Ask HN: What are you working on? (September 2026)
Tritium - the legal IDE for desktop and web.
We're building the document viewing and editing layer for a number of AI native law firm startups.
Web preview: https://tritium.legal/preview
WASM example: https://tritium.legal/wasm
We actually offer source access here, too: https://tritium.legal/source
Why? There's no why. The world doesn't need another Markdown editor. I still made one.
Everything is on-device, purposefully human-centric without being anti-AI. I built this because I wanted to work on a project that I could sweat the details unconstrained by deadlines, investors, etc.
I was frustrated with other writing experiences, and like most I gravitated to Apple Notes due to simplicity, but I still missed so many things. As someone that's spent the last 2 years immersed in Cursor, Codex and CC, I wished some of their input behaviors existed in a regular text editor.
For example, you can use / to add styles, or : to add emojis, shortcuts like < 3 for a heart, - > for an arrow, and so on. It honestly feels great.
Is it radically different than other editors? I don't think so. But I think it's well executed across every dimension possible.
Maybe one different thing: multiplayer. It's live editing like google docs, but P2P using WebRTC and strong cryptography. The limitation here is that you can only share a file while having it open yourself.
Great care was taken to performance and portability. This is one of the areas where I spent a ridiculous amount of time simply because I enjoyed pushing the limits of the stack. While using you will notice that rendering, GPU, RAM and bundle sizes were heavily optimized. The Mac app is < 50mb.
Very soon, I'll launch an iOS version with iCloud sync. In the future, I might launch basic AI features. If you miss a great text editor in your life, give it a try.
Basically a simple pizza status tracker for small German fabricators and craftsman. You define the process, instantiate it per customer order who receives the link to a status page with a possibility to subscribe to status notifications as well. The benefit is that people don't call you anymore asking for the status of their order, saving time.
It's a pretty vanilla rails app running on a hetzner vps.
DoodleMate is a multimodal storytelling canvas that exposes students to the basics of animation, character design, and story creation. Starting from paper drawings, it creates rigged versions of your characters that can talk, walk, dancing, sing, etc and you can create scenes out of it.
It doesn't use any generative AI whatsoever. Just computer vision and animation algorithms.
I’ve always had the same problem with website blockers: I might need YouTube for a tutorial related to what I’m working on, but allowing YouTube also means allowing every unrelated video. Same with Hacker News - I might need to look something up for work, but I shouldn’t end up reading the front page for the next 30 minutes. Most blockers operate at the domain/app level, but whether something is distracting really depends on what you’re trying to do.
With Nono, you describe what you intend to work on at the start of a focus session. It then uses an on-device model to look at the active window in that context. So a relevant YT video can stay open, while an unrelated video gets blocked.
The tricky part right now is the model. It needs to be small and fast to run continuously, while still being capable enough to understand the context and not annoy you with false positives.
ai slop is an instant turn off for me. i would never be convinced with such low effort website.
Tracking newly opened restaurants, bars, hotels, shops and other places.
Currently covering 30,000 places across 1200 cities, with photos, opening dates and location data.
I believe it is the first eCommerce platform where all the products have date as an important feature and where the search and navigation are by date - the thinking being it could help people find interesting and original birthday presents and anniversary gifts. I've also built it as a multi-vendor platform so it can hopefully live on once I've sold my things. Note that I'm the only seller and it is all UK based at the moment, but it has just been launched.
I've a blog post with more info at https://michael-lewis.com/posts/vintagepresents.com-date-bas... if anyone is interested.
I'm building a CLI tool for Emacs Org-Mode files. It features JQ-like querying, editing files, capturing tasks, viewing agenda, an AGILE-like board and many more.
{:find [?title ?director ?rating ?card ?shout]
:where [[?m :movie/title ?title]
[?m :movie/vote-average ?rating]
[(str ?rating) ?rating-str]
[(concat ?title ": ") ?title-colon]
[(concat ?title-colon ?rating-str) ?card]
[(lower ?title) ?lowered]
[(concat ?lowered "!!!") ?decorated]
[(upper ?decorated) ?shout]
;; joints
[?cr :crew/job "Director"]
[?cr :crew/movie ?m]
[?cr :crew/person ?p]
[?p :person/name ?director]]}
You can edit a movie's ?title and ?rating through the ?card column for instance. It supports arithmetics too (to the extent that it's logically feasible of course).The systems engineering V-model provides us with a general-purpose approach to solving difficult problems. It comes with an array of proven and trusted standards and document-oriented processes.
Given the number and detail of these documents and processes, automating some realisation of V-model is almost trivial. Tools like Codex and Claude Code are hardly less reliable and trustworthy than human engineers, and the existing standards already contain ways of mitigating the impact of imperfect work performed by error-prone agents.
The generality of this "Autonomous Systems Engineer" gives it a genuine claim to be something approaching AGI. Certainly it enables us to tackle much bigger and more challenging problems than we could with only the LLMs on their own. (Yes, it's "just another harness-of-harnesses", but that doesn't mean that what it can do isn't significant).
In addition to providing automation of high-integrity engineering practices, my project also provides a disciplined communication layer that sits on top of A2A or other similar protocols, enabling small agent-first engineering organisations to exchange well-defined highly-assured documents and accelerate b2b collaboration - enabling "swarms" of small, agile businesses to take on larger and more demanding challenges than they would be able to individually.
