I want to give a ringing endorsement of the Cthulhu Architect Handout site. It's one of the most practical, high-quality, and user-friendly tools available for game masters looking to up their game. Best of all, it's absolutely free.
Over 250 templates are available, the vast majority tailored to classic-era scenarios. The site allows you to generate authentic-looking 1920s documents in minutes, including standbys like telegrams, newspaper clippings, police reports, and handwritten notes. The interface is easy to use and allows you to customize every bit of text with a variety of typography and layout choices. You can even add "bloodstains" or coffee rings for that extra touch of wear. When you're done customizing your document they're easy to export for printing or digital use.
The focus is on period paperwork, but you'll also find a variety of modern templates. That includes contemporary drivers licenses, computer screens, and CCTV overlays. Just the thing if you're running a modern-era Mythos game like Delta Green.
While the site offers a wealth of functionality for free, the premium "Cultist" option provides more storage space, early access to new templates, and direct export to FoundryVTT. It's clear that this site was built by someone who loves the hobby. The interface is clean, the updates are frequent, and it's the perfect tool for game masters running a high-touch, handout heavy game.
