"The name is quite odd, but it works" - User Review
ButtScribe is a web application that runs off of BattleScribe output, and generates printable datasheets for the units in your army. It currently supports Warhammer 40k (8th Edition) and Kill-Team. The goal with ButtScribe was to bridge the gap in printed materials: the codices have nicely-formatted unit entries, but these are intended for selecting a unit's options, so it has a raft of information that might not be relevant depending on what options you took, and they don't include the actual points/PL costs of your specific unit. That is, the codex will have all of the wargear and rules for a Tactical Squad, but what you really want during a game is the wargear and rules for your Tactical squads, which is where ButtScribe comes in.
Also, BattleScribe does, obviously, support printing army lists, as anyone who has ever played 40k can tell you. The problem is that those lists look like butt.
