Sign in with your BGG account and your entire game library loads instantly. Over 140,000 board games tracked — if you play it, it's on BGG.
Built for serious hobbyists who want the right answer, not a guess.
Connect your BoardGameGeek account and your entire owned game library appears in the sidebar — thumbnails, ratings, and all.
Upload the rulebook PDF directly from the BGG files page. We extract every page of text so nothing gets missed.
Ask natural language questions. Get answers pulled verbatim from the rulebook, with page numbers cited so you can verify yourself.
The AI never guesses or uses outside knowledge. If the answer isn't in your rulebook, it says "I cannot find that in the rules."
Upload official FAQ or Errata documents alongside the base rulebook. Errata answers automatically override conflicting base rules.
Every answer references the exact page it came from — "According to page 14…" — so you can point to the book and end the debate.
TTRPG corebooks are notoriously dense — action economy edge cases, concentration rules, grapple interactions, lore buried three hundred pages in. Upload any D&D, Pathfinder, Call of Cthulhu, or other RPG PDF and get instant, page-cited answers without pausing your session to hunt through indices.
