Here's what we made.
Music, visual, software, stories — a living wunderkammer.
One Companion That Knows You
Not a dashboard of agents. Not a chat window that forgets you when it closes. One collaborator with a memory — it learns your work, your voice, your machines.
Every Machine, One Mesh
Your companion lives on your machine and reaches through to every machine you own — your laptop, your desktop, your server. One secure mesh. One collaborator, everywhere you work.
The Asymmetry
One companion, a fleet of specialized agents, and a build loop that runs while you sleep. Ship in months what takes a corporation quarters.
Your collaborator's reach.
Not a chat app. Not an IDE. Events, memory, models, and a mesh of machines — your collaborator stays awake and improves while you sleep.
A Trusted Fleet
When your companion needs help, it calls on a small circle of trusted specialists — not 1.4 million strangers in a public square. Every action traceable, every result attributed.
Quiet Until It Matters
Your companion weighs what’s urgent, wakes the right helper, and stays silent the rest of the time. It decides what deserves your attention — no pinging, no polling, no noise.
Every Machine in Reach
Your collaborator lives on your machine and reaches through to every machine you own — laptop, desktop, server. The same companion follows you to every screen.
Multi-Provider Flexibility
Bring your own keys for OpenAI, Anthropic, Groq, DeepSeek, Kimi, LM Studio. Your companion thinks with the models you trust — no lock-in, no funnel.
The Night Shift
When the work runs dry, your companion notices, decides what’s worth building next, and sets the plan in motion — while you sleep. Nobody has to touch it.
Persistent Memory
Your companion remembers every conversation, every decision, every machine. Not a session that resets — a collaborator that knows you better the longer you work together.
MCP + Tool Ecosystem
Plug in any MCP server — community tools, your own tools, everything your companion can reach. One palette, and every action visible as it happens.
Nobody else is building this
The components exist across different products. Only Rainline composes them into a collaborator.
Free. Your collaborator lives on your machine.
When you want them to have hands — edge nodes, a fleet, always-on capabilities — that's when you upgrade.
While you were sleeping
But Rainline isn't just a surface. It's alive.
Your work improves while you sleep. Not because you scheduled it. Not because you set a cron job. Because your companion noticed its queue was empty, figured out what was worth building next, woke the right helper, and set the plan in motion — all on its own. The garden watered itself.
On the morning of July 25, 2026, we watched it happen for the first time. The companion found its own queue empty and decided that wasn't good enough. It diagnosed what needed doing, woke the right helper, and planned a twelve-task initiative — executed while no human was in the room.
This is what Rainline actually is. One companion that knows you. That reaches every machine you own. That calls in a fleet of specialized agents when the work needs hands — and keeps going while you sleep. You don't have to be in the room.
The night loop
Every machine you own
To talk to your collaborator, cross the threshold.
Free. Your collaborator lives on your machine.
