WebCopilot

WebCopilot is a Chrome extension from IndianAppGuy Tech Pvt Ltd that turns a user's own uploaded documents into a searchable knowledge base available while browsing any website. Users upload PDFs, text files, web pages, or Notion documents, then ask questions in natural language and get answers pulled from that material, with citations back to the source document rather than an open-web search. The extension supports semantic search, meaning it matches meaning rather than exact keywords, keeps conversation context across a session, and lets users organize uploads into multiple separate knowledge bases rather than one shared pile of documents. For developers who want the same retrieval behind their own product, WebCopilot exposes a full REST API to embed a knowledge base into a custom application. The tool targets people who need quick recall from a personal document library while working elsewhere in the browser: teams referencing meeting notes and strategy docs, researchers and students working through papers and lecture notes, support staff checking internal help docs and SOPs, and knowledge workers digging through saved bookmarks and articles. A free tier exists alongside a premium plan, though specific premium pricing is not detailed on the public site.
