Show HN: Get conversational practice in over 20 languages by talking to an AI
Hi everyone,<p>Let me introduce you to Quazel, where we want to enable people to talk their way to fluency.<p>We have all tried various language learning apps and tools, however, one aspect of language learning current services are really bad at is conversational practice. You might get a chat-like interface, but in the end, the conversation partner will only respond with a predefined "if the users say X I say Y".<p>With Quazel that's completely different. In completely dynamic and unscripted conversation you can talk about pretty much anything you want. For example, you can try ordering food at a restaurant and even hold a philosophical discussion with Socrates. Additionally, you can analyze the grammar of your responses or use hints to help you out when you get stuck.<p>We want to change how languages are learned from a grammar-centric approach to a more natural, conversation-focused one.

Show HN: Open Prompts – dataset of 10M Stable Diffusion generations
Open Prompts is the dataset used to build krea.ai. The data comes from the Stability AI Discord and includes around 10M images from 2M prompts. You can use it for creating semantic search engines of prompts, training LLMs, fine-tuning image-to-text models like BLIP, or extracting insights from the data—like the most common combinations of modifiers.

Show HN: TaskTXT, plain text task-timing notepad
I built TaskTXT.com based on my experience timing my tasks. I found that committing to a task before I start helps with my focus, and guessing how long it will take, then timing it prevents me from wanting to give in to distractions because I'm "on the clock".<p>Video Overview: <a href="https://www.youtube.com/watch?v=HOYO0c_D6w0" rel="nofollow">https://www.youtube.com/watch?v=HOYO0c_D6w0</a><p>There's also a Mac app which you can download here: <a href="https://dl.todesktop.com/22080519n9z1jew/mac" rel="nofollow">https://dl.todesktop.com/22080519n9z1jew/mac</a><p>Video overview of the Mac app: <a href="https://www.youtube.com/watch?v=qMs-V5v5gZY" rel="nofollow">https://www.youtube.com/watch?v=qMs-V5v5gZY</a><p>But I didn't want the tool to be distracting, so its based on plain text. That means the UI is very familiar and you can use it for generic notes in any structure you like. When you work in TaskTXT you are working directly on its data format, I made a video about this concept here: <a href="https://www.youtube.com/watch?v=kZdBgVZn5NI" rel="nofollow">https://www.youtube.com/watch?v=kZdBgVZn5NI</a><p>I think this tool is uniquely suited for programmers, so I'd be interested to hear any feedback about the product, or its viability as a business.
Show HN: Figr.app – a multi-user, notepad style calculator (desktop app)
Hi all, just posting an update to my previous Show HN, where I announced a side-project I worked on which was a (web version) of a multi-user, notepad style calculator:<p><a href="https://news.ycombinator.com/item?id=31817997" rel="nofollow">https://news.ycombinator.com/item?id=31817997</a><p>After a couple of user requests (and having a good think about it) I decided to migrate the web UI to create a Mac and Windows desktop app. After using it a little bit, I feel this is a much better experience than the webapp, and reduces a lot of the friction if I wanted to run a few small calculations.<p>You can find the download links below:<p><a href="https://www.figr.app/download" rel="nofollow">https://www.figr.app/download</a><p>For context, Figr was a side project I worked on to get back into coding after being in management for the last few years. It's kind of a cross between popular notepad style calculators (like Soulver, Numi, etc), but also has multi-user editing (like Google Docs). I've got some example templates below which hopefully show what it can do, and hopefully is relevant to the community:<p>- <a href="https://www.figr.app/s/RUNWAY" rel="nofollow">https://www.figr.app/s/RUNWAY</a> - An example to work out your burn rate / runway<p>- <a href="https://www.figr.app/s/LTVCAC" rel="nofollow">https://www.figr.app/s/LTVCAC</a> - An LTV/CAC calculator<p>- <a href="https://www.figr.app/s/CONTRACTOR" rel="nofollow">https://www.figr.app/s/CONTRACTOR</a> - Hourly rate calculator for contractors<p>Opened to feedback, or technical questions if others are in the process of moving, or thinking about moving their webapps to desktop apps, as it's been quite a journey!<p>Thanks!
Show HN: Distributed JMAP and IMAP Servers in Rust
I am happy to announce Stalwart JMAP [1], an open-source JSON Meta Application Protocol server that aims to be scalable, robust and secure. Some of its key features are:<p>- JMAP Core, JMAP Mail and JMAP over WebSocket full compliance.
- IMAP4 rev2/1 support via Stalwart IMAP, an imap-to-jmap proxy [2].
- Scalable and fault tolerant: consensus over Raft, node autodiscovery over gossip and read-only replicas.
- RocksDB backend with full-text search support in 17 languages.
- OAuth 2.0 authorization code and device authorization flows.
- Domain Keys Identified Mail (DKIM) message signing.
- Written in Rust.
- No third-party software required to run or scale.<p>The next item on the roadmap is to release an SMTP server in Rust with the goal of making self-hosting an e-mail server much simpler.<p>Any comments or suggestions are more than welcome!<p>[1]: <a href="https://github.com/stalwartlabs/jmap-server" rel="nofollow">https://github.com/stalwartlabs/jmap-server</a>
