Four Computers Science undergraduates from NUS Computing were featured in The Straits Times for AHMA, an AI-powered app designed to help caregivers in Singapore find support services that match their needs.
Aishwarya Goyal, Hazel Low, Abhishek Paranjape and Andrew Soon began the project at a hackathon in 2025, drawing on their own experience caring for grandparents and supporting friends through mental health difficulties. Speaking to ST, Abhishek described the gap the team chose to work on as resource navigation: Singapore's social service agencies and government schemes offer a great deal to caregivers, but many struggle to work out which options apply to them.
AHMA uses a voice interface as its primary mode of interaction, a choice the team made with older caregivers in mind. A user can speak to the app about their situation and receive encouragement along with pointers to relevant community organisations. It currently supports English, Malay and Mandarin, and the team is working on adding dialects. The text-to-speech model was trained on Aishwarya's voice so that it sounds familiar to Singaporean users.
The students have been gathering feedback from caregivers, including at a recent session run by Mindfull Community, a non-profit that supports caregivers and families of people with mental health conditions. Hazel told ST that co-creating with caregivers is central to how the team works. Mindfull's deputy head of partnerships, Samantha Foo, said the sessions were valuable for both sides, and that the organisation intends to review the app once a working version is ready.
The team plans to launch a working product in the coming months.
Provost's Chair Professor Hahn Jungpil from the Department of Information Systems and Analytics joined CNA938 The Big Question, to discuss two Singapore-made AI-generated films that have reignited debate over AI's role in creative work – and where the line sits between AI as a tool and AI as a crutch.
Prof Hahn warned that critical thinking is the skill most at risk of quietly fading: "It's so accessible, and it provides relatively good output right from the start. You have to dig deeper, challenge it, even fight with it, to get really good content out of it. A lot of people, especially students, stop short of doing that and just accept what they're given. That's the real danger – we stop exercising our own reasoning."
He also argued that augmentation and replacement aren't opposites but a matter of time: "Augmentation only stays augmentation if you deliberately keep a hand in what you're doing, and that's a very difficult thing to do day to day." Left unchecked, he said, this deskilling happens quietly – "AI attacks that aspect of skills development most critically, and invisibly. We don't realise it until the skill is gone." – with judgement itself eroding the less it's exercised.
On NUS' move to make AI coursework compulsory for all undergraduates, he said assessment needs to evolve in step, favouring oral reasoning tests over take-home essays that AI can easily produce – so students are evaluated on how they think, not just what they output.

NUS Business Analytics Centre has received a S$1.5 million personal donation from Mr Xie Xin, President of Lark Technologies, the largest single gift in the centre's 13-year history, Lianhe Zaobao reported on 7 August.
S$1 million of the donation establishes a new scholarship for students in the Master of Science in Business Analytics (MSBA) programme, with up to two awards expected in its first year and plans to extend it further. The remaining S$500,000 sets up an AI fund at the centre to support trustworthy AI research, including work on building AI systems that are safer, more reliable and more accountable.
Associate Professor Terence Sim from the Department of Computer Science joined CNA938 #TalkBack segment on facial recognition technology in public transport, prompted by the closed trial now underway at Punggol Coast MRT Station.
Host Daniel Martin put the question to Prof Sim, whose research spans biometric authentication and facial recognition: can a system built to verify one face at a time handle a gantry at rush hour?
Prof Sim's answer centred on throughput. Similar systems already run in cities such as Beijing, Osaka and Moscow, but Singapore's population is more racially diverse than most, and that diversity exposes a known weak point. "It's been found that darker skin tones cause problems for the systems, elderly women tend to have difficulty, and of course children, because their facial structure changes rapidly," he said, adding that headgear, masks and even a fresh shave can throw off a match against someone's enrolled image.
Average daily MRT ridership hit 3.49 million trips in 2025, according to the latest LTA statistics, concentrated in evening bursts between 5pm and 7pm, a volume far beyond any office facial recognition deployment. Prof Sim outlined three ways such a system can fail: false positives, false negatives, and misidentification, where one enrolled commuter is charged for another's ride. Citing the best error rates he could find, he estimated roughly 10,500 people could be barred from the gate daily, and about 1,750 could be wrongly charged for someone else's trip.
His conclusion: lighting, crowding and privacy concerns mean facial recognition technology is unlikely to replace tapping outright.
