About Memex
Memex is an open-source, local-first AI journal app designed to help people capture real life in raw form and let AI organize it without taking ownership of the data.
What we are building
Memex is built for people who record in fragments: short notes, photos, voice memos, observations, tasks, and loose thoughts. Instead of forcing you to structure everything by hand, Memex uses AI to turn those fragments into timeline cards, extract knowledge, and surface patterns across your records.
We think a journal should become more useful over time, not more buried. The goal is not only to store your life, but to help you understand it.
Team and contributors
Memex is developed by a small team and open-source contributors. Haibo Wu initiated the product and remains one of its core contributors, focusing on product direction, AI workflows, and the thinking behind local-first personal memory.
Why local-first matters
Personal records are unusually sensitive. They often contain private thoughts, relationships, health context, and unfinished ideas. That is why Memex is designed around local-first storage, portable files, and user-controlled model access.
- Your records stay on your device as Markdown files and a local SQLite database.
- You choose the LLM provider instead of being locked into one hosted model.
- The code is open source, so the behavior is inspectable and auditable.
