    Hi HN, I'm pleased to share Promptspot, an open-source (Apache License 2.0) project that helps automate testing of large language model (LLM) prompts against an array of input data. Modern LLMs offer an enormous amount of leverage if you "teach the bot to fish" — i.e. simply prompt it with both a "system prompt" (which typically doesn't change often) and a dynamic input, which is often application state, search results, recent activity, user profile data, etc. Existing playgrounds and prompt management systems often lack the rigor and flexibility required for this dynamic approach — and as…

    At testup.io we have been working for a while to bring artificial intelligence to the field of test automation. Just a few years ago, the primary challenge laid in accurately identifying UI elements following minor structural changes, such as updates to IDs or paths. The emergence of Large Language Models (LLMs) raised the bar for what it meant to be smart. Now, we anticipate the robot to do lots of things autonomously, such as retry in cases of unresponsiveness or handle minor error reports. A more challenging, but soon expected feature, would involve the test robot navigating your web shop…

    Hey HN, I built a tool to solve my biggest LLM workflow frustration: context switching. The idea came from trying to meta-prompt in Cursor, I found myself constantly jumping to a browser or dedicated AI app just to improve a prompt. This copy/paste/tweak cycle was a huge productivity killer. I wanted AI to integrate seamlessly into my workflow, not disrupt it. That's why I built Promptive. It's a native macOS app that lets you select any text, in any application, and run a custom LLM prompt on it with a global keyboard shortcut or right-click and select the action in the…
