Session mode — your world at the table
How it works
Three phases that close the distance between the world in your head and the story your players get to live.
Build your world
Write articles with automatic wikilinks. Every NPC, location, faction, and secret connects as you type. The relationship graph builds itself. Maps anchor your lore to geography. Stat blocks are native to your system — not retrofitted.

Run your table
Session mode is built for a tablet propped at the GM screen. Pull up any NPC or location in two keystrokes. When the party goes off-script, Off-Script reads your own notes and hands you a paragraph you can say aloud — without losing the table.

Share with players
Every campaign has a player portal your players can browse between sessions. Reveal NPCs, locations, and lore with one click — when they’ve earned it. Players see character arcs, session recaps, and the world as it unfolds.

When you need it now
The party walks somewhere you only half-prepped. You need to know who’s there, what they want, and what happened last time — now, not after two minutes of scrolling a wiki. Skryrún puts your whole world a keystroke away.
Where the world lives
The session tools only work when there’s a real world underneath. Skryrún is where you build it: structured articles with automatic cross-references, interactive maps your players will eventually explore, and a relationship graph that shows you what you’ve built at a glance.
For everyone at the table
Every player invited to a campaign gets the portal, the backstory builder, and session recaps — at no cost to them. No account required to view what you’ve revealed. No paywall between your players and their characters.
Solo GMs running homebrew, streaming creators sharing a living world with an audience, players keeping their character arcs between sessions — one platform, one price tier for the GM, zero cost for everyone else.
The story is still yours. We just make it easier to share.What players see →
Skryrún AI, on every account
Runes are how you spend Skryrún’s AI — Off-Script scene synthesis, instant recall, lore writing, the improv tools. Each costs a small number of Runes.
Every account comes with a monthly allowance: 25 free, 100 on Weaver, 600 on Runekeeper. They refresh monthly. Need more? A $5 pack adds 300, no expiry.
Off-Script is the Rune feature most GMs come for.
Your party was supposed to investigate the docks. They went to the temple district instead. You wrote 2,000 words about that district six months ago — three NPCs, two factions, a relic in the high altar. Off-Script reads all of it and gives you a paragraph you can read aloud, in your own voice, drawn from your own notes. You don’t lose the table while you scramble.
1 Rune per lookup. 25 free every month.

We play nicely with the rest of your stack
We don’t roll your dice. We don’t run your combat math. We don’t move tokens on a battle map. That’s what Foundry, Roll20, and Owlbear Rodeo do, and they do it well.
Skryrún is the narrative reference layer beside them. Put your VTT on one monitor. Put Skryrún on the other — or on a tablet at the table. They handle the simulation. We handle the story.

Limited offer
Skryrún is built by a GM, for GMs. The first 250 accounts get Weaver free for one year — no card, no auto-renew, no catch. You also get 100 Runes a month for the full year. In exchange, we ask for honest feedback, bug reports, and the willingness to tell us when something doesn’t work at your table.
After the year, you decide if it was worth $5/month. We think it will be.
Straight answers
Yes. Chronicler is free forever. One world, 25 Runes a month, every core feature. No trial clock, no card to start. You can run a real campaign on Chronicler for as long as you want.
Runes are how Skryrún's AI features get used. Off-Script (the at-table scene lookup) costs 1 Rune. Lore generation costs 2. Multi-turn AI analysis costs 3. Every account gets a monthly allowance: 25 free, 100 on Weaver, 600 on Runekeeper. They refresh monthly. Need more? Buy a pack of 300 for $5, never expires.
Players get a browsable portal scoped to their campaign — the lore, NPCs, and locations you've chosen to reveal. They can manage their character (backstory, arc, portrait) and read session recaps. No subscription needed. A player just needs the invite link from their GM.
No. We don't capture audio, ever. The session companion is a reference tool — you show it to your players when you want, and that's it. No mics, no transcripts, no consent forms required for your table.
No. Runes only reason over what you've already written. They don't invent lore from scratch. Off-Script reads your own notes and hands the scene back in your voice. Lore generation extends what you've already started, in the tone you set.
Yes. The Import Hub at /import accepts WorldAnvil exports, LegendKeeper .lk files, Kanka JSON exports, and Obsidian vault ZIPs. Wikilinks, images, entity types, and timeline events come over. Platform-specific CSS does not.
Yes — that's how most of our GMs run it. Skryrún is the narrative reference layer. Foundry / Roll20 handle the battle map, dice, and combat. Put one on each monitor (or Skryrún on a tablet at the table) and they work together cleanly.
Daggerheart, D&D 5e, Pathfinder 2e, Call of Cthulhu, and system-agnostic worlds. Stat blocks are native per system, not retrofitted.
No. Your worldbuilding stays yours. We don't sell user data, we don't train models on user content, and your work is exportable in JSON or Markdown at any time.
Export your world with one click. You own your lore. We make it easy to walk away because we'd rather you stay because we earned it.
One platform. The whole table.
Free forever. One world, 25 Runes a month, every core tool — no trial clock, no card to start.
