www.dolphinwhispers.com I working on the Android app to chat with dolphins using underwater whistles. The current version works well and is about to be used with free dolphins near Spain. We do not support captivity and we don't want our work to promote captivity or to increase revenues from captivity.
Hi HN — I’m Gerome, and I’m working on CodinIT.dev.
TL;DR: CodinIT.dev is a local-first, open-source AI full-stack app builder that turns natural-language prompts into prototype → production web apps. It supports local/self-hosted workflows, connects to databases (Supabase), includes an integrated terminal and git automation, and plugs into 19+ AI providers so you can iterate fast. Download desktop app at https://codinit.dev .
A few quick facts
What it does: Generate full-stack code from prompts, preview instantly, and deploy anywhere — built for indie hackers who want full control of there code without vendor lock ins (open source).
Where the code lives: active repo and org on GitHub — org name is codinit-dev.
How to try it: download and run locally; the dev flow runs with pnpm run dev and serves locally from your machine.
Progress & current priorities
Stabilising the live code execution sandbox and improving safety/UX for file uploads and agent orchestration.
Tightening integrations with community LLM providers and adding more framework templates.
Improving contributor docs and reducing onboarding friction so people can run it locally without hurdles.
If you want to poke around, try the app or the GitHub org and open issues/PRs. I’ll hang around to answer technical questions here.

Bringing back a podcast I last did 20 years ago. My, how things have moved on!
I've been taking some time off from https://gethly.com, as majority of functionality I wanted to implement and offer to customers is done, so it's mostly just some tweaks here and there.
I was pondering doing something in regards to decentralised consummation of content. I am beginning to see how various websites are walling off their content and centralising everything whilst also monetising access to it for themselves and kicking content creators out, forcing them to run their own websites and use multiple backup platforms(mostly the dying youtube).
So I was thinking about flipping it on its head and instead of going to different websites to consume this content, like youtube, twitter and whatnot, people would have a single program to aggregate it instead. Then it occurred to me that this is what RSS/Atom was made for, kind of. So I am just letting the idea marinate for a bit and maybe next year I will look into it. Mastodon might have some good concepts in it that I want to look into and also come up with some standardised way for richer content that creators could provide beyond RSS to make it more palatable and easier consumable for users.
tl;dr not much this month :)
I don't have anything to show for it yet, but I'm rebuilding my dotfiles from scratch with a (hopefully) reusable framework that I want to open source some day. I don't know if it'll be useful to anyone else as I have very strong opinions about how this kind of stuff works, but hey, maybe someone else will find it useful. I'm inspired to do this because I realized the other day that computers....aren't fun for me anymore? So I'm taking the opportunity to make my computer mine again rather than continuing to rely on VSCode and all the automated config my company drops on our machines.
In other news, my first astrophotography rig is _finally_ mostly fully put together, and I'm going to try to go out and do some captures tomorrow night!
I cannot say what I'm working on because it will be downvoted. Only pointless gimmicks which do not compete with the tech oligopoly can get any traction nowadays.
If I make a really good AI coding platform which saves people hours compared to existing platforms and provides more security. The chance of success is 0 because it's competing with incumbents.
If I make an app which allows cats to order food and back massages from their owners, this has a high chance of success.

Working on improving the data pipeline for https://iplocate.io - an IP intelligence service I've worked on since 2017. A couple of recent focuses:
1. VPN and proxy detection. We already track dozens of providers, but we can do better here. There's also a bunch of metadata we collect as part of this process which we don't currently surface, so I'm looking at what else we can bring to our databases and free API.
2. Better detail and evidence on how we build and test our own geolocation database, which we create from scratch. There's been a recent trend of misinformation about geo accuracy, including from some other providers, so I want to better explain the accuracy (and inaccuracy) of various techniques, our policy for when we prefer certain data, and so on.
(Open to partnerships for any folks looking for a new provider!)
I mentioned this a few months ago, but have made progress since - I'm working on an alternative to subscriptions for online publications. Instead of subscribing to entire publications / blogs, publishers would register their publication on this network and configure thresholds and pricing. Add a bit of code to the site and a paywall will show up, allowing readers to pay for individual articles. The prices would be minimal, amounting to less than a dollar in most cases. i.e. reading articles using micro-transactions
I know it's been tried before, but I thought I'd attack it with a few different angles - web based, no chrome extension, thresholds to help verify the article is worth it, extensive use of an aggregator to help with discovery and validation.

Advent of Code challenges
I'm soon to beta my first macOS app: AlgoMommy. AlgoMommy helps you organize your video clips prior to editing them in Final Cut Pro / DaVinci Resolve / etc. It replaces the manual and time-consuming process of "filing" your newly-recorded video clips (CLIP_5213.mp4, CLIP_5214.mp4, ...) into a sensible folder hierarchy (Wedding/B-Rolls/, Wedding/Reception/, ...), so that you can focus on creating and your content.
This has been a fun project so far for me:
* First time using Claude Code. CC has made writing code fun again (I'm an experienced software developer, with - gasp - over 20 years of professional experience).
* On macOS, WhisperKit + Apple Intelligence (SpeechAnalyzer) is a powerful combination for offline transcription.
If you're interested in joining the beta, feel free to send me an email: [email protected]. The software is working now, but the documentation and website ( https://www.algomommy.com/ ) are unfinished, so I'd like to provide direct support to any interested beta users.
My twins (in high school) and I are building an AI study buddy.The idea is simple. A peer-level “study friend” you can work alongside, ask questions, and stay on track with.
It’s not doing anything ChatGPT or Claude couldn’t do. The goal is packaging it into something that feels a high-schooler would actually want to use when they’re studying.
We are also using this as a weekly project to learn the abstract stuff. Product thinking, design, pricing, marketing, and how to turn a vague idea into something real. Each week the kids prioritize a feature, research it, write up the idea, and then we build (or cut) it together.
Our stack is Claude Code, TypeScript, React and it's hosted on Cloudflare Pages for frontend + Workers for API.
No login or credit card required to try this out. We welcome your feedback.

A small tool that does one thing: publish Markdown and give you a link—no accounts, no setup, no project scaffolding. Paste or write Markdown, click Publish, and you get a human-readable URL you can share immediately. You can update or delete the page later using the same link.
The idea came from frustration with how oddly hard it still is to put a Markdown document on the web without turning it into a repo, a static site, or a login-gated doc. JotBird is editor-light but publishing-first, and I’m now exploring CLI and editor integrations so it can act as a simple publishing layer for tools people already use.

I'm thinking about creating a brilliant.org clone (the old version, not the current enshittified one) but entirely community-driven and open source: Besides the classical features (create/delete,edit your own problems) you can also have courses and collections: courses are a ordered sequence of lessons and problems, lessons are post-like entities that can contain text, images, animations, embedded videos through links, latex, code, ... Collections are just a ordered sequence of problems (ideally it is a progressively difficult path of problems, but this feature can be used for anything you want). It would also feature a wiki, and eventually a forum for discussing/administering the website.
If anyone wants to join the project, contact me replying at this comment/writing at gbc0 [at] proton [dot] me
Custom Copilot alternative / extension because I no longer believe it is a good idea to let Big Ai determine how you write code with your new helper. Big Tech f'd up a lot of things the last 25 years as we ceded control of our interfaces to them. I don't want to make the same mistake with my primary work tool.

Working on a visual language learning app called Snapalabra!
The idea is simple: You look at an image and describe what you see in your target language. That's basically it!
My reason for building it was that even though I can understand a lot of spoken spanish, I really struggle to construct sentences on the fly when speaking. Doing a few minutes of active learning like this each day really helps remap my brain a little, and I quickly run into situations where I hit a wall and realize I actually don't understand something as well as i had thought.
The app also gives a little feedback on what i have written from an llm, and it also provides clues that I have mapped to each image.
At the moment I am using it mainly for intermediate Spanish and beginner Irish, and personally I find it really helpful for both. Basically learning vocan for Irish, and more serious sentence structure etc. in Spanish.
I know a lot of people absolutely hate the idea of mixing LLMs with language learning, and I can kind of see why, but I personally find it really helpful in certain cases. If you are already doing classes, and consuming content in your target language I think something like this will be really helpful for a 5 minute coffee-break type activity in the morning. Its not a language course and I have not intention for it to be one. Its just a supplementary little tool that helps with getting your brain thinking in a new language and it is free to use.

• I've never been satisfied with music players on iOS, so I'm making the definitive one. It works with every personal media server, in additional to local files and Apple Music libraries. It'll do some stuff that no music player has ever done.
• I open-sourced and released some iOS dev tooling I built for Claude Code that multiplied my personal coding productivity: https://news.ycombinator.com/item?id=46264591 Nobody cares yet, but it makes me feel good to share something cool.
I'm working on a simple IoT visualizer. I built my own domotic system at home (which i hope to turn into a product at some point) and I had the need to visualize the sensor data per room and per floor.
While I was working on the tablet interface (in Godot Engine) I put Claude to work on what after two minutes became a full product on its own with a new file format as well. Tell me what you think! (so far the response is meh...)
