If you’ve ever been caught watching a video in a quiet waiting room, on the bus, or with your headphones already in playing something else — iOS 27 has just become very relevant to you.
Apple has announced a brand new feature called Generated Subtitles, and it might genuinely be one of the most useful things they’ve added to the iPhone in years.
What is Generated Subtitles?
Generated Subtitles will let your iPhone automatically create subtitles for any video you watch — that means subtitles for any video on social media, in the Photos app, in Messages, or anywhere else system-wide.
So whether it’s a TikTok someone sent you, a video your friend filmed on their iPhone, or something you’re streaming online — if it doesn’t already have captions, your phone will generate them for you automatically.
According to Apple’s press release: “While captioning solutions are increasingly common for users who are deaf or hard of hearing, subtitles for spoken dialogue are rarely available for personal videos, content shared by friends and family, and other media.” Generated Subtitles fixes that gap.
How does it work?
With on-device speech recognition, subtitles are generated privately — meaning the processing happens on your iPhone rather than being sent to a server — and appear automatically for uncaptioned videos on iPhone, iPad, Mac, Apple TV, and Apple Vision Pro. The appearance of the subtitles can be customised in the video playback menu or in Settings.
The privacy angle is worth noting. Everything is processed locally on your device, so your videos aren’t being sent anywhere.
Is there a catch?
One, for now. Generated Subtitles will initially only be available in English, and only in the US and Canada at launch. So UK iPhone users will need to wait a little longer — though as Apple Intelligence features have gradually expanded to more countries and languages over time, it seems safe to assume wider availability will follow.
Why this actually matters
Think about how often you watch a video without sound. On the bus. In bed. At work. In a café. The reality is that a huge proportion of video content is consumed silently, which is why so many creators already add captions manually. But user-generated content — voice notes, family videos, clips from friends — almost never has subtitles.
This feature makes all of that accessible. Not just for people who are deaf or hard of hearing, for whom this is genuinely transformative, but for every iPhone user navigating the very normal situation of wanting to watch something without disturbing the people around them.
When is iOS 27 coming?
WWDC — Apple’s annual developer conference where new software features are formally unveiled — is still a few weeks away. iOS 27 is expected to be announced there in full, with a public release typically following in September alongside new iPhone hardware.
Generated Subtitles is just one of a raft of new accessibility features Apple has previewed ahead of the event. If the rest of iOS 27 is this practical, it’s shaping up to be a very good update.
