Greenstone.
Introducing the world's most sustainable AI — a.k.a. your new best friend.
A decentralized AI companion that lives close to you. Preloaded with local, offline, open-source models, it connects your tools so you can skip massive datacenters — and runs fully off-grid when you need it to. Currently in Alpha.
Most AI tools want you to use
Greenstone helps you use just enough.
Connect tools, skip the datacenter
Greenstone helps you wire up calculators, scrapers, scripts and local tools — so a 7B model on your laptop can do work that would otherwise spin up a data hall.
Preloaded with local models
Ships with curated, open-source, offline-first models. No accounts, no keys, no telemetry. It just runs.
100% off-grid, fully autonomous
Pair it with an ePod and a Freebird mesh node and Greenstone keeps thinking when the wider grid does not.
Wire your chats together.
Open as many local, web, or Greenstone chats as you like and connect them with quiet little green wires. Context flows. Tools flow. Automations flow. No dashboards, no noise — just a calm, decentralized mesh of conversations on your own desk.
- ◆ Share memory between chats with a single thread.
- ◆ Pipe outputs from one model into another's tools.
- ◆ Run agents that watch, summarize, or escalate.
Build a Molecule.
Polish it into a Kairnel.
Save your favourite automations as Molecules — small, shareable bundles of models, tools, and prompts. When a Molecule earns its keep, condense it into a hyper-minimalist Kairnel stone for the Kairn orchestrator — stackable, legible, and quiet as a cairn on a trail.
Meet your stone.
We're slowly opening the Alpha. Field-testers, researchers, and quiet builders welcome.
