Summary

Memex is a free, open-source journal app for Android and iOS that turns text, photos, and voice into timeline cards and insights. It is aimed at people who capture everyday details in fragments, such as observations, tasks, and voice memos. On-device OCR, image labeling, and photo EXIF extraction help process captured material. AI agents sort records into categories such as tasks, events, people, places, and transactions; the app surfaces patterns through charts, timelines, quotes, and narrative summaries. Records are kept as Markdown files and in a local SQLite database, with export, backup, and restore options. Backups can go to iCloud Drive, a custom folder, or app storage. Users bring their own model provider, with options including OpenAI, Claude, Gemini, Ollama, and others. AI features require a configured model service, which may incur provider charges. When a third-party model is configured, text, photo metadata, OCR text, and card content may be sent directly to that provider for processing. Memex is published under GPL-3.0.

Who it is for

Memex suits people who want to turn scattered notes, photos, and voice recordings into an organized personal journal. It may appeal to users who want local storage and a choice of AI model provider.

What is good

What to know first

Verdict
