About APSE
What is Apse?
Apse is short for A Personal Search Engine. It runs on your computer, and keeps track of what you see on your screen.
Apse lets you search for anything you've seen on your computer, so you won't ever lose something again.
Who's behind APSE?
Apse is made by Ryan Fox.
Why did you build APSE?
I built a search engine because I forget things All. The. Time.
Come on Google, I've looked up this exact thing, why can't you find it for me?
On top of that, big search engines collect every scrap of your data they can get their hands on.
So I built Apse to do 3 things:
- Be a universal search interface,
- With relevant results, and
- Respect users' privacy
And that's what it does today! It's really useful to me - I made the thing, and it still surprises me how well it works. And the more you're on your computer, the more it can help you.

Who is Apse for?
I am a software developer, so I am glued to a screen all day. I also look at a lot of things online - documentation, email, chat, source code, research papers, you name it.
I originally built Apse to scratch my own itch, so if you're a software developer or data scientist it will be useful to you too.
It's also good for anyone who needs to recall old information: consultants, tech workers, project managers, researchers, students, recruiters, or anyone else who has ever cursed a search engine for being unable to find something.
Where can I find out more?
Are you using Apse for something different? Have any questions? I would love to hear from you. Send me an email here. I read them all myself, and will respond to you as soon as I can. If Apse sounds useful, you can get it now:
