Fashionguessr 0 open listings

discussion=https://news.ycombinator.com/item?id=49648754, title=Show HN: Fashionguessr – A Daily Fashion Trivia Game, Hello! I created Fashionguessr, a daily fashion trivia game. Inspired by other daily trivia games like Timeguessr, Connections, and Wordle, Fashionguessr is my attempt at the same thing for people curious about fashion. The game is broken up into three parts: Runway Frames - Users have to guess and identify a fashion show, its brand, its season, and its designer based on a single random frame from the show. Users can use a variety of hints, each more expensive than the last, to reveal more information about the show to help them guess correctly. Trivia - Multiple-choice and short-answer questions to test their knowledge about fashion, the lore, the people, the processes, the history, and everything in between. Sketch - Users get a few moments to look at a fashion item and then are tasked with drawing it from memory. All of these contribute to a score you can see at the end on the last page, which sums everything up. Each section includes explanations, summaries, and sources, so users can get as much insight as possible for every question. There are new questions every 24 hours, and users can go back and play games from days past. I built it to help people learn more about fashion in a fun, low-stakes environment. Learning about fashion can be overwhelming, and I think Fashionguessr can present and package fashion education in a way that's more palatable. Would love feedback on the presentation, UI, accessibility, ease of use, and anything else that comes to mind.

FastRecall, ultra-cheap memory across AI models 0 open listings

discussion=https://news.ycombinator.com/item?id=49735358, title=Show HN: FastRecall, ultra-cheap memory across AI models, Hi everyone! After working on memory at OpenAI, I built FastRecall to solve one problem: using different AI models results in clunky ad-hoc context management systems or lost context entirely. With the model layer becoming commoditized, your context should travel seamlessly across models whether you are using OpenRouter or some other model aggregator. FastRecall offers a simple API that stores your context cheaply and efficiently. In fact, we are so cheap that recalls are entirely free, with generous plans starting at only $2/month! If you use the same model again, FastRecall respects provider caching to save you inference costs. We also have SOTA model-free compaction of context with FlashCompact, in case you don't need full-fidelity context. Hopefully this is useful for some of your projects. Let me know what you think!

Flashviz, Microcontroller flash and RAM 3D visualization 0 open listings

discussion=https://news.ycombinator.com/item?id=49658045, title=Show HN: Flashviz, Microcontroller flash and RAM 3D visualization, I developed this application because in my professional contracting the same pattern of problems came up client after client, how much of the microcontroller or flash is used, and can we do [FEATURE] with what we have. As an embedded engineer the output of arm-none-eabi-size and a spreadsheet tells me the story, but an email or a slide for the client doesn't do it. Another motivator for this project was why not make today look like the future of the movies! You watch tech action movies and there is 3D rotation views of processors, or circuits as holograms right in front of you, or animations of zooming through networks. These movie effects are designed for the exact same thing professional engineers want, to get the info across in an instant to people who don’t know the details. The action hero needs to show the mega-gigatron reactor is almost full, so the green-yellow-red bar graph is almost full, spinning and blinking red with a flashing warning sign suggesting impending doom! While in reality the stakes are less dramatic than that, imagine if the information on how full a system is was conveyed to a PM or VP in the same way? That's the goal of this project, give the engineer the tool to show the boss the details graphically, and make it look good. It's free to use. Screenshot pages without watermark are available for free as well, GDPR compliant no marketing contact with explicit opt-in if you want to chat about professional engineering.

Fluidify 0 open listings

discussion=https://news.ycombinator.com/item?id=49697374, title=Show HN: Fluidify – A wiki of the industrial world being built (post-2026), I built a system with the objective of mapping all the major announced infrastructure and industrial projects around the world. The vast majority of listed projects are expected to become operational after 2026. As you would expect, I used some agents to fill in the map, but for several reasons, some information may not be up to date or as accurate as it could be. The agents provide the initial “breadth,” while the idea is for the community to improve the accuracy over time with what they know: a new source URL, a correction, or a time-stamped picture from the ground. I see several use cases here: - finding a job where industrial activity is getting stronger - finding new logistics opportunities for a freight forwarder, as new industrial plants generate new recurring freight demand - helping select a future site in an emerging industrial cluster - detecting future real estate opportunities where the market hasn’t fully priced in I also see Fluidify as a way to explore beyond the places and projects you would normally think to search for. Most discovery starts with a location, company, or market you already know. On Fluidify, you can simply move across the map and discover industrial activity somewhere you were not looking: a new factory, an emerging cluster, or a region attracting several large investments at once. That can lead to opportunities you would never have thought to search for in the first place. As I invested my own money to build this, contractor data is not available for every project. Mapping and verifying contractors globally would simply be too expensive for me to do alone at this stage. You can message me (email in "About" on the website at the bottom), I’d be glad to show you the data behind the "hidden" tabs.

Fog 2.0: I removed the AI auto-organizing I built my first app around 0 open listings

discussion=https://news.ycombinator.com/item?id=49667476, title=Show HN: Fog 2.0: I removed the AI auto-organizing I built my first app around, Hey everyone, This is my first time posting on Show HN, so hello there. Back in March, I launched my first app on the App Store. It was a notes app that uses Apple's on-device foundation model to organize your notes for you, and I called it Fog. And boy did I learn a lot. Looking at the notes app category and how saturated it currently is, I wanted to try something different. Privacy is #1, so notes should stay on the device, keeping the user in control. Then there was the AI aspect I was using to "automatically organize". So when a user creates a new note, it auto-names the note, generates tags, and tries to do a similarity search against existing folders with the same tags, and in the end the note would land in the folder, all autonomously. Sounds cool in theory and, from my understanding, no other app really did this, in addition to all AI processing happening on device using the same model that powers Apple Intelligence and Siri (works offline too). But this backfired b/c even I started using it less and less b/c I kept forgetting "what was that note called?" "Where'd it go?" "Why'd it move?". Notes and folders were ever-changing, which I also thought was cool but maybe not practical for what a note is meant to be: something to reference. Adjacent to this is how I designed Fog in 1.0. The trend here is Liquid Glass, and I got caught in the hype and overused it to the extent of the app losing readability. I used it everywhere cards, background, animations- and once again it backfired and didn't scale across all platforms. That's backwards from how Apple actually specs it: glass is meant to be the navigation layer sitting above your content, not the content layer itself. Fast forward to today, I took these learnings to share Fog 2.0. A minimalist notes app where Fog suggests, not decides. It still names the note; you can always change or generate a new one. You pick what notes go in a folder, and Fog generates a summary and a name, and if you don't like you can change it. The design now uses SwiftUI native components that scale across platforms and also adapts to different screen sizes; e.g., iPhone Duo support comes for free. The part I enjoyed using the most is Siri AI. Fog now leverages the note App Intent Schema to allow the user to ask/query in natural language, which is what I highlight in a fun demo I made below Overall, this has been an amazing experience for me as a solo indie dev working on something for fun on the side but also hearing feedback from the community. I've gotten a lot of positive feedback but a lot of negative, and it was definitely a new skill taking in both. Also, this is my first time writing this much in a while- a nice breath of fresh air. Fog 2.0 is available on the App Store, free to download and use; your notes are yours and never leave your device Let me know what you think!

Forma ONNX Graph Viewer and Editor 0 open listings

discussion=https://news.ycombinator.com/item?id=49680437, title=Show HN: Forma ONNX Graph Viewer and Editor, Hey all! Most ONNX tooling stops at just "looking". For those of you who know about Netron, it allows you to read the graph but the moment you want to change something you're back in Python either using onnx-modifier or onnx.helper scripts. I wanted to click a node, change an attribute or rewire a connection and actually know whether the model still runs, within a web-page. This is exactly what Forma is! Simply drop an .onnx or .tflite file on the page and a full graph renders. From there you can do multiple different things (for more info have a look at the README in repo) MIT Licensed repo Live web-app: https://forma-ml.vercel.app

Freeform 0 open listings

discussion=https://news.ycombinator.com/item?id=49725268, title=Show HN: Freeform – One click shareable AI generated apps, TLDR: Curious if YC startup requests are a valid take, so I built freeform in a weekend. Storytime: I’ve been working on a startup for a while (another context layer startup) and one night while I had One Piece playing in the background and I was going through YCs request for startups list. I was watching the videos and reading the transcripts when two of them particularly stood out to me: cloud for small apps and shareable apps. Specifically the quote “AI hasn't had its multiplayer moment yet”. I had an idea floating in my head for a collaborative app which I thought would be nice to have and haven’t seen anyone implement anything like it yet (maybe so, I live under a rock). So having a free weekend and a claude pro subscription I started building Freeform. I didn’t count how many hours it took overall but it was about ~4.5 days total. I figured I should post about it since I’m curious if YCs startup direction is… well.. market driven. Anyway, this isn’t a reflection of YCs predictions obviously but more so a loose experiment of my interpretation and implementation of said ideas. Application: Freeform. What is it? I’d loosely describe it as an ai canva since a lot of the direct output is design driven and based on what you see. However, I think the functionality exceeds that as each applet is its own sandboxed environment with persistent storage. This and being able to inject your own api keys or just random links from the web (ie unsplash) results in some pretty interesting creations. The core component I wanted was sharing and collaboration, so I designed the entire idea around sharing links, previewing, and simultaneous prompt based collaboration with versioning. Anyway, try it out I hope you like it :) Try it here: https://sharefreeform.com Some stuff I made: A product page with stripe integration on checkout: https://sharefreeform.com/a/d0e55aff-8aec-45dc-9874-5dc1b943...

GSL 0 open listings

discussion=https://news.ycombinator.com/item?id=49710515, title=Show HN: GSL – I wanted to describe the architecture, not just draw it, I built GSL because I got fed up of building architecture diagrams that couldn't quite capture all of the nuance of the real world. I liked the idea of using a system like Mermaid or PlantUML to represent my systems but there was never really a satisfactory way of describing what was happening. I liked the easy-to-follow syntax of those diagramming tools but they very quickly ran into limitations. When you describe an API gateway component, you can't really say that it belongs in a specific region but also that it belonged in a certain zone of the architecture or which team owns it. And when I described what systems interacted with each other I only had the ability to use a text field to describe all of the metadata about the relationship. Is it HTTPS vs an async lambda invocation? What auth do we need? Something else I wanted was the ability to query the architecture. Surely when you have the full graph of what talks to what, you should be able to pose questions like: * "which customer actions trigger a call to vendor X's API?" * "what will be affected if database Y goes down?" I couldn't really find anything that did that in a way that felt natural. Diagramming tools were either completely visual or too presentation focussed to express what I wanted. Existing graph languages felt too clunky or cumbersome. I struggled to find any that worked with sets and querying in a way that felt right. So one rainy afternoon, I decided to see how far I could get with ChatGPT and some ideas - GSL was born! In the repo there is: * A specification for GSL, a language for defining directed graphs with nodes and edges along with set annotations to declare cross-cutting relationships * A specification for GQL, the companion query language * gsl-query - a CLI tool for executing queries on your GSL models * gsl-diagram - a very primitive tool for turning GSL into Mermaid or PlantUML diagrams * A small VS Code plugin for syntax highlighting * Guides, tutorials, documentation * Rich examples (including some non-tech oriented ones) I think GSL has turned into the language that I was looking for at the beginning of the year. I'm starting to use it in my day job. The guides and documentation have been written to make it easier for agents and LLMs to use and my casual use so far has shown some promise. It's still very much an experiment but I'd like to get other people to take a look and see if it's useful for them too. Have I even made the right assumptions and picked the right abstractions? Have you tried to do something like this yourself? You can begin with the "Getting Started" guide, the specs, or just jump right in to the flagship examples. "Example #3: Architecture Across Boundaries" is fairly close to what I wanted to do originally. https://github.com/dnnrly/gsl-lang
