Use case
Most second-brain apps store notes. Memo reads your PDFs, pages and files, extracts the entities and relationships, and answers questions across everything you've ever filed.
The idea
A second brain is only useful if you can find what’s in it. Note apps give you a place to put things; the remembering, linking and re-reading is still on you. Memo takes that work off your plate. It reads every document you file, understands what it’s about, and connects it to everything else — so your knowledge compounds instead of piling up.
Not just storage. Memo extracts the meaning from PDFs, pages and notes so everything is searchable by what it says.
Entities and relationships are extracted and linked automatically. The same person or concept across files becomes one node.
Ask across everything you’ve filed and get a cited answer — no hunting through folders.
Your documents are yours. Nothing is public unless you explicitly share it, via a revocable link.

01
Upload anything
Drop in PDFs, web pages, notes and files. The bytes go straight to secure storage — Memo never sits in the way.
02
Memo reads it
Each document is chunked, embedded and mined for entities and relationships, then woven into your existing graph.
03
Ask anything
Search by meaning or ask a question in plain language. Memo answers from your own corpus, with citations.
