Vol. I · The game-night app for tables that meet in person

Where the table
meets the realm.

Running a game is the hard job at the table — and the reason so many groups never get started. Isometra carries the prep, the maps, the sound and the rules, so you can spend the night on the people in the room.

CHAPTER I

The hardest seat
at the table.

Every group needs someone willing to run the game, and that is the seat nobody volunteers for. It is not the rules that stop people — it is the hours before the session, the notebook nobody else can read, and the question you cannot answer when a player asks who they met three months ago.

Isometra is built to make that seat easier to sit in. The DM Command Center holds the world on the laptop at the head of the table. The Player Companion sits in your players’ pockets. They stay in step, and the story stays in the room.

Chapter II · The night itself

Built for the room you're sitting in.

Most tools for this hobby assume everyone is somewhere else. Isometra assumes the opposite: you are around one table, the snacks are out, and the screen in the corner should be showing the map.

isometra.app/campaign · Cast to the table

The map goes on the TV

Throw a battle map, a location's art, or an NPC portrait onto the screen everyone is already looking at — join by code from any TV browser, or cast in one tap from Chrome. Your secrets stay on your laptop.

The room gets a sound

A three-bus soundboard — music bed, layered ambience, effects — stocked with a properly licensed library. The tavern hushes when the door slams open.

Props you can hand over

Print any NPC, item, location or spell as a cut-guide card, and push handouts to players mid-session. Some things should be paper.

Players join by scanning

Show the code, they scan it, they make a free account, and they are in. Stock the table with prebuilt characters and a player who has never rolled a die can claim one and start playing.

CHAPTER III

A campaign that remembers itself.

NPCs and the favors they owe. Locations and what hides in them. Quests, their threads, who pulled them. Nine sessions in, 'wait, who told us about the tide-charters?' is one search instead of twenty minutes of notebook archaeology — and the Chronicle builds itself from the recaps you already wrote, one entry per session, yours to keep or cut.

CHAPTER IV

The web of your world.

The Atlas draws every NPC, faction, location, quest, and deity as one living graph — who serves whom, what hides where, which thread leads to the next. Click any node to see everything it touches.

CHAPTER V

A map drawn for your world.

The Cartographer holds your setting as one hierarchy — world, region, city, and tactical maps — and pins every NPC, quest, trap, and session onto it. In a hurry? The library ships 72 ready-made gridless battle maps — 60 scenes across twenty environments, plus a dozen blank terrains to drop your own miniatures onto. You can always upload your own.

CHAPTER VI

The party, in pocket.

When your ranger prepares spells in the morning, they reach for their phone. When the rogue checks for traps, they tap their dice tray. The DM's table and the player's pocket share one truth.

Chapter VII · The Loremaster

Prep help that knows your world.

The Loremaster reads your campaign, not the internet. Ask it about the priestess you invented in Session 2 and it remembers her. Ask it for her rival and a new NPC is written into your cast — statted, linked, and yours to edit or undo. It works before the session, so that during the session you can put the laptop down.

It knows your world

Every answer is grounded in your campaign's live state — your NPCs, your quests, your secrets, the session you ran last week. Not generic fantasy. Yours.

It writes real records

Ask for a rival smuggler and one appears in your Cast — statted, storied, linked to the faction you named. NPCs, locations, quests, factions, pantheons and deities; monsters, spells, items, feats and backgrounds; traps, treasure, mounts, familiars, encounters, handouts, random tables and notes — the Loremaster drafts them all, into the same editors you use by hand.

You stay the author

It answers from your campaign's own records, and tells you which ones. It logs everything it does, and the writes you would want back — new records, edited fields, whole imports — revert in one click. Generated art is the exception, managed in its own image history instead. Suggestions wait for your approval; the canon is yours.

Chapter VIII · Worlds by Isometra

Start with a world we built.

Ready-to-run starter campaigns, crafted end to end — every NPC, map, quest, and deity. Fork one and make it your own — it all comes with you, and stays yours.

The reckoning

One subscription, not five.

The usual kit for running a campaign is assembled out of five separate services that do not talk to each other — so the DM becomes the integration layer, copying the same NPC into three of them.

Isometra is all five, in one place, sharing one campaign. Which means the NPC you write once is the NPC on the map, in the session, on the printed card, and in the answer when a player asks who she was.

The Tithe

What it costs to begin.

Players stay free forever — joining a table costs nothing and always will. Dungeon Masters start free and upgrade for more AI and more campaigns. Stop paying and your world stays yours: every campaign you have made stays readable and editable, exactly as you left it.

Marginalia

Questions, asked sideways.

01.
Do my players need accounts?
Yes, a free one — the usual name, email and password, then one confirmation link to click. It never asks for a card and a player account stays free forever. They build their character on their phone before the first session, and join any campaign by link.
02.
Does this replace a virtual tabletop?
No, and it doesn't want to. Virtual tabletops are built for playing remotely. Isometra is for the table you're already sitting at.
03.
Does the AI run the game?
Never. The Loremaster preps, drafts, and remembers — it does not sit in your chair. It writes suggestions into your codex where you approve, edit, or revert them; the dice, the voices, and the rulings stay human.
04.
What about the rules?
The 5e SRD is built in — every spell, item, and monster, in both SRD 5.1 and 5.2.1. For non-SRD content, you can add your own homebrew with full parity: it renders, links, and plays exactly like SRD content.
05.
Can I bring my own world?
Yes. Start blank, sketch the realm, drop pins. Or fork a published world from /discover and customize from there.
06.
What rules editions are supported?
Today: SRD 5.1 and SRD 5.2.1, both included by default. New editions get added as the publishers release them under permissive licenses; homebrew rules can be added per-campaign without waiting on us.
07.
What happens to my campaigns if I stop paying?
Nothing disappears. Plan limits apply when you CREATE something new — they never lock what you have already made. Every campaign, character and map stays readable and editable on the free plan. You can also download the whole campaign as a zip — readable Markdown, a campaign.json with every field, and your images — and turn it into a printed book. We think holding your own work hostage is a bad way to earn a subscription.
08.
Do you use AI art?
You can generate portraits, maps and scene art if you want them, and you can upload your own portraits, entity art, maps and gallery pieces instead — commissioned, drawn, or pulled from your own folder. Nothing is generated unless you ask for it, and the art is never the point: the point is the campaign underneath it.
09.
Can I bring in notes I already have?
Yes. Paste them, or photograph a page of your notebook and Isometra will read it into real records you approve before anything is saved.
HOW TO BEGIN

Three steps to the first roll.

I
Start the campaign

Name the realm. Bring your own world, fork one from Discover, or start from a blank page.

II
Sit down together

Show the join code. Your players scan it and pick a character — prebuilt ones are ready if nobody has made one.

III
Run the first session

Map on the TV, sound in the room. You bring the snacks and the dice.
