AI Subtitles on a Mac: What Actually Works Right Now

VLC demonstrated offline AI subtitles at CES in January 2025: real-time transcription and translation in more than 100 languages, running locally, with nothing sent to a server. Twenty months later it still has not shipped. As of 11 September 2026, the version VideoLAN serves from its own download page is VLC 3.0.23, for Apple silicon and Intel Macs alike. There is no VLC 4.0 download, and the subtitle feature is tied to VLC 4.0.

That gap has left a strange hole in the search results. Half the pages you find are announcement coverage frozen in January 2025, still written in the future tense. The other half are subtitle websites that want you to upload your video to them. Almost nobody mentions the thing sitting in your System Settings right now, which captions audio on device, costs nothing, and is about to get considerably better. This is what actually works on a Mac today, what arrives with macOS 27, and where each option falls down.

The Key Takeaways

• VLC still has not shipped AI subtitles: announced at CES 2025, tied to VLC 4.0, and VideoLAN's download page still serves 3.0.23 with no release date ever announced.
• Your Mac already captions live audio: Live Captions transcribes anything playing through your Mac, but only on Apple silicon.
• macOS 27 adds the missing piece, in two countries: Generated Subtitles caption video that has no captions, on device, including video streamed online, but Apple says English, in the US and Canada.
• Every cloud subtitle tool wants your file: VEED, Submagic, Kapwing and the rest all work by uploading your video to them.
• Apple publishes a limit nobody else does: accuracy "may vary and should not be relied upon in high-risk or emergency situations".

When Will VLC AI Subtitles Be Available?

VLC demonstrated offline AI subtitles at CES 2025 on 9 January, but as of September 2026 the feature has still not shipped to the public. It is tied to VLC 4.0, which has not been released, and VideoLAN has never announced a release date. The current download on VideoLAN's own site is version 3.0.23.

What VLC actually demonstrated

At CES 2025, VideoLAN president Jean-Baptiste Kempf showed VLC generating subtitles for a video with no subtitle track, then translating them live into another language. The processing happened on the machine. No account, no upload, no connection required after setup.

The engine is whisper.cpp, a C implementation of OpenAI's Whisper speech recognition model. That detail matters more than it sounds. It is the same family of technology behind most of what now runs locally on consumer hardware, and it is the reason the feature could plausibly be offline at all.

Why it is stuck

The feature was never planned for the version you are running. It belongs to VLC 4.0, a release that has been in development for years and has reshaped the player's internals. VLC 4.0 has reached beta and nightly builds, but it is not the version VideoLAN gives the public, and until it ships, neither do the subtitles.

VideoLAN's own news page makes the timeline unusually clear. It shipped 3.0.23 on 8 January 2026, a maintenance release of the old branch, and three weeks later, on 31 January 2026, announced it would be at FOSDEM showing "our AI based live subtitles generator". So the feature exists, it is still being demonstrated, and it is still not in anything you can download. That has been the pattern for twenty months.

This is where the search results become actively unhelpful. Some pages, all of them written around the CES demo, describe the feature as though it were imminent or already available. Others say it is still missing. Both kinds of page are still ranking, and the reader gets no straight answer. The straight answer is the download page: 3.0.23, no 4.0, no date.

Your Mac Already Has AI Subtitles Built In

While VLC's feature has been pending, Apple quietly shipped most of it. Live Captions transcribes audio on your Mac in real time and displays it in a floating window, and it has been there for several macOS releases.

How to turn on Live Captions

Apple's instruction is exact: choose Apple menu, then System Settings, click Accessibility in the sidebar, then click Live Captions. The first time you switch it on, language data downloads to your Mac, so you need to be connected for that initial step. After that the transcription itself happens on the machine.

The setting most people miss is the source toggle. Apple's own support documentation describes a microphone control in the Live Captions window that switches between your Mac's audio output and its microphone input. The output setting is the one that matters here: it captions anything playing, in any app. A video in Safari, a film in VLC, a podcast, a FaceTime call.

The two limits that matter

The first is hardware. Apple states that Live Captions "is available only on Mac computers with Apple silicon and is not available in all languages, countries, or regions". If you are on an Intel Mac, this option does not exist for you, and no setting will produce it. Given that macOS 27 drops Intel Macs entirely, that line is only going to get firmer. Our guide to which Apple devices support Apple Intelligence covers where the hardware cutoffs fall.

The second is accuracy. Apple is unusually blunt about it: "The accuracy of Live Captions may vary and should not be relied upon in high-risk or emergency situations." No subtitle website on the first page of Google publishes a caveat like that. Several advertise accuracy figures above 99 percent instead. Treat live transcription as a strong aid and a poor record, particularly with overlapping speakers, heavy accents or music underneath dialogue.

What macOS 27 Adds: Generated Subtitles

Live Captions has one real weakness. It captions audio as it plays, which means it works on live sound but does nothing useful for a video file you want subtitled properly. That is the gap Apple is closing.

Announced on 19 May 2026, Generated Subtitles produce transcriptions for video that has no captions of its own. Apple's wording is specific about the scope: subtitles appear "automatically when captions or subtitles are not already provided, including in clips recorded on iPhone, received from friends and family, or streamed online". They are generated with on-device speech recognition, and Apple names the platforms plainly: iPhone, iPad, Mac, Apple TV and Apple Vision Pro.

Two things make this the most significant item on the list. It covers streamed video, not just files sitting on your disk, and it runs privately on the machine rather than uploading anything. That is close to what VLC promised at CES, arriving from a different direction and on a shipping timetable. Apple's stated timing is "coming later this year", which points past the macOS 27 release, now dated to 14 September 2026. Apple has not tied the feature to that date, and neither will we.

The limit most coverage skipped

One line in the same announcement decides whether any of this reaches you, and most write-ups left it out. Apple's availability note reads: "Generated subtitles will be available in English in the U.S. and Canada." That is a language restriction and a regional one at once. If your Mac is outside those two countries, or the audio you want captioned is not English, this is not the feature you have been waiting for. Live Captions stays the only thing built into macOS that will help. Apple has not said whether or when the list widens.

Crunchyroll and the Subtitles You Did Not Ask For

There is a second reason people search for AI subtitles, and it is not enthusiasm. It is suspicion about subtitles they are already being served.

In July 2025 Crunchyroll shipped an episode of Necronomico and the Cosmic Horror Show whose German subtitles included a line beginning "ChatGPT said". Someone had pasted a machine translation into the subtitle file and left the evidence in. The company's response, reported by Engadget on 3 July 2025, was that "AI-generated subtitles were employed by a third-party vendor, which is in violation of our agreement". It said it was working to rectify the error.

The position has since hardened. In a Radio Times interview in May 2026, Crunchyroll president Rahul Purini said the company does not use AI in its creative processes, subtitling and dubbing included. Keeping to that line, he said, is "not that difficult". Worth knowing if you assumed the industry was drifting the other way: on this particular question, at this particular company, it publicly is not.

Adding AI Subtitles to Video You Publish

Everything above is about video you are watching. If you are subtitling video you intend to publish, the market is completely different and far more crowded. VEED, Submagic, Kapwing, Clipchamp, Flixier and a dozen others will generate a subtitle track, let you style it, and export an SRT file or burn the captions into the frame.

They work, and for a finished deliverable they are usually the fastest route. There is one property worth noticing, because none of them leads with it: they all operate by uploading your video to their servers. For a marketing clip that is irrelevant. For an unreleased edit, a client's footage, a recorded medical appointment or anything covered by an agreement you signed, it is the entire question. If that matters, the on-device options are not a compromise, they are the only ones that fit.

AI Subtitles on a Mac Compared

Which One Should You Use

If you are on an Apple silicon Mac and want captions on something you are watching right now, turn on Live Captions and set it to caption your Mac's audio. It is free, it is already installed, and it handles the common case of a video with no subtitle track. When macOS 27 arrives, Generated Subtitles will cover the case Live Captions handles badly: a video file you want properly subtitled rather than narrated past. That is on the condition that you are in the US or Canada and the audio is English. Everywhere else, Live Captions is still the whole toolkit.

If you are publishing, use a dedicated tool and accept the upload, unless the footage is sensitive, in which case run Whisper locally instead. And if you came here to find out when VLC's version lands: nobody knows, VideoLAN included, and anyone giving you a date is guessing. Once captions exist, the more interesting question is usually what was said rather than whether it was transcribed. That is where running a model over the transcript earns its keep, and where the tools in our ranking of the best AI note takers take over.
