Agentic Keyboard for iPhone: Apps, Privacy, and Setup
iPhone is where much of the agentic keyboard conversation is happening. iOS keyboard extensions, App Intents, and the growing on-device AI capabilities in newer iPhones create a foundation for keyboards that do more than type — they take action.
Acti (agentic) or Grammarly (writing)
iOS restricts third-party keyboard access
Full Access is optional but needed for AI features
Best iPhone Agentic Keyboard and AI Keyboard Apps
These apps support iOS and represent the current landscape of agentic and AI keyboards on iPhone. Each is tracked in our apps directory.
Acti is an emerging agentic keyboard that lets users perform cross-app actions directly from the keyboard interface. Instead of switching between apps, you can search, book, message, and complete workflows without leaving the current screen.
Best for: Mobile users who want to reduce app-switching and trigger actions from any text field
Wispr Flow turns spoken thoughts into formatted text in supported apps. iPhone uses a keyboard; Android uses a floating Flow Bubble alongside your existing keyboard.
Best for: Users who prefer voice input with AI-enhanced accuracy
Grammarly offers an iPhone keyboard and an Android floating writing assistant that works alongside your existing keyboard in supported apps. Features and setup differ by platform.
Best for: Professionals and writers who need polished text everywhere
Gboard provides predictive typing, Glide typing, voice input, and translation. Its newer proofreading and rewriting tools require a supported Android device and language; the Gboard app is not the Gemini assistant.
Best for: Everyday Android typing, multilingual input, and eligible-device writing tools
SwiftKey offers predictions, swipe input, and multilingual typing on iPhone and Android. Translator and Cloud Clipboard are Android features; availability differs by platform.
Best for: Personalized predictions, multilingual typing, and keyboard utilities
ChatGPT's mobile app increasingly functions as an AI agent — handling voice queries, web searches, and connecting to other apps through Shortcuts and APIs.
Best for: Users wanting a general-purpose AI agent on mobile
Perplexity's mobile app functions as an AI agent that can search the web, summarize content, and increasingly interact with other apps on your device.
Best for: Research-heavy users who need verified, cited answers on mobile
Apple Shortcuts combined with AI API calls and app intents enables custom agentic workflows — a build-it-yourself approach to mobile AI agents.
Best for: Power users who want to build custom agentic workflows
How to Enable a Third-Party Keyboard on iPhone
Installing a third-party keyboard on iPhone is straightforward, but the steps for enabling advanced features vary by app. Here's the general process:
- 1Download from the App Store. Find the keyboard app (Acti, Grammarly, SwiftKey, etc.) and install it like any other app.
- 2Go to Settings → General → Keyboard → Keyboards → Add New Keyboard. Find the keyboard you installed and tap it to add it to your active keyboards list.
- 3Grant permissions if prompted. Open the keyboard app itself first — many need initial setup before they appear properly in the keyboard switcher.
- 4Switch keyboards while typing. Tap and hold the globe/emoji icon in the bottom-left of the keyboard to switch between installed keyboards.
- 5Full Access (optional but often needed). For AI features like cloud predictions, voice input, or cross-app actions, you may need to enable Full Access. Go to Settings → [Keyboard Name] → toggle Allow Full Access. Read the keyboard app's privacy policy before enabling.
iPhone Privacy Checklist
Third-party keyboards on iPhone operate within Apple's privacy model, but agentic keyboards ask for more than standard keyboards. Here's what to check:
Full Access
Full Access allows a keyboard to communicate over the network. Without it, the keyboard is sandboxed — no internet, no cloud AI, no cross-app data. Many AI features require Full Access, but you can toggle it off anytime in Settings. If a keyboard works well enough without it, keep it off.
Calendar, Contacts, and Location
Agentic keyboards that execute actions (like booking or sharing your location) will request access to calendar, contacts, or location. Grant only what's needed for your use case. You can manage these permissions individually in Settings → Privacy.
Cloud vs. On-Device Processing
Check the app's description or privacy policy to understand where AI processing happens. On-device processing is more private; cloud processing may be more capable. Many apps use a mix — sensitive input stays local, complex queries go to the cloud.
Sensitive Text Fields
iOS automatically switches back to the default keyboard for secure text fields (passwords, credit card numbers). This is a system-level protection — third-party keyboards cannot access these fields even with Full Access enabled.

Agentic Keyboard vs. Siri, Shortcuts, and ChatGPT
iPhone already has several AI-powered tools. How does an agentic keyboard fit in?
Siri
Strength: Voice-first, hands-free, system-level access
Gap: Limited to Apple's ecosystem; can't act within third-party apps as flexibly as a keyboard
Apple Shortcuts
Strength: Powerful automation builder, integrates with App Intents
Gap: Requires pre-built automations; not spontaneous or context-driven during typing
ChatGPT app
Strength: General-purpose AI for research, writing, and analysis
Gap: Separate app — requires switching away from what you're doing. An agentic keyboard works inline
Agentic Keyboard
Strength: Always-available command surface, context-aware, reduces app switching
Gap: New category — fewer mature options, more permissions required
These tools aren't mutually exclusive. Using Siri for quick commands, Shortcuts for recurring automations, and an agentic keyboard for spontaneous cross-app actions is a practical setup that covers different needs.
