Comparison
wilds.ai vs AI Dungeon
wilds.aiis the AI Dungeon alternative built around the two complaints that dominate AI Dungeon's Steam reviews and r/AIDungeon threads: characters that forget, and rules the AI improvises. wilds.ai runs nine neuroscience-backed memory mechanisms so companions never lose track of you, and thirteen deterministic game engines so combat math, dice, and consequences are enforced by code instead of guessed by the model.
The short version
AI Dungeon was the 2019 text-adventure pioneer. Its core architectural choice — relying entirely on the LLM's context window for state — is the source of the chronic memory failures users report. wilds.ai is a different architecture: persistent memory store outside the context window, real game engines that own the rules, and a multi-family runtime that supports tactical RPGs, roguelikes, 3D dungeons, visual novels, survival, and more in addition to text.
Feature-by-feature
| Feature | AI Dungeon | wilds.ai |
|---|---|---|
| Memory model | Single LLM context window; "memory entries" injected as prompt prefix. Earlier facts drop as the conversation grows. | 9 neuroscience-backed mechanisms (spacing, emotional tagging, chunking, interference resolution, context-dependent retrieval, reconsolidation, generation, sleep, personality drift). Persistent across sessions. |
| Game engines | None. The AI improvises dice, combat, and rules each turn. | 13 deterministic engines: combat resolution, dice rolls, inventory, progression, survival pressure, objectives with DAG prerequisites, deferred consequences, ending detection. |
| Game families | Text adventure only. | 10: TTRPG with tactical grid maps, roguelike with procedural dungeons, board games, visual novels with character expressions, survival horror, real-time 3D dungeons, point-and-click, narrative sandbox, platformer, interactive fiction. |
| Voice | None. | Streaming per-character voice synthesis. Each NPC gets a distinct voice. Player-to-player voice chat in multiplayer. |
| Multiplayer | None. | Real-time co-op via WebSocket. AI companions join lobbies and chat in character. Turn modes adapt to combat tempo. |
| Companions | No persistent companion entities. | AI companions with HEXACO personality, PAD emotional states, 8 facial expression variants, tiered persistent memory across sessions, and three chat modes (Auto / Character / Assistant). |
| Content policy | Mature content has been restricted multiple times; 2021 controversy over human review of flagged user content. | 4 tiers (safe, standard, mature, private-adult). Uncensored OpenRouter routing on mature/private-adult. No human review of private content. No training on user data. |
| Creator studio | Scenario editor with prompt fields. | 28+ panel studio with autosave, AI-assisted authoring, scene background editor, NPC HEXACO editor, objective DAG editor, branching ending editor, dialogue + dynamic lore systems. |
| Open source | Closed source. | Built on AgentOS — open-source AI agent runtime at github.com/framersai. |
| Pricing | Free tier + paid subscriptions for "energy" / model access. | Free tier with full memory + engines + studio. Paid tiers unlock premium models and uncensored tiers. |
Migrating from AI Dungeon
Paste your AI Dungeon scenario prompt into the wilds.ai world creator and the compiler builds out regions, NPCs, factions, quest objectives, combat mechanics, items, and cover art around it. Personas you used in AI Dungeon become saved identities; recurring AI characters become first-class companions with their own persistent memory store. Save points become version-pinned session checkpoints that survive even after the creator updates the world.
