Show HN: A Virtual friend that checks up on you, every morning

https://www.jurnai.site
1•anonyMusk•6mo ago
I vibe coded Jurn AI - a notion integration that lets your diary / journal talk to you.

It works by generating feedback from user’s last night journal. This feedback is then sent over mail to the user every morning with the intention of motivating them.

The idea is to give a friend/family like feel, daily checking up on you based on how your day went by.

To vibe code, used following agents, each with its own dedicated folder to store their system prompts and progress.

Frontend engineer - knows how to build a nextJS website. Responsible for building the user onboarding ramp.

Backend engineer - works with python and fastAPI. Help built the entire server side.

Program Manager - knows the requirements and the deadline. Helps keep a track of pending pointers.

Product expert - Understands what we are building and why. Helps refine Content on the landing page - optimizing layout for max user conversion. Helps in simplifying decisions

Infra Engineer - To be honest, I wasn’t able to use much of agent’s help in this. Their knowledge was outdated when it came to resolving platform specific bugs.

What do you think about this project?
