Products that do what Sankofa – Chat with the Browser History does
Hey Hackernews, I'm Ofer, head of developer relations at Vectara. Some of us read a lot of articles on the web, like those on HN, and it seems useful to be able to search the contents of the text we read (using semantic search), or ask questions about it (ChatGPT style). Sankofa is a new browser extension that allows you to index web pages you visit and search / ask questions about that content. We built it using Vectara's retrieval-augmented-generation (RAG) platform and hope this is useful to folks. This is an initial release - we would love to hear any feedback and suggestions. BTW,…

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…

Hey HN, As a heavy ChatGPT user, I often want to explore my chat history, look for things I've already asked, keep favorite chats, and much more. ChatGPT doesn't even offer search capability (except in mobile version). So I decided to build one myself. It runs locally, so no sensitive data leaks. You only need to export your ChatGPT conversations, and put it in the `data` folder. Optionally setup OpenAI API key and it will create embeddings for semantic search. *Important* - it's not a desktop app (at least, not yet) - it's a python code with a browser interface that I've only tested on…

TLDR: Check out our documentation search here: https://xata.io/docs/overview Hello HN. I'm a designer over at Xata. We build a serverless database platform on top of Postgres and Elastic-like search that provides goodies like a native TypeScript client for type support in your IDE. Long story short, we're trying to bundle all the normal stuff you need out of a database along with branching, so you don't have to glue everything together. Today we added a new /ask/ endpoint to our search product that bundles in ChatGPT support into any stored data. Why would you…

We’re George and Ann, and want to share a Hacker News specific browser extension that we have been working on. We all love the rich discussions in HN, but navigating long posts with multiple threads can sometimes be challenging. You get lost in the depth and breadth of the discussion. There are a few AI-based summarization tools, but they typically focus on summarizing the article rather than the comments, and thus miss the essence of threaded discussions. So, we built Hacker News Companion, a browser extension that makes it easy to navigate discussions and understand diverse viewpoints…

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…

I built Sutra, a Chrome extension that helps you perform intelligent searches and analyses on your own browsing history. Instead of scrolling through a long list of URLs, you can ask questions like: “What are the clothing-related sites I’ve visited?” “What news related to Gaza have I read?” “What do I usually browse late at night?” “Which links do I visit most often?” “What did I open around the time I was on Etsy yesterday?” Sutra turns your browsing history into something you can actually explore, understand, and reflect on. These analyses can be done either through natural language…

Hey! Alexis and Tobi here. We built a native macOS client for ChatGPT API that is free to use (macOS Ventura). https://www.jamgpt.app/ We built and fine-tuned it to scratch our own specific text-processing itches, so we just wanted to share this with the community. If you work with a lot of text or code like we do, check it out. Its core features include: - Instantly talk to ChatGPT from anywhere on your Mac by pressing a keyboard shortcut. - Avoid typing out repetitive prompts by saving prompts and accessing them quickly. - Just download and start typing as you would with…

I kept running into this annoying problem: I’d remember a really useful answer, but not where it was. ChatGPT? Claude? Gemini? No idea. So I’d end up digging through all of them or just rewriting the prompt. Built this to fix that. It’s a Chrome extension that indexes chats locally and lets you search across them all in one place. Once it’s indexed, search is basically instant. Still early. UIs change and break things sometimes, so it’s a bit fragile in places. Curious if other people have the same issue or if it’s just me jumping between tools too much.

Was getting annoyed copy-pasting stuff from websites into ChatGPT all the time, basically wished Cursor's CMD+K worked everywhere. So I built a little Chrome extension, InPageAI, that tries to do just that: https://inpageai.com Hit a shortcut on any page, it grabs the context automatically, and you can ask AI to summarize, explain, etc. You can also use it to write directly into input fields/text boxes. It's pretty early days, but give it a try? Would love to hear what you think, or if you find places it breaks!

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…

I’m Pranav, co-founder of Chatwoot (https://github.com/chatwoot/chatwoot), an open-source alternative to Intercom and Zendesk. What started as a passion project in 2019, gained a lot of momentum recently. This was possible because of all the contributions and love we got from the community. We’ve created a page (https://contributors.chatwoot.com) to showcase our contributors’ work and give them a platform to share their contributions with the world. We open-sourced this little project too. We’ve made our repo for other open-source projects to use it as a…

Hello! I built this to solve a personal problem of where I didn't want to wade down large chains of HackerNews comment threads in order to get the key takeaways from the discussions. I built this Chrome extension, which supports both OpenAI and Ollama(local LLMs) to summarize comments and display the summary within Chrome's sidepanel. It's open source as you can see from the link, feedback appreciated!

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.

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…

Built QueryWeaver, an open-source text2SQL tool that uses a graph to create a semantic layer on top of your existing databases. When you ask "show me customers who bought product X in a certain ‘REGION’ over the last Y period of time," it knows which tables to join and how. When you follow up with "just the ones from Europe," it remembers what you were talking about. Instead of feeding the model a list of tables and columns, we feed it a graph that understands what a customer is, how it connects to orders, which products belong to a campaign, and what "active user" actually means in your…

SURF (Search Utility & Reading Framework) is an open-source API that bridges LLMs with the web. It provides a standardized interface for web search and content processing that preserves formatting of tables, code, and complex layouts. Key features: - Multiple search providers (SearXNG, DuckDuckGo, Brave) - HTML cleaning and smart content extraction - Model Context Protocol (MCP) integration for Claude and other AI assistants - Self-deployable with minimal setup (Docker, bare metal, cloud) - API key authentication I built this to make it easier to add web capabilities to LLM applications…

So I've been obsessed with a weird question for the past 6 months, what happens to SEO when everyone starts asking ChatGPT for recommendations instead of Googling? The answer, apparently, is chaos. And maybe opportunity? I built FirstClick because I noticed something strange. My previous startup was getting zero traffic from AI assistants, but our competitor (objectively worse product, sorry not sorry) was getting mentioned by Claude and Perplexity constantly. It drove me crazy. So I reverse engineered why. Turns out there's a whole new game being played and most founders don't even know it…

Hey Guys, I created GithubReader.org (open-source, non-profit, most of the code is written by ChatGPT). My motivation: I wanted an easy way to keep a list of repositories I want to learn from and access them quickly. So, I built a search page where I can find repositories by name, like Google. Also, I wanted a nicer way to read Markdown files on my laptop without the GitHub UI, like reading a book. So, I made a custom UI with a back button that takes you to the previous state without jumping pages. The markdown links are sharable, e.g.…
