AI NPCs & companions
Hearthkeepers
NPCs that remember your players. Companions that fight beside them.
Most server NPCs are vending machines. Hearthkeepers makes them characters. The blacksmith remembers who sold him stolen iron. The guard warms to you over a week of good behaviour. And every player gets a companion that walks out the gate with them — to fight, talk, and run quests. No setup, no API keys — install it and it just works.
Characters, not chatbots
No setup, no API keys
No GPU to run, no keys to manage, nothing to prompt. Drop in the jar, add your license, and your NPCs are alive.
Full model on every tier
Free runs the same Qwen3-235B as Network. Paid tiers buy headroom, not a better brain — you're limited on how much you use, never on quality.
Memory that sticks
An NPC remembers players by name and by what they did — for weeks, not just inside one conversation. Relationships build, or sour, over real time.
Everything it does
- Characters, not chatbots — free-text conversation kept to clean one- or two-line replies.
- Persistent memory: an NPC recalls who a player is and what they did, session after session.
- Mood and a relationship that climbs from stranger to ally — or sours, if a player earns it.
- Per-player companions that follow you out the gate to fight, talk, and take on multi-step quests.
- The full-strength model on every tier, Free included — you're capped on volume, never quality.
- No GPU, no API keys, no prompt-writing — install the jar, add your license, and it works.
Hearthkeepers pricing

How metering works
1 credit = 1 chat message · 1 companion agent goal = 40 credits
You're metered on credits, not raw messages, so a big quest can't be under-counted. Caps are denominated in credits, which keeps every tier predictable.
