The AI agent that flies. Faster, lighter, more effective, and a joy to use.
Up and Running in Seconds
Copy and paste the install command in your terminal
$ curl -fsSL https://nctrnl.dev/install | bash
## Terminal
State of the art teriminal experience
Terminal first design; blazingly fast, image capable, mouse-driven, and keyboard-first.
## Desktop
A desktop app with a modern style
Nocturnal on the desktop: easily manage sessions and config using the same fast agent backend
Rechable everywhere
Reach your agents from the terminal, the desktop, or from Telegram or Discord. Your agents are accessible from any surface.
Persistent memory
Learns your preferences and workflow over time, auto-generates skills. Memory and skills can keep improving in the background without any explicit setup.
Focused automation
Natural-language scheduling for reports, backups, and briefings — running unattended through the agent runtime. Ask the agent to plan recurring tasks and let them work while you sleep.
Shapes itself to fit
Use any of 50+ providers and switch models mid-session, with cache-preserving round-robin and failover for uninterrupted overnight execution. Multi-agent native: agents work in parallel and communicate via a built-in messaging system.
Secure key storage
Tools run in isolated sandboxes. Provider API keys are inaccessible to agents on disk and in the environment unless you allow, making it impossible for agents to leak/exfiltrate them.
Long-horizon agents
A real plan agent consults for high-quality planning, automated reviews catch mistakes before you see them, and checklists force agents to keep working until approved by adversarial review.
## Performance
Every millisecond you wait is a millisecond you're not building something great
Nocturnal starts in less than 13ms (that's 10x faster than human perception) and uses less RAM and CPU than any other agent, while at the same time providing the best user interface. Check out these measurements:
## Speed
Startup Time
Cold start to ready for input. Lower is better. (Intel Core Ultra 7)
## Efficiency
Memory Usage
RSS + swap at idle post-start. Lower is better.
