It's Been a Minute

Well.

Some of you may be old enough to remember a time when RoverAI was all about audio. We set out to build an app that could answer any of your questions and produce the answer in the form of a short podcast (yes, we know Spotify does this now. But way back in 2025 it didn't! It was a real problem!). And we did! Rover the Audio app worked great, did what it was supposed to, everything we thought we wanted.

And we were all kind of "meh." Worked fine, we didn't love it. And we had the core problem, which our early users confirmed to us, that there's already enough AI slop in the world.

It wasn't magic. We didn't get into this to not do magic.

So we talked to a lot of people, and thought a lot more, and went back to the starting point: What do we want from AI? We want this:

• A way to remember all the things we read/watch/listen to on our devices; a thing that would be essentially a database of our taste, of what we know, how we think, what we value.
• A way to point an LLM at that database so that we could easily interrogate it to help us think better.
• A way to share these thoughts/info with others.

Foundational to all this: We want to retain ownership and control. This database should live on our machines, in markdown files that are easily readable by human or AI, files that any user can change, trash, admire.

And so we built Rover, which, yes, we know it's the same name but hear us out: Rover is a daemon.

I KNOW, RIGHT? We'll dig into this idea a bit more later, but for those of you who maybe haven't been lucky enough to have read Philip Pullman's The Golden Compass, (or seen the HBO series; stay far away from the 2007 film), a daemon is a manifestation of your self, a separate entity that knows you and your tastes, remembers what you remember, a thing you can talk to and learn from. In the Pullman books everyone has a daemon, an entity with its own name that takes the form of an animal that reflects the person's personality, like....Rover. (It's also of course the name for a Unix program that runs autonomously in the background like...Rover) And, like Pullman's daemons, Rover can communicate with others--join a pod with another Rover user and you can access parts of what that user knows.

Crucially, though, this is what Rover is not: A replacement for a personal assistant. There are plenty of them out there, and they always leave me kind of cold. This captures it for me:

Technology enthusiasts severely overestimate the average person’s desire or willingness or capacity to build and use AI agents. I understand some work roles that could mandate or encourage it but that is no way a tech revolution. Agents are best for structured, clearly delineated tasks.

I've always kind of felt that having the kinds of agents that currently exists doesn't really solve a lot of problems for me. I book my own travel and enjoy doing it. I know how to cook and don't need something to order groceries for me. My kids Would Rather Die than be in a family group chat. I've used Muse, Instinct, Town, etc etc etc have abandoned them all (sorry, AI assistants!).

The goal with Rover is broader and deeper. Rover is a compiler. It does not just aggregate bookmarks; it builds a structured, typed model of how you think using Markdown files (stances, interests, references, decisions). Download Rover to your desktop, hook up any source of your choosing (photos, browser history, text messages, Bluesky posts, Obsidian files, Substack subscriptions, etc) and Rover compiles them into files that map how you think--what you know, what you value. These files are always yours--they stay on your machine, and you can keep them forever.

There are profiles of you you all over the Internet, held by all sorts of people who are not you. We want to bring this back to your control. ChatGPT remembers what you tell it in chat; Muse remembers your conversations and other things like you email, back account, etc if you connect them (but you are of course sending this all straight to Mark Zuckerberg). Today, your records are remembered in other places that are not your own, by people who make their business selling your stuff to others.

That's not Rover. Our fundamental commitment is that all your data is yours, and we will never build our business off of holding your thoughts hostage. We want to help you remember better, think better and connect to others better—while keeping your data—your daemon!—intact with you.

So what do you think? Let us know.
