Research & data toolkit
Turn web pages, files and spreadsheets into clean input, and let an agent write the research report.
MarkItDown converts PDFs and Office files to Markdown. For the web, use Crawl4AI if you want to self-host, or Firecrawl MCP if you want a hosted service. GPT Researcher runs the whole research loop and writes a cited report. The xlsx skill handles the spreadsheet at the end.
