Products that do what Prom.dev – Prompts that simulate Hacker News (and a tool to share them) does

We’re Heather and Matt, and we want to invite you to Prom. Prom is a simple place to share the prompts you’re proud of and discover ones other people actually use. The idea came out of a lightweight internal library we hacked together for our team earlier this year. Before that, we had “good prompts” on Slack or Google Docs. We wanted a dedicated place for prompts, and somewhere people can post what’s working for them, compare approaches and models, and see what “good” looks like in the wild. The tech is, well, nothing fancy, but intentionally lightweight. Flask backend, Bootstrap frontend.…

    Hi, I'm a high school teacher from Australia and I've built what I'd like to think is a pretty nifty ChatGPT powered presentation tool for teachers. I'd love it if you could have a look at it and give me some of your feedback. I don't think there's much overlap with the HN crowd and school teachers, but I've been coming here for many years and thought I'd post here and see what you all think. Check it out if you have a minute and I'd be super happy to hear your feedback too. https://www.slidehero.ai/ You can jump in and have a play with the tool all you like ;) Cheers, Eli

    I built this out of frustration as I lead the development of AI features at Yola.com. Prompt testing should be simple and straightforward. All I wanted was a simple way to test prompts with variables and jinja2 templates across different models, ideally somthing I could open during a call, run few tests, and share results with my team. But every tool I tried hit me with a clunky UI, required login and API keys, or forced a lengthy setup process. And that's not all. Then came the pricing. The last quote I got for one of the tools on the market was $6,000/year for a team of 16 people in a…

    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…

    Hi HN! I'm Prithvi—my co-founder Frances and I launched Promptless almost a year ago here (https://news.ycombinator.com/item?id=43092522). It's an AI teammate that watches your workflows—code changes, support tickets, Slack threads, etc.—and automatically drafts doc updates when it spots something that should be documented. Frances and I really appreciated the feedback from our first launch. Today we’re launching Promptless 1.0, which addresses our biggest learnings from the last 12 months. I also made it way easier to try it out. You can tag @promptless on any open-source…

    Hey HN Community, We're excited to announce the integration of the newly launched ChatGPT API into Promptly - a platform designed to make prompt management and sharing a breeze for developers. With Promptly, you can easily test out different prompts and model parameters for various providers, and quickly share prompt snippets together with parameters and generated output. It's like CodePen or JSFiddle, but for prompts! In addition to that, Promptly also allows you to create high-level endpoints on top of provider APIs (such as Open AI, DreamStudio, and more) with templated and versioned…

    Social media these days feels like swimming through a feed of AI generated slop rather than actual human thoughts. Sometimes I wonder what the prompts behind the posts are. I bet there's more creativity going into the prompts than the final content that actually gets shared. What if people just shared their prompts, and the completion was rendered on-demand, client side? Disclaimer: This is a vibe coded proof-of-concept, not a functional service, built in the no-code builder Mocha. It's seeded with a few fake posts. You can create your own posts but they're just saved locally on your own…

    Hi HN, I built Prompt Builder (https://www.promptbuilder.space/) because I was frustrated managing complex AI prompts in plain text boxes. The core idea: instead of one giant textarea, you compose prompts from draggable, reorderable blocks. Each block can have its own XML/custom tags, visibility toggles (so you can A/B test sections), and duplicates. Key technical details: - Live compiled preview: the right pane shows the exact string being sent, updating as you drag/toggle blocks - Dynamic variables: define {{var_name}} once, use across blocks, change in one…
