Show HN: Kaiden – A chat-based health assistant you can talk to

Hi HN!

I recently built Kaiden — a simple chat-based health assistant that helps you log meals, track activity, and get personalized wellness tips through conversation.

It works like a messaging app, but instead of tapping through forms, you just say things like:

- “I had eggs and toast for breakfast.”

- “How many calories did I eat today?”

- “Remind me to drink water every morning.”

Kaiden replies like a coach, tracks your habits, and even sends you morning and evening messages. Everything is currently 100% free, no credit card needed.

# Why I built this

I’ve always found health and food tracking apps tedious — they ask for too much, and give too little back. I wanted something frictionless and more helpful. So I built Kaiden around a conversation model, using AI to make logging and feedback feel natural and lightweight.

# What I’m looking for

Does the chat feel useful or gimmicky?

Is this something you'd actually use for your own health?

What would make this a tool you return to every day?

You can try it here: https://kaiden.chat

Would love your honest feedback — and I’m happy to share more under-the-hood details if anyone’s curious.

Thanks!
