Actually Microsoft's digital collaborative whiteboard might be better than trello, although both are free. The collaborative nature and the ability to attach the documents visually would make it a pretty good fit. Tons of others out there like miro.com, conceptboard.com ryeboard.com that have varying levels of "free" but I think if it's purely word docs you're working with, sticking with the Microsoft universe...

Oh, and to easily convert images to ANSI-like art on a modern system, use a program called Playscii (https://jp.itch.io/playscii). Source: about 3 years ago

I found this cool ASCII art program on Itch.io called Playscii. After faffing about with it for a while I thought some of the character sets would work well for making maps. So I redrew the map of a Sky Tomb from the Stars Without Number adventure Hard Light. They're not spectacular (I'm still new to visual art) but I think they look super cool. I think this visual style fits really well with the OSR. Source: over 3 years ago
