Extentos is a useful idea for developers who want to add smart-glasses features without building everything from scratch. The platform looks promising, but it may take some time to get familiar with the tools and workflows. It could be limiting for developers who need complete control over every detail, but for faster prototyping and testing, it seems like a practical solution.

Extentos is a multi-vendor development platform for adding smart-glasses capabilities to iOS and Android apps, including real-time voice assistant that runs on the model you choose, from cloud models to local models that cut your AI costs. An AI agent wires it into your app, a browser simulator lets you test it without hardware, and analytics show how it runs on real glasses. The simplest analogy is Stripe for smart glasses

AI Agents

Extentos adds multi-vendor smart-glasses capabilities to iOS and Android apps with a simulator, AI agent and analytics.

Key features

5 features of Extentos

MCP Server — Drives full integration from code to a running app using a coding-agent aware of all APIs.
SDK — Native iOS (Swift) and Android (Kotlin) SDK, vendor-agnostic, available via Swift Package Manager and Maven Central.
Simulator — Browser-based emulator that behaves like real glasses, enabling testing without hardware.
Agent Runtime — Configurable voice assistant runtime supporting multiple models (Claude, GPT, Gemini, local) and voices.
Analytics — Collects error, latency, frame-drop and usage metrics from real glasses deployments.

Use cases

Add camera capture and other glasses APIs to an existing mobile app with a single SDK call.
Iterate on smart-glasses UI/UX in a browser simulator before purchasing hardware.
Deploy a custom voice assistant on glasses using a chosen cloud or local LLM.
Monitor real-world performance and failures of glasses features across vendors.

Extentos vs Fine: Fine focuses on building software with AI agents, not on smart-glasses integration.
Extentos vs Unified MCP Server: Unified MCP Server provides a generic tool catalog, while Extentos offers a specialized smart-glasses SDK and simulator.
Extentos vs luoluoAI: luoluoAI aggregates model endpoints, whereas Extentos provides end-to-end glasses integration and testing.
Extentos vs SuperAGI Cloud: SuperAGI Cloud runs autonomous AI agents in the cloud; Extentos runs the agent locally or in the cloud specifically for glasses.
