Application Signal – AI That Evaluates Your YC Startup Idea

Take notes on YouTube videos to track ideas and understand viewer engagement for content creators.

I cut the one feature every user asks for, because shipping it would've meant lying to them. I'm building Margin( https://margin.bhairav.ai ), a tool that helps YouTube creators decide what to make next. The #1 request is a number: "this idea will get ~40K views." Every competitor shows one. Users ask for it constantly. I won't build it. Nobody can predict a video's views from an idea. Thumbnail, timing, the algorithm, luck, none of it exists yet when you're validating. Any number I sho

AI platform helping founders validate ideas, build products, raise funding, and grow startups.

As a long time technical founder and startup accelerator program manager, I always thought there have to be a way to gather the early stage startup ecosystem together to help founders in a single platform. We have built Foundera that combines founder profiles, AI startup tools, and ecosystem matching for early stage founders to solve this problem. Try Foundera and tell me what you think, give us some feedback, I think we can improve and grow this app with your feedback in a better way. It's in beta so be nice :)

AI tool that asks clarifying questions and generates verified specifications for coding agents.

I've been building an open source formal methods system (fizzbee.io) for the past few years. Today I'm launching a new app built on the same technology. It performs requirements engineering using formal verification to uncover gaps and produce precise instructions for your coding agents to follow. When given a prompt, it - asks high signal follow-up questions - converts to formal spec and identifies complex requirements gaps - generates validation scenario At the end, it produces a specification document that can be shared with coding agents. In my trials on various projects, it produces working code in fewer iterations. Please give it a try and share your feedback. https://fizzbee.ai/ You can also look at a sample project. https://fizzbee.ai/projects/94bf2869-97a1-445c-8f5d-4445848b...

Create and launch a full app with code, GitHub repo, and marketing materials from a prompt.

This crypto trend tracker was created by Moonshift.io in minutes. Check it out! I have already share 2 apps created by Moonshift, one that parses recipes from recipe site URLs to make a personal cookbook, and one that searches recipes based on ingredients that you input; now to digress from food related apps. This crypto trend tracker was created by a moonshift user for personal use. This is just one more example of what moonshift is capable of. You'll need to sign in to use it. I will

Score startup ideas based on specificity, evidence quality, and risk clarity using AI.

Building NELL Labs -- an AI-native startup validation platform. Instead of generic LLM answers, it scores your idea across specificity, evidence quality, risk clarity, and next-step usefulness, so you know if it's actually validated or just sounds good.

Test startup ideas against AI personas to receive validation feedback in minutes.

Turn your app idea into a detailed prompt for AI coding agents and builders.
@AjonyePaul · X
Your AI coding agent isn't lazy. Your prompts are just too vague. I just launched IdeaPrompt to interview you like a product engineer and catch the edge cases you missed. Try it: What are you building today? 🛠️ #AI #buildinpublic #coding
