Ask HN: What apps are you building?

It's a pipeline for generating dense crossword puzzles with a Rust grid fill engine and optional Claude based clue writing and QA processes.

I use it to generate the crossword puzzles on https://wordfuzz.com/. The quality is already good for smaller (5x5 and 9x9) puzzles. I'm working on improvements for larger 15x15 NYT style puzzles.

I'm also working on Ekorbia: https://github.com/ekorbia/ekorbia-desktop. It's a lightweight, MIT licensed, Rust/Tauri desktop app for private local LLMs with a prompt library, chat overlay, ephemeral chat, model comparisons, and folder/RSS/URL watches.

The builds are unsigned but you can build it yourself to avoid the warnings. It has a bundled engine on macOS and requires an OpenAI-compatible server on Windows/Linux. Any feedback would be appreciated.

And a tool to combine some windows on the computer has also been developed, which can quickly open multiple specified application windows according to the set layout through shortcut keys.

There is also an application that meets my own bookkeeping habits.

I've been a writer for over a decade and a half. I'll often rewrite intros and other sections a half-dozen times, or cut quotes and bits that don't quite fit, only later to wonder if an earlier take was better.

I built Reproof to solve this. Every paragraph is versioned, so you can rewrite paragraphs and switch between the takes to see which sounds better. There's a clipping pane on the bottom, to cut things and save them just in case you find a spot to include them later. And there are a bunch of writer-focused features: Write and copy text in either rich text or Markdown, open two documents side-by-side and find/replace between both, selective find/replace to edit only some of the results, command palette to search across everything, daily versioned backups, and more. And lots more to come.

Nearly every other writing app is a digital piece of paper with linear paragraphs. Reproof instead lets you explore the best way to write what you're trying to say.

There's no personal information necessary whatsoever (when you signup, you're assigned a randomly-generated account number, which is what's used to login). You can get 2h of a free trial _if_ you pass a local and private proof-of-work captcha. Then you top-up your account with a payment, and that's it (you can even use crypto via our ProxyStore partnership [1]). No subscription, no data from you is stored in your database.

This month we reached 250 monthly active accounts, _nearing_ 300, but _hopefully_ that'll happen next month. It's much harder without a subscription and social media ads, but we wouldn't want it any other way.

Oh, you also get the source code after 12 months (BUSL -> AGPLv3 in 2 years).

The rate-limits are good enough that you can build automations on top. It also comes with MCP server.

The API is open to all, not just in India. Feel free to use.

* Dashboard for docker and web servers

* The web servers serve WebSockets and http from the same ports

* The web servers provide simple proxies and can even proxy TLS connections over non-TLS intermediaries

* Provides resource graphs for each docker container and web servers provide simple

* Lists all machine processes, services, user accounts, ports by tcp or udp, hardware information, and more

* Provides tools for testing http and WebSocket connections

* Provides remote shells allowing the user to choose from all installed shells on the machine

* supports both Linux and Windows

* Is just written in TypeScript and designed for high performance

  Hi {{user.name}}{{@type string}}

I started it ~a year ago and it died like side projects do. Months later, building something completely different, I caught myself wishing for exactly the tool I'd abandoned, and since then it's completely vacuumed up all my free time.

The best compliment I’ve received so far is from friends who grew up in the same era I did: when I fullscreen the browser, a few of them assumed it was a virtual machine running the real thing.

I’ve tried hard to capture the spirit of what made QBasic great: built-in IDE help, an interactive, line-by-line interpretive environment, no compilation step, and a fast feedback loop. So far, every program you write in the simulator can be taken to an old 386 and will run exactly the same.

It started out as a bit of a mad scientist experiment, but I’ve already put close to a hundred hours into it.

Silly video demo (take a PEEK - see what I did there?)

This project originated out of two complaints that I have with trying to learn with AI: first, it becomes increasingly difficult to revisit previous ideas or concepts as sessions grow longer and second, richer learning experiences are often flattened into a wall of text.

Personal Tutor keeps course, progress, quiz results, coding attempts, etc. together locally so that the agent can see this history when building upon a course. It also ships a library of teaching components, SDK, CLI, and local UI so that agents can spend more tokens on teaching quality rather than component generation.

Would love to hear any feedback!

In an ideal world it would be good enough to put meal planning on autopilot.

Getting pretty close to public beta if anyone is interested.

There’s more to it than that of course, and you can use variables, folder breaks, etc, to fully customize how it sets up the project.

It’s great for ensuring consistency in project structures, which is especially useful in a larger company with a lot of employees. It was originally created for video editors but it’s agnostic and can be used for any type of project.

Existing app is here: https://www.digitalrebellion.com/posthaste

It is designed to have a minimal learning curve, and has faster performance than React due to the use of web components.
