One Person. One Weird Idea.
A Lot of Guides.
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
There's an overwhelming amount of great content on the internet — YouTube videos, articles, docs, tutorials — and a frustrating amount of it goes in one ear and out the other. You watch a 45-minute video, feel smart for an hour, and forget everything by Thursday.
The Fix
We built a tool that turns any source into a structured, well-researched guide with cited sources and interactive exercises. Because your brain deserves better than "I watched a video about that once."
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 builds a full guide with structured sections and citations.
You actually remember it
Study online with interactive exercises, take notes, or share with anyone. Every guide is free to access, forever.
Why it's free to learn
Every guide on obyo is free to study with a free account. Funding a guide costs a small fee to cover the AI generation costs, but once it exists, it's here for everyone. The person who funds a guide 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.
