The D&D World Builder That Updates Itself
Most world builders need you to update them. Saga20 does it for you. Record a session, get a summary, and every NPC, location, and faction page updates on its own.
Free to start. No credit card required.
Record. Summarize. Build your world.
Stop writing mid-session. Record, upload, and Saga20 does the rest.
Just Hit Record
Upload your session audio after you play. Any device, any quality. No setup needed before the game.
Instant Session Summary
Saga20 writes the session notes and identifies every character, location, and faction mentioned in the recording.
Your Wiki Updates
Every entity page gets a new timeline entry for what happened. No manual editing, no copy-pasting notes.
Your entire world, always organized
Characters, locations, factions, items. Each gets its own flexible document, like a Notion page built for your campaign. Add a name, icon, cover image, and notes. @-mention other entities to link your world together. The search actually works.
- Flexible documents: name, icon, images, and free-form notes
- Characters and NPCs tracked with full detail pages
- Locations, factions, and items all in one place
- @-mention any entity to link your world together
- Search everything instantly across your campaign
Your wiki updates itself after every session
Play the session. Upload the audio afterward. Character and location pages update from what happened in the game, not from you typing into a wiki at midnight. That's the part World Anvil and Kanka still leave to you.
- Characters gain history entries from session events
- Locations gain history entries from session events
- Key events captured on every entity page automatically
- No manual wiki editing after sessions
- Full campaign history, always accurate
Wiki updates after sessions
Every connection, mapped automatically
The campaign graph turns your world into a visual map. Every @-mention creates a connection. Every session adds new ones. You end up with a living diagram of your campaign that nobody had to draw.
- Every @-mention between entities becomes a visible link
- Filter connections by entity type or relationship
- See which NPCs are connected to which factions at a glance
- Grows with every session automatically
Is Saga20 right for you?
Saga20 is not every DM's tool. Here's an honest breakdown.
Saga20 is for you if...
- You run sessions and forget to update your notes afterward
- You're already three sessions behind on your campaign wiki
- You use Notion or Google Docs and constantly duplicate work
- You want your players to have a living reference for the campaign
- You're starting a new campaign and want everything tracked from session one
- You started mid-campaign and need to catch up fast
Switching from Notion? See how they compare.
It's probably not for you if...
- You want to build a detailed world bible before your campaign starts
- You prefer writing all your own lore and world-building documents by hand
- You don't record your sessions (though you can still use the wiki manually)
- You need map tools like hexcrawl grids or dungeon layouts (we don't do that yet)
How Saga20 compares to other D&D world builders
World Anvil and Kanka are good tools if you want to build your world wiki yourself. Saga20 is for the DM who wants it to happen automatically.

Campaigns that stopped losing track
“Saga20 has become an invaluable tool for me as a Pro GM running 4-5 weekly campaigns. My players enjoy and appreciate the detailed session summaries.”
Carl SwanPro GM“This is a fantastic tool that will save you time and energy, and will also encourage your players to interact with the world and story beyond the session. Absolutely worth it.”
Gubmann GamesD&D Content Creator“Honestly did not expect this to work as well as it did. my table is SO loud but it still picked up everything perfectly.”
“It's like having a dedicated campaign archivist sitting at your table. You record your session, and it turns that recording into summaries while building a living campaign wiki with your NPCs, locations, factions, and ongoing story threads.”

GavinskiDM of Ashes of the Forgemaster“I've looked at a bunch of recording tools and it's the integration with the Wiki that really stands out, fulfilling my need for everything to be connected and helping my players come up to speed quickly.”
JandarGM of 26 years“This is a stupid easy decision. It breaks down any session you have, records it in a wiki for your own purposes and for your players via a wiki webpage and its super easy to navigate in the midst of a campign. Not too shabby of a price either for what it's used for too.”
Dark ChewyDM of 7 years“I'd say that Saga20 is a tool that even if boiled down to just the recaps, would be a compelling offer. My players love knowing exactly what happened last week. It helps our notes, it helps our continuity, and it keeps me as a DM from accidentally adding plot holes.”
IsItWamDM of 8 years“I have long wanted to catalogue the adventures of my Actual Play "Legends of Elzorya" but was never able to keep up with a living wiki on my own. Being able to bring in the session recaps and build out the wiki as we play has been a game changer in how I organize this living world.”
