The desktop workstation for game masters

Campaign intelligence for tabletop RPGs.

Canonex keeps your whole campaign — people, places, factions, secrets, sessions and fights — in one connected workspace, so you can plan the next session, run it without losing focus, and remember everything that happened.

How it works

Plan , then Run , then Remember

A virtual tabletop runs the game world. Canonex runs the GM’s side: what you prepared, what you need right now, and what the campaign has become.

  1. Plan

    Build the session from your campaign.

    Outline the night in beats, then drag in the NPCs, locations, encounters, maps and read-alouds it needs. What you didn’t reach last time carries forward.

    A session plan with numbered beats holding NPCs, places and encounters, the party, and the Codex beside it.
  2. Run

    Keep your eyes on the table.

    Summon any record with a keystroke and arrange it on the desk. Related records show their ties. Jot notes, pull a DC or a name, and follow the fight in Foundry, without breaking the scene.

    The session desk: cards for two NPCs and a tavern, the night’s two encounters ready to start, and a GM note.
  3. Remember

    Let the campaign keep its own history.

    Wrap up what actually happened and make it canon. Canonex tracks every change, who knows what, how each NPC feels about the party, and the threads you left open. Between sessions, the world turn moves the factions on.

    The campaign Home: the session under way, Campaign memory’s open threads between NPCs, the party roster and the prepared encounters.

What’s inside

One campaign, every angle

Connected tools that share one model of your campaign, so nothing needs entering twice.

  • Codex

    Every record, kept like a dossier

    NPCs, creatures, locations, factions, shops, deities, facts, quests and journals, each on a sheet shaped for the job it does at the table.

  • Relationships

    A campaign that knows how it connects

    Ties between records carry a kind, a direction and a secrecy level. The Campaign Graph shows the whole web, and you can build it right there by dragging one record onto another.

  • The Desk

    A GM screen that arranges itself around you

    A zoomable workspace where records become cards you summon, arrange, pin and dismiss, so what you need tonight stays within reach.

  • Sessions

    Plan the night, run it, carry it forward

    Build a session outline from beats and campaign material, run it from a live cockpit, then wrap up what actually happened.

  • Game systems

    Pathfinder 2e and 5E, ready out of the box

    Choose a system for each campaign and everything follows it: sheets, DCs, encounter maths, the creature builder, treasure, names and the rules lookup. The rules content comes with the app, so there is nothing to install first.

  • Encounters

    Encounters built from your campaign

    Drag creatures, NPCs, places and treasure onto an encounter. Canonex works out the threat for your party in your system and keeps each participant separate.

  • Continuity

    Campaign memory that keeps up

    Canonex records what changed and when, who knows what, and how each NPC feels about the party, and shows the threads you left open and the prep you never used.

  • The world turn

    The world keeps moving between sessions

    Say how much time passes and who acts. Canonex writes a briefing from everything your campaign has recorded; paste it into the AI chat of your choice, paste the answer back, and Canonex files what happened.

Early — being refined

Canonex prepares, runs and remembers. Foundry stays the tabletop.

  • Follow combats started in Foundry, with live hit points, AC and conditions
  • Live sync only while you choose it, so the relay is not polled all evening
  • Connects through the Foundry REST API module and relay
  • Your files, on your disk

    Each campaign is a folder of readable files. No account or subscription, and no cloud lock-in.

  • A GM instrument, not a VTT

    Maps, tokens and dice stay in your virtual tabletop. Canonex handles what you need to know.

  • Your system, or your own

    Pathfinder 2e and 5E come ready to play, rules content included. Everything that doesn’t need rules works for any game.
