AI agents should
show their work.
Saturday.ai is a local-first agent platform. Every plan, tool call, metric, and decision is written to the screen as it happens — on your hardware, in your terminal.

The terminal is the product.
Saturn is Saturday.ai's terminal-based, local-first agent. It surfaces everything: the plan it generates, the tools it calls, the approvals it waits on, and the system it runs on. No hidden steps, nothing leaves your machine.

02Philosophy
Five non-negotiables.
Every design decision in Saturday.ai traces back to one of these.
01
Local First
Models, context, and data stay on your machine. No round-trips to a vendor, no telemetry you didn't opt into.
02
Transparency
Plans, tool calls, and reasoning are written to the screen as they happen — not summarized after the fact.
03
Observability
Token usage, latency, memory, and execution traces are exposed as first-class, inspectable system state.
04
Extensibility
Add tools, integrations, and workflows over time. The agent grows with your stack instead of boxing you in.
05
Control
Approval gates sit in front of every side effect. The agent proposes; you decide what it's allowed to do.
03Capabilities
Everything the agent does, in the open.
A focused set of primitives — not a sprawling feature list. Each one is observable and under your control.
[llm]
Local LLM support
Run open models on your own hardware. Bring your weights; nothing leaves the machine.
[inspect]
Workflow inspection
Step into any plan and see the exact sequence of decisions that produced it.
[gates]
Tool approval gates
Every side effect pauses for review. Approve, deny, or inspect the diff before it runs.
[metrics]
Live metrics
Tokens, latency, throughput, and memory stream live as the agent works.
[rag]
RAG document ingestion
Index local files and feed grounded context to the agent without a cloud pipeline.
[extend]
Extensible architecture
Register custom tools and workflows through a small, typed interface.
[tui]
Terminal-first experience
A keyboard-driven TUI built for developers who live in the terminal.
