“I've completely switched over to Trails Weaver this year. I'm not using any other tool for keeping GM notes.”
“Being able to visualize what clues were at what locations and move things around was soooo satisfying.”
“I just signed up for the monthly Pro. While I like Legend Keeper, this is so much better for the way I write, visualize and organize.”
A canvas where cards nest inside cards
A Miro-style board for your whole world. A coast holds its harbor, the harbor holds its people. Nothing moves unless you move it.
Nest to any depth
Put an element card inside another element card. A region holds its cities, a city holds its taverns, a tavern holds its regulars. No other worldbuilding app does this.
Sticky notes with real rich text
Not scraps of plain text: a note here can hold headings, tables, to-do lists, and images, all rendered right on the board.
Draw the connections
Link cards with arrows you can label, color, and restyle. Show who answers to whom and what road leads where.
Notes that think they're pages
Headings, tables, and to-do lists, right on a sticky. Connect them when the plot does.

Every relationship, in one graph
Every connection you add lands here on its own. A living web you can drag, filter, and explore.
It builds itself
Add a row to any page's relations table. The graph draws the link for you.
A graph you can feel
Drag any node and the whole web reacts until it settles, like Obsidian's graph.
Follow one thread
Filter to any character, place, or faction and see only their ties.
Maps that go as deep as your world
Upload a map, draw on top of it, and tie every pin to the world behind it.
Bring your own map
Upload any image, paste a URL, or reuse one you've saved. Hand-drawn, satellite, or fantasy.
Roads, regions, and pins
Draw roads and territories with colors and labels, then drop pins for towns, dungeons, and secrets. Tie any of them to an element and open its full page straight from the map.
Zoom layers
Reveal detail as you go deeper: continents → regions → cities → districts. Zoom back out and crowded pins gather into clean clusters.
Pages with real depth
Open any card into a full page. Stack properties like bricks.
Your own types
No fixed schema: gods, ships, spells.
@mention anything
Click to jump anywhere.
Secrets stay secret
Readers and players never see them.
Drop in any property, in any order
Family trees for more than families
Bloodline or chain of command: the tree lays itself out either way.
One tree, any hierarchy:
The three views people switch for.
Each exists somewhere, in pieces. All three in one app: that's the part you won't find elsewhere.
Built for game masters. Loved by writers.
