Does Apple Intelligence Writing Tools work with a third-party keyboard on iPhone?
Writing Tools hangs off the text you select, not off the keyboard that typed it, so it shows up the same way no matter which keyboard is active. Why that makes it the opposite case from Genmoji, what actually turns it off, and where Full Access does and does not fit in.
You select a paragraph you just typed, the usual popup offers Copy and Look Up, and this time there is also a Writing Tools option sitting among them. It is a fair thing to wonder about, especially once you already know that Genmoji only comes from Apple’s own emoji keyboard: does Writing Tools have the same requirement, and does it disappear the moment you switch to a keyboard you installed yourself? It does not, and the reason is almost the mirror image of the Genmoji answer.
What Writing Tools actually is
Writing Tools is part of Apple Intelligence, reachable by selecting a piece of text and choosing it from the same popup menu that already offers Cut, Copy, Paste and Look Up. From there it can proofread the selection, rewrite it in a different tone, or summarize it, using a model built into iOS rather than anything typed by a third party. It needs Apple Intelligence turned on — in Settings, under Apple Intelligence & Siri — and, like the rest of Apple Intelligence, it is not available on every iPhone or in every language and region, independent of any keyboard question at all.
Why it does not care which keyboard is active
Writing Tools is not a button that lives inside a keyboard’s own interface the way Genmoji’s creation button lives inside Apple’s emoji panel specifically. It hangs off the text itself, through the same selection menu that offers Copy and Paste on any text view, in any app, no matter which keyboard happens to be on screen at the time — or even if no keyboard is on screen, because the field is not currently being typed into at all. A keyboard extension draws the keys and, on some keyboards, a suggestion bar above them; it has no part in drawing the selection handles, the popup menu, or the panel Writing Tools opens once you tap into it. Because the feature is attached to the text view rather than to the keyboard, swapping Apple’s keyboard for a custom one changes nothing about whether the option shows up.
The opposite shape of restriction from Genmoji
Genmoji is walled off behind one specific keyboard’s interface, so no other keyboard can offer it, which is exactly the kind of boundary that makes “does this work with my keyboard” a real question with a real no attached. Writing Tools was built the other way around: it sits above the keyboard layer entirely, attached to the text field rather than to whatever is currently drawing the keys underneath it. A restriction tied to one keyboard’s UI and a feature tied to the text view itself land on opposite answers to the same kind of question, and it is worth knowing which shape a given iOS feature actually has before assuming a custom keyboard is the reason something is missing.
What actually turns the option off
- Apple Intelligence switched off in Settings, or a device that does not support it at all.
- A language or region Apple Intelligence does not yet cover — this is a coverage limit on the feature itself, not on any keyboard.
- A secure text field, such as a password box — the same override that hands the keys themselves to Apple’s keyboard also keeps the selection menu from offering anything beyond the basics there.
- A selection too short, or a field the app itself has opted out of offering the feature in — a decision the app made about its own text view, not one a keyboard has any say over.
None of those reasons involve which keyboard typed the text or which keyboard happens to be active when you go to select it. If Writing Tools is missing, one of the items above is almost always why, and swapping back to Apple’s keyboard to test does not change any of them.
It has nothing to do with a keyboard’s Full Access switch
It is a reasonable guess that a system-level writing feature ties into the one permission iOS keeps asking a keyboard about, but Full Access governs a keyboard extension’s own access to the network and the system clipboard, not a system feature that runs above the keyboard layer entirely. Writing Tools reads the text already sitting in the field through the app’s own text view, the same way Copy and Paste do, and a keyboard with Full Access left off shows the exact same Writing Tools option as one with it turned on.
Where Kibo fits
Text typed with Kibo — in any of its 56 themes, with any of its 17 key sounds, in any of its 30 languages — is ordinary text sitting in the field the moment it lands there, no different from text typed with any other keyboard. Selecting it and reaching for Writing Tools works exactly the same way, because Kibo, like any keyboard extension, has no part in drawing the selection menu or deciding what appears in it. None of this touches Full Access, which Kibo reads only for the Copy word, Copy line and Paste buttons on its own toolbar. Kibo is free to download.
Frequently asked questions
Do I need Apple’s own keyboard to use Writing Tools?
No. Writing Tools is reached by selecting text and choosing it from the popup menu that also offers Copy and Paste, and that menu works the same way regardless of which keyboard is currently active or which keyboard typed the text in the first place.
Is this the same restriction as Genmoji not working with a third-party keyboard?
No — it is the opposite shape. Genmoji’s creation button is built into Apple’s own emoji keyboard specifically, so no other keyboard can offer it. Writing Tools is attached to the text field itself rather than to any keyboard’s interface, so it shows up the same way no matter which keyboard is active.
Does a keyboard need Full Access for Writing Tools to appear?
No. Full Access governs a keyboard extension’s own network access and its reach into the system clipboard. Writing Tools runs above the keyboard layer entirely, reading the text through the app’s own text view, so it appears the same way whether Full Access is on or off.
Why is Writing Tools missing even though I selected text?
Check whether Apple Intelligence is turned on for the device, whether your language and region are covered, and whether the field is a secure one such as a password box. All three are coverage or field-level limits on the feature itself, not something caused by any particular keyboard.
