Conversational AI Journaling App

Hey HN,

I’ve been working on a journaling app that takes a different approach via conversational AI: instead of writing or typing, you speak to an AI that listens and talks back, helping you reflect on your thoughts and feelings in real-time.

It’s designed for people who struggle with traditional journaling. A live transcript is available to revisit and annotate later.

The web app is free and still early. I have a lot of ideas for features, but instead of building in isolation, I’d rather shape it with real users—figuring out what actually helps rather than just guessing.

On the tech side, I tested a bunch of options and landed on DailyBots for orchestration, Deepgram for Speech-to-Text, Cartesia for Text-to-Speech, and OpenAI’s 4o-mini for the LLM—balancing latency, quality, and cost.

I’d love to hear your thoughts—what would make something like this truly useful to you?
