One Person. One Weird Idea.
A Lot of Audio Courses.
obyo is a side project by Braviata, which is a fancy way of saying one guy named Izzy Hyman who builds things in his spare time.
The Problem
Audiobooks and podcasts make it easy to learn while you walk, drive, or do dishes — but the catalog is whatever was lucrative enough to record years ago. The very specific thing you actually want to learn? Usually missing.
The Fix
obyo generates narrated, chaptered audio courses on demand — with real research, cited sources, and a full written transcript. Press play during your commute, and actually finish learning something this week.
How it works (the short version)
You give us a URL
YouTube video, article, docs page — whatever sparked your curiosity.
AI goes deep
It researches the broader topic, finds related sources, and writes a full script with cited claims and clean chapter breaks.
Press play anywhere
Listen on a walk, in the car, or doing chores. The written transcript is right there if you want to skim later. Every course is free, forever.
Why it's free to listen
Every course on obyo is free to listen to with a free account. Funding a course costs a small fee to cover the AI generation and narration costs, but once it exists, it's here for everyone. The person who funds a course is a patron of knowledge, not a gatekeeper to it.
The one-person thing
Braviata is not a venture-backed startup with a ping pong table and a mission statement written by committee. It's one person who thinks learning should be more accessible, more memorable, and a lot less boring.
The upside
Decisions happen fast and there are no meetings.
The downside
If something breaks at 2am, there's only one person to blame.
