Find terms
Pull terms from what you read, paste, discuss, and save. Keep the ones that matter. Shelve the rest.
Your private learning glossary
For the things you half-know.
Glossary.dev tracks the terms that keep appearing in articles, docs, and chats, and ensures you can actually explain them.
The problem
You collect context faster than you close gaps.
Modern learning leaves a trail: bookmarked papers, Claude conversations, copied docs, Readwise highlights, notes, and source files. Hidden inside that trail are the concepts you skim.
These concepts are familiar enough to pass over, weak enough to fail when you need to reason with them.
The philosophy
Learning needs a record.
Keep a record of what you are learning, how well you understand it, and what to test next.
Glossary.dev does the bookkeeping. It notices repeated terms, keeps their sources, tracks confidence, and gives you a tutor that asks where your explanation gets thin.
What it is
A glossary that knows where you are.

Quiz & Discuss
Explain a term, ask questions, and keep going until the gap is clear.
Tutor memory
The tutor learns what you like, what you know, and where you get stuck from your discussions.
The data
Plain markdown. Your words.
The glossary is stored as readable markdown files. The app reads and writes those files.
Your learning state stays portable. Agents, scripts, notebooks, and editors can read the same glossary.
Today, Glossary.dev is built around this markdown shape with the intent to connect to your own storage (Google Drive, iCloud). Connecting it to your own storage, editors, and agent tools is coming soon.
