I’m working on a web app called Pitch coach. It has vocal exercises and shows you in real time whether you are flat or sharp. Everything is saved in browser so there’s no account creation. Coolest part is that you can upload a song and it will split the vocals, recognize all the vocal pitches and then you can sing along. Crazy how much you can do in the browser these days! https://pitch-coach.pages.dev

cascade-editor.pages.dev - a free node-based image editor that works with image sequences and has an associated desktop app. It’s pretty incredible what you can do in browser these days with wgpu and wasm- everything is cross compiled from rust.

This is dope! I made https://github.com/zacharyfmarion/openscad-studio to do a similar thing. Using AI for CAD has so much potential but sometimes the model failing to understand spatial concepts is really tilting

Show HN: Pixel Forecast – a pixel-art weather app

zacharyfmarion — Tue, 10 Feb 2026 19:52:54 +0000

Hi HN,

I just released an iOS weather app called Pixel Forecast.

Instead of static icons, it shows a pixel-art scene that changes with the real weather. Each condition (rain, snow, cloudy, clear, partly cloudy) has its own animation, and the scene also shifts between morning, afternoon, evening, and night.

All the animations are perfectly looping and modeled in Blender. I’m currently working on additional scenes and animations.

App Store link: https://apps.apple.com/ae/app/pixel-forecast/id6758243523

Would love any feedback on the visuals, UX, or features you’d expect from a weather app.

Show HN: OpenSCAD Studio – AI-assisted OpenSCAD editor (macOS alpha)

zacharyfmarion — Fri, 17 Oct 2025 16:05:37 +0000

Built this as a "Cursor for OpenSCAD" after getting frustrated copying code into ChatGPT to debug complex operations.

Features:

  - AI copilot that reads code/diagnostics and makes validated edits
  - Monaco editor with tree-sitter auto-formatting
  - Live 3D mesh viewer + proper 2D mode with SVG viewer

Privacy / models

  - By default uses  via your API key; no server of mine
  - You can disable AI entirely; all non-AI features run locally

Status / limits

  - Early alpha, macOS only today (Tauri app). Windows/Linux planned.

Looking for feedback on

  - Editing/formatting defaults for larger codebases
  - 2D SVG workflow (is it useful / what’s missing?)
  - Must-have features before Windows/Linux

Show HN: Flamechart MCP – Analyze Go, JavaScript, Python Traces with Flamecharts

zacharyfmarion — Thu, 05 Jun 2025 14:57:15 +0000

Hey HN!

I made an MCP server for analyzing performance traces (locally or hosted on https://flamedeck.com). It works best with models that have strong image understanding - o3 + o4 mini have been my go-tos. Would love any feedback you have!

Quickly take heap profiles on Hermes. More flexible and reliable than the current chrome devtools integration.

One of my favorite books! Shows you how connected statistical inference and machine learning really are.

I posted something similar on my blog (http://zacharyfmarion.io/machine-learning-with-amazon-ec2/) not too long ago. Would be nice if there was a tool that set all of this up for you!
