Choosing ai assistants for mobile
Do mobile AI assistants work offline?+
Most need a connection; a few run smaller models on-device for basic tasks. Check the offline claims against your real use.
Can they read my screen?+
Some can with permission. Treat screen access as sensitive and enable it only for tools you trust.
