In their own words
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.
Nuju
Nuju is an AI journal and mood tracker for quick emotional check-ins, written or spoken journaling, and reflections on patterns over time. Users can log mood and energy, write an entry, or speak when typing feels difficult; an AI reflection responds to what they wrote. Nuju also surfaces repeated moods, habits, and moments, and offers four coach styles: Gentle, Wise, Tough, and Fun. The product is a progressive web app installable on iPhone, Android, or desktop, with iOS listed as a mobile app platform. Nuju says entries are encrypted at rest and separated through end-to-end account isolation. It also says personal journal content is not used to train general-purpose AI models and personal data is not sold. Users can request access, correction, export, or deletion of their data; account deletion removes associated data within 30 days unless law requires longer retention. The Free plan includes one personal reveal, a 10-second mood check-in, and three saved entries. A 7-day trial is listed.
