The iPhone keyboard was the only game in town for six years, and it showed. Swipe typing arrived late, autocorrect still mangles names, and Apple's suggestion bar has never been ambitious. Third-party keyboards fill those gaps, and they've been allowed on iOS long enough that the survivors are polished, well-funded, and safe bets.
We picked three that earn their install: Google's feature-packed keyboard, Microsoft's prediction specialist, and Grammarly's writing assistant. Before any of them, though, you need to understand the permission they all ask for, because it's the single most important decision in this category. We'll cover it up front, not in a footnote.
The Full Access trade-off, up front
iOS runs third-party keyboards in a locked container by default: they can show keys and insert text, but can't touch the network. That sandbox makes many features impossible — cloud sync, learned predictions that follow you across devices, web search, GIFs.
So every keyboard in this roundup asks for Full Access, which removes the sandbox. With it, the developer's servers can technically receive everything you type. That's not a bug or a scare story; it's how the features work. Learned vocabulary has to live somewhere.
Our honest take: use Full Access keyboards for everyday typing — messages, notes, browsing — but not for passwords or banking codes. iOS also lets you switch back to the stock keyboard for sensitive fields with a long-press on the globe key. Compartmentalizing takes two seconds and closes the main risk.
Gboard: the feature-packed pick
Gboard is Google's keyboard, free, and the most loaded of the three. Swipe typing, voice dictation, emoji search, GIF search, translation as you type, and Google search built into the keyboard itself so you can look up and share an address without leaving the conversation.
If your question is "what can this keyboard do," the answer is more than any rival. It's also well maintained — Google ships updates constantly, and the swipe engine is among the best available.
The trade-off is the one you'd expect from a privacy-first site's perspective: the keyboard is Google's, the search runs through Google, and Full Access is required for the headline features. If you've opted out of Google's ecosystem deliberately, this keyboard quietly reopens the pipe.
SwiftKey: predictions that learn
SwiftKey is Microsoft's keyboard, free, and its specialty is prediction. It builds a language model from your actual typing style and gets noticeably better at finishing your sentences over weeks of use. Three-word suggestion rows, swipe input, and a clipboard bar built into the keyboard round it out.
That built-in clipboard deserves a mention: SwiftKey keeps a running copy history you can paste from in any app, which scratches part of the dedicated-clipboard-manager itch without a second install.
The trade-offs mirror Gboard's. Full Access is required for the learning features, and what it learns syncs through Microsoft's cloud. Prediction quality dips when you switch languages, and some people find the learned suggestions occasionally eerie in how personal they get. That's the feature working as designed — decide how you feel about it.
Grammarly: the writing assistant
The Grammarly Keyboard solves a different problem. Where Gboard and SwiftKey help you type faster, Grammarly helps you type better: grammar and spelling corrections, clarity suggestions, and tone hints applied across every app you type in. Free core checking, subscription for the deeper suggestions.
For email, work messages, and anything written for other people, having a second pair of eyes on every field is genuinely useful. It catches the mistakes autocorrect waves through.
The trade-offs: it's a heavier keyboard — slower to open, less fluid for pure speed typing — and the most valuable suggestions sit behind the subscription. As a daily driver, most people will prefer Gboard or SwiftKey. As a second keyboard you switch to when writing something that matters, it fits well. iOS makes switching between installed keyboards a one-tap affair, so carrying two is no burden.
Which one fits
- Most features, Google attached: Gboard. Search, GIFs, translation, great swipe.
- Predictions that know you: SwiftKey. Learning text engine plus a built-in clipboard.
- Better writing, not faster typing: Grammarly. Grammar help in every app.
And the stock keyboard remains a legitimate answer. If you don't swipe-type and write in short bursts, its privacy guarantees — no third party ever sees a keystroke — are worth more than any feature above.
