Loomweaver

Weave your world.

A campaign manager for D&D dungeon masters and players who want more than notes. Build worlds, run combat, manage sessions, make maps, dim the lights, update character sheets, and ask your personalized Oracle for help — all in one tool.

Currently in private alpha. Public launch coming soon.

Everything your campaign needs, in one place.

Stop juggling Notion, Roll20, Discord, D&D Beyond, and three browser tabs of homebrew tools. Loomweaver is your DM workstation and player portal. Prep, run, and enhance your sessions from a single app.

World-building

NPCs, PCs, locations, factions, items, lore, spells, maps, encounters, quests, and more. Hover cards, search across everything with Ctrl+K, share what you want with players, and cross reference everything to plan your sessions.

Live combat tracker

Build encounters in app, then track initiative, HP, spell slots, conditions, rollable actions, damage attribution per PC, and more during combat. Players see a synced view on a second screen or in their own app with concentration prompts, custom backgrounds, and floating damage numbers.

Map Creation

Create overland maps as flat-top hex grids with painted terrain, labels, linked locations, and more. Build square maps for dungeons with linked encounters, notes, labels, icons pulled directly from your npc store, and more.

Lights and Sounds

Wire your Home Assistant lights, music, and a soundboard of effects directly into the app. In combat: Crits flash gold, downed PCs dim the room, your combat screen and lights pulse and flash together. In the world: music and lights automatically adjust to your location adding ambiance and immersion.

The Oracle

An AI assistant that knows your entire world: every NPC, location, item, session, and more. Ask for plot hooks, encounter ideas, to create a new enemy, or a tavern’s drink list. Populate your world with suggestions at the click of a button.

Session recording & recaps

Record live sessions in-browser, transcribe locally (no audio sent to Loomweaver), and let the app generate session notes and recaps automatically.

Player portal

Each player gets their own sign-in to view their character sheet, inventory, spellbook, and party status in a clean read-only interface. Live session data syncs in real time so a tablet at the table can show initiative, HP, conditions, handouts, and quest logs, so the DM can focus on running the session.

Calendar sync

Connect your Google Calendar in one click. Schedule sessions with times and durations, and auto-invite every player whose account is linked to a PC. Reschedules made in Google flow back into Loomweaver automatically — no manual syncing.

Deep customization

Build or import homebrew items, spells, and currencies your players can use natively. Every setting can be overridden per-campaign: which spell and item sources are visible, what currencies you use, XP-based or milestone leveling, traditional spell slots or a customizable spell-point system, and more.

No AI? No problem.

Every AI-powered feature in Loomweaver can be disabled with a single toggle in your settings. The Oracle, image generation, automatic notes, AI suggestions, etc., all turn off cleanly while every other part of the app keeps working at full capacity. No half-functional menus, no nagging upsells. Use as much or as little AI as you want, and “none” is a perfectly good answer.

Build maps as hex grids.

Paint terrain with sized brushes, add labels and notes, link locations, add icons, control what players see with fog of war, and let the app calculate distance and travel time for you.

Run combat without leaving the screen.

Initiative, HP, conditions, rollable actions, attribution. The player view stays in sync on a second monitor or in your players’ app(s).

The Oracle knows all.

More than just a chatbot: the Oracle knows every NPC, location, and session in your campaign and can answer any question you ask. It can also make proposals to create new npcs, encounters, quests, and more at your direction.

Draw dungeons cell by cell.

Place tiles of any size, paint colors, drop symbols and DM notes, and stage tokens for combat. A Move tool lets you shift everything around for convenient editting.
