About memex
Memex is an open-source, local-first AI journal app designed for iOS and Android. Unlike traditional journaling apps, it focuses on capturing life fragments such as text, photos, and voice, which are then organized by AI into structured timeline cards and insights.
The app operates on a local-first principle, meaning all data remains on the user's device without reliance on cloud storage or external servers. Users can integrate their preferred large language model (LLM) providers, including OpenAI, Claude, Gemini, and others, ensuring privacy and direct control over their data.
