A simple AI for knowledge.Most AI does it for you. U7A helps you actually know it.
Not sure what to ask? Browse over 400 topics, updated daily, and press Go! for a short, sharp read on something you didn’t know to look for.
Chat is for whatever you’re curious about. Ask in your own words and it builds on what you say. Ask it simpler, go deeper, push back.
Write it down in a clean, text-only editor. It’s saved to Documents in the cloud, on the web and on your phone.
U7A never acts for you or works in the background. It’s one chat, a library of topics and a plain editor, so everything on screen is about understanding, not managing tools.
Three things that happen to almost everyone, and what U7A does about each.
Hands you a bite-sized topic you didn’t know to ask for, fresh every day. Press Go! and there’s always a next one.
Curiosity starts when you notice a gap in what you know, and a good prompt creates that gap for you. And curious people remember more: in lab tests, they recalled more a day later, even things unrelated to what sparked their curiosity. Loewenstein, 1994 · Neuron, 2014
Explains in plain words, then follows you. Say “simpler”, “go deeper” or “I don’t buy that” and it adjusts, at any hour.
A tutor that adapts to you beats a lecture that doesn’t. In a Harvard trial, students with a purpose-built AI tutor learned more, in less time, than in class. Harvard trial, 2025
Write what you learned in your own words in Smart Editor and it’s saved to Documents on the web and your phone, ready to come back to.
Forgetting is fastest soon after you learn something, then slows. Pulling an idea back out of your head, instead of re-reading it, helps it last: in a classic study, people who practised recalling remembered more a week later than people who re-read. Forgetting curve, 2015 · Roediger and Karpicke, 2006
The result: you finish knowing something you didn’t, and you still have it next week.
Agents do things for you. Search hands you links. U7A is built for the moment you just want to understand something, and keep it.
Discover hands you something worth knowing at the press of Go!, so a blank page never stops you.
Chat explains in your own words. Ask it simpler, go deeper or push back until it clicks.
Write it down in Smart Editor and it’s saved to Documents, ready next week, on the web and your phone.
