Meta Smart Glasses ready

Bring smart glasses
to any iOS or Android app.

$ extentos=extend your app's capabilities

The smart glasses infrastructure for mobile apps. Your AI agent adds capabilities with Extentos and tests them in a browser simulator — no hardware needed. Bug fixes and improvements ship through our native library, so the smart-glasses layer stays current automatically.

Paste into any MCP-capable agent (Claude Code, Cursor, Windsurf, Cline). Restart the agent when it's done.
01 — architecture

Extends your agent.

Extends your agent's capabilities — while stripping maintenance and complexity, and making multi-vendor possible.

Extend your agent's capabilities.

Your agent gets 18 local MCP tools. We strip the complexity and optimize them for your agent.

  • Higher agent accuracy.
  • No SDK hallucinations.
  • Lower agent token cost.

Updates and fixes happen automatically.

New capabilities land for free, and Meta's SDK bug fixes apply themselves. No re-review marathons every time the vendor ships an update — the library absorbs breaking changes so your codebase doesn't have to.

  • New vendor features surfaced automatically.
  • SDK bug fixes and patches auto-applied.
  • Breaking changes absorbed by the library.
  • Zero re-review of your integration code.

Built for multi-vendor.

Meta Smart Glasses today. Whatever smart glasses we support next, your agent uses the same protocol for every capability — the library handles each vendor's details, and you can customize the experience per device when their hardware differs.

  • Meta Smart Glasses supported today.
  • Zero vendor SDK in your app code.
  • Customize per vendor when capabilities differ.
  • New glasses = library version bump, not a rewrite.
02 — test loop

Test in seconds. Ship to any vendor.

Your app runs in the same Xcode or Android Studio emulator you already use, connected to a browser Simulator your agent spins up and controls. The two work together end-to-end: whatever the Simulator sends — camera, mic, speaker — runs through your real app in the emulator, exactly as it would on physical glasses.

One fast loop — every platform.

Iterate in the browser — one run covers your whole target matrix.

  • Same code, verified on iOS and Android.
  • Every vendor reached through one protocol.
  • Seconds per loop — no device, no rebuilds.

Two testers: you and your agent.

The Simulator is built to be driven both ways.

  • You watch it live and click through the UI.
  • Your agent drives it through MCP.
  • One event log — read by both of you.

extentos = extend
your app's reach.

Install the MCP server. Point your agent at it. Ship to your first frames in an afternoon.
