Best AI Keyboard for iPhone in 2026
The best AI keyboard for iPhone depends on your main job: Grammarly Keyboard for writing quality, Wispr Flow for voice dictation, Acti for agentic cross-app actions, and Gboard or SwiftKey for free all-round typing. Your iPhone keyboard can do more than type — AI keyboards for iOS now offer grammar checking, tone adjustment, voice dictation, and even cross-app actions. Here is how to pick the right one for your needs.
Which AI Keyboard Should You Choose?
Pick your primary need and start with the recommended app. Each recommendation includes category, maturity, and pricing tier so you can decide quickly.
Industry-leading grammar, tone, and clarity checking inside every iPhone app. The most mature AI keyboard for polished writing on iOS.
AI-powered voice dictation that formats and cleans up your speech into polished text. Works across any app on iPhone.
The closest thing to a true agentic keyboard on any platform. Executes cross-app actions — search, book, share — from the keyboard on iOS.
Solid free keyboards with swipe typing, translation, and smart prediction features where supported. Gboard fits Google users; SwiftKey fits Microsoft ecosystem users. Both support iOS.
Powerful AI assistants for research, drafting, and analysis. They run as separate apps — not keyboard replacements — but pair well with any AI keyboard.
How to Choose on iPhone
Picking an AI keyboard for iPhone involves trade-offs that are specific to iOS. Here are the key constraints to keep in mind.
Full Access is often required
Most AI features — cloud predictions, voice dictation, web search, cross-app actions — need Full Access to be enabled. Without it, the keyboard is sandboxed and cannot connect to the internet. You can toggle Full Access on or off anytime in Settings, and iOS automatically uses the default keyboard for password and other secure fields regardless of your setting.
Third-party keyboards have less power on iOS than Android
iOS restricts what third-party keyboards can do compared with Android. System-level automation, deep app integration, and background processing are more limited. This means agentic keyboard features — cross-app actions, context awareness, autonomous workflows — are harder to deliver on iPhone. If you have both platforms, you may find more capable AI keyboard features on Android.
Secure fields are protected automatically
iOS automatically switches back to the default keyboard for secure text fields, such as passwords and similar sensitive inputs. Third-party keyboards cannot access these fields even with Full Access enabled. This is a system-level protection you do not need to configure.
Switching between multiple keyboards is easy
Tap and hold the globe icon (or emoji icon) in the bottom-left of the keyboard to switch between installed keyboards. A common setup: Grammarly for work email and writing, Wispr Flow for dictation, and the default iOS keyboard for quick messages and sensitive fields. You can configure which keyboards appear in Settings → General → Keyboard → Keyboards.
Pricing varies — check listings before installing
Some keyboards are fully free (Gboard, SwiftKey). Others are freemium with paid tiers for advanced features (Grammarly, Wispr Flow). App Store listings show current pricing and in-app purchase details. Plans and pricing can change, so always verify on the official App Store page before committing to a subscription.

Full reviewAI Keyboard, Agentic Keyboard, or Mobile AI App — What is the Difference on iPhone?
AI Keyboard
Improves text — grammar, tone, predictions. Works inside every app as a keyboard replacement.
Grammarly, Gboard, SwiftKey
Agentic Keyboard
Executes tasks — search, book, share — from the keyboard. Still emerging, especially on iOS.

iOS Privacy and Full Access
Most AI keyboard features on iPhone require Full Access — a permission that allows the keyboard to communicate over the network. Without it, the keyboard is sandboxed. Always review what data a keyboard processes on-device vs. in the cloud before enabling Full Access. iOS automatically switches to the default keyboard for password and other secure fields.
