Show HN: MDX Docs – a lightweight React framework for documentation sites Hey HN! I’m Ezra, the creator of MDX Docs. I built this because I wanted a fast, simple way to document components using Markdown and React together with MDX. The goal was to keep things really straightforward: pages are just MDX files, and they map directly to routes. You can write docs and drop in React components right alongside them without much setup. It also includes a CLI: npx create-mdx-docs@latest my-docs I’ve been using it to spin up docs sites quickly, and it’s been a really nice workflow so far. Curious how others are approaching documentation for components and internal tools these days. Happy to answer any questions. https://mdxdocs.com March 19, 2026 at 10:03PM

Show HN: Mavera – Predict audience response with GANs, not LLM sentiment Mavera is an audience intelligence API. Give it a message, product prototype, or creative asset and it returns a predicted distribution of emotional and behavioral responses across your target stakeholder population. This is the best way to test your assumptions before you spend or push anything live. To show this in practice, we ran all 101 Super Bowl LX ads through Mavera on game night: https://ift.tt/KwgOaMk. We simulated how audiences would emotionally and behaviorally respond by platform and segment. We returned a distribution rather than a single score as part of a full analysis of each ad in under 4 hours. The model is a GAN adapted for language, emotion, and cognition. A generator produces synthetic audience responses and a discriminator validates them against human benchmarks. Scoring follows a feel-think-act framework: emotional activation, cognitive framing, behavioral prediction. We validated scori...

Show HN: Will my flight have Starlink? Hey HN, If you’ve been lucky enough to be on a flight with Starlink, you understand the hype. It actually works! However, its availability on flights is patchy and hard to predict. So we built a database of all airlines that have rolled out Starlink (beyond just a trial), and a flight search tool to predict it. Plug in a flight number and date, and we'll estimate the likelihood of Starlink on-board based on aircraft type and tail number. If you don’t have any trips coming up, you can also look up specific routes to see what flights offer Starlink. You can find it here: https://ift.tt/loYSCpF . - I wanted to add a few notes on how this works too. There are three things we check, in order, when we answer a query: - Does this airline have Starlink? - Does this aircraft body have Starlink? - Does this specific aircraft have Starlink? Only a few airlines at all have Starlink right now: United, Hawaiian, Alaskan, Air France, Qatar, JSX, and a handfu...
