LoreKeeper vs DungeonsDeep: An Honest Comparison

What are LoreKeeper and DungeonsDeep, in a nutshell?

DungeonsDeep is a newer AI tabletop RPG platform built around a visual table: a battle map, grid, character tokens and character sheets on screen at once, with an AI Game Master at the head. It runs its own engine, the Dungeons Deep Ruleset, described as compatible with fifth edition, handling dice, combat math, conditions and encounter difficulty. Campaigns are authored by a tabletop writer, then run by an AI that adapts to your party. Campaign memory lives at the platform level — “your choices, NPCs and plot threads live in the campaign system instead of a context window.” One subscription brings up to four non-paying friends.

LoreKeeper is a mature live product built engine-first around D&D 5e-inspired mechanics enforced server-side — 40 conditions, 7 damage types, spell slots, death saves, initiative, karmic dice — then layered with real-time multiplayer for up to 6 players (invited friends join free), a Codex living wiki, AI image generation, an Arena PVP/PVE mode, and native support for four languages: English, Spanish, Portuguese and Catalan. Pricing is EUR 7.99–19.99/mo with a permanent free tier of 20 daily turns.

Both platforms agree on the core principle — the engine computes outcomes, the AI narrates them — and both keep campaign facts out of the context window. The practical differences are the ruleset, the visual tabletop, languages, pricing structure, and how much of each platform's claims have been checked by anyone outside the company.

How do the rules engines compare — 5e-inspired vs a proprietary ruleset?

Both platforms resolve mechanics in code, not in the language model. Neither lets the AI hallucinate a damage number. The difference is which rules you are playing.

DungeonsDeep: the Dungeons Deep Ruleset

DungeonsDeep ships an original system it calls compatible with fifth edition, with a dedicated engine for dice, combat math, conditions and encounter difficulty. Building a coherent rules engine rather than leaning on the model is the right instinct, and it earns DungeonsDeep a pass on mechanics. The catch is the same one every proprietary system carries: it is not the 5e SRD. Your existing 5e character sheets do not import, class features and spell interactions are whatever the Dungeons Deep Ruleset says they are, and “compatible with fifth edition” is a claim you can only fully test by playing it.

LoreKeeper: a D&D 5e-inspired engine, server-side

LoreKeeper built a D&D 5e-inspired engine and enforces it server-side: 40 conditions, 7 damage types, 7 creature types, initiative order, spell slots and death saving throws. Every mechanical outcome is resolved before the AI sees it — the narrator turns results into prose, it never invents them. A signature touch is karmic dice: after five consecutive failures, the next roll gets advantage, so a cold streak never wrecks a session. If you want combat that feels like the 5e you already know, LoreKeeper is the closer match.

The visual tabletop — where DungeonsDeep is ahead

Credit where it is due. DungeonsDeep puts a battle map, grid and character tokens on screen alongside the character sheets today, so positioning, range and line-of-sight are things you can see and move, not just describe. For players who came to tabletop through a grid, that shipped visual layer is a real advantage right now.

LoreKeeper's standard campaign session is narrative-first: the engine tracks the full combat state — positions, conditions, initiative — and the AI narrates it as prose, theatre-of-the-mind style, which keeps setup friction near zero and travels well to mobile. A dedicated tactical combat mode with a grid and tokens is in active development for campaigns, on the same rules engine, and is not available yet. So today, if a visual battlefield is essential, DungeonsDeep is the one that already has it.

Memory, and the audit gap

Both platforms solve the same problem the same way in principle: campaign facts live in a structured store outside the model's context window, so session 40 can still see session 1. DungeonsDeep frames this as “memory as record” — character state, NPC relationships, inventories and plot threads tracked in the campaign system rather than recalled from chat history. LoreKeeper uses entity dossiers (a canonical record per NPC, location, quest and thread), narrative checkpoints (typed events that trigger a memory update when something material happens), and a source resolver that assembles the relevant dossiers into each turn — compiled into the Codex living wiki. The mechanism is explained in why AI Game Masters forget your campaign.

The difference is evidence. LoreKeeper published a 40-round end-to-end test: 63 canonical entries (18 NPCs, 14 locations, 9 quests, 5 threads), with the NPC introduced in round 30 still intact — same character, same items — in round 40. DungeonsDeep states it “refused to ship a memory system that couldn't keep up” and that it “does not forget,” but we have not found a public, reproducible audit of that claim from anyone outside the company. It may well hold up. As of this writing, nobody has shown their working.

How much do LoreKeeper and DungeonsDeep cost?

DungeonsDeep pricing (per its published pricing page)

• Free trial: 75 one-time turns
• Adventurer: $9.95/month — 750 turns (~10 hours of solo play)
• Hero: $19.95/month — 1,600 turns
• Champion: $39.95/month — 4,000 turns
• One subscription brings up to 4 non-paying friends

LoreKeeper pricing

• Free: 20 daily turns (recurring) + 10 welcome credits, 1 campaign, 1 character — no credit card
• Adventurer: EUR 7.99/month — 200 rounds, 4 characters
• Hero: EUR 9.99/month — 500 rounds, unlimited characters, 3 editable worlds, autonomous NPCs
• Legend: EUR 19.99/month — unlimited rounds, 1.5x AI context
• Credits never expire; invited multiplayer guests play free

The structural difference is the free tier. DungeonsDeep gives you 75 turns, once — spend them and you upgrade or stop. LoreKeeper gives you 20 turns a day, forever. One is a demo; the other is a standing invitation to keep playing without paying. On paid plans the entry prices are close ($9.95 vs EUR 7.99), but DungeonsDeep's are turn-metered at every tier below Champion, so heavy months run dry.

The honest weaknesses of each

No platform in this space is finished. Here is where each one is weak.

Where DungeonsDeep is weak

• No recurring free tier. 75 trial turns, then a paywall — you cannot maintain a light, ongoing habit for free.
• Turn-metered pricing below the top tier. $9.95 buys ~10 hours of solo play a month; an active campaign outpaces it.
• Proprietary ruleset. “Compatible with fifth edition” is not the 5e SRD — no character import, and rule edge-cases are whatever the Dungeons Deep Ruleset decides.
• Pre-authored campaigns. Writer-authored adventures give polish, but the emergent sandbox is narrower than a fully open campaign.
• English only. No advertised support for other languages in the UI or narration.
• Unaudited memory claim. “Does not forget” is a strong claim with no public, reproducible test behind it yet.
• Newer entrant. Smaller track record, listed among “emerging” platforms.

Where LoreKeeper is weak

• No shipped visual battle map. The standard session narrates combat rather than showing it on a grid; a tactical combat mode is in development for campaigns but not available yet, so for token positioning today DungeonsDeep is ahead.
• Round-metered on lower paid tiers. Adventurer (200 rounds) and Hero (500) cap monthly play; only Legend is unlimited.
• Fewer ready-made modules. LoreKeeper leans on custom and AI-built worlds; it ships fewer writer-authored campaigns you can just drop into.
• D&D 5e-inspired, not licensed 5e. Close to the rules you know, but not a certified SRD implementation.

How do LoreKeeper and DungeonsDeep compare feature by feature?

Which is better in 2026: LoreKeeper or DungeonsDeep?

Pick DungeonsDeep if a shipped visual tabletop is the point — you want a battle map with grid and tokens today, you like the idea of writer-authored campaigns run by an AI, and turn-metered pricing fits how much you play. It does that layer well right now; LoreKeeper's equivalent is still in active development.

Pick LoreKeeper if you want a D&D 5e-inspired engine rather than a proprietary system, a permanent free tier instead of a one-time trial, real-time multiplayer where friends pay nothing, play in Spanish, Portuguese or Catalan, or you simply want the platform whose memory claims have been tested in public.

One last note on the framing. DungeonsDeep uses the LoreKeeper definition of what an AI Game Master should be, and independently arrived at the same explanation of why they forget. We take that as a compliment. It would just be a more useful compliment if their rankings included the platform they are citing. Until then, this comparison is the one that puts both of us side by side — strengths, prices, and the parts still waiting on an audit.
