AI journaling app
The AI journal that reads what you actually wrote
Nuju pairs a 30-second mood check-in with written reflection, then uses AI to surface what is repeating underneath your entries - moods, themes, and relationships that shift your week.
Who Nuju is for
- Overthinkers who want a fast way to capture a thought before it spirals.
- Mood tracker users who want AI that interprets what is moving, not just collects it.
- People between therapy sessions who want a private space for reflection support.
- ADHD and low-energy days when 30 seconds is the only journaling that actually happens.
How Nuju works in 30 seconds
- Tap your mood and energy and optionally write a few sentences.
- Ju reflects on your specific words, not a template, and surfaces the feeling underneath.
- Patterns appear over time as Ju connects moods, themes, and people across entries.
What makes Nuju different
- AI reflection on your actual writing, not a generic prompt response.
- Mood and energy paired with text so trends stay grounded in real context.
- Weekly summaries surface what kept repeating across your entries.
- Voice journaling for days when typing feels heavy.
- Four coach personas - Gentle Guide, Tough Coach, Wise Sage, Fun Friend.
- Encrypted storage, signed media URLs, no journal data sold, no AI training on your entries.

Frequently asked questions
What is an AI journaling app?
An AI journaling app is a journal that combines your writing with mood data and uses AI to reflect on what you wrote. Instead of a blank page, you get a private read on what is happening underneath an entry, plus pattern detection across weeks.
Is Nuju free?
Yes. The Ju Gets You reveal and core mood and writing flow are free. Paid access unlocks full history, 30-day trends, weekly summaries, voice journaling, AI memory, and the relationship mood map.
How is Nuju different from a generic AI chatbot?
A chatbot replies to a single message. Nuju is a journaling system: it pairs writing with mood and energy, remembers context across entries, and surfaces trends you cannot see from any one conversation.
Does Nuju replace therapy?
No. Nuju is a reflection and self-awareness tool, not therapy, crisis care, or medical treatment. It works best alongside real-world support when you need it.
