How it scores

Usefulness
3/5

Tone rewrite in four styles from the keyboard (support.microsoft.com tone page); Android Authority found the AI features of little use and user reviews reports worse predictions.

Ease of use
4/5

Free on iOS and Android, tone tool is a two-tap flow, but needs Microsoft sign-in for AI and Android Authority took days to get used to it.

Value for money
5/5

Entirely free with no paid tier (microsoft.com/en-gb/swiftkey).

Privacy and trust
3/5

Typing data private unless shared, with a clear toggle and deletion controls (support.microsoft.com privacy page); Copilot data handling not explained on SwiftKey pages; 2016 leak resolved.

Momentum in 2026
3/5

Steady: SwiftKey Beta shipped an upgraded AI voice model (Android Police Sep 2026), but user and Unstar describe slowed development and declining quality; not in a16z's lists.

Verdict

SwiftKey is free with no paid tier, and its Copilot button can rewrite a message in four tones once a Microsoft account is signed in. Reviewers still rate its swipe typing and clipboard highly. Long-time users in user reviews say predictions and autocorrect have got worse since 2025, and Android Authority found the AI extras easy to switch off and not much use.

Best for

Android or iPhone users who want tone rewrites inside the keyboard at no cost

Skip if

People who only want accurate autocorrect, since long-time users report it getting worse

Ratings

What people say

Reviewers in 2026 still praise SwiftKey's swipe typing, multilingual typing and clipboard, but the user community says predictions and autocorrect have degraded, and some blame the move to generative AI. Store ratings (4.3 on Google Play from 4.6 million) sit well above that user reviews mood.

“Other than that, it's still the best I've found. The clipboard feature that allows you to keep phrases handy and insert them with 2 or 3 taps is incredibly time-saving”

Individual user review, 23 February 2026 · source

“It predicts words that don't exist, remembers your spelling mistakes, and doesn't correct obvious typos.”

Individual user review, 23 February 2026 · source

“I think the suggestion model has started using genAI instead of what they had before, it's getting worse on both platforms.”

Individual user review, 23 February 2026 · source

“Swiftkey went from one of the best keyboard apps to an enshittified shell of it's former self, in no small part thanks to AI.”

Press reviews

  • Android Police 2026-09-03

    Best pure typing of the three and its Copilot rewriting tools feel more practical than Samsung's Galaxy AI, but dated looks and clipboard sync hiccups left Gboard the winner.

  • Android Police 2026-09-05

    SwiftKey Beta replaced Gboard for the reviewer, with much faster, more accurate AI voice typing and multilingual swipe.

  • Android Authority 2026-01-24

    Higher ceiling than Gboard once its quirks are learned; the Copilot AI features weren't useful to the reviewer but are easy to turn off.

Privacy

Trains on your data
no by default for typing data: Microsoft says typing data stays private to the keyboard unless the user chooses to share it; Copilot features send text to Microsoft's Copilot service (SwiftKey pages do not describe that handling)
Opt-out
yes, Settings > Privacy > 'Help Microsoft to improve' toggle; remote and on-device data can be deleted under Account > Data settings
Retention
No general period stated; transaction records kept after account deletion 'by law'
Incidents
July 2016: cloud sync suggested other users' email addresses and phone numbers as predictions; SwiftKey disabled the sync and patched it. June 2015: vulnerability in the Samsung pre-installed version, fixed by Samsung (Wikipedia). None found since.
Age limit
UK App Store rating 4+, Microsoft account needed for AI features

FAQ

Is SwiftKey free?

How do I rewrite a message with SwiftKey?

Type or select the text, tap the Copilot icon, choose Tone, and pick Professional, Casual, Polite or Social Post. Then tap Replace (iPhone) or Accept (Android).

Does SwiftKey read what I type?

Microsoft says typing data stays on the keyboard unless the user opts to share it, and it does not learn from password fields. Text sent to the Copilot button goes to Microsoft's servers.

SwiftKey or Gboard?

Android Police's September 2026 month-long test picked Gboard overall for looks and voice typing, while rating SwiftKey best for prediction and swipe. Another Android Police reviewer switched to the SwiftKey beta for its improved voice typing.
