1. Show HN: I made a website to semantically search ArXiv papers
URL: https://papermatch.mitanshu.tech/
Author: Quizzical4230
Description: As a grad student (and an ADHDer), I had trouble doing literature review systematically. To combat this, I made a website that finds similar papers using the meaning of the thing I am looking for.
I used MixedBread's [^1] embedding model to generate vectors from the abstracts. I store and search similar vectors using Milvus [^2] and finally use Gradio [^3] to serve the frontend. I update the vector database weekly by pulling the metadata dataset from Kaggle [^4].
To speed up the search process on my free oracle instance, I binarise the embeddings and use Hamming distance as a metric.
I would love your feedback on the site :) Happy Holidays!

2. Show HN: Map of YC Startups
URL: https://yc-map.vercel.app/
Author: yoouareperfect
Description: Hey Everybody! Hope you had a merry christmas
Today I had a bit of fun with Claude.
Started by scraping YC's startups list, then ran them through OpenAI's embedding service, then UMAP'd the embedding to reduce the dimension to just two coordinates and then just forced Claude to write React that would compile to visualize that.
I had fun and I think it's interesting, so take a look!
Also note that you won't be able to zoom on mobile (found about this Plotly limitation way too late). If there's interest I can fix this issue by changing plotting libs tomorrow :)
Merry christmas

3. Show HN: SMS Reminders for Birthdays
URL: https://www.birthdaytexts.com/
Author: mperu
Description: I built a simple service that sends SMS reminders for birthdays.
Why? I kept missing birthdays, even with calendar apps. This single-purpose tool is simple and (so far) reliable. Since my texting inbox has a far better signal-to-noise ratio than email or calendar events, it ensures I never miss an important date. Facebook used to serve the same purpose, but it's a dying social graph for me.

4. Show HN: Explore how nations talk about each other in UN speeches
URL: https://un-speeches.koenvangilst.nl/
Author: vnglst
Description: How it works: Select a country on the globe to explore diplomatic relationships and see who's saying what about whom in the 2024 UN General Assembly Speeches.
How it's made: The project relies heavily on GenAI for several tasks:
- Reading speech documents in multiple languages
- Identifying both direct and indirect mentions of other countries
- Extracting and translating relevant quotations that demonstrate positive or negative sentiment
- Mapping mentions to correct ISO country codes
- Visualization is rendered using d3.js
This is still a work in progress with room for expansion. While currently focused on 2024 speeches, future plans include:
- Analyzing mentions across different years to reveal evolving diplomatic patterns
- Mapping speeches to UN Sustainable Development Goals (SDGs) to show which nations prioritize specific global challenges
Looking forward to your feedback on this initial version!

13. Show HN: I built an AI-powered website builder–no code required
URL: https://www.aiwebsitebuilder.tech/
Author: bilalmoten26
Description: Hi HN,
I’ve been working on an AI-powered website builder that allows anyone to create a fully functional website in just a few minutes. No coding, no design skills—just a simple, intuitive process with AI handling the heavy lifting.
Here’s what you can do with it: • Create a website by entering a name, description, and subdomain. • Use AI to design the site, customize content, and edit sections with simple prompts. • Preview, tweak, and publish your website live instantly. • Download the code for full flexibility if you want to self-host or integrate.
It’s still an MVP, and I’ve got lots of features planned (blogs, eCommerce, themes, and more), but I’d love your feedback at this stage.

URL: https://news-voyager.com/
Author: rausch_
Description: I find it challenging to stay up-to-date with the latest tech news, especially with the overwhelming amount of content out there. News feeds and social media algorithms often prioritize grabbing your attention rather than showing you what's actually relevant.
So, here's my early version of News Voyager—a text-only RSS feed explorer. You can customize the topics that interest you most, and your feed will display the latest articles from those topics.
I'm currently working on a feature that will let you define your own topics. Until then, let me know if there are specific news topics you're interested in or if I’ve missed any relevant news providers.
Happy Shipmas to all of you!

17. Show HN: I made a menu bar app that makes posting on social media less painful
Author: stewones
Description: Hey HN! I built Statuz, a tiny menu bar app that lets you post to Twitter/X and BlueSky without switching between tabs or apps.
I got tired of:
- Having 10 browser tabs open just to post something
- Losing drafts when my browser crashes
- The anxiety of checking character limits
- Uploading the same media multiple times
So I built something that just sits in your menu bar and handles all of that. You can:
- Write posts and threads (up to 15 posts)
- Drag & drop your photos and videos
- Post to multiple platforms at once
- Preview everything before posting
It's a native macOS app (14+), so it's fast and feels right at home. No web wrapper, no Electron - just native Swift goodness.
I'm a solo dev and this is my first major macOS app. Would love to hear your thoughts and feedback!

18. Show HN: Handwritten Christmas Card for Hacker News
URL: https://handwritten-card.vercel.app/show-hn
Author: muc-martin
Description: Hi HN,
I’ve been working on a small project that transforms handwritten notes into animated, shareable cards. While the create functionality isn’t live yet, I wanted to share a sneak peek by creating a handwritten Christmas card specifically for the HN community.
I started thinking about this after seeing too many AI-generated cards, cookie-cutter email templates, and overly polished designs that lack any personal touch. A friend recently sent me a handwritten card in the mail, and it stood out—simple, personal, and meaningful. I wanted to capture that same feeling without the overhead of physical mail. This tool is my attempt to combine the charm of handwritten notes with the ease of sharing a link online.

19. Show HN: We build drones that pick items in e-commerce fulfillment centers
URL: https://www.youtube.com/watch?v=7pFAwioH6Es
Author: DRJDT
Description: At Hummingbird Systems, we have developed a unique drone based approach to robotic warehouse unit order picking, especially well suited to direct-to-consumer e-commerce fulfillment.
So why use drones? … Fundamentally lower cost.
Hummingbird's drone platform is inherently less expensive than ground robots with pick arms or large gantry style AS/RS systems. The drones allow us to directly position the manipulator on task without all the weight and expense of multi-axis backlash free geared motor assemblies.
Furthermore unlocking the often unused vertical real-estate in e-comm warehouses, the ability to leverage existing bins and racking, and a unique overhead tether power system that eliminates the need for batteries or recharging all contribute to the best ROI of any robotic picking solution on the market.

21. Show HN: DIY video magnifier for people with low vision
URL: #
Author: ctrlw
Description: Hi, happy to share this simple video magnifier built from a Raspberry Pi and camera: https://github.com/ctrlw/magni
It captures anything under the camera and displays it on a connected HDMI screen. It can be controlled with push buttons, the buttons of a mouse or a (numeric) keyboard to iterate through a few predefined magnification levels, but can also switch colour mode (colour inversion and others) or read out text via TTS while staying completely on device.
I originally started this for my grandmother who had Macular Degeneration, to give her a second device beside her commercial video magnifier (which costs a few 1000s), and have been updating it regularly over the years. The code is python and the hardware setup is mostly up to you, although I provide a few examples from simply sticking the device to a desk lamp or monitor, up to a nice portable 3d printed design.
If you build it, please let me know any feedback or improvements. Happy holidays!

Description: This is a silly little game I built over the last couple of days.
You launch Santa into the air, then use your arrow keys to glide him to houses to deliver the presents.
I've been playing with React Three Fiber all year, but this is my first game and the first time using the physics engine Rapier. I had a blast, and surprisingly everything turned out pretty much as I envisioned it, from the game loop to the glide mechanic.
There is so much jank and it's desktop browsers only (sorry phone users), but I think it's pretty fun.
Enjoy!

33. Show HN: Llama Run Differs from LM Studio and Ollama(Even Though It Uses That)
URL: #
Author: KrishBaidya
Description: Hey HN,
So, I've been working on an app called Llama Run, which does require Ollama to run its AI models at the moment. I'd like to say what makes it different from tools like LM Studio, or even Ollama itself.
What’s Different?
1. Custom Python Plugin Support (Coming Soon!): I’m working on adding Python plugin support, which lets users create their own scripts to automate tasks. This feature isn’t in LM Studio or Ollama. It’s a big deal if you want to expand functionality beyond just text generation—think automating system tasks, interacting with APIs, or building custom workflows using Python.
2. Assistant-Like Functionality: Llama Run isn’t just about running a model and generating text. The app is designed to act more like a PC assistant. The goal is to let it handle small tasks for you, like adjusting settings or running commands based on AI suggestions, making it more of an interactive utility.
3. Event-Driven System: Plugins will be able to respond to specific events in real time, like button clicks or system changes. This gives users more control over how the AI and plugins interact with their PC. It’s not just about text generation—it’s about creating a smarter PC workflow
4. Designed for Automation: Unlike LM Studio, which focuses more on the models themselves, Llama Run is meant for day-to-day automation. It’s a lightweight app that’ll be able to handle everything from quick tasks to more complex workflows, all powered by AI and Python.
Why I Still Use Ollama Yes, Llama Run needs Ollama at this moment. I'm using their models since it's easier to download and start running locally. But the plan is to make Llama Run more flexible to allow people to use other models or even add their own custom tools via plugins.
I'm curious what you think about these differences:
Does plugin support interest you for AI apps? Have you used LM Studio or Ollama, and what features do you feel are missing in AI tools? You can already find Llama Run in the Microsoft Store if you want to check it out [https://apps.microsoft.com/store/detail/9NW950ZX02CQ?cid=Dev...] (plugin support is in development). I'd love to hear your thoughts!

34. Show HN: Daily Scrums for Side-Projects
URL: https://publicstandups.com
Author: jeffisabelle
Description: Hello HN, and Merry Christmas!
Two months ago, after an acquisition, I was laid off from my job. During my garden leave, I decided to use the time to build something for tracking my side-projects.
At my previous company, we used Geekbot for async daily standups on Slack, which helped me stay focused and motivated each day. Inspired by that, I created PublicStandups — a tool to keep myself motivated on my side projects by tracking daily progress publicly.
Currently you can;
- Create multiple projects and post daily updates.
- Share your updates publicly to build accountability.
- Track daily streaks and showcase your project's progress with a dedicated page.
- Highlight your project's tech stack for others to see.
- Get feedback from other users on your project.
https://publicstandups.com/u/muhammet/p/publicstandups/
Right now, this is a basic CRUD app with no magic at all—but my goal is to evolve it into a robust motivational tool for creators. While it's still early days (some buttons might not work, and some text might need tweaking), it's already usable!
ps; For anyone who signs up during this early stage automatically gets a "Founder" flag. If the project eventually includes premium features, flagged users will get lifetime premium access.
Would love your feedback, suggestions, or ideas to improve it. Let me know what you think -

37. Show HN: Event Scheduling for Groups
Author: gioazzi
Description: A while ago a friend asked for a way to replace pen and paper to track who’s attending lunch at their co-living community; people come and go and they regularly go from 10 to 50 people, with guests occasionally joining. Initially I suggested a shared Google Sheet or Calendar, but as neither didn’t really work for them, I thought it’d be easy enough to make an app just for them, in the spirit of this article that made the front page a while back[^1]. It took a couple of weeks, was nearly free to host on Firebase, and they just loved it and kept using it daily for 2 years, with just the occasional fix from me.
At some point though, some of them started asking about using it for other groups and to manage more events. That app was really not designed with that in mind, I didn’t even think about a multi tenancy of any sorts!
So I took all the learnings from what was now the MVP, and with some friends we now launched this new version, built on Flutter and Supabase.
Hopefully more people will find it useful! I have some ideas to extend it with CalDAV and Calendar integration for “power users”; but with the idea of keeping things clean and simple for most users.
