“Smart” on an air fryer can mean four different things: an app that starts and monitors a cook, a voice assistant link, a voice system that works offline, or a probe that reads the temperature of the food. They are very different features, and most cooks use none of them every day.
The six models below cover those four meanings. Every detail comes from the product listing, and we have not used these machines ourselves. App and assistant support can change after a listing is written, so check the product page and the maker’s app notes before you buy.

Is Smart Worth It?
- Yes if you like guided recipes, want to start a cook from another room, or want a probe.
- Probably not if you cook the same few foods and know the settings.
- Consider: an app is another account, another permission and another update to manage. Read the privacy notes.
Power and Circuits
These models list 1,500 to 1,725 watts. A standard 15 amp, 120 volt circuit tops out around 1,800 watts, so keep other high-wattage appliances off the same circuit.
Mistakes to Avoid
- Paying for connectivity you will not use.
- Ignoring the network and account setup that apps need.
- Assuming every “smart” label means an app; some mean a thermometer.
- Skipping the manual care notes on the basket coating.
Smart Air Fryer FAQ
Do I need WiFi?
Only for app-based models. The Emerson listing says its voice control works offline.
Does it work with Alexa or Google Assistant?
The COSORI Pro Smart and Pro Gen Smart listings say yes. Check the product page for current support.
Is a thermometer better than an app?
They solve different problems. A probe tells you when food is done; an app lets you start or monitor a cook.
The Short Version
For voice and app together, the COSORI Pro Smart. For app control and a stainless exterior, the COSORI Iconic. For offline voice, the Emerson SmartVoice. For doneness probing, the Ninja Foodi DZ550.
