Our Story
Your learning tools belong together.
An integrated learning environment for academic papers and technical documents — AI chat, notes, file storage, and OCR. Synced across web and desktop.
Mission
Every day, millions of students and professionals sit down to study — and waste half their time fighting their tools.
They open a PDF in one app, take notes in another, ask an AI in a third, and manage bookmarks in a fourth. Before they know it, context-switching has eaten the morning. The work hasn't even started.
We believe there is a better way.

The Problem
Three quiet failures in how we study today.
01
Fragmented Workflow
Too many apps, too little learning
Five or more apps just to study a single topic — PDF reader, note-taking, AI chatbot, bookmark manager, flashcards. Each in its own window. Your attention is split before you even begin.
02
Context-Switching
The hidden cost of switching tabs
Every app switch takes minutes to fully recover from. Research shows context-switching can consume up to 40% of productive time — hours of lost learning every week.
03
Device Problem
Your study shouldn't break when you move
Most tools lock highlights, notes, and progress to a single machine. Start on a laptop, continue on a tablet, review on a phone — that seamless experience barely exists.
The Shift
From scattered windows to one focused workspace.
Beforefive apps, no flow

The Solution
One place for everything you need to learn.
All tools, one window
Read, highlight, annotate, and chat with AI without ever leaving your document. Everything you need lives in a single, focused workspace.
Every device, same experience
Start on your laptop, continue on your tablet, review on your phone. Your highlights, notes, and progress follow you everywhere.
Your data, your control
Privacy-first by design. Bring your own API keys for zero-cost AI, or use our managed service. Your documents never leave your device unless you choose.
