    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…

    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…

    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 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.
