Your AI investigation agent, on one board.
Connect your own AI assistant, such as ChatGPT or Claude, to Evidence Board and it works on your case as an agent: it researches, saves its sources, builds the board, links the evidence, draws the timeline and reviews what doesn’t add up, citing every card.
Free for 3 cases. No card needed.
