PrompTessor▲125After 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…

Hi HN, I’ve been spending a lot of time vibe-coding with LLMs and kept running into the same bottleneck: translating a vague idea into a prompt that produces usable output without multiple correction cycles. Most of the time wasn’t spent coding, but refining prompts. Adding constraints, clarifying intent, restating context, fixing assumptions. It felt like a repeatable preprocessing problem rather than something that should require manual effort every time. So I built a small tool that takes rough, unstructured input and rewrites it into a more explicit, structured prompt optimized for…

Nowadays, a common AI tech stack has hundreds of different prompts running across different LLMs. Three key problems: - Choices, picking from 100s of LLMs the best LLM for that 1 prompt is gonna be challenging, you're probably not picking the most optimized LLM for a prompt you wrote. - Scaling/Upgrading, similar to choices but you want to keep consistency of your output even when models depreciate or configurations change. - Prompt management is scary, if something works, you'll never want to touch it but you should be able to without fear of everything breaking. So we launched Prompt…

Hey HN, Since late 2021, I’ve been building apps using only AI models. Over time, I realized the real problem wasn’t how good the coding models were, but how you write and structure your prompts. When I vibe code, I make a looooot of typos or write unclear prompts. I often find myself reverting to old versions because the AI misunderstood my prompt and made incorrect changes. But in reality, it’s usually not the AI’s fault. It’s my prompt. That’s why I built PromptDC. It enhances your prompts with one click, without leaving your web-based platform or local editor. Just write your prompt in…

Hi HN, we are the founders of Relari (https://www.relari.ai). We launched our LLM evaluation stack on HN a few months ago (https://news.ycombinator.com/item?id=39641105), which is now used in production by AI teams at companies like Vanta and PwC. We have since expanded to directly optimizing parts of an LLM pipeline using a data-driven approach. In particular, we see a lot of potential in the Auto Prompt Optimization—which could be an attractive alternative to fine-tuning in many cases—to use data to align LLMs for domain-specific tasks. Here’s a demo video:…

hi. i'm dulra. i strongly believe in moving humanity forward. we're at a tipping point: ai-driven applications are generating hundreds of millions of prompts daily, costing organizations millions in token fees and creating governance nightmares. every wasted word compounds at scale—across chatbots, summarizers, code assistants, and virtual agents—making prompt efficiency not just a nice-to-have, but a strategic imperative. by treating prompts as first-class assets, we can drive down llms usage costs by up to 60%, eliminate compliance risks, and unlock new multi-model workflows that keep us…
