This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass What I Built Most nature apps try to keep you looking at your phone. WildLens was built with the opposite philosophy: make the screen the shortest part of your outdoor experience. WildLens is an open-source field companion and naturalist guide designed for hikers, curious neighborhood walkers, biology students, and families exploring local parks. It does three core things: ...

EchoQuest is an outdoor adventure web app that gamifies real-world exploration to get people off their screens and into nature. Players customize their field ranger avatar, activate GPS tracking, and receive procedural quests like the Canopy Crafting Quest. With "Pocket Mode" enabled, users explore completely eyes-up: spatial audio and voice prompts guide them to physical landmarks. When an item is found, integrated camera vision leverages open-weight multimodal models to identify and validate ...

I open a Thursday review and the page already looks finished. A side panel holds a free draft of the hero. It claims the contrast passes, and it wrote the alt text. I ask who measured the color pair on the real screen. Nobody answers, and the publish button is still armed. Would you press it on a sentence you cannot trace? That quiet is the decision I care about today. I own the call, and a keyboard user may miss contact. I can still hold the URL before it goes public. People are arguin...

Most radar charts pull in SVG path math or a JavaScript charting library. You can skip both. With st-core.fscss v2 , a spider (radar) chart is: an FSCSS array of scores (0–100) polar coordinates stored as CSS variables ( --st-sxN , --st-syN ) shapes drawn with clip-path: polygon() rings and spokes from gradients No canvas. No SVG. No chart runtime on the critical path. Source: github.com/fscss-ttr/st-core.fscss Here’s how it works 1. Data ...

Vickrey: A Birdwatcher’s Journal That Can’t Be Quietly Rewritten This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass What I Built I'm from Kenya, where birdwatching is a beloved pastime. BirdLife International's country profile counts about 1,059 bird species here, 49 of them globally threatened and 10 found nowhere else. Kenya also sits on the African-Eurasian flyway, so roughly 170 species arrive each year from Europe and Asia, acco...

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass What I Built Offline Nature Quest is an AI-powered outdoor exploration companion designed to help people spend less time staring at screens and more time discovering the world around them. The idea is simple: instead of using AI only to answer questions on a screen, what if we used it to encourage people to go outside and explore? The app generates small nature-based challenges, suc...

I built Payload Haven , a free collection of developer utilities that process tool inputs in your browser. No account or upload is required to use the tools. Here are three workflows you can try with sample data. 1. Compare JSON values instead of formatting Suppose an API changes from: { "status" : "pending" , "user" :{ "name" : "Ada" }, "tags" :[ "api" ]} to: { "tags" :[ "api" , "private" ], "user" :{ "name" : "Ada" },...

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass What I Built Parallel is a map-first storytelling platform for discovering and sharing stories tied to real places. A single location can hold many independent story chapters: history, personal memory, local legend, fiction, and editorial pieces. Instead of scrolling a feed, you open a map, pick a place near you, and read what people have said about it. Visits are self-reported, so the a...

Submission for the Hacktoberfest Open-Source AI Challenge – Week 1: Touch Grass What I Built Finding somewhere to go outdoors shouldn't require browsing through multiple websites, filtering endless map results, or scrolling through hiking forums. Touch Grass is an open-source, AI-powered outdoor discovery application that lets users search for trails, parks, and running clubs using natural language. Instead of navigating multiple filters, users can simply ask: ...

Hi HN! We've been working hard on Atlas Runa and it's time to share it! We built it to target three key complementary aspects of learning a language: 1. Comprehensible input - Atlas Runa learns your lexicon and then tracks it, which lets us find comprehensible input for you. This works well already. You can start reading real texts and get reading volume much earlier than you would ever be able to with textbooks! 2. The attention effect - we track your mistakes and what you forget and make sure...

Ever since hearing about the interesting key-based algorithmic approach to AI text watermarking (Google SynthID and the one I don't know the name of from Anthropic) I was curious about just swapping in synonyms. Built something fun to explore it. I suspect the watermarking from these labs actually goes off more than single-token assessments, and there's no public validator I can find to actually assess Synonymizer score against the watermark. But I thought it was fun to play with. Kind of an aut...
