The problem

AI is powerful. But it doesn't know you.

01

Every AI starts from zero

ChatGPT, Claude, Gemini — none of them remember who you are. You re-explain yourself every single time.

02

Knowledge is scattered everywhere

Bookmarks here, notes there, highlights in 5 tools. Nothing connects. Your second brain has amnesia.

03

Generic answers waste your time

AI doesn't know what you already understand. You get beginner explanations when you needed the deep dive.

How it works

Three steps. Zero manual work.

01Capture

One-click save from any page

Select text, right-click, done. The Chrome extension captures highlights, notes, pins, and bookmarks without interrupting your flow. No forms, no friction.

AI builds the graph for you

Every save is embedded and linked automatically. No manual tagging, no folder hierarchies. The knowledge graph grows organically — related ideas find each other.

What did I save about chunking strategies?

Based on 3 sources: You saved a comparison of fixed-size vs. semantic chunking [1], noted that overlap of 10-20% improves retrieval [2], and pinned the RecursiveCharacterTextSplitter docs [3].
