24 alternatives to A tool to help you write more reliable prompts
Hey HN! While writing prompts for a few projects recently, a couple of friends and I realised that writing prompts today is like writing code in a txt file - it sucks and there is no tooling to help you. So we decided to hack on a tool to help you fix this - https://optimist.varied.ai/ It is literally a hack rn but we already find it useful for writing prompts. That said we'd love to talk to folks who are writing serious prompts everyday and see how the product can be better. Also the only reason the waitlist is there, is running this is super expensive like $100/day for…

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 working on an experimental tool that helps you use GPT to work on your codebase. I'd love to improve the tool if there's interest. New ideas welcome! I think this could also be useful for experimenting with other types of recursive prompts. It’s a little bit Swiss Army knife and a little bit skynet: https://github.com/ferrislucas/promptr From the README: Promptr is a CLI tool for operating on your codebase using GPT. Promptr dynamically includes one or more files into your GPT prompts, and it can optionally parse and apply the changes that GPT suggests to…

I got frustrated watching everyone focus on fancy AI frameworks while basic prompts were failing. After spending months writing prompts, I realized that many of them were ineffective—often due to unclear instructions, missing edge cases, and ambiguous language. Built this tool that transforms vague prompts into clearer, more effective prompts, leading to better results from large language models (LLMs). Just input your original prompt, and the tool will give you an improved prompt version.

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:…

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…

I was working on a project that involved indexing GitHub repos that used really long prompts. Iterating over each section and figuring out which parts of the prompt led to which parts of the output was a quite painful. As a frontend dev, I kept thinking it would be nice if I could just 'inspect element' on particular sections of the prompt. So I built this prompt debugger with visual mapping that shows exactly which parts generate which outputs. Now that context windows are getting huge, working with massive prompts should not be as difficult. Planning to open source this soon, but I'd love…

PromptForge▲10Hi HN, I recently built PromptForge — a minimal, developer-first web app that helps you generate high-quality GPT prompts from just a few structured fields. Why? As a developer, I often found myself rewriting similar prompts manually. I wanted a faster and more reliable way to generate optimized prompts for various tasks — coding, debugging, idea generation, etc. So I built a tool that combines structure, speed, and simplicity. What it does: Select a use case (e.g. summarization, code explanation) Fill out a few fields (context, tone, output format) Get a clean, optimized prompt Save, reuse,…

I made EchoStash. If you’ve ever written a great prompt, used it once, and then couldn’t find it again — I’ve been there too. I kept losing my best prompts in chats, notes, or random documents. Every time I started a new project, I ended up rewriting the same stuff or wasting time trying to remember where I saved things. So I built EchoStash — a simple tool for developers who use AI tools regularly. It helps you save, organize, and reuse your prompts. You can tag them by project or tool, and when you need something, just search. The cool part? EchoStash has AI-powered search. You don’t need…

Hey everyone! Along with my team, I've developed a reinforcement learning system that automatically optimizes LLM prompts, complete with a visualization feature to track both prompt structure and learning progress over time. Take a look here: https://nomadic-ml.github.io/nomadic/cookbooks/Nomadic_Promp... Check out our website too:https://www.nomadicml.com/ In terms of how this visualization works: The RL Prompt Optimizer employs a reinforcement learning framework to iteratively improve prompts used for language model evaluations.
