OSIRT

OSIRT is a completely free application for Windows 7, 8, 8.1 and 10 that has been designed to aid law enforcement officials to perform open source research on the web.

OSIRT provides built in tools for screenshots, video captures and complete webpage downloads including on the dark web. Preview screenshots and videos and document them as you go; they are automatically timestamped, hashed and logged in your case file. Once you've finished your case, select the artefacts you want in the report and export it as either PDF, HTML, XML or CSV.
