Show HN: Turn any website into a knowledge base for LLMs
I built this tool because I wanted a way to just take a bunch of URLs or domains, and query their content in RAG applications.<p>It takes away the pain of crawling, extracting content, chunking, vectorizing, and updating periodically.<p>I'm curious to see if it can be useful to others. I meant to launch this six months ago but life got in the way...

Show HN: Stempad – Fast Online Scientific Writing
I'm building an online text-editor editor to write and save scientific documents fast. Here's a video of how it works: <a href="https://youtu.be/Hyk8CvCdEWE" rel="nofollow">https://youtu.be/Hyk8CvCdEWE</a><p>As an engineering student, I hated that handwriting was the only viable way to do fast or impromptu scientific writing. It would be the only way to take quick notes in class or in a lab, write an assignment, or create a presentation. Here's a few things I witnessed in academia:<p>* Unsuitable editors: Students attempt to resort to text editors unoptimized for science, such as Notion or Word, to take notes and write assignments.<p>* Slow or expensive software: Students, teachers, and researchers using high-friction and high-cost tools for writing<p>* Messy class notes: Professors upload pictures of hastily handwritten class notes as supplementary material<p>The list could go on. I believe that the ability to quickly document scientific ideas with a keyboard would be a huge QOL improvement for anyone learning or doing science.<p>I recently launched the ability to export Stempad documents to LaTex. I tested it by rewriting part of a paper I found online (Metabolic scaling in small life forms by Marc E. Ritchie & Christopher P. Kempes) and exporting it. You can try the editor and export yourself using the post url. The export button is on the top right of the page. In case you want to see the result directly, this was it: <a href="https://www.overleaf.com/read/zjccqbjdyhtc#6e146c" rel="nofollow">https://www.overleaf.com/read/zjccqbjdyhtc#6e146c</a><p>Feedback is really appreciated! If anyone thinks they might find Stempad useful, let me know and I'd love to get in touch.

Show HN: A video editing SDK that runs in the browser
Hello HN,<p>Video content is more popular than ever, but the toolkit for creating such content is a bit behind. You usually have to rely on a server for rendering whenever you want to create a video editing project in the browser. This means uploading content to a server, coding complex filters and effects, and more.<p>My friend and I spent a year developing an SDK that handles all these complexities and offers an easy-to-use interface for developers. The SDK works entirely in the browser, manages memory efficiently so it can run even on a 7-year-old Android device, supports GLSL effects and transitions, handles captions, and much more.<p>We also created a custom video editor UI interface using the SDK to showcase its speed and flexibility. You can see the video editor embedded on our landing page: <a href="https://rendley.com" rel="nofollow">https://rendley.com</a>.<p>As for the tech stack, the SDK was built using TypeScript, Pixi.js, C++, FFmpeg WASM, and WebCodecs. The UI interface was created using Stencil.js and MobX.<p>The SDK is called Rendley SDK and it is live on npm: <a href="https://www.npmjs.com/package/@rendley/sdk" rel="nofollow">https://www.npmjs.com/package/@rendley/sdk</a><p>To get started, follow this guide: <a href="https://docs.rendley.com/installation" rel="nofollow">https://docs.rendley.com/installation</a><p>If you want to embed the pre-made interface, follow this guide, it’s literally a few lines of code: <a href="https://docs.rendley.com/video-editor" rel="nofollow">https://docs.rendley.com/video-editor</a><p>If you have any questions about the product or any feedback, feel free to write them below, and I’ll be more than happy to answer them.

Show HN: Create diagrams of complex data flows in software systems
Hello HN,<p>It has been a while since I contributed to the web, so I decided to get back in shape and publish "something".<p>This app is a POC of "what if diagrams were more dynamic".
I'm a software engineer by trade, and with conventional tools, I often times struggle to explain flows of data in complex software systems.<p>I got inspired by video games like The Incredible Machine and Factorio, as in some ways, software systems tend to become Rube Goldberg-esque machines ;)
As a side quest, I also wanted to craft diagrams faster than text-based tools (ex: mermaid), as I am always forgetting their syntax.<p>If you try the app, you will certainly struggle with its UI, especially when crafting flows, as I used all my brain juice on the core idea.
I have cool features in my head for a v1 but today I really wanted to simply show what I got.<p>You can access the app directly at <a href="https://gg-charts.com" rel="nofollow">https://gg-charts.com</a> and there are some examples in the Github README to get you started.<p>Happy to answer questions and humbly receive your honest feedback on this crazy idea!

Show HN: Vdm, a sane alternative to e.g. Git submodules
Hey folks! I've been working on something on & (mostly) off for a little over a year, and picked it back up recently because of yet another related frustration at work.<p>I've spent a lot of time ripping out git submodules from repos my teams use, but I've spent an equally large amount of time wondering why there doesn't seem to be a better option for managing arbitrary dependencies across repos in the Year of Our Lord 2024. So, I put together a really early version of such an arbitrary-dependency manager. It's called vdm, and you can find it in the linked URL above & below.<p>I'm sharing mostly because I'm curious if I'm blatantly missing some other tool that exists that <i>isn't</i> language-specific (like Bit for JS seems to be, for example), but also in case people have any hot-takes or feedback on the functionality as listed in the README.<p>Also of note is that I'm not sharing to potentially monetize or "generate customer interest" or anything -- I'm just another builder on the internet.<p>Thanks for looking, and let me know if you have any questions!<p>vdm: <a href="https://github.com/opensourcecorp/vdm">https://github.com/opensourcecorp/vdm</a>

Show HN: Tea-tasting, a Python package for the statistical analysis of A/B tests
I'm excited to introduce tea-tasting, a Python package for the statistical analysis of A/B tests<p>It features Student's t-test, Bootstrap, variance reduction using CUPED, power analysis, and other statistical methods.<p>tea-tasting supports a wide range of data backends, including BigQuery, ClickHouse, PostgreSQL, Snowflake, Spark, and more, all thanks to Ibis.<p>I consider it ready for important tasks and use it for the analysis of switchback experiments in my work.

Show HN: ThinkPost – split-panel note taking & brainstorming app for devs
ThinkPost is an Interactive split-panel diagramming, draggable block-based note-taking, and brainstorming tool.<p>I developed ThinkPost as a side project for few months now.
Basic idea is parallel streaming of ideas. It's a desktop web app with a very scaled down mobile version just for support.<p>Whole my career I had been working with startups and specifically early stage ones, and it's a big responsibility to devise a feature on our own, think deeply about it in different streams (logically, security, re-usability, platform APIs etc.) and even present distilled part of it to stakeholders (Often times non technical people). Even now I run backend/infra/mobile/qa/customer support/integrations for a healthcare startup, so stakes are high. There's a lot of self brainstorming in multiple streams and then there's also distillation process. I couldn't really work with single page notepads for that streaming process. We should be able to note down in split-panels, so there's space for parallel ideas.<p>Many note-taking apps today single-paged have high-think-threshold (windows notepad/apple notes have very low-think-threshold), you have to think before you write in them, so not a good option for quick ideas. So built a platform specifically for everyone who can parallel stream ideas in split panels Textually (low-think-threshold), write as they like), Diagrammatically, Code-wise or even Quick Maths. And also move the idea blocks across panels or within! or Open a new tab if you want more!<p>I'm personally a massive user of my app because I plan everything at my current job via this app, run meetings, self-brainstorm features, study requirements, visualize code-ideas, an develop this when I get time as well.
