Shipped and coming

We would rather you know exactly what you are signing up for. This page is the canonical list, and the rest of the site defers to it. Changes are dated as they land on the changelog.

Eldritch OS is pre-launch and in alpha. Things will break. We bring in a small group of GMs at a time to run sessions on it and tell us what did — join the alpha playtest if that is you.

Working today

At the table

• Virtual tabletop with maps, tokens, and grid snapping
• Fog of war, with hide and reveal for individual tokens
• Initiative tracking and condition tracking per token
• Drawing and measurement tools
• Prepared scenes with mid-session switching
• Live sync between the GM and player views
• Physics-based 3D dice

Characters and content

• Guided character builder and full interactive sheets
• D&D 5e, grounded in SRD 5.2
• SW5E as a second ruleset
• Character import from D&D Beyond (how to)
• Compendium with SRD content built in
• Homebrew authoring alongside built-in content

Campaign management

• Campaigns, sessions, and scenes
• Campaign-scoped roles for GMs and players

AI

• Rules and reference assistance from inside a session
• Generated portraits
• Generated NPC voices

AI features run against your campaign’s context and are always GM-mediated: they draft and suggest, and the GM decides what reaches the table.

For developers

• REST API with Swagger documentation

Still ahead

These are designed and in progress. They do not work yet.

• MCP servers — structured access to rules, adventures, and session state for AI clients
• Desktop GM screen app — a companion app driving a separate player-facing display
• Visual adventure authoring — graph-based scene and encounter building
• Phone companion app — a player-side character sheet that broadcasts rolls into the session
• Campaign and character export — take your material with you when you go

Keeping this honest

If you find a claim anywhere on this site that this page does not support, that is a bug and we want to hear about it — tell us.
