Does Live Translation in Messages work with a third-party keyboard on iPhone?
Live Translation reads the message sitting in the compose field the moment you hit send, not the keyboard that put it there, so it treats a custom keyboard exactly like Apple’s own. Where the feature actually lives, what turns it off, and why it is a different job from typing in one of Kibo’s 30 languages.
You turned on Live Translation for a conversation with someone who writes in a language you do not, typed your reply the way you always do — same theme, same key sounds, same keyboard you installed instead of Apple’s own — and now you are wondering whether the translation will actually go through, or whether this is one of those Apple Intelligence features that quietly expects its own keyboard in front of it. It works the same either way, for a reason that keeps coming up with Apple Intelligence features on this site: what decides the answer is where a feature reads its input from, not which keyboard put it there.
Where Live Translation actually lives
Live Translation is part of Apple Intelligence. You turn it on per conversation, not once for the whole device: open a thread in Messages, tap the contact’s name at the top, turn on Automatically Translate, and choose a language under Translate From. The languages involved need to be downloaded to the device first, since translation runs on-device rather than over a network connection. Once it is on, a reply is translated as you type it, and tapping send delivers both your original wording and the translated version, with a small “Translating” indicator you can tap to choose which one you see on your own end of the conversation.
The same Apple Intelligence feature also shows up as live captions in FaceTime and as a spoken translation on phone calls, and can work over AirPods for an in-person conversation. None of those involve typing at all, which is why the rest of this page sticks to the Messages case — the only one where a keyboard is actually part of the picture.
Why it does not care which keyboard typed the message
A keyboard extension’s job stops at inserting characters into the ordinary text field Messages already provides for composing a reply — the same field any keyboard, Apple’s included, types into. Live Translation reads the contents of that field, the same way Send and the character counter already do, and translates whatever is sitting there once you tap send. None of that machinery asks which keyboard put the characters there, only that they are there. Switch keyboards mid-conversation and Live Translation keeps working exactly the same, because a compose field full of text looks identical to it regardless of which keyboard filled it.
The same shape as Writing Tools, not the shape of Genmoji
A separate guide on this site covers why Apple Intelligence Writing Tools works the same on text typed with any keyboard, because it hangs off the text view itself rather than off the keyboard’s own interface — and why that is the opposite of Genmoji, which lives inside Apple’s emoji keyboard specifically and genuinely does disappear on a custom one. Live Translation has the same shape as Writing Tools: it is attached to the message you are composing, not to whatever is drawing the keys underneath it, so it lands on the same answer.
What actually turns it off
- Apple Intelligence switched off in Settings, or a device that does not support it — a hardware and software requirement with nothing to do with which keyboard is installed.
- The conversation’s own Automatically Translate switch left off, or no language chosen under Translate From — both set per conversation, not once for the whole device.
- A language pair Apple Intelligence does not yet cover in the current iOS release, the same kind of coverage limit already covered on this site for Writing Tools and for Kibo’s own typing languages.
- The languages involved not yet downloaded to the device, since translation runs on-device rather than fetching anything mid-conversation.
None of those reasons involve which keyboard is active while you type the message, and switching back to Apple’s keyboard to test will not change any of them.
It has nothing to do with a keyboard’s Full Access switch
Full Access governs what a keyboard extension itself can reach — mainly the system clipboard, on a keyboard that offers its own copy or paste buttons. Live Translation is not something a keyboard extension does at all: it is Messages reading its own compose field and calling into Apple Intelligence, a step that happens entirely outside the keyboard, whether Full Access is on, off, or the keyboard has never asked for it in the first place.
Not the same job as typing in the language directly
It is worth separating this from Kibo’s own 30 typing languages, three of them composed, which are about producing the words yourself, letter by letter — hangul jamo assembling into Korean syllables, romaji becoming Japanese kana, pinyin offering Chinese characters. Live Translation does a different job entirely: it takes a message written start to finish in one language and hands the recipient the same message rewritten into another, without you typing a single character of that second language yourself. One is a way to write in a language; the other is a way to avoid needing to. They sit in the same conversation without conflict — write your reply in your own language with whichever keyboard you are typing on, and Live Translation carries it the rest of the way into a language you never touched.
Where Kibo fits
Kibo inserts text into the Messages compose field the same way any keyboard does, a character at a time, into the same standard field Live Translation already reads from the moment you hit send. None of Kibo’s 56 themes, 17 key sounds or 30 typing languages change what lands in that field, so a message typed with Kibo translates exactly as one typed with Apple’s own keyboard would. None of this touches Full Access, which Kibo reads only for the Copy word, Copy line and Paste buttons on its own toolbar. It is free to download.
Frequently asked questions
Do I need to switch to Apple’s own keyboard for Live Translation to work?
No. Live Translation reads the message sitting in the Messages compose field once you tap send, not the keyboard that typed it. A keyboard’s only job is inserting characters into that field, so a custom keyboard is treated exactly the same as Apple’s own.
Does my keyboard need Full Access for Live Translation to work?
No. Full Access governs what a keyboard extension itself can reach, mainly the system clipboard. Live Translation is Messages reading its own compose field and calling into Apple Intelligence, a step that happens entirely outside the keyboard regardless of that switch.
Does the other person see what I actually typed, or only the translation?
Both. Tapping send delivers your original wording along with the translated version, and a small indicator lets you choose which one you are looking at on your own end of the conversation.
If Kibo already types in 30 languages, why would I need Live Translation too?
They solve different problems. Kibo’s languages let you type your own words directly in Korean, Japanese, Chinese and the rest. Live Translation takes a message you wrote in one language and rewrites it into another for the recipient, without you typing any of that second language yourself.
