Roleplay that remembers.
A roleplay platform for writers who want continuity, not amnesia. Characters are built on a three-tier memory system — raw context, episodic recall, and a structured relationship graph — so they remember what matters. Now with Dungeon Mode: play solo tabletop RPG adventures with an AI dungeon master.
No credit card. Free tier doesn't expire.
What's here, what's coming.
We'd rather tell you the truth about what works today than promise things that don't. Here's the honest state of the platform.
Memory that lasts
Three tiers of memory: the raw conversation, vectorized summaries of past scenes, and a structured graph of facts, entities, and relationships. Your character knows who they trust, what they owe, and what you argued about last week — without you reminding them.
Most platforms use vector recall and call it memory. We add the graph layer that actually prevents the 'who are you again?' failure mode.
Bring your own model
Connect your own OpenAI, Anthropic, or OpenRouter key and route to whatever model you want — including ones we don't host. Pay the provider directly; we don't mark up their pricing.
The model gateway is provider-agnostic and OpenAI-compatible. Local self-hosted inference is on the roadmap.
Group scenes & persistent worlds
In progressWorlds, factions, and campaigns as first-class entities separate from any one character — so multiple characters share consistent lore. Multi-character scenes and turn-by-turn play are in active development.
Solo dungeon mode with full game mechanics is live now. Multiplayer party sessions are next on the build list.
Play solo tabletop RPGs with an AI dungeon master.
Dungeon Mode is a complete tabletop RPG engine built into CharacterBug. The AI is your Game Master — it narrates the world, controls monsters and NPCs, and tracks everything mechanically. You just describe what your hero does.
Real combat, real dice
Initiative rolls, attack rolls, damage dice, armor class, saving throws — all resolved by the system, not improvised by the AI. Hit a wolf for 7 damage and its HP actually drops. Defeat it and you gain XP, gold, and loot.
Character sheets that matter
11 classes, 8 races, 15 feats, 8 backgrounds. Your character has ability scores, HP, inventory, equipped weapons and armor, abilities, skill proficiencies, and languages — all tracked across sessions. Save your hero and carry them into a new campaign.
Balanced encounter scaling
26 monsters in the bestiary with challenge ratings. The engine scales encounters to your level — a level 1 warrior fights wolves and giant rats, not ancient dragons. Pacing controls prevent back-to-back combat or endless wandering.
Structured campaigns
Three full campaign templates with acts, NPCs, quests, and branching encounters. The GM knows the plot, advances the story based on your choices, and doesn't let you wander aimlessly. Shop for gear, craft items, rest to heal, and explore the world.
Free to play. Original CB20 game system — not affiliated with any existing tabletop RPG.
Where the platform is headed.
A roleplay platform is really four different products wearing the same interface. Most platforms pick one and are mediocre at the other three. Here's which pieces are live today, and which are next.
Chat, today
Create a character, set a scene, write. Streaming responses with a reasoning panel, your own model key if you want it. This part works now.
Prose controls
Adjustable narration density, point of view, tense — knobs that affect how the output actually reads, not just how it's branded.
Worlds & campaigns
Worlds, factions, and campaign state exist as entities separate from characters — so lore stays consistent. Full game mechanics are live in Dungeon Mode now.
A model router
Bring your own key for any OpenAI-compatible provider. Per-scene model selection is the next step; today you pick a default and switch when you want.
Pricing that respects power users.
Free stays free. Paid tiers add convenience and priority — and BYO key is a feature, not a downgrade.
