## What is PaperBrain?

PaperBrain turns your handwritten notebooks into a searchable, AI-powered knowledge base—without changing how you take notes.

Snap a photo of any notebook page, upload a scan, or drag and drop an image. PaperBrain reads real handwriting, organizes your notes, and lets you ask natural-language questions about everything you've ever written. Every answer links back to the original page, so you can verify the source instantly.

HOW IT WORKS

1. Capture your notes. Photograph notebook pages, scan documents, or upload existing images.
2. AI reads your handwriting. PaperBrain recognizes cursive, messy handwriting, lists, headings, and even crossed-out text while preserving your page structure.
3. Ask anything. Search your library or chat with your notebooks. Every response includes citations to the exact page it came from.

FEATURES

• Search every handwritten page with full-text search.
• AI helps you search, synthesize, manage, and continually learn from everything in your notebooks.
• Tags are generated automatically and improve over time as you refine them.
• Create collections manually or let AI organize and update them for you.
• Time-aware search for finding notes from specific dates, projects, or events.
• Share individual pages with the original image and extracted text side by side.
• Export your notes as Markdown whenever you want.
• Original pages are always stored alongside extracted text, so the source is never lost.

BUILT FOR PEOPLE WHO THINK ON PAPER

• Students who need searchable lecture notes before exams.
• Researchers managing field notebooks and study journals.
• Professionals keeping meeting notes, sketches, and project journals organized.
• Anyone with shelves full of notebooks they wish they could search.

YOUR NOTES STAY YOURS

Your notebook pages are encrypted at rest and remain your data. PaperBrain is built to help you remember, connect ideas, and get more value from your notes—not to train public AI models.
