PreApp
Review agent-made work. Return feedback to Agents.
What it does
PreApp turns Agent-made reports, decks, Markdown and HTML into review links. Reviewers comment on content without an account. Feedback returns with version and location via Skill, CLI or MCP to Codex, Claude Code, Hermes, OpenClaw, WorkBuddy or another Agent.
Publish, share, version and feedback workspace for agent-generated deliverables.
Your agent publishes and revises, you confirm and share, reviewers give feedback with no account. Every publish is a version — the link never changes. A reviewer left feedback on the exact HTML state. The owner turned it into a clean revision brief. The agent pulled it and published the next version on the same link. Not another static host — the publish, share and feedback loop for agent-generated HTML. Publish a single HTML or Markdown file, zip or directory from any environment via CLI / API / MCP, get links back as JSON. Every publish becomes v1 / v2 / v3; the latest link never changes and old versions stay viewable. Viewers read cleanly, reviewers leave lightweight feedback — separate…from preapp.app

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
