Idea Validation Framework
Preuve AI (Formerly Test Your Idea) validates startup ideas before you build. Describe your concept in plain language and 10 specialized AI agents scan 50+ live data sources to produce a sourced viability report in under five minutes.
Each report covers competitor landscape, total addressable market sizing, demand and trend signals, pricing benchmarks, key risk assumptions, and a composite viability score from 0 to 100. Every data point links to its source - Google Trends, Reddit, Product Hunt, Trustpilot, app stores, and more. If the data cannot verify a claim, it is not included.
A free scan delivers a quick overview with viability score. The Deep Analysis ($29) unlocks all 13 report sections including go-to-market playbook, community signals, pivot recommendations and 3x iterations. The Investor Package ($499) generates five investor-ready deliverables: pitch deck, investment memo, financial model, DD checklist, and pitch prep guide.

Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes. RS-X is framework-agnostic. While it can drive UI... - Source: Hacker News / 5 months ago
I like htmx, LiveView, React and Solid. They are great at different points, so I try to combine them in Solv (Stateless Offline-capable LiveView) and write a prototype to show the benefits. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is... - Source: Hacker News / 8 months ago

Then fine-grained reactivity is added to achieve efficient DOM updates + minimal payload size.... - Source: Hacker News / 8 months ago
In the code editor tab (powered by StackBlitz), navigate to the env.ts file and enter your OpenAI key. Run npm run generate in the terminal to see how @autoview generates TypeScript frontend code from example schemas derived from both TypeScript types and OpenAPI documents. - Source: dev.to / over 1 year ago

I built Test Your Idea, an AI tool that scans startup ideas against 40+ live data sources and scores their viability. After 2,500+ scans, I started noticing patterns that challenge a lot of the startup advice you see on Twitter. - Source: dev.to / 4 months ago
