Utilize Your Hardware for Free AI
Scout is a local-first agent that runs air-gapped on your MacBook — chats, code, memories, and personal data stay on your machine instead of someone else's cloud. Write and ship code in Scout Code, run tasks on a schedule with Emissary, automate your filesystem, and connect the tools you already use — all from one workspace.
Scout runs on the same engine as the Courier API Platform — tool calling, flex models, analytics, OpenAI-compatible endpoints — but ships with a polished chat interface, OS workspace, and a personal-use license. The full API surface is there if you need it.
An Agent That Lives On Your Mac
Chat, write code, research, automate files, run tasks on a schedule, test APIs, and extend with MCP apps — all from a macOS-style workspace powered by Gemma 4 running locally on your Mac, or by Courier Cloud for the heavy models when you don't have the memory.
Agentic Chat Interface
Streaming conversations with tool calls, model picker, and modes for research, writing, and deep workflows.
Pathfinder Semantic Search
Indexes your home folder with embeddings and descriptions so Scout can find documents, code, and notes instantly.
Shadow Manager
Our novel sandboxing technology that protects your filesystem from agent mistakes. Everything the OS agent changes is staged in the Shadow Manager for your approval.
OS Agent
Scout can operate on your OS, navigating your filesystem, reading and writing to your desktop as a powerful agent — all safely thanks to Shadow.
MCPost API Testing
Import Postman or Insomnia collections and let Scout run, modify, and chain API requests agent-first.
MCP App Ecosystem
Connect MCP servers as first-class Scout apps alongside Assistant, OS, and Settings modes.
Settings Agent
A dedicated agent that can help you configure anything within Courier OS — models, integrations, preferences, and workspace setup.
A full coding workspace inside Scout
Scout Code is a complete Code Canvas — plan, edit, diff, run a terminal, and track todos all in one place. Agentic and safe by default, running on your Mac. You never have to leave Scout to code.
Plan mode
Scout drafts a risk-tagged plan you approve before it changes anything — destructive steps stay locked until you sign off.
Todos
A live checklist tracks every step of multi-part work, so long tasks stay legible from start to finish.
Diff viewer
Review exactly what changed — line by line — then promote it to your project or discard it. Nothing lands without your say.
File tree
Browse and navigate your whole project right inside the canvas.
Editor
Read and edit files in place, side by side with the agent doing the work.
Built-in terminal
A real WebSocket terminal wired into the canvas and sandboxed by Shadow — run commands without switching apps.
Send out an Emissary on Scout's behalf
Hand Emissary a task and a schedule, and it runs it unattended — then hands you the results. Set it and forget it; your Mac does the work.
Crash-safe by design
Every run persists its transcript as it goes, so nothing is lost if a task stops partway through.
Catches up on wake
Missed a run because your Mac was asleep? Emissary fires once on wake — never a backfill flood.
Runs one at a time
Scheduled runs execute single-flight, so local models never fight over your Mac's memory.
Ship Scout inside your product
Scout Embedded lets you drop Scout's interface — the Code Canvas, chat, and tools — straight into your own software, under your brand. A rock-solid, ready-to-go agent your users run locally on their Mac, without building one from scratch.
Embeddable UI
Drop the polished Scout interface into your app — no agent UI to design or maintain.
Your brand
White-labeled end to end. Your users see your product, powered by Courier under the hood.
Private & rock-solid
Runs on-device with Shadow safety, industry-leading tool calling, and hallucination detection built in.

Local or Cloud, One Click
Scout always runs locally on your Mac, but the models it calls can run either way. Use Gemma locally when your Mac has the memory, or route inference through your Courier Cloud tier — same agent experience either way.
Scout modes include Assistant for everyday chat, Scout Code for a full coding workspace, OS for filesystem automation, Collection for API specs, and Settings for configuration help — plus any MCP apps you connect yourself.
