Open Beta — Join the Waitlist
Every time you build with Claude Code, Vibe Knowledge silently converts what happened into plain-language flashcards. No extra effort. No new apps to open.
Free tier available. No credit card required.
How it works
01
Use Claude Code the way you always do. Vibe Knowledge hooks into every Edit, Write, and Bash call automatically — nothing to configure per-project.
02
After each session, a background process asks Claude Haiku: "what concept did we just touch, in plain English?" A flashcard is born. Your session never slows down.
03
Browse by project, search your glossary, trace the concept map, or run the spaced-repetition quiz. Explain it in your own words. Close a deal.
What a card looks like
Each card captures the term, why you used it, and a real-world analogy — automatically extracted from what you actually built.
After a week of vibe-coding, you have 100+ cards, all grounded in your own projects.
What's included
Installed once. Works across every project. The capture hook runs in milliseconds and never calls an AI — zero latency, zero cost at capture time.
API keys, tokens, .env files — automatically redacted before anything is stored or sent to AI. Patterns like sk-..., ghp_..., Bearer ... are masked at capture time.
The viewer includes a forgetting-curve quiz. Grade yourself (forgot / hazy / got it). The algorithm schedules your next review automatically.
A force-directed graph of your top 40 terms. Spot clusters. Identify gaps. Watch your understanding grow over time.
Add as an MCP server. Ask "what have I learned about webhooks?" directly inside sessions. Your cards become a searchable second brain.
Your cards everywhere. Sign in, sync across machines, review on your phone. Each account gets its own private knowledge base.
Today, all data lives in ~/.claude/vibe-knowledge/data/. Nothing is transmitted anywhere.
Cloud sync (coming with the SaaS tier) will be opt-in and encrypted in transit.
