File Reader

File Reader lets Casper open supported uploaded documents, extract their readable content, and use that content directly inside the conversation. It supports common document and data formats and can fall back to OCR when a PDF contains little or no extractable text. It can: Read TXT files Read PHP source files Read CSV files Extract text from PDF documents Use OCR for scanned or image-only PDFs Read DOCX documents Read XLSX spreadsheets Extract usable text and table-style data Bring the extracted content into the current conversation Let Casper answer questions, summarise, explain or work from the uploaded file Temporarily retain the extracted file context for the active session The current implementation supports files up to 15 MB, with extracted content capped before being injected into the conversation context.
