AMBA is where scattered prep becomes a structured adventure — and where publishers ship modules their customers can actually play. Free for authors. Free for buyers who redeem a purchase.

An adventure as connected parts, not just a long document
AMBA treats an adventure as a structured collection of connected parts. Each act, scene, and encounter is a typed object with known relationships — not merely a heading in a document. Maps, handouts, monsters, and GM notes stay attached to the right place in the module tree.
That makes it practical to reorder whole branches, find every encounter in an act, export selected scenes, and prepare player-facing output without exposing GM-only material.
Combat, characters, VTT, and player links — without rebuilding the encounter in every tool
Once an encounter is structured in AMBA, export it in a few clicks. Maps, creatures, tokens, and narrative travel as structured data — so you are not rebuilding stat blocks, placing every token by hand, or copying narrative into separate apps.
Assemble once in AMBA → export to WG and Owlbear → run at the table
AMBA is where the pieces become an adventure. Publishers assemble and ship for free. Customers redeem and play for free — with exports to the tools they already use at the table.
Free for publishers. Free for players.
AMBA is free.
