Vently: An AI Diary Companion Built for Reflection, Not Therapy

Journaling can be a powerful tool for reflection, but many people struggle to keep it as a consistent habit. They may not know what to write, how to express their feelings, or how to make sense of daily experiences. Vently was created to explore how AI can help lower that barrier.

Developed by CMKL students Kittiphon Kijpinyochai, Suppakorn Krabtong, Nutthawat Assawapongsakorn, Teerathath Chothsithwanith, and Paphungkorn Charoenkit, with Dr. Natnatee Dokmai as advisor, Vently is a mobile AI diary companion designed to help users turn everyday conversations and emotions into structured self-reflection.
The team built a mobile application where users can talk with an AI companion, record daily feelings, and generate diary-style reflections from their conversations. Rather than asking users to begin with a blank page, Vently provides a conversational entry point. Users can express what is on their mind, and the system helps organize those thoughts into reflective journal entries.

A key feature of the project is its memory layer. By keeping track of previous entries and interactions, the app can help users revisit patterns over time. This makes the experience more personal and continuous, while also raising important design questions around privacy, safety, and responsible AI use.

The team made an important product decision: Vently is positioned as a reflection and wellness companion, not a therapy tool. This distinction matters. AI systems that interact with emotions must be designed carefully, with clear boundaries around what they can and cannot provide. Vently focuses on helping users reflect, not diagnosing mental health conditions or replacing professional support.

From a technical perspective, the project combines mobile development, AI conversation design, memory management, backend data handling, and human-centered interface design. The challenge was not only to make the system work, but to create an experience that feels supportive without overclaiming what AI can do.

Vently shows how CMKL students engage with both the possibilities and responsibilities of AI. It is a project about more than app development. It is about designing technology that responds to human needs with care, clarity, and ethical awareness.
