How AI tools can help level up your child’s PSLE English oral performance
13/05/2026
SINGAPORE – A soothing voice with the calm cadence of an expert narrator to benchmark against, a curated bank of annotated passages for reading practice, and comprehensive scorecards with personalised feedback to help students improve.
Built by Mr Moses Soh, 33, deputy chief executive and head of academic innovation at Mind Stretcher, cher.ai allows students to practise independently and receive detailed feedback as part of the education group’s suite of PSLE preparation tools.
Mr Soh, who studied artificial intelligence at Stanford University, believes technology opens up new possibilities and helps level the playing field.
He last worked at Open Government Products, where he led the development of Pair, the Government’s secure AI platform for public servants.
Levelling the playing field
Mr Soh says: “Even in the best schools, students might get only two to four oral practice sessions a year and the feedback might not be very detailed. Private one-on-one tutoring for oral practice is expensive. Technology offers solutions that were not possible in my generation.”
Mr Soh, who built cher.ai over two months in 2025 at an estimated cost of $100,000, says he did so to scale the kind of feedback he wishes he could give every student.
In 2025, the system handled and assessed more than 3,000 practice sessions, dispensing feedback that would have taken teachers more than 1,500 hours to deliver, he adds. All Mind Stretcher students currently have free access to the platform.
Cher.ai costs $25 a month for its starter preview plan, which gives users early access to the platform as tools continue to be developed and refined, says Mr Soh.
At least three other AI-powered platforms for PSLE English oral practice exist online today.
