Show HN: I made a running app that turns your runs to a virtual garden

I started running 5 years ago and it completely changed me. Recently, I decided to train for my first marathon and needed something more than just tracking my runs to motivate me. I noticed all the apps currently available are just trackers and route finders, but nothing has solved the problem of consistency.

Show HN: AI for Building Design, Planning, and Permitting

Saw Spacial recently — it's an AI tool that helps figure out what can be built on a piece of land, based on local zoning rules.

You enter a parcel and it generates 3D massing, site plans, and other planning details in a few minutes. Seems like it could be super helpful for early-stage architecture or development work.

So I keep rebuilding the same setup: tracking events, enriching sessions, summarizing
