Common questions
What is subtxt and how does it work?
subtxt is a mobile-first iOS app that gives you relationship intelligence, not guesswork. You manually capture screenshots of your conversations, and the app extracts text via AI-powered OCR, then analyzes communication patterns to surface insights about relationship health, engagement balance, and behavioral flags. It's context, not confusion.
Is subtxt a messaging app or does it read my messages automatically?
No, subtxt is not a messaging app and does not access your messages automatically. It's not reading everything—only the screenshots you select. All data capture is user-initiated, meaning your conversations are never monitored in the background. You choose what to share.
What kind of relationships can I track with subtxt?
subtxt supports all relationship types including friends, family, work colleagues, and dating. Each contact can be categorized, and the AI analysis considers the relationship context when generating insights. Start with one person—add more as patterns emerge over time.
How does subtxt measure relationship health?
subtxt analyzes multiple dimensions including: Health Score (0-100 overall wellness), Engagement Balance (who initiates more), Emotional Temperature (warmth of communication), Responsiveness patterns, and behavioral Flags (green, yellow, red patterns). These metrics combine to give you clarity, not conclusions—the more you add, the clearer it gets.
What are green, yellow, and red flags in subtxt?
Flags represent behavioral patterns detected in your conversations. Green flags indicate positive patterns like consistent communication and mutual engagement. Yellow flags are cautionary signals worth monitoring. Red flags highlight concerning patterns that may need attention. The app surfaces these objectively—no guessing, just context.
Can I chat with AI about my relationships in subtxt?
Yes! Each tracked contact has a dedicated AI chat feature. The assistant has full context about that specific relationship—historical trends, recent conversations, flags, and metrics—so it can answer questions, help you draft contextually appropriate responses, and provide guidance. It helps you see what's actually there.
Is my conversation data private and secure?
Absolutely. Your screenshots are analyzed and stored on your device only. We never see your conversations. There's no account required, no cloud sync, and no data sharing. You maintain complete control with the ability to export or delete all data at any time.
How is subtxt different from other relationship apps?
Unlike dating apps or social platforms, subtxt focuses on understanding existing relationships through objective conversation analysis. It gives you relationship intelligence, not guesswork. The AI acts as a supportive observer, surfacing patterns you might miss—context, not confusion.
What platforms does subtxt support?
subtxt is designed for iOS and works with any conversation you can screenshot—iMessage, SMS, WhatsApp, and more. The screenshot-based approach means it's platform-agnostic while maintaining complete privacy since you control exactly what gets analyzed.
When will subtxt be available?
subtxt is currently in development. We're focused on building something genuinely helpful rather than rushing to market. Check back soon for updates and launch date.
