Show HN: Spark KNE Verify – Verify selected AI claims in the browser

- **Spark KNE Verify** is a Chrome extension that lets users highlight a claim made by an AI (e.g., a chatbot output) and instantly check its factual accuracy against a knowledge base, without leaving the browser page. - **KNE** likely stands for "Knowledge Network Embedding" or a similar knowledge-graph / retrieval-augmented generation (RAG) approach — the extension presumably queries structured facts or trusted sources behind the scenes. - This tool addresses a growing practical problem: large language models (LLMs) like ChatGPT, Gemini, and Claude can produce confident-sounding but false or unsourced statements ("hallucinations"). Users currently have to manually fact-check by opening tabs and searching. - The extension positions itself as a lightweight, in-browser verification layer for AI outputs, competing with similar fact-checking tools (e.g., Chequeado's Verificador, or browser plugins for claim matching). It was posted on Hacker News ("Show HN"), indicating it is a new, self-made project seeking feedback.
