Open Beta — Join the Waitlist

Your coding sessions.
Turned into knowledge.

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.

You're on the list. We'll reach out when cloud sync is ready.

Free tier available. No credit card required.


How it works

01

Build as usual

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

Cards appear silently

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

Open the viewer, review, repeat

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

Plain language,
every time

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.

Webhook
ウェブフック
A way to automatically notify another system the moment something happens.
To notify our server when a Stripe payment completes — without polling.
Like a doorbell. You press it when something happens, whoever's home responds.

What's included

Auto-capture

Hooks in silently

Installed once. Works across every project. The capture hook runs in milliseconds and never calls an AI — zero latency, zero cost at capture time.

Privacy

Secrets never leave your machine

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.

SM-2 Quiz

Spaced repetition built in

The viewer includes a forgetting-curve quiz. Grade yourself (forgot / hazy / got it). The algorithm schedules your next review automatically.

Concept Map

See how ideas connect

A force-directed graph of your top 40 terms. Spot clusters. Identify gaps. Watch your understanding grow over time.

MCP Server

Query your knowledge from Claude Code

Add as an MCP server. Ask "what have I learned about webhooks?" directly inside sessions. Your cards become a searchable second brain.

Coming Soon

Cloud sync + mobile

Your cards everywhere. Sign in, sync across machines, review on your phone. Each account gets its own private knowledge base.


Your code stays
on your machine.

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.

Be first when
cloud sync ships.

The local version is free and open source. Cloud sync, mobile, and team features are coming.
