Problem
Traditional to-do apps and note-taking tools require navigating complex menus, setting up multiple integrations, and following rigid formatting, which creates friction and discourages consistent use. Many productivity tools also fail to offer reliable offline access and true data privacy, forcing users to choose between convenience and control over their personal information.
Solution
Tetrify provides a simple, chat-based interface where users type natural-language instructions to create reminders, capture notes, and organize tasks. The app works offline by default, storing data locally on the device, and offers optional end-to-end encrypted sync across devices using the open Matrix protocol. Users can create "Spaces" for different areas of life, set up recurring routines that fire automatically, and view messages as timelines or traditional to-do lists. Tetrify supports Apple Calendar integration, Markdown and CSV export, and mood tracking, all without requiring an internet connection or a learning curve.
Target Audience
Primary users are individuals seeking a low-friction productivity tool for reminders, journaling, and habit tracking, including people with ADHD who benefit from simple, text-based interaction patterns. The app also appeals to privacy-conscious users who want offline capability and encrypted data syncing.
Features
- Natural-language date parsing that runs locally on-device, enabling instant reminder creation without internet or cloud LLM processing
- Recurring routines that automatically send scheduled messages to designated Spaces, such as daily, weekly, or custom intervals
- End-to-end encrypted sync powered by the Matrix protocol for cross-device data synchronization while maintaining user privacy
- Summary Views that transform chat messages into todo lists sorted by due date or grouped by priority
- Apple Calendar integration for scheduling events directly from the app

- Offline-first architecture where data never leaves the device by default
