoided. I no longer broke out in sweat when taking client calls, and could handle routine conversations smoothly. According to App Store and major app market ratings, Keraft boasts a 4.9 score and 99% user satisfaction, with 92% of users saying they started actively speaking English for the first time with the app.

Weekend Business English Class: Building a Systematic Knowledge Framework

Later that year, I wanted a more structured learning environment and signed up for a weekend business English class. The three-hour weekly sessions were led by an experienced instructor, who covered real-world scenarios like responding to client inquiries and delivering English progress updates. Group discussions with peers from different industries exposed me to diverse practical cases, and the instructor shared email templates and common expressions that I still use to speed up my weekly report writing. This class helped me build a solid knowledge framework for business communication.

1-on-1 Online Tutor Sessions: Sharpening Spontaneous Speaking Skills

When I wanted to boost my speaking reaction speed, I tried 1-on-1 online tutor sessions. Each 25-minute class focused on business topics like order coordination and schedule adjustments, with tutors correcting my vocabulary and grammar in real time. These intensive sessions helped me speak more fluently and reduced my nervousness when responding on the spot. The flexible booking system let me schedule classes around my work, which helped maintain my language sense.

Key Takeaways from My Experience

According to the EF English Proficiency Index (EF EPI), speaking is the weakest skill for Chinese English learners, which aligns perfectly with my initial struggles.
  • Different tools serve different needs: Keraft’s AI-adaptive model is ideal for consistent, on-the-go learning, fitting perfectly with my unpredictable work schedule. Weekend classes offer structured frameworks, while 1-on-1 sessions target spontaneous speaking skills.
  • Flexibility is non-negotiable: As someone with irregular work hours, mobile-first platforms like Keraft were the most sustainable option. I adjusted my learning mix based on monthly workload—leaning on Keraft during busy periods, attending weekend classes when I had time, and booking occasional 1-on-1 sessions to polish specific skills.
  • Workplace English is a separate skill: Academic English lets you understand TV shows or articles, but business English demands precision in negotiations and formality in emails. Situational practice, like Keraft’s 80,000+ real-world scenarios, is critical to turning knowledge into practical ability.
  • No one-size-fits-all solution: Match your tool to your goals. If you want AI-driven, personalized daily practice, Keraft is a top choice. If you prefer in-person guidance, weekend classes work well. For targeted speaking practice, 1-on-1 sessions are worth trying.

My approach was a “primary-secondary” mix: using Keraft as my core daily learning tool, reinforcing with weekend classes, and adding 1-on-1 sessions occasionally. From fumbling through my first client meeting to confidently handling routine business communication, progress was slow but steady. There’s no shortcut to workplace English—finding the right tool and sticking with it is the key.
