Worldbuilding
Saga20 is the campaign tool that keeps up with your table. It is a full world builder, a campaign wiki, a session summarizer, a character sheet system and a shared player portal, and all of it runs off one action: hit record. Play the session, upload the audio, and Saga20 works out who spoke, writes the recap, and pushes what happened into every world page it touched. Characters, locations, factions and items each keep their own page, their own timeline, and a link back to the session where it happened. Most world builders need you to update them. This one updates itself. It works for every TTRPG system, from D&D across all editions to Pathfinder 1e and 2e, Call of Cthulhu, Cyberpunk RED and Vampire: The Masquerade, with character sheets built into the app. The app is quickly growing in popularity and is already being used and trusted by thousands of GMs.
Description
Every campaign wiki dies the same death. Immaculate for four sessions, then the group plays a long night, nobody writes it up, and a month later the wiki describes a campaign that no longer exists. Saga20 fixes that at the source. The session is the input, and the world updates because you played, not because you did homework afterwards.
Underneath the automation is a proper world builder. Characters, NPCs, locations, factions, items, deities, starships, corporations, clues, house rules: anything in the campaign gets a real page, with rich text, images, custom icons and cover art, organized into folders and templates and custom entity types for whatever the world needs. Search reaches every page instantly. A campaign graph draws who knows whom. Interactive maps carry routes, regions, pins and the party's current position. Build it all by hand if that is the fun part, or you can import an existing world across from Obsidian, Notion, Google Docs or World Anvil and carry on from there.
You can then upload session recordings to automatically update your world wiki. Anyone at the table can record, on a phone, a dedicated mic, Discord or Zoom, and nobody else has to install anything. Saga20 generates the Session Notes including choices, clues, quests and consequences that happened during the session then automatically updates the world pages so you'll always have an up to date wiki without having to spend hours after every session.
It is not only the GM's tool but a tool for the entire table. Players can read the campaign and session notes without an account, or choose to claim their own characters, keep their character sheets on the same page as the story, and arrive at the next session actually remembering the last one. The wiki can be themed to match the setting and published on its own link. Prep, play, notes and the whole table, in one place.
