Ask HN: What are you working on?

I'm working on Brain Hurricane (brainhurricane.ai). It's the kind of structured tool I wish I'd had in my career. I was tired of unstructured brainstorming sessions that recycled the same ideas and the passive waiting for a "great idea" that never arrives.
My goal was to create a systematic process. It uses AI to help you generate ideas with proven methods like SCAMPER and Six Thinking Hats, then immediately analyze them with frameworks like SWOT, PESTEL, and the Business Model Canvas. It's about moving from a fuzzy concept to a validated idea with more confidence and clarity.
On a personal level, this project was my way of diving headfirst into modern AI development. I'm building it with Next.js, TypeScript, Python, and Linux, which has been a fun and humbling experience coming from a more traditional enterprise stack.
It's still early, but the core features are live. I'd genuinely appreciate any feedback from the HN community, especially from those who have struggled to turn abstract ideas into something concrete.

I am trying to use wasm/web-workers to execute actions for Git related workflows (think GitHub actions but much lighter). Currently, working otel related stuff and a small engine to run distributed tasks on Cloudflare workers.
I would be incredibly grateful for any feedback – I'm looking to genuinely improve the experience. Specifically, I'm wondering whether it is easy to use and what it lacks.
I have a huge backlog to cover for this, but so far it has been great fun and I have learnt an incredible range of things!
I'm an Aged Care nurse of 13 years, taught myself to code 5 years ago and am obsessed about automating nursing tasks(i.e auditing, funding, quality) because the volume of admin work that is required by Nurses is absurd and the industry is very far behind and very resistant to: change, spending money and technology in general.
I have been shouting into an empty void the last 3 years but that is okay, i am patient.
I mostly focus on standalone, local AI tools that do a task and are open ended(manual file upload) to suit the 20 million different software in aged care. Keep it all as simple as possible and minimal hurdles.
Generally using llama.cpp, Qwen3, python and then wrapping in some sort of ugly GUI or more recently- AutoHotKey. The nurses feel powerful pressing a few buttons with ahk and watching work be done. (Avoids command line, avoids me being paralyzed by front end stuff).
I don't know why i am sharing this as i am way out of my depth here but there you go. If anyone else is in the Aged Care space, give me a shout. *edit because i can't format new lines or spell.
- You have identified a real life problem.
- You are a domain expert.
- You can iterate and test your solutions quickly in a real world environment.
- you are making sane technical choices: keep it simple, use what your user want, use what works.
- you are patient.
- most importantly, your motivation is deeply rooted in yourself.
I share your frustration with change resistance and insane level of complexity in the health care industry, it’s not just nursing. But if you can show people that you are improving their life, they won’t look back. Proof by the demo is what works.
Keep up the good work, keep being patient and change will happen.
I'm working on Teletable (https://teletable.app), a macOS app that shows live football & F1 standings/results with a teletext interface (think BBC Ceefax). It's free and on the appstore:
https://apps.apple.com/us/app/teletable-football-teletext/id...
I'm using api-football[0], but its paid. Unfortunately, here's not much free sources available that provide the exact data i want + real-time data.
Every week, an endless number of new podcasts and talks are published. Most get buried before anyone sees them. My newsletter called "Tech Talks Weekly" is a free email that lists all the new talks and podcasts published in the past 7 days across hundreds of conferences (KubeCon, QCon, PyCon, Devoxx, etc.) and podcasts with a few must-watch ones highlighted and briefly summarized.[2]
Also doing yearly “most-watched” compilations (e.g. 100 Most Watched Software Engineering Talks Of 2024 that made it to HN front page) which have been fun to put together.
Started it as a side project to stop missing good talks, but now 7,200+ devs read it every week.

Allows you to listen to live online radio streams.
I wanted something with a minimal and fast UI and none of the other web apps I could find really fit my needs so I built this.
During work I like to listen to online radio so it seemed like a no brainier to make for myself and if others enjoy it to, even better.

A short demo playlist is also available here: YouTube Playlist: https://lnkd.in/dggtt85E
Tech stack: Go, gRPC, KurrentDB, Postgres, Redis, Docker, React, TypeScript, TailwindCSS, Vite, Nginx
Also worked on a project that downloads entire sites from the Wayback Machine at a certain point (or as close to a certain point as possible).
It's been a fun challenge as the games are pretty clustered in terms of scoring, and the games themselves are random with minimal points scored. I'm also not the biggest fan of hockey, so it's been fun for me to see which teams are ranked high.
I've been leaning on AI for the first time which has been interesting; I see a ton of content with AI around web dev, but less around more data science. It's interesting how quickly AI will break a common sense rule, like data leakage. Really fun learning experience!
In terms of platform, I've been having a ton of fun with static sites. Cheaper to host and more secure, all I need is a domain name to get it accessible on the web.
Its been really fun. I've been blogging about it as well[1][2][3] and I've hit the HN Front page twice already. I'm super psyched about it.

This week I’m thinking about whether it makes sense to provide a location history ‘vault’, designed to let users expose their location history to LLM’s as context.
Built entirely with SwiftUI + RealityKit, it’s been an incredible journey into VisionOS and spatial computing.
Here’s the TestFlight link: https://testflight.apple.com/join/tWS4CERT
So I am building this https://www.leaklake.com , any feedback welcome.
Current focus: Ant-ban strategies for higher / lower cost throughput. Trying to identify constraints to calculate feasibility, both technical and financial. This may be slightly controversial here since many are averse to bots and scraping. I’ve actually increased per-request costs because I suspect scraping will become more restricted and less tolerated over time — the supply-side signals point that way.
Ideas I'm thinking about: Since I'm steering away from the higher concurrency/low cost scraping option — the new ideas I'm thinking about are: increasing data granularity, retailer coverage, adding an MCP server to help users query and analyse the E-commerce data they're extracting with the APIs as well.
Background: I’ve been building this solo from India for about four years. It began as freelancing, then became an API product around a year ago. Today, I have ~90 customers, including a few reputed startups in California. For me the hardest parts are social, not technical or financial — staying connected to US working culture can feel inverted from here. I’ve applied to YC a few times and might again.
You get to choose the genres you're interested in, and it creates playlists from the music in your library. They get updated every day - think a better version of the Daily Mixes. You can add some advanced filters as well, if you really want to customise what music you'll get.
Sort of built this because every time I build a multi-agent system, I spend 2-3 weeks creating the same infrastructure: orchestrators that route tasks, database agents with SQL guardrails, retry logic, loop limiting, and cost tracking. Then another week of debugging when things break. I wanted to ship features, not plumbing.
Most frameworks are bulky and complex. You just want pre-built components you can compose like AWS services.
I'd love your feedback.
To simplify this, I created the Home Hue Scene Importer app.
Hue has since introduced a migration option for individual scenes, but I still find it somewhat inconvenient.
The app is now available here: [https://apps.apple.com/de/app/home-hue-scene-importer/id6753...](Home Hue Scene Importer) on the App Store
A recipe collection from Eastern spiritual traditions.
If you follow certain traditions, there may be a certain way to eat and cook.
This is the start of a collecting them in one place.
- Rust Lab Log (https://github.com/bryan-lott/rust-lab-log) a simple CLI to take down notes and timestamp them in a single markdown file. I was inspired by my dad's use of logbooks in chemistry labs growing up so that you can always look back and figure out what went right or what went wrong. Has come in very handy during a couple of incidents.
- LogProx (https://github.com/bryan-lott/logprox) a logging proxy with stupid-low added latency. We had an issue where we were accessing a deprecated version of an API and couldn't figure out where the calls were coming from. The API owner was threatening to turn off our access entirely (long story). The idea being LogProx is to send all traffic through it and create rules to log and/or block calls that match a ruleset. Added latency was so low that I had to drop down to measuring in tenths of a millisecond.
It works on the basis of a whitelist, only apps in there can be run on the phone. It contains a lot of useful tools and is continuously expanded based on user needs.
The difference maker is that the app can't be simply uninstalled. It uses Android's MDM system for that. It can only be removed if you wait for a specific number of days that you choose at installation. So when motivation fails, the app won't.
For anyone curious, all details (and download) are available at https://thekaizenapp.com

It has a rich free tier, simple API, and a client dashboard that is easy to use. I do my best to build a service that I would love to use as a software engineer.
We buy three different lots per product, test at an ISO 17025–accredited lab, and publish all results. If a product doesn’t reach its goal within 365 days, contributions are refunded.
We recently added pooled donations to auto-fund the leading unfunded test and I’m iterating on more readable result summaries.
Would love feedback and product suggestions: https://laboratory.love

The architecture is deliberately minimal: ZeroMQ based broker, coordinating worker nodes through a rather spartanic protocol that extends MajorDomo. Messages carry UUIDs for correlation, sender/receiver routing, type codes for context-dependent semantics and optional (but very much used) payloads. Pipeline definitions live in YAML files (as do worker and client configs) describing multi-step workflows with conditional routing, parallel execution, and wait conditions based on worker responses. Python is the language of the logic part.
I am trying to follow the "functional core, imperative shell" philosophy where each message is essentially an immutable, auditable block in a temporal chain of state transformations. This should enable audit trails, event sourcing, and potentially no-loss crash recovery. A built-in block-chain-like verification is something I'm currently researching and could add to the whole pipeline processing.
The hook system provides composable extensibility of all main user-facing "submodules" through mixin classes, so you only add complexity for features you actually need. The main pillars of functionality, the broker, the worker and the client, as well some others, are designed to be self contained monolithic classes (often breaking the DRY principle...), whose additional functionality is composed rather than inherited through mixins that add functionality while at the same time minimizing the amount of added "state capital" (accent on behaviour rather than state management). The user-definebale @hook("process_message"), @hook("async_init"), @hook("cleanup") etc. cross-cut into the lifecycle of each submodule and allow for simple functionality extension.
I'm also implementing a very simple distributed virtual file system with unixoid command patterns (ls, cd, cp, mv etc) supporting multiple backends for storage and transfer; i.e. you can simply have your data worker store files it subscribes to in a local folder and have it use either its SSH, HTTPS or FTPS backend to serve these on demand. The data transfers employ per file operation ephemeral credentials, the broker only orchestrates metadata message flow between sender and receiver of the file(s), the transfer happens between nodes themselves. THe broker is the ultimate and only source of truth when it comes to keeping tabs on file tables, the rest sync, in part or in toto, the actual, physical files themselves. The VFS also features a rather rudimentary permission control.
So where's the ML part, you might ask? The framework treats ML models as workers that consume messages and produce outputs, making it trivial to chain preprocessing, inference, postprocessing, fine-tuning, and validation steps into declarative YAML pipelines with human checkpoints at critical decision points. Each pipeline can be client-controlled to run continuously, step-by-step, or interrupted at any point of its lifecycle. So each step or rather each message is client-verifiable, and clients can modify them and propagate the pipeline with the corrected message content; the pipelines can define "on_correction", "on_rejection", "on_abort" steps for each step along the way where the endpoints are all "service" that workers need to register. The workers provide services like "whisper_cpp_infer", "bert_foo_finetune_lora", "clean_whitespaces", "openeye_gpt5_validate_local_model_summary", etc., the broker makes sure the messages flow to the right workers, the workers make sure the messages' content is correctly processed, the client (can) make(s) sure the workers did a good job.
Sorry for the wall of text and disclaimer: I'm not a dev, I'm an MD who does a little programming as a hobby (thanks to gen-AI it's easier than ever to build software).
If this isn't something people want then it should be shut down.
The idea is quite simple: improve supply chain security by having a validated mirror of NPM, PyPI, Cargo, etc.
There's a lot of static and runtime behavioral analysis that can be done as a baseline but it will always be possible to bypass since it's a cat and mouse game. I'm therefore also looking into how tooling and maybe LLMs would be able to assist humans in reviews and allow better scaling.
Currently on the more academic stage of the project (research, talking to professors and connections in industry, etc.) to hopefully start off with a good design to iterate off of.
My reference for the project stems from what I saw in Huawei during my internship as they had quite a bureaucratic system to review dependencies and an internal "secure" mirror. The goal is to hopefully generalize it such that supply chain security is accessible to small/medium companies or even individuals.
Building a tool to check your site layout and copy from multiple devices. Uses gpt-5 vision to find inconsistencies in headings/images.
This has been a productive weekend so far. I've recently solved an issue with cron jobs that was driving me mad for ages, and finally feel like I'm close to a first tagged release. I have just popped linting into the GitHub CI.

Most shoppers spend hours to find the right product. We’re fixing that with intent-based search that understands descriptions, images and personal preferences.
We’ve hit 25K+ searches in 4 months, growing 50% MoM, and built our own scraping system that makes product data collection 100× cheaper than existing tools.
Still early, but live. Would love feedback on search quality and result relevance.
PS! There are some products out of stock, this is expected, fixing it right now.
It’s still looking pretty rough around the edges.
Happy to get any feedback :)
This includes a correlation matrix with rolling correlation charts, a minimap, hierarchical clustering, time series detrending, and more. I've improved its design and performance and I'm developing new features to better contextualize the visible subsection relative to the entire dataset.
I've also rewritten the entire project in Svelte 5 (there's still a lot of cleanup to do).
It's a minimalist time zone converter. The real value add, in my opinion, is that it lets you look up multiple locations and add them all to list that updates in real-time. I built this a few years ago but I made a bunch of UX and quality of life changes recently. I have metrics around usage but I would be curious to chat with some users to get their take on how it can be improved.
Finally getting close to relaunch. Sales have been stable but no growth since traffic has been going down this year.
I am rewriting https://createaclickablemap.com/ I started changing some thing last year adding micro services with NodeJs I am using VueJS for the new editor and Laravel for the back-end. Added several features that had plan over the years. I am 98% there and mostly prepping for the migration. Will switch to subscription and add couple of different plans.
In October I finished the PDF parser. It was a big challenge extracting PDF contect with correct paragraph breaks on user's computer locally. I'm gonna write about this soon.
Now I'm working on a web extension that talks to the app that run locally on your system so you can use WithAudio in your browser with very good performance, 100% local and private.
It would be nice also if only one person posts this so we don't end up having multiple posts spaced too close together. I really enjoy the "What are you working on" posts and would hate to see it diluted to nothing.
The premise: stand at any 7-11/FamilyMart/etc, take a photo showing you can see the next store, walk to it, repeat. Chain as many stores together as you can. It sounds silly but Taiwan really is this convenient - you often can see 2-3 stores from one spot. Here[2] one route where you can actually link 7 convenience stores in a row!
This is actually the first game built on our upcoming platform for creating branded games. Figured the best way to test the concept was to make something fun first!
