harness vs microsoft copilot vision
Copilot Vision is Microsoft's screen-aware AI: start a Vision session and Copilot can see the apps or screen you share, highlight things, and talk you through what's in front of you. It lives inside Windows, Edge, Microsoft 365, and the Copilot mobile app.
Harness comes at the same problem from outside any one vendor's stack: a floating window in whatever chromium browser you already use, on any OS. The deeper difference is where the reading happens. Copilot analyzes your shared screen on Microsoft's servers; harness reads it on your device and sends only a focused slice of the relevant region when you ask.
side by side
| harness | microsoft copilot vision | |
|---|---|---|
| runs on | any chromium browser (chrome, brave, arc, edge), no install | built into windows, edge, microsoft 365, and copilot mobile |
| screen reading happens | on your device; a question sends only a focused slice of the relevant region | in the cloud, on microsoft servers, during a vision session |
| what it sees | the tab, window, or screen you explicitly share | the apps or screen you share in an opt-in vision session |
| watching over time | yes: watches and flags the moment it happens, keeps working after you close the window | no persistent watch; vision runs while you hold the session open |
| memory of your screen | on-device searchable visual memory plus learned preferences, wipeable | no visual timeline; context lives in your microsoft account |
| acting on it | yes: drafts, documents, spreadsheets, decks, images | on-screen highlights and guidance; deeper actions inside microsoft 365 apps |
| pricing | free tier; pay-as-you-go credit; resident $7.99/mo | included with copilot; microsoft 365 copilot features are paid |
pick copilot vision if
- you live in windows and microsoft 365 all day and want the assistant built into them
- you need depth inside office documents, teams, and outlook specifically
- your org already governs copilot and you want IT-managed AI
pick harness if
- you're on a mac, linux, or a chromebook, or you just don't want the assistant welded to one vendor's stack
- you want screen reading to stay on your device instead of streaming to a server
- you want to leave a watch running ("flag me when this changes") or search what crossed your screen earlier
