I built PrompTessor – a tool to help people write better AI prompts
After countless hours of solo coding, designing, and iterating, I’m both excited and nervous to share my first-ever product: PrompTessor — now live. As someone who constantly experiments with AI tools like ChatGPT and Midjourney, I often found myself stuck in a loop of trial-and-error. The issue wasn’t always the AI — it was often the prompt itself. That observation became the starting point for PrompTessor. This tool doesn’t just optimize your prompt — it analyzes it. It gives you: - A prompt score - A breakdown of strengths and weaknesses - A fully optimized version of your prompt - And…
In plain words
PrompTessor is a tool that analyzes and improves prompts written for AI systems like ChatGPT and Midjourney. It evaluates prompts across six dimensions—clarity, specificity, context, goal, structure, and constraints—then provides a score, identifies strengths and weaknesses, delivers an optimized version, and offers improvement guidance. The tool is designed for anyone who regularly uses large language models and wants to reduce trial-and-error iterations by writing more effective prompts from the start.

After countless hours of solo coding, designing, and iterating, I’m both excited and nervous to share my first-ever product: PrompTessor — now live.

It gives you: - A prompt score - A breakdown of strengths and weaknesses - A fully optimized version of your prompt - And even a step-by-step guide on how to improve it PrompTessor evaluates your input across six dimensions: Clarity, Specificity, Context, Goal, Structure, and Constraints — helping you communicate more effectively with any LLM. It’s free to try, and my main goal right now is to gather as much real-world feedback as possible. As a solo founder, honest reactions and suggestions from this community would mean the world to me. Try it here: https://promptessor.com Every piece of feedback is incredibly valuable, and will help me shape PrompTessor into something truly useful. Thanks for reading! Happy to answer any questions in the comments.

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…

Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…
