Ask HN: What Are You Working On? (Nov 2025)

What are you working on? Any new ideas that you're thinking about?

When someone dies, you don't get even one extra second to access the documents and information they meant to share it with you.

Trying to fix this problem with Eternal Vault.

Link: https://eternalvault.app

Another thing thats in early alpha right now is CapKit, AI professional captions for short form videos

Eternal Vault is interesting. I would for sure use something like this. However, only if there is a strong story how the vault will survive 20+ years, even if your company is defunct. I do see the pieces scattered around the website (backup to Dropbox, etc), but this story needs to be front and center.

Working on a curated Hacker News x AI newsletter.

There’s so much nuance in HN threads that often gets missed elsewhere, so I decided to put start this newsletter.

Initially started as an experiment for 10 issues to see ig it gets traction, 6 issues in it’s at 68 subs and probably will continue for unlimited time period.

Link to the latest issue: https://eomail4.com/web-version?p=01b6f55e-bb2d-11f0-bcb3-f3...

Raptor - a new (Free software) way to build things like:

* Disk images

* Liveboot isos

* Container images (docker/podman)

Many build products are supported, with more on the way:

https://chrivers.github.io/raptor/builders/index.html#compat...

It uses a syntax that is inspired by Docker, but significantly enhanced.

Take a look at:

Built a local-first Kanban board with Tauri (Rust + Svelte) after getting frustrated with SaaS tools and basic offline options. Stores data in JSON files you control, full keyboard-first UX, parent/child tasks, release management, and it's blazingly fast with localStorage + background sync. No telemetry, purely local. Curious what others prioritize in personal task tools. Seems like there's a gap between "todo.txt" simplicity and Jira complexity.

I am building https://arabicworksheet.com, AI powered Saudi Arabic learning app for expats who work and live in saudi arabia. 100% FREE. It generates printable worksheets based on your level, dialect and topics.

I am also building an app for kids to make their arabic learning fun, rewarding and enjoyable. Do try and share your feedback. TIA

I've been working on a 3D voxel-based game engine for like 10 years in my spare time. At this point it's getting pretty close to being shadertoy for voxels.

https://github.com/scallyw4g/bonsai

I recently ported the terrain generators to the GPU, and increased the visible volume to 1 billion voxels cubed. I did a short YouTube video about it.

https://www.youtube.com/watch?v=bLfgjWsM1PI

I also wrote a metaprogramming language which generates a lot of the editor UI for the engine. It's a bespoke C parser that supports a small subset of C++, which is exposed to the user through a 'scripting-like' language you embed directly in your source files. I wrote it as a replacement for C++ templates and in my completely unbiased opinion it is WAY better.

I've been enjoying the breadth of projects made possible with AI, I've cataloged over 200 of them created in 2025 here: https://jonathanclark.com/posts/ai-coding-million-lines-2025...

A few of my recent favorites: - swim lap counter in html/JS that uses the camera to watch you swim and count laps/timing - video recorder that records your window/desktop and uploads a file to S3 - video conferencing app that allows a 2 year to click on a family member face and initiates a video conference using webRTC, STUN, and browser audio/video capture with automatic bandwidth adjustments (works on all platforms with pure HTML/JS). - CUDA based ray tracer with HTML UI that can trace over 2m rays per second on my laptop for scientific study, allowing real-time display of optical parts. - chat front-end for image models like gemini-pro and openai that take other images and text as references and generate a big library of options to chose from in seconds, I've been using photoshop for decades but I tend to use this more now.

Woah that's a lot of projects. Would be cool if you could open-source some of them.

> CUDA based ray tracer with HTML UI

I'm curious if you mean they're running a raytracer on the back end, and you interact with an HTML UI, or if it runs browserside, maybe via WASM. AFAIK CUDA isn't directly compilable to WASM (yet?)

I have a node middleman that proxies request from an HTML/JS front end to a native cuda process using web sockets. To support multiple windows, the node process process provides communication between two browser windows. This lets me have render a model using 3JS in one window and a ray traced version in another window.

I’m working on a platform to run a friendly competition in “who builds the best reasoning AI Agent”.

Each participating team (got 300 signups so far) will get a set of text tasks and a set of simulated APIs to solve them.

For instance the task (a typical chatbot task) could say something like: “Schedule 30m knowledge exchange next week between the most experienced Python expert in the company and 3-5 people that are most interested in learning it “

AI agent will have to solve through this by using a set of simulated APIs and playing a bit of calendar Tetris (in this case - Calendar API, Email API, SkillWill API).

Since API instances are simulated and isolated (per team per task), it becomes fairly easy to automatically check correctness of each solution and rank different agents in a global leaderboard.

Code of agents stays external, but participants fill and submit brief questionnaires about their architectures.

By benchmarking different agentic implementations on the same tasks - we get to see patterns in performance, accuracy and costs of various architectures.

Codebase of the platform is written mostly in golang (to support thousands of concurrent simulations). I’m using coding agents (Claude Code and Codex) for exploration and easy coding tasks, but the core has still to be handcrafted.

Ooooh, neat, I had a similar idea, like an AI olympics that could be live streamed where they have to do several multi-stepped tasks
