Rule Summon

Never stop the game to look up a rule again.

Rule Summon listens at your table and the moment someone says a spell, monster, condition, action, feature, feat, or magic item, its card appears on screen — no typing, no searching, no wake word. Set the phone down and play; the answer is already there by the time anyone reaches for it.

ALL ON YOUR DEVICE, FULLY OFFLINE
Speech recognition runs entirely on your phone. Your table's audio is never recorded, never uploaded, and never leaves the device. No account, no sign-in, and it works with no internet at all — perfect for the deepest dungeon or a basement with bad Wi-Fi.

HOW IT WORKS
• Tap Start and play normally. Spoken rule terms stream into a scrollable, timestamped feed (newest on top).
• Tap any card for the full rules text — including complete monster stat blocks.
• Filter the feed by category (spells, rules, monsters, and more) with a tap.
• It keeps listening with the screen off, so a glance is all you need.

TWO EDITIONS BUILT IN
Switch between D&D 5e (2014) and the 2024 rules in Settings — spells, conditions, actions, class and racial features, feats, skills, monsters with full stat blocks, and magic items, for each edition.

BROWSE ANYTIME
Search the full rule set whenever you like, in or out of a session — completely free.

MADE FOR THE WHOLE TABLE
Whoever speaks the word, everyone gets the answer at the same moment. Built by a DM, for players and DMs alike.

FREE TRIAL, THEN SUBSCRIBE

BRING YOUR OWN RULES (Pro)
Subscribers can import a simple CSV of homebrew spells, items, monsters, or house rules, and Rule Summon recognizes them by voice right alongside the core content — formatted stat blocks and all.
