A case, not a checklist
RequestLoops centers on a single request per client, without modeling separate people or tasks inside it. Xenqu assigns each party their own items under one case, then tracks the whole thing.
The agent stays on the case after setup
Their AI helps build the request once, at the start. Xena keeps working every open request for the life of the case, adjusting each message to what is still outstanding.
A record of who was asked, and when they answered
Xenqu keeps a timestamped record of every request, reply, and document decision with the case, so the history is there if you need it later.
