Search webpages or entered text for the answers you need. If you've ever been to pages like Wikipedia, you know finding simple answers in the vast amounts of text can be a pain. Semantic Search makes finding answers easy and painless. This extension gathers the text from your current webpage, takes a question as input, and passes both to ChatGPT to generate a response.
How to use: Navigate to any website that you need answers from, input your question, and hit enter. It only takes seconds to get an answer from even the largest webpages. Additionally, a confidence score is provided, so you know how well you can trust the result.
