Today.ai: Qi Junyuan's personal agent bets on long-term memory and proactivity
赛博禅心 · wechat · 2026-09-22
A visit to the team behind Today.ai, Qi Junyuan's new Personal Agent (domain bought in 2014). Key takeaways: memory systems must be scenario-specific, embedding domain understanding into the product; the north-star metric is problems the agent proactively solves, not user queries; the PM replaced her English tutor with a fully personalized AI course; and co-founder Gao Ce argues memory + proactivity remain the durable bet as model capabilities shift.
