What it is
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 designed for people who capture everyday details in fragments, such as notes, observations, tasks, and voice memos. On-device OCR, image labeling, and photo EXIF extraction help process entries. AI agents sort records into categories including tasks, events, metrics, people, places, galleries, articles, and transactions; the app surfaces patterns through charts, timelines, quotes, and summaries. Records are kept as interconnected Markdown files and in a local SQLite database, with export, backup, and restore options. 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. Backups can go to iCloud Drive, a custom folder, or app storage. The project is published under GPL-3.0.
For and against
For
- Free app for Android and iOS.
- On-device OCR and image labeling.
- Records stay in local Markdown files and SQLite.
- Supports backup, restore, and one-click export.
Against
- AI features require a configured model service.
- Configured providers may receive journal content.
- Provider charges may apply.
- Transcription supports five languages.
The verdict
Memex combines local journal storage with AI-based organization and insights. Its free download still requires a separately configured model service for AI features, and configured providers may receive content for processing.
Who it suits
Memex may suit people who collect short notes, photos, voice memos, observations, and tasks and want them organized into a journal. It also suits users comfortable configuring their own model provider.
