    I found myself jumping between ChatGPT, tabs, and docs, but never building real understanding. This is my attempt at fixing that — for researchers, curious readers, and lifelong learners. Would love your thoughts on the interface, and whether this would be useful in your own work or otherwise.

    Just finished the first draft of my weekend project. Sadly my industry is far away from all the exciting machine learning developments happening right now, so I wrote this project as my first exploration into the world of LLMs. It's not perfect, but I'm excited to see where the project goes from here! https://github.com/clarkmcc/chitchat My main motivations were: - Easy-of-use: Many models are supported out-of-the-box so users don't have to figure out how to download, where to save, etc. - Intuitive: A clean interface - Cross platform: The project is written in Rust and…

    Hey everyone, ChatGPT recently added a very small but powerful feature - the ability to share your chats! I think it’s a great way to create prototypes and share them, here are a couple of examples: First, [a small talk simulator](https://chat.openai.com/share/1329d8ec-5141-45f9-a2c2-842d4bad7bcc) a game to help you improve your social skills. Second, [a shark tank simulator](https://chat.openai.com/share/48155efe-101b-4662-b41e-c13aa909f017), see if your idea and pitch can get a deal on ABCs hit show! [Here’s my…

    A simple chrome extension that lets you chat with any webpage using AI. I was tired of copy pasting into Chat GPT from webpages all them time so built this. Popular Use Cases: 1. Summarize Articles – Get concise overviews of content from sources like HackerNews, Reddit, and more. 2. Quick Information Lookup – Effortlessly locate key details on pages such as developer documentation, car forums, and beyond. 3. Personalized LinkedIn Outreach – Craft customized outreach messages for your LinkedIn connections with ease. 4. Review Analysis – Analyze feedback and reviews from platforms like Airbnb,…

    I recently received access to develop and use ChatGPT plugins, and embarked on a project to build a Hacker News integration as a learning exercise. My goal was to enable retrieval of content from HN to answer questions and produce insights in conversations with ChatGPT. I documented my journey in this blog post, which will hopefully be helpful to other plugin developers or anyone looking to learn more about embeddings. You can try the experience even if you don't have plugin access on ChatGPT through the demo on hn.kix.in - it's a loose approximation but should give you a sense of what's…

    Hey everyone on HN! We recently spent the past couple of weeks building out an end-to-end platform which can plug-in multiple models (both open/closed-source) to create voice driven conversational applications. We've tried to make the process simple & concise through documentation. Feel free to try it out and provide feedback. We will be launching a dashboard in the coming week for monitoring and analytics alongwith more open source models. Let us know what you all think. (if you want to contribute, we have tons of features planned - do let us know)

    Hey everyone! Many of you might have come across the Mamba paper a few days ago, which introduced an LLM based on a state space model architecture. The Mamba architecture is quite useful as its complexity scales subquadratically with input length and is therefore way more efficient than transformer models: https://github.com/state-spaces/mamba I got really excited about the paper, so I decided to fine-tune the model on a chat dataset. It turns that this actually worked quite well! The model is quite suitable for casual chatting, which honestly surprised me given that it…

    Hi HN! I built this bot that allows you to chat with your technical documentation! It’s been pretty nifty so far on our Discord help forums, and it’s open-source so I figured I would share! Cheers.

    The first ever AI peer reviewed research article just got approved. It’s kinda crazy how advanced AI have come to replace researchers. I've just been using Deep Research on ChatGPT and Perplexity a lot to write and research complex technical reports for my boss. He loves the reports and it has decreased my workload a ton but I still have some frustrations with it. None of them provide an API that gets me the same quality of output you would with the applications. I wanted something with more control on the LLMs, swappable with the reasoning new models that came out. Not just prompt →…

    Hey HN, Since the launch of GPTs, I’ve struggled with integrating vast, up-to-date knowledge into a custom GPT and embedding it into websites and apps. After months of trial and error, we’ve developed an AI Search & Knowledge Assistant that solves this problem. Over the weekend, I built a demo assistant for Stripe that provides accurate answers, useful links, images in responses, cites sources, and keeps a thread history of your conversations. Here’s what’s included: - 3,700+ public documents full of useful info - 105+ million characters of rich knowledge - Powered by the ChatGPT-4o model…

    Hey HN, Like many of you, I’ve been using ChatGPT to brainstorm, debug code, and even plan projects. But as the number of conversations grew, I found myself scrolling endlessly trying to find old chats. It was frustrating and unproductive. So, I built PinFold – a Chrome extension to help manage and organize ChatGPT conversations. With PinFold, you can: Pin important chats for quick access. Organize conversations into folders (e.g., personal vs. work-related). Declutter your ChatGPT history and boost productivity. It's privacy-focused: no data is sent to external servers – everything is…

    Hi HN, we're Arnav and Adi, and we're building DataBridge - a multi-modal database built from the ground up with AI use cases in mind. We recently launched support for ColPali-style image embeddings and late-interaction retrieval. We've implemented a hamming distance version of retrieval which helps this approach scale significantly more when compared with the regular late-interaction similarity scoring. These embeddings provide a significantly better retrieval accuracy, with ColQwen achieving around an 89% average score on the ViDoRe benchmark, compared to around 67% for traditional parsing…

    After trying some queries, I found ChatGPT is good at finding public data, sometimes it may not be accurate, but overall, pretty good. Then why don't we make the data in a beautiful way ready to share? Columns + ChatGPT (alpha) is for data researchers! Looking forward to any feedback or suggestion...

    Hey HN, when building ML systems for industrial AI, we have learned that data inspection is critical during the ML development process. We are also big fans of the Hugging Face ecosystem. That is why we built an integration to our data exploration tool Spotlight that allows you to interactively explore Hugging Face datasets with one line of code. Spotlight lets you leverage model results such as predictions and embeddings to gain a deeper understanding in data segments and model failure modes. Currently, many many NLP, CV, Audio and multimodal datasets are supported both locally and on the…

    Hi HN, I built Lengpal, a simple language exchange platform where two people get instantly matched on video to practice their native and target languages. There’s a timer built in so both sides get equal time to speak. I created this because I wanted something beyond passive apps like Duolingo. Something to actually speak with real people without the hassle of scheduling or chat fatigue. Right now we are testing the concept with a waitlist. We’ve collected 77 emails so far from Reddit and IndieHackers. I would love your feedback before launching the MVP. Site:…

    I’ve been using this for my own workflow and friends suggested I share it with them so I quickly threw together my first chrome extension! As an ex-editor, I think chatGPT is overlooked as an editor with everyone jumping straight into writing. Editing is essentially giving it as comprehensive a writing prompt as possible. Playing with the actual prompt also gets you a wide range of different results that grammarly/other apps cant really do. The x% has been changed tool was the first thing I built to see how intrusive chatGPT's editing was at a glance. My biggest struggle was trying to…

    This is far from complete, and I am far from an elisp genius, but this is an Emacs package to help you write code or text or whatever in your favourite operating system slash text editor. It's got a couple of useful functions like inserting at point with local code context, querying about something and putting the output in a temporary buffer, passing the current major mode to ChatGPT, contextual system prompts, and so on. Some small demos in the readme. Some of you may enjoy the deep magic this might unleash, so I'm posting it here. And feel free to add pull requests if you are a better…
