Lightweight PDF / web page QA bot

Chat with PDF, web page or (new) csv/Excel documents. The default is a small model (Gemma 3 1B (small, fast)), that can only answer specific questions that are answered in the text. It cannot give overall impressions of, or summarise the document. The alternative (Phi 3.5 Mini (larger, slow), if available), can reason a little better, but is much slower (See Advanced settings tab).

By default 'Document redaction app documentation' is loaded.If you want to talk about another document or web page, please select from the second tab. If switching topic, please click the 'Clear chat' button.

Caution: This is a public app. Please ensure that the document you upload is not sensitive is any way as other users may see it! Also, please note that LLM chatbots may give incomplete or incorrect information, so please use with care.
