What it does
PostSense helps you optimize Reddit posts for the subreddit you’re posting in. It studies real, high-performing posts to understand each community’s tone, structure, formatting, and timing. Instead of generic advice, PostSense rewrites your draft to match how people actually write in that subreddit, checks for rule and relevance issues, and explains why each change works, so your posts feel native, not promotional.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
