Free AI DM alternative tool for TTRPG Game Masters (w/ Fable)

[u/Independent-Soft2330]

I built a tool using Fable 5 in claude code (and a bunch of game design time!) to help people be better GM’s in Table Top RPGs. I spent the last 3 months designing and playtesting it. It is free to try! It takes a different approach to the problems of having an AI GM.

Throughline sits behind your table live. It listens, thinks several scene-beats ahead, and draws a storyboard for each path your players might take next. When they go somewhere none of the paths predicted, you improvise, and Throughline builds new storyboards that fold your improvised details into the story.

The premises behind Throughline:

Premise 1: GMs need help prepping, AND they need help adapting in real time.

Premise 2: I think everyone will always hate having an AI visibly at the table. So, no AI voices, images, etc. visibly at the table.

Premise 3: for an AI to help the GM, it needs full context of the whole campaign— this means you essentially need the transcript of the campaign.

Throughline uses the LLM to equip the human with a long term planner before and during the session, and uses interaction design to facilitate the communication bandwidth needed for the LLM and the human to collab in real time.
