Pinbot – An extension to privately search one's browser history with AI
Hello HN, I’m Kamil. The past months have been filled with news about ChatGPT, Bard, etc. Thankfully, there are some heroic attempts to bring that power to the users. I wanted to contribute to that effort with my side project, an extension for Chrome: it makes searching the history by meaning – instead of the exact words – possible. This is only a proof of concept, building on the excellent transformers.js[0], and running entirely in the browser. My goal here is to explore the possibilities unlocked by a client-side AI. I would love to have your feedback, to know which direction that project…
Pinbot – An extension to privately search one's browser history with AI launched on May 17, 2023 with 98 votes, #543 of 4,910 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 3 years on.
In plain words
Pinbot is a Chrome extension that lets users search their browser history by meaning rather than exact keywords, using AI that runs entirely in the browser. Built as a proof of concept with transformers.js, it enables semantic search of past browsing activity without sending data to external servers. The extension is designed for people who want to rediscover previously visited pages but remember only the topic or context rather than specific search terms.

Sourcebot, an open-source Sourcegraph alternative2024 · github.com · ▲259Hi HN, We’re Brendan and Michael, the creators of Sourcebot (https://github.com/sourcebot-dev/sourcebot). Sourcebot is an open-source code search tool that allows you to quickly search across many large codebases. Check out our demo video here: https://youtu.be/mrIFYSB_1F4, or try it for yourself on our demo site here: https://demo.sourcebot.dev While at prior roles, we’ve both felt the pain of searching across hundreds of multi-million line codebases. Using local tools like grep were ill-suited since you often only had a handful of codebases…
Browserfly2025 · browserfly.app · ▲203Hey Hackers! I've had this idea stuck in my head for a while: what if an AI could actually use my browser for me? I mean, not on some virtual machine in the cloud like ChatGPT agent, but right on my own browser. I finally decided to just build it and see what would happen. I wrote a quick MVP, and honestly, I didn't expect much. But then... it started doing things. On its own. It figured out how to use search engine to find what I needed, read a webpage to answer my questions, and even it can organize my chaotic mess of tabs into neat groups. It was a genuine "whoa" moment for me. That's…
- WSWeb search using a ChatGPT-like model that can cite its sources2022 · beta.sayhello.so · ▲318
We’ve trained a generative AI model to browse the web and answer questions/retrieve code snippets directly. Unlike ChatGPT, it has access to primary sources and is able to cite them when you hover over an answer (click on the text to go to the source being cited). We also show regular Bing results side-by-side with our AI answer. The model is an 11-billion parameter T5-derivative that has been fine-tuned on feedback given on hundreds of thousands of searches done (anonymously) on our platform. Giving the model web access lessens its burden to need to store a snapshot of human knowledge…

A web browser agent in your Chrome side panel2025 · github.com · ▲153Hey HN, I'm excited to share BrowserBee, a privacy-first AI assistant in your browser that allows you to run and automate tasks using your LLM of choice (currently supports Anthropic, OpenAI, Gemini, and Ollama). Short demo here: https://github.com/user-attachments/assets/209c7042-6d54-4fc... Inspired by projects like Browser Use and Playwright MCP, its main advantage is the browser extension form factor which makes it more convenient for day to day use, especially for less technical users. Its also a bit less cumbersome to use on websites that require you to be…
Pigeon2025 · chromewebstore.google.com · ▲99Hey HN, My friend and I built a Chrome extension called Pigeon because we kept Googling “Reddit + [product name]” whenever we wanted to know what real people thought about something. Pigeon saves that step by looking at what’s on the page, finding related Reddit discussions, and showing the most helpful comments and opinions in one place. We’ve both found it super useful when researching products or topics online and thought others might too. Check it out and let me know what you think!
