What it does

It’s an AI-powered validation tool that pressure-tests your idea before you commit your money. Instead of generic advice, it runs category-specific validations—whether you’re building SaaS, a local business, consulting, or education. The product will surface red flags, blind spots, and risks. You can refine your idea and re-run the validation to see if those risks improve. You’ll get a report, an actionable roadmap, and a premortem comparing your idea to failed products with similar patterns.

Stop building products nobody wants. IdeaGrit runs 4 validation workflows to validate your startup idea, find your ideal customers, and map your competitive landscape — instantly.

Replace the messy chatting thread with a structured pre-mortem. Find the right hard thing to commit to. You won't get the same answer opening a bakery as starting an online B2B SaaS. Different idea, different playbook. Choose the workflow that matches your idea — SaaS, local business, consulting, or education. Each one runs a specialist set of AI agents built for that exact context, so the advice is actually relevant. IdeaGrit marks the risky parts of your report, shows what might break, and lets you refine your idea prompt so the workflow reruns with better context in minutes. After every validation, IdeaGrit synthesises the full report into a 4-phase action plan — what to do before you…from ideagrit.foundersailab.com

    I made a tool to help collect and validate startup ideas2024 · keepmyidea.app · ▲38

    Hey HN, I’m Kyrylo. I recently created a small tool that lets you gather, refine, and validate SaaS/startup ideas using AI. I used to jot down my product ideas in a note apps, but it wasn’t very practical for collecting feedback or refining them. So, I built this tool to make the process easier. Here’s how it works: 1. Enter a brief description of your idea. 2. The app uses AI to generate project details. 3. Share your idea via a link that includes a feedback form. It’s pretty straightforward, and I’d love to hear your thoughts or any suggestions!

    I accidentally built a startup idea validation tool2025 · validationly.com · ▲15

    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/

  • With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
