24 alternatives to Prexist
Hey HN I built Prexist, an AI-powered tool that helps founders, PMs, and VCs quickly find out if their startup idea already exists, across 8 major platforms like Product Hunt, YC, GitHub, Crunchbase, and the App Stores. Until recently, running searches across all these platforms in parallel took ~60 seconds. We’ve just integrated Exa AI for search orchestration, and it’s now 3× faster while returning more relevant, semantically matched results. What it does: - Uses AI to understand your product idea and generate smart search queries - Searches 8 discovery and innovation platforms…

Hi HN, I am Jiayuan, and I'm here to introduce a tool we've been building over the past few months: Devv (https://devv.ai). In simple terms, it is an AI-powered search engine specifically designed for developers. Now, you might ask, with so many AI search engines already available—Perplexity, You.com, Phind, and several open-source projects—why do we need another one? We all know that Generative Search Engines are built on RAG (Retrieval-Augmented Generation)[1] combined with Large Language Models (LLMs). Most of the products mentioned above use indexes from general search engines…

As a founder, finding early customers is always a challenge. I'd come up with specific guesses for people to talk to - such "VCs that used to be startup founders" or "Former lawyers who are now CTOs." Running those types of searches typically involves opening dozens of LinkedIn profiles in tabs, and looking at them one-by-one. And, it turns out that going through LinkedIn profiles one-by-one is a daily job for many people. I started building Find AI to make it easier to search for people. I initially started just having GPT review people's LinkedIn profiles and websites, but it cost…

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…

Hey HN, I’m 14 and I’ve been obsessed with startups for a while. I noticed one big problem: most of us (especially first-time founders) waste months building something that nobody wants. So I built Startup Solve — an AI-powered platform that helps you stress-test your startup ideas before you write a single line of code. It includes six tools: ~ AI Co-Founder → brainstorms with you like a smart partner. ~ Startup Oracle → pressure-tests your idea and asks the brutal questions VCs would. ~ Funding Predictor → gives an estimate of whether your idea could raise funding. ~ Idea Incubator → helps…

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!

Hey everyone, I just launched https://FoundersMatch.ai , a tool built to solve one of the most frustrating startup problems: finding a truly compatible co-founder. Instead of matching on just interests or skills, we use: * AI-powered compatibility analysis * Behavioral science frameworks * Startup psychology and proven founder-matching models Why it matters: 65% of startups fail due to co-founder conflict. And it usually takes months to even find someone potentially compatible. Founders Match helps you: * Avoid mismatches early * Get detailed insights before a call * Match based on…

Foundera▲30Most people are not validating their ideas before start building it! I am a 5th time tech founder, gaming included and I built & managed startup accelerator programs. I know lot of things about early stage founders and their pains as I have been there. That is why I am building Foundera. It’s an AI-Native Accelerator for tech builders. Today the problem is; most of the AI coding tools opens with a chat and asking “type your idea and start building”. This is wrong! I want to reduce the time and money spent on ideas that nobody asked for. Try it at https://foundera.app and give me…
