AnnexVTT — Annex is where the case lives A real-time investigation board for mystery tables. Pin the evidence. Trace the threads. Use Annex alongside whatever runs your combat — this is the room where the case lives. Annex is a free, browser-based virtual tabletop for investigation-driven TTRPGs — Call of Cthulhu, Delta Green, Vaesen, World of Darkness, and kin. It is a supplement to grid VTTs like Roll20, Foundry, and Owlbear Rodeo, not a replacement: combat and dice stay where they are, Annex holds the case file, the witness board, the timeline, the conspiracy wall.
