From your first universe to your game session, here's one way to get started with Loreloom.
- 1
Create your universe
A private universe in two clicks. Custom calendar, currency, eras: everything is adjustable to fit the world you imagine — and if your heroes travel between planes, planets or kingdoms, each one can carry its own calendar and currency, linked to yours.
- 2
Document your characters and places
Compendium with reusable infoboxes, parchments for drafts, canvases for session ideas. Everything is linked by shared tags.
- 3
Trace history and geography
A chronology with colored eras, family trees, an atlas whose pins link back to your articles. The fabric of your world appears.
- 4
Control the reveals
Context whitelist: choose exactly who sees what — players, DM, co-authors. Prepare your surprises without spoiling anything.
A living Compendium
A living Compendium
Your world's knowledge, woven thread by thread.
- Rich editor: hideable spoiler blocks, polished formatting, and article-to-article links suggested as you type.
- Reusable infoboxes: create a Character, City or Artifact template once, instantiate it everywhere.
- Multiple images per article with tabs, captions and a default choice — no more improvised galleries.
- Full-text search and tag filters to find any article in an instant.
Interactive chronology
Interactive chronology
Make centuries speak at a glance.
- Fully configurable calendar: your months, days and eras, but also your moons (cycles and phases), suns (sunrise, sunset, solstices) and seasons — the whole chronology follows your world's astronomy.
- Several calendars for one world: declare another plane's or a neighbouring kingdom's, align it with yours, and your dates show their equivalent — you can even enter them in either one.
- Three views of the same story: a vertical timeline for the flow of centuries, a calendar to explore a year day by day, a yearly table to scan it all at once.
- Point events or periods (vertical bars) on a readable, smooth vertical timeline.
- Grouping by custom eras — each era carries its color and structures the reading.
- Direct links to relevant Compendium articles and synchronized minimap for long navigation.
SECRETS ON MANY LEVELS
You control who sees what
Contexts aren't a simple hidden/visible switch. You attach each plot to a context, then decide, participant by participant, who can access it: one player sees one secret, another sees two, and you see every shared context.
Access to the public story only — 1 context.
- Every plot is tied to a context; a participant only sees the contexts you grant them.
- Graduated access: one player can see one, another two, without revealing anything to the first.
- You, the Dungeon Master, see every shared context — and reveal each layer when the moment is right.
Family trees
Family trees
Draw the ties of blood, alliance and betrayal.
- Interactive trees: zoom, pan, and a view mode to read without disturbing anything.
- Each member can be linked to their Compendium article, whose infobox shows in a side panel.
- Free-form links: marriage, descent, adoption, mentorship… each with its own line style and colour.
- Deceased members flagged, customizable legend — and a whole tree can stay secret.
Canvases
Canvases
The free space where your world's ideas take shape — and connect.
- Free-form canvases, outside the Compendium hierarchy — an investigation, a mission plan, a faction tree, a session draft.
- Typed notes with tags scoped per canvas: organize without imposing premature structure.
- Kanban or linked graph view: quick visual overview, cross-search, move from one canvas to another.
- Ideal for tabletop sessions: jot down what deserves to be promoted to the Compendium later.
Atlas & interactive maps
Atlas & interactive maps
Your maps are not images — they are gateways.
- Multiple maps per universe, quick selection from the sidebar.
- Typed pins (capital, ruin, battle, route…) with shared tags and rich tooltips.
- Each pin can link to a Compendium article, a timeline event, a trade house.
- Free base-map editing — upload your Wonderdraft, Inkarnate or scanned pencil rendering.
Character sheets
Character sheets
Tailor-made sheets for any game system — no spreadsheet required.
- Per-universe templates built by drag & drop: tabs, blocks and typed fields.
- 17 field types including formula-computed values, repeatable lists and a currency converter.
- Link a sheet to its Compendium article: portrait and lore follow the character.
- Shared render engine: the same sheet reflows from desktop to mobile.
Inventories
Inventories
Far more than a list of items: a living inventory attached to each character.
- Per-inventory typed custom columns: number, choice, yes/no — beyond plain text.
- Tagged items (colored tags with icons), server-side search, and sorting by name, quantity, or tags.
- Three views to choose from — table, list, cards — and quick quantity editing without opening a sheet.
- A universe catalog to capitalize on recurring items and reuse them across characters.
Logbooks — the story, day by day
Logbooks — the story, day by day
What the Compendium never tells, what the timeline never feels.
- One day, one page. Turn the days like you turn a notebook, on your world's calendar — not ours.
- Three readings of the same story: the day page to write, the calendar to spot the full days, the year table to sweep through it all at once.
- One logbook per character, per campaign, per secret. Tie it to its sheet and its article: the notebook becomes a way into the rest of your world.
- Private by default. Open it up to your table when you're ready, or hand the pen to someone else — you pick who, and how far.
Tabletop — everything at hand
Tabletop — everything at hand
Players, keep your shortcuts and game aids in sight; GMs, go as far as building your own custom GM screen. NPCs, gauges, clocks, conditions: all laid out on a grid that only moves when you say so.
- Free-form cards on a grid: place them, resize them, fold them down to a single line. One tabletop per campaign, per scene or per character — and on mobile, one card per tab.
- The same fields as character sheets: gauges, clocks, checkbox tracks, labels, formulas. Everything that shifts during the session, tracked in one tap.
- Link a card to a sheet: its hit points and resources show up and can be edited right from the card, with no copy drifting apart. Link it to an article: its portrait dresses the card.
- Lock the content or the layout, archive what you no longer need, keep your go-to cards as presets. And it's yours alone: nobody else, not even the GM, sees your tabletop.
Parchments — free writing
Parchments — free writing
A personal space for ideas that haven't found their place yet.
- Blank page for drafts, story fragments, monologues, raw ideas — no imposed structure.
- Local autosave: a browser crash never costs you a writing session again.
- Select a passage, right-click → "Create a note on a canvas" or "Create an article". Your parchments flow into structure when the moment is right.
- Stylized reading mode: enjoy the comfort of a quiet parchment, or switch to immersive mode to re-read what you wrote differently.
DM combat tools
DM combat tools
Keep the rhythm at the table without improvising everything.
- Ordered initiative, turn and condition tracking.
- Populate a group of NPCs in seconds — a band of bandits, pirates or guards added in a few clicks.
- Dice rolls configurable per universe (number of dice, faces) — adapt to your system.
- Designed to live alongside the fiction — not replace it.
Trade houses
Trade houses
Simulate a merchant empire month by month.
- Goods, transporters, buyers and trade routes with automatic cost calculation.
- Revenue-generating buildings with monthly simulation (success, losses, bonuses).
- Recurring fees, global bargaining, convoy logs — your merchant-lord bookkeeping.
- Per-universe customizable currency: define your own denominations and ratios.
Build it, then play it — all in one place
Loreloom isn't only a worldbuilding workshop: it's also the toolkit you keep open during the session, on any screen.
Everything in one place
From the Compendium to the combat tracker: one app, not ten tabs or ten subscriptions.
From worldbuilding to the table
Prep your world, then run the session with the same tools at hand — sheets, tabletop, timeline, combat, canvases.
On every screen
Responsive and installable like an app: desktop, tablet or phone, wherever you play.
A world under Loreloom
To make things tangible, here's what a classic fantasy universe looks like once placed in the tool.
Characters, cities, artifacts, deities, factions — woven into a web of clickable links, article to article.
Four eras, thirty-two key events, six long periods (wars, plagues, reigns).
Four family trees with marriages, descents and secret links — 73 members in total.
Kingdoms, capitals, ruins, battles, trade routes — each pin links to an article.
Plots invisible to players, revealed one by one over the campaign.
Drafts, monologues, ideas that will eventually become articles or notes.
A universe of this size fits in a Loreloom folder, accessible from the sidebar like a book you could open to any page.
