Give your NPCs a mind.
Cometforge characters remember your players across sessions, keep their word, and react to time — far past the old branching dialogue tree. Drop a component on a pawn, wire a few Blueprint nodes, done.
What the NPCs do
Characters, not chatbots.
A shared brain, a separate memory per character — the tavern keeper and the blacksmith are different people who remember you differently.
Persistent Memory
A 4-tier memory (working, episodic, semantic, procedural) with salience, decay, and consolidation — written crash-safe to disk so it survives a force-quit or power loss.
Kept Commitments
NPCs make promises and actually follow through later — “I’ll have it ready by morning” becomes a thing they remember and act on.
Temporal Awareness
Characters know that time has passed between visits and react accordingly, instead of resetting to zero every conversation.
Emotional Layers
Optional mood and relationship state that colors how a character responds to you — and how that shifts over time.
Character Authoring
Define a personality in a simple persona / Character file — quick to write, easy to iterate, no C++ required.
One Brain, Many Minds
The model is shared; each NPC keeps its own memory folder, so a whole cast runs off a single brain without bleeding memories.
Deployment
Runs your way.
Same C++ plugin, same Blueprint API — the editions differ only in where the brain runs.
Hosted API
Route dialogue to any OpenAI-compatible cloud model — Claude, OpenAI, Gemini, Mistral. Bring a key, no model bundled.
Your own server
Point it at your own local OpenAI-compatible server. Fully offline, your infrastructure, your rules.
In the packaged game
Embedded llama.cpp (Vulkan) runs a model right inside the shipped game. No cloud, no server, no per-call cost.
Services
AI at every layer of your game.
Cometforge is where it starts — but we integrate AI across your whole build, from concept to live ops, and we’ll develop custom models and training data tailored to your world. One system or a studio-wide strategy: we plug in at your level. Quoted pricing.
Design & Narrative
Ideation, worldbuilding, systems design, and branching story — AI as a force multiplier in pre-production.
Living Characters
NPCs with memory, commitments, and emotion. This is Cometforge — the anchor everything else builds around.
Gameplay & Simulation
Adaptive difficulty, AI directors, procedural quests and content, and simulated agents that make a world feel alive.
Production Pipeline
AI-assisted dialogue, localization, asset tooling, automated QA and testing, and internal copilots for your team.
Deployment & Infrastructure
Where the model runs — cloud, your own server, or fully on-device — tuned for cost, latency, and privacy. Our edge.
Hands-On Integration
Wiring AI into your engine (Unreal), model selection, fine-tuning, and optimization — done inside your codebase, not bolted around it.
Custom Models & Training Data
Bespoke AI models and training sets built specifically for your game and your world — not a generic model dropped in.
