Prompt Fixer

An editor for your AI prompts — see exactly what's missing

Prompt Fixer launched on August 20, 2026 with 2 votes, #5,788 of 23,274 launches that month.

What it does

I kept writing lazy prompts and blaming the AI for bad answers — so I built an editor for my prompts. Prompt Fixer marks up your ChatGPT/Claude prompt like a real editor would — showing exactly what's missing (role, context, format, tone, audience, constraints) with a before/after score and clickable annotations explaining each fix. Rule-based, not an LLM wrapper — instant, free, no sign-up. Paste, fix, copy. Built after one too many "write me an email" prompts that got me nothing useful.

Paste what you'd normally type into ChatGPT or Claude. We'll mark it up like an editor would — free, nofrom prompt-fixer-3.onrender.com

  • Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  • 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…
