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…

Perplexity Labs▲638We built a search engine interface on top of OpenAI GPT 3.5 and Microsoft Bing that summarizes and cites top search results in response to natural language questions. By using search results, the AI is able to reference recent news and provide citations for specific facts. Our interface offers concise answers, without having to click through links, scroll past irrelevant content, or read ads. No login is required; no personal data is collected. We believe in the power of combining the intuitive UI of web search with the intelligence of large language models. The search engine does indexing…

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. It takes away the pain of crawling, extracting content, chunking, vectorizing, and updating periodically. 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...

I've built an advanced RAG (Retrieval-Augmented Generation) pipeline from scratch to demystify the complex mechanics of modern LLM-powered Question Answering systems. This repository features: -- An implementation of a sub-question query engine from scratch to answer complex user questions. -- Illustrative explanations that unveil the inner workings of the system. -- An analysis of the challenges I faced while working with the system, like prompt engineering and cost estimation. -- Qualitative comparison with similar frameworks like LlamaIndex, offering a broader perspective. Key Takeaway:…

AEO Tool▲5Hi HN, Over the last months, I noticed something odd: many websites that rank well on Google simply don’t appear when you ask ChatGPT, Gemini, or Perplexity for recommendations or explanations. At first I assumed it was just noise. But after testing dozens of sites, a pattern started to emerge: AI systems don’t reward “SEO-optimized” pages — they pick sources that are clear, structured, and easy to reuse as answers. SEO tools don’t really explain this. Manual prompt testing is inconsistent. And most advice around “AEO” is still vague or theoretical. So I built a small tool to experiment with…

Hi HN, I’m launching betterAEO, a tool we’ve been building to help websites understand and improve how they appear in AI-generated answers from tools like ChatGPT, Google AI Overviews, Perplexity, and Claude. The motivation came from noticing that traditional SEO metrics don’t capture how AI engines select and summarize content. Sites with strong SEO can still be invisible in AI summaries, meaning users get answers that favor competitors even when your content is high quality. betterAEO lets you: - Measure your site’s AI-readiness with a single AEO Score - Identify gaps in schema, snippets,…

Codebased combines Tree Sitter for code awareness (find functions, data structures, constants, etc. not just lines of code), full-text search using SQLite, and semantic search using OpenAI embeddings + FAISS. Despite being implemented in Python, supporting semantic search, making multiple API calls for embedding and re-ranking, it is faster than ripgrep for runng searches against the Linux kernel (takes ~1 second vs. ~2 seconds, obviously depends on system, temperature, time of day, tidal forces, etc.) Up next: - A Perplexity-like agent for interpreting results, making multiple follow-up…
