Detailed Breakdown
An honest look at the pros and cons of each smart home AI assistant.
On-device AI • Open source • Free
Agenthing is the first on-device AI assistant designed entirely for the smart home. All processing happens locally on hardware you already own — your phone, laptop, or a mini PC. No cloud dependency, no subscription fees, and no listening third parties.
Cloud-based • Ecosystem locked • $3.99/mo+
Amazon Alexa is the most widely adopted smart home assistant with the largest skill ecosystem. However, it requires always-on cloud processing, a dedicated Echo device, and an Amazon account. Voice recordings are analyzed for ad targeting and product recommendations.
Cloud-based • Data-mining • Free*
Google Home (powered by Google Assistant) integrates deeply with Google services and has excellent natural language understanding. But like Alexa, it's cloud-dependent and processes your voice through Google's servers — where it's used to train models and serve targeted ads.
Hybrid processing • Ecosystem locked • Free*
Apple Siri offers better privacy than Alexa or Google Home — some processing happens on-device, and Apple doesn't sell user data. However, complex requests still hit Apple's servers, Siri is limited to Apple devices and HomeKit accessories, and its smart home ecosystem is the smallest of the four.
Privacy Comparison
Every other assistant sends your voice to the cloud. Agenthing never lets it leave your home.
Pricing Comparison
The hidden costs of cloud assistants add up fast. Here's the real picture.
The Verdict
When you add up the cost, privacy risks, and limitations of cloud assistants, the choice becomes clear.
With Agenthing, the AI model, your voice data, and your automations live on your hardware. No company can revoke access, change the terms, or shut down the service. Compare that to Alexa, where Amazon controls the entire experience.
Cloud assistants lock you into recurring fees for basic features. Agenthing is free to start and always will be. No credit card needed. No surprise bills.
Internet goes down? That's fine. Agenthing keeps running locally. Alexa, Google Home, and Siri all stop working — or become severely limited — without connectivity.
Alexa pushes Amazon products. Google Home pushes Google services. Siri works only with Apple. Agenthing is brand-agnostic — it connects to Samsung, Govee, Philips Hue, Roku, Sonos, and thousands more through Home Assistant.
