The Monolog project was conceived to elevate the practice of journaling from a static, passive activity into a dynamic and interactive dialogue for self-discovery. I engineered a full-stack, cross-platform mobile application featuring a personalized AI companion powered by OpenAI's GPT-4. The app analyzes user entries for mood and themes, offers contextual insights, and visualizes personal growth over time. The outcome is a sophisticated and production-ready mental wellness tool that demonstrates a successful fusion of advanced AI integration with an intuitive, user-centric mobile experience.
01 About The Project
Monolog is a next-generation mobile journaling application designed for meaningful self-expression and personal growth. Guided by the philosophy "Let it go, write it down," the app provides a safe, non-judgmental space for users to capture their thoughts, feelings, and goals.
The core challenge was to move beyond simple note-taking and create a truly interactive partner for reflection. By integrating the power of OpenAI's GPT-4, Monolog offers users a personalized AI companion that understands context, identifies patterns, and provides intelligent insights, turning a monologue into a productive dialogue for mental wellness.

02 From Thoughts to Insights: Key Features
Noli AI Companion & Conversation Analysis
At the heart of Monolog is Noli, a personalized AI companion that learns from user patterns to provide tailored reflections. The system performs real-time mood and theme detection, understands the context of past entries, and generates intelligent summaries, helping users connect with their thoughts on a deeper level.
Multi-Modal Journaling for Every Need
We designed Monolog to be versatile. Users can engage in structured Morning Planning for setting intentions, Evening Reflection for daily review, Brain Dumps for free-form thought capture, or even use Voice Recording for hands-free transcription and analysis. Each mode is tailored for a specific reflective purpose.
Smart Analytics & Progress Visualization
Monolog translates raw journal entries into actionable insights. The app features 5-level mood tracking, automatic theme categorization, and progress visualizations like streak tracking to encourage habit formation. Weekly AI-generated summaries help users identify recurring patterns and celebrate their personal growth.

03 Designed for Serenity & Focus
The user experience was paramount. We created a minimalist, distraction-free writing environment using a calming color palette (Primary: Sage Green) and carefully selected typography (Display: Romana, Body: Akkurat) for readability and elegance. The interface supports both light and dark themes with WCAG-compliant contrast ratios, while subtle animations and haptic feedback create a delightful and accessible user journey.
