Rolegend and Dungeons Deep

Dungeons Deep is building the whole tabletop - map, tokens, voice, authored campaigns. Rolegend is building one thing well: a rules engine the narrator cannot argue with.

What Dungeons Deep is

Dungeons Deep is an AI Game Master platform from Portalis AI, Inc., currently in beta. It runs human-written adventures on its own game system through a virtual tabletop with a battle map, character tokens and a Game Master that narrates aloud. Play is metered in Turns, sold as a subscription allotment.

What we could verify

• Dungeons Deep runs its own game system. Its blog describes it as "the Dungeons Deep Ruleset, an original game system compatible with fifth edition", and says the platform is not a version of, or connected to, any other game on the market. (source, checked 2026-07-31)
• It is a full virtual tabletop: their write-up describes a battle map and grid on screen with character tokens, fog of war and a character sheet, with combat running through code rather than improvisation. (source, checked 2026-07-31)
• As of their own post dated 29 July 2026 the product is in closed beta, and lists multiplayer and image generation as roadmap items that have not shipped yet. (source, checked 2026-07-31)
• The free tier is metered rather than feature-limited: the same post describes it as the full platform with a set number of Game Master turns each month. (source, checked 2026-07-31)
• The unit of billing is a Turn, defined in the terms as one instance of the Game Master speaking. Subscriptions include an allotment of Turns per billing period, unused Turns do not carry over, and Turns can also be bought separately. (source, checked 2026-07-31)
• There is a second currency, Crowns, for optional items such as dyes and alternate Game Master appearances. The terms state Crowns are not money, have no monetary value and cannot be redeemed for cash. (source, checked 2026-07-31)
• The beta clause is explicit that game data, characters, campaigns and account data may be modified, reset or deleted during beta, including without notice, with no commitment to preserve anything created during it. (source, checked 2026-07-31)
• The Game Master speaks: the site advertises narration in spoken natural language, and the terms describe player voice input being recorded and passed to third-party text-to-speech providers. (source, checked 2026-07-31)
• Its game data is attributed to System Reference Document 5.2 under the Creative Commons Attribution 4.0 International License, which is a newer SRD release than most of the category uses. (source, checked 2026-07-31)

What Dungeons Deep does better

• Tactical play you can see. A battle map and grid, character tokens and fog of war on screen. Rolegend has none of that - no map, no grid, no tokens.
• Spoken narration. Their Game Master reads the scene aloud and takes voice input. Rolegend is text on a page and nothing else.
• Authored content. Their campaigns are written by people and then run by the AI, rather than improvised around you from a blank world.
• Playing with other people. Party play is in their design and in their terms today, and it is not on Rolegend's roadmap at all.

What Rolegend does differently

• Keystone Engine enforces the rules on the server, before any narration exists. It owns every die roll, modifier, hit point and spell slot. ROWAN narrates the world, is handed the result, and cannot change a number or roll again.
• We publish what is enforced and what is not, section by section, at /rules-coverage, so you can check the gaps before you start rather than find them in session three.
• We implement the System Reference Document 5.1 under CC BY 4.0 and reproduce the attribution in full at /legal/attribution.
• Solo only. There are no shared tables and no invites. You can run a party of up to six characters, but every one of them is yours.
• No battle map and no grid. Movement, cover, opportunity attacks and flanking are not enforced, and we say so on the coverage page rather than implying otherwise.
• Async play-by-post. You write a turn, the world answers, and you come back whenever - fifteen minutes at a time if that is what you have.

The full account of which fifth edition rules our engine enforces, and which it does not, is at rules coverage.

Pick Dungeons Deep if

• You want to see the fight. Tokens on a grid, fog of war, and a position that means something.
• You would rather be dropped into an adventure somebody wrote on purpose than into a world improvised around you.
• You want a Game Master with a voice, and you would rather speak your turn than type it.
• You expect to bring friends eventually, and you want a platform that is already built around a party at the table.
• You are comfortable playing on a beta whose terms say your campaign may be reset.

Pick Rolegend if

• You play alone, and you are not waiting for anyone to be free on Thursday.
• You want to know exactly which rules are enforced before you commit a character to them.
• You want a die roll that was decided by code before the sentence describing it existed.
• Text is enough. You do not need a map, tokens or a voice to picture the room.
• You play in gaps rather than sessions, and want the campaign to still be there in a fortnight.
