I built an online API Client using NextJShttps://news.ycombinator.com/item?id=43390946A few weeks ago, I launched a little product that was useful for me, and I figured it could be useful for others too: Trevo, an online API Client—completely open-source and free from logins or any of that stuff.The idea? A lightweight browser alternative to Insomnia and Postman, mainly for quick sandbox environment tests (which was my use case).I built the most basic version and got a lot of interesting feedback, so I decided to give it a proper revamp. What started as a quick test to see if something that worked for me would work for you has now turned into a much more polished tool. So, my online API Client is packed with cool features, and besides the style overhaul, we now have:Request history (well, this was already there); Ability to save requests in folders (!); WebSockets support (you can test a server and send/receive messages directly); Option to save requests in cURL format (so you can test them in the terminal); And last but not least, I exposed the API with a mini-doc, so Mar 17, 2025 5:46 PM

Fuzzy Matching on Mac: Missing No More?https://news.ycombinator.com/item?id=43367289## Mac Users Got Left Out, Until NowFor individuals utilizing Microsoft Excel on Mac systems, a significant limitation has persisted: the absence of Microsoft’s Fuzzy Lookup Add-In, a feature restricted to Windows versions of Excel. This exclusion has hindered Mac users from leveraging fuzzy matching, a critical technique for identifying approximate matches within datasets, directly within their preferred spreadsheet software. This gap in functionality has compelled many to resort to inefficient workarounds or alternative platforms, often at the expense of productivity with budgetary considerations.Flookup Data Wrangler emerges as an indispensable solution, specifically tailored to address this need for Mac users. Operating as an add-on for Google Sheets, Flookup delivers robust fuzzy matching capabilities alongside advanced data cleaning tools, making it an essential asset for professionals managing data on Mac devices.

Show HN: A big tech dev experience for an open source CMShttps://contentfoundry.com/Hey HN! We're building an open-source CMS designed to help creators with every part of the content production pipeline.We're showing our tiny first step: A tool designed to take in a Twitter username and produce an "identity card" based on it. We expect to use an approach similar to [Constitutional AI] with an explicit focus on repeatability, testability, and verification of an "identity card." We think this approach could be used to create finetuning examples for training changes, or serve as inference time insight for LLMs, or most likely a combination of the two.The tooling we're showing today is extremely simplistic (and the AI is frankly bad) but this is intentional. We're more focused on showing the dev experience and community aspects. We'd like to make it easier to contribute to this project than edit Wikipedia. Communities are frustrated with things like Wordpress, Apache, and other open source foundations focusing on things other than software. We have a lot of community ideaMar 7, 2025 5:24 PM

Show HN: Automatically Turn PDFs into Fillable Formshttps://detect.penpusher.appMy hobby project is building a form filling assistant for complex forms, but it turns out that not every PDF form is digitally fillable. A lot of PDF forms are still made with the expectation that you print and fill them by hand. To fix this, I trained a series of models that detect where form fields _should _ exist, then built this utility to turn them into interactive forms.In my experience it's the best tool for the job across nearly every form. It ended up being super useful and pretty close to free to run (thanks Modal!), so I've hosted it as a free utility at https://detect.penpusher.app.There are some advanced settings as well, so if you're not getting good results with a specific pipeline you can try tweaking those, or let me know and I'd be happy to take a look. Plus the next round of model training is focused on improving handling of scans.Hope this is useful and happy to answer any questions!Mar 5, 2025 5:28 PM

Why I believe some of you and your not-yet-AIs should deal/train with Pareidoliahttps://news.ycombinator.com/item?id=43133721In your context, it sounds like you're looking at cases where a pattern appears to indicate a mechanism but actually just distracts from real data.

But I’ve often wanted for a centralized place to access the latest financial reports from major corporations—something that goes beyond editor-curated content to cover the broader market.Platforms like SeekingAlpha, Quartr, Finchat, Earningshub are fantastic, but they’re often complex, costly, and designed for in-depth stock research.

Reimagining CRMs with AI: A Bootstrapped SaaS Founder's Journeyhttps://news.ycombinator.com/item?id=42590047I wanted to share the lessons I’ve learned bootstrapping a SaaS aimed at solving a problem I saw firsthand in the real estate CRM space.My journey started in customer support at a real estate CRM company, helping agents on their worst days—when their software failed them and they lost commissions because of it. These conversations taught me more about the frustrations, struggles, and needs of agents than I ever could’ve learned from surveys or user research alone.Later, I moved to outbound sales (yes, cold-calling!) and saw what made some agents light up and others groan. My bosses wanted me to focus on closing deals, but I cared more about whether the product would genuinely help someone.I realized the CRM space wasn’t just broken, it was outdated and bloated, causing agents to spend more time managing the tool than selling homes.A few lessons I learned along the way: 1.

Why AI Needs to Pull Its Head Out of Its Ass and Get Bret Victor-Level Controlshttps://news.ycombinator.com/item?id=42536727Let’s get real: AI sucks at editing. Sure, it can spit out rough drafts—cool faces, surreal landscapes, or random game ideas—but when you try to refine that output? Forget it. You’re left yelling at the screen, “No, AI, I said tweak the lighting, not turn my Roman villa into a goddamn UFO hangar!”This is a problem. A big, hairy problem. If AI can’t do high-fidelity editing, it’s not a tool—it’s a toy. What we need are controls that give us real power over the details, like sliders, dials, and live previews. We need Bret Victor-level genius design to take AI from half-baked gimmick to something useful.AI Can’t Handle Nuance Here’s the thing: AI can generate stuff. But the second you try to make a specific change—like, “Make this face look more Emily Blunt and less John de Lancie”—it completely craps the bed.Why? Because that kind of adjustment isn’t simple. It’s about tweaking hundreds of tiny details: bone structure, skin texture, eye shape, expression, all working together. AI doesn’tDec 29, 2024 1:52 AM

Ask HN: Genesis, the next seven days, for your Holiday enjoymenthttps://news.ycombinator.com/item?id=42497524I asked a chatbot to speculate the next seven days after Genesis, and here's what it came up with:The Next Seven DaysAnd on the eighth day, the Creator observed the wonders of the Earth: the mountains towering over the plains, the rivers snaking toward the seas, and the creatures teeming in joyous harmony. Yet, the Creator saw the humans, who marveled at all that surrounded them but knew not their place.Thus, on the eighth day, the Creator bestowed unto humanity the gift of curiosity, so they might explore the depths of the oceans, the vastness of the skies, and the secrets of the soil. And humanity, filled with wonder, began to name all things, for in naming they found meaning.On the ninth day, the Creator gave them the seed of ambition, so that they might not merely inhabit the Earth but shape it to their needs. From sticks and stones, they built tools, and from tools, they built shelter. The animals watched from a distance, puzzled and wary, for this ambition was unlike their own.OnDec 23, 2024 8:57 PM
