Preflight▲77Hey HN, I’m a product designer on a payments team. Every time we were close to shipping a feature, we’d run a bug bash in a giant Google doc or spreadsheet: copy the spec in, write the test cases, ask people to mark Pass/Fail, paste screenshots, then manually turn everything into Jira tickets. It worked, but it always felt a bit painful. Instead of another heavy test management tool, I wanted something that feels closer to the tools we actually like using. More Linear/Notion, less old-school QA. With Preflight, you paste your product requirements and Figma link and get an initial…

I was working on validating some of my own project ideas. While trying to find how to validate my idea, I realized the process itself could be turned into a tool. A few late nights later, I had something that takes any startup idea, fetches discussions, summarizes sentiment, and gives a quick “validation score.” It’s very rough, but it works, and it’s already making me rethink a few of my own ideas. It's still a work in progress. I don't actually know what I'm doing, but I know it's worth it. Honest feedback welcomed! Live demo here: https://validationly.com/

Howdy friends. I've been a zero to one product manager for 12 plus years and along the way I kept borrowing pieces from different discovery frameworks until I had a methodology of my own, one that actually raises the odds of an idea succeeding. This does not replace user interviews obviously, but it leads you in the right direction. Looking forward for your feedback

I am working on this because I am always afraid of building things that people don't actually want. I let agents role-play analysis the idea, quote and debate with each other. Still working on the output quality, every feedback is priceless. Pls try it out!

b4zero▲7It started out when I thought about how to help founder to validate their idea, not just coming up one but how to turn the idea into real business by not relying on AI but making them more involved into their product, understand the market by doing research, check what user want. It's like a checklist, a step for someone who want to get start. This is not an AI to go tool, it's a tool to drag user back to reality, simple but important. I don't think I'm gonna make money with it so I decide it will be a free to use. Use referral code "beyondzero" to sign up. Thanks

I'm a PM who got tired of the same cycle: do a bunch of customer interviews, dump them in a doc, tell myself I'll synthesize them later, never do. So I built Mimir as a fun side project for myself and my day job. You paste in your raw feedback — interviews, support tickets, survey responses, whatever... and it pulls out themes, ranks them, and tells you what to build next. Every recommendation links back to the actual quotes so you're not just trusting a black box. There's a real pipeline underneath that does extraction, clustering, synthesis across sources. You can chat with your data, push…

Hey HN, I'm a founder at Ovlo a supply chain company.I had a problem. After every batch of customer interviews/research/feedback sessions, I'd run ideas through an LLM to help me decide what we should build next. Except it was obvious to my cofounder I wasn't really validating anything. LLMs are incredibly good at agreeing with you in subtle ways, especially when you feed them context that already reflects your thoughts. I'd ask "Does this make sense?" and get a beautifully worded essay about why yes, obviously, this is the best thing ever. I was using AI as an echo chamber without…
