个人 AI 的难点不在给模型更多上下文,而在判断哪些上下文该真正改变答案。Rohan Paul 指出,记忆排序不能只靠相似度,还需考虑时效性、当前任务,以及新记忆是否与旧记忆矛盾,有时检索到某条记忆也应决定不让它影响回答。他认为这正是 TodayAI 做个人 AI 的思路。

Say an AI remembers that you prefer short emails.
Useful when you ask it to draft a reply.

Now say it also remembers that you were annoyed with the recipient three months ago.

Should that affect the draft too?

This is where, the hard part isn’t giving an AI more context, but knowing which context should actually change the answer.

A personal AI needs some way to rank context by more than similarity. Recency matters. The current task matters. Whether a newer memory contradicts an older one matters. And sometimes the correct decision is to retrieve something and still decide that it should not influence the answer.

That’s one of the things I find interesting about @TodayAIofficial 's approach to personal AI.

An AI can complete a task perfectly and still spend your time on the wrong thing. Imagine an assistant preparing notes for tomorrow’s meeting. A message arrives that changes the deadline, and suddenly another project needs your attention first. The notes may be excellent. The assistant still needs to recognize that your priorities have changed. As AI takes on more work, these decisions become increasingly important. Which task should come first? When is an interruption justified? When should the system ask you? That’s the question behind @TodayAIofficial’s approach to personal AI: how can an agent learn what matters to a particular person and use that context throughout the day? Memory is part of the answer. Remembering a deadline helps. Connecting it to a promise you made last week, noticing that the plan has changed, and bringing it up while you can still act takes more. It also requires a way to correct the system. People change their minds. A preference from three months ago may no longer apply. An assistant should make its assumptions visible and let you update them. I think this is a useful direction for personal AI. There’s considerable value in software that can connect scattered information and help you decide where to focus. The test will be how well it handles an ordinary, messy day: catching the commitment you might miss, explaining why it needs attention, and leaving the decision with you.
