Memex
Memex is a free, open-source journal for Android and iOS that turns text, photos, and voice recordings into organized timeline cards and insights. On-device OCR, image labeling, and photo EXIF extraction process captured material, while AI agents sort records into categories such as tasks, events, metrics, people, places, galleries, articles, and transactions. The app can show patterns as charts, timelines, quotes, and narrative summaries. Records are kept in Markdown files and a local SQLite database, with export and backup or restore options. Backups can go to iCloud Drive, a custom folder, or app storage. Users configure their own model provider, with options including OpenAI, Claude, Gemini, AWS Bedrock, OpenRouter, and Ollama. AI features require that service and may incur provider charges; text, photo metadata, OCR text, and card content may be sent to the selected provider for processing. The maker says journal data is not uploaded to a server. Memex also supports biometric app lock and custom agents with triggers, prompts, JavaScript, and inter-agent workflows.
