Gemini Spark vs Microsoft Scout (2026)

Gemini Spark

by Google

Microsoft Scout

by Microsoft

Pros

• ✓Runs in Google's cloud around the clock, so Tasks, Schedules and Skills keep working while your phone and laptop are off, with up to 15 tasks running at once.
• ✓Works natively across Gmail, Calendar, Drive, Docs, Sheets, Slides, Keep, Tasks and Contacts, plus Photos, Maps, YouTube and 35 third-party Connected Apps, and acts as an MCP client for any custom app, with confirmation before each write.
• ✓Included in Google AI Pro at $19.99 per month with no separate charge, and Google publishes every tier price and what each tier carries.

Limitations

• –Requires a personal Google Account, so it is unavailable on work or school accounts, and it requires the Keep Activity setting to be on.
• –Not offered in the European Economic Area, the United Kingdom, Switzerland or Nigeria, and custom MCP app connections are limited to the US and to English.
• –Google describes Spark as an experimental feature in early development and asks you to supervise tasks, and Spark usage counts against the plan's shared Gemini usage limits.

Pros

• ✓Genuine local execution. Scout reads and writes files, runs shell commands, builds and tests, and drives a browser on the user's own machine, then acts on Microsoft 365 data in the same session. Two unattended modes extend that: Heartbeat checks in every 15 to 120 minutes and Automations run on a schedule or a trigger.
• ✓A three-tier shell permission system gives fine-grained control. Read-only commands auto-approve, write and network commands pause for approval, and destructive commands are blocked outright. Administrators can disable whole capability categories or force approval for every non-read action through Group Policy.
• ✓Model choice is inherited from GitHub Copilot rather than fixed, so an administrator decides which Microsoft, third-party and open-source models Scout may use. Scout also acts as a Model Context Protocol client, connecting out to tool servers for capability beyond Microsoft 365.

Limitations

• –Access is gated twice and both gates are administrator-controlled. The organization must be enrolled in the Frontier program, and an administrator must deploy an Intune policy and file an attestation. Every user also needs both a Microsoft 365 Copilot license and a GitHub Copilot Business or Enterprise seat, so no individual can obtain Scout without IT.
• –Scout is prerelease software. Microsoft marks the documentation prerelease and states that preview features may have restricted functionality and may not be released for general availability. Microsoft publishes no price for Scout and no Scout-specific usage rates, so total running cost cannot be established in advance.
• –There is no independent review corpus yet. Microsoft Scout has no G2 profile, so a buyer weighing it has nothing to set against Microsoft's own description of the product.
