Try MemX Free

Obsidian is a local-first markdown editor known for bidirectional linking and an extensive plugin ecosystem. It stores everything as plain markdown files on your device, giving you full data ownership.

MemX takes the opposite approach to knowledge management. Instead of manually writing and linking notes, you upload documents, photos, and files, and the AI understands and indexes everything automatically. You retrieve information by asking questions, not by navigating a graph of notes.

Obsidian rewards users who invest time building a structured knowledge base. MemX is for people who want to dump everything in one place and find it later without any organizational overhead.
