The 4 Best HBO Max Dual Subtitle Extensions in 2026

The best extension for HBO Max dual subtitles is Sublo if you want the original line and a translation in any of 58 languages, InterSub if you want to look up words as you watch, Trancy if you watch a lot of YouTube too, and Immersive Translate if you also translate web pages and PDFs. Of the subtitle extensions we compared, these four name HBO Max.

Why you might need one at all: HBO Max's own subtitle menu depends on where you live. A popular series has around 26 subtitle languages in Germany or the UK, but often only the local language and English in Spain, France or Poland. None of the popular series in our data has Arabic, Hindi or Korean subtitles, in any country covered. The numbers are further down.

Sublo is our product. We list it first because it names more streaming services than any other tool here and translates into 58 languages, and we say plainly where the others do something better. Platforms are as each vendor names them on its own website or store listing, checked in November 2026.

The 4 extensions at a glance

Services as each vendor names them on its website or store listing, checked November 2026. These lists change, so check the vendor's page before you pay.

1. Sublo: best for translating HBO Max subtitles

Best for: viewers and learners whose language HBO Max doesn't offer, or who want two lines at once
Works on: HBO Max, Netflix, Prime Video, Disney+, Hulu, Paramount+, Peacock, Crunchyroll, YouTube, Apple TV+, MUBI and Plex; other video sites can be switched on from the popup

Sublo takes the subtitle track HBO Max is playing and shows a translated line together with the original, or only the translation, in real time. The translation comes from Google Gemini, an AI model that translates whole lines in context, into any of 58 languages. That is the way around a short subtitle menu: if a series has English subtitles in your country, Sublo can translate them into Arabic, Korean or Hindi as you watch.

Install it in Chrome or Edge, pick the two languages in the popup and press play. Size, position and colours of both lines are adjustable. The free plan includes a daily allowance of translated subtitles on every supported service, without an account or card. Pro removes the limit from €2.89 a month billed yearly.

2. InterSub: best for looking up words while you watch

Best for: learners who want to build vocabulary from HBO Max series
Works on: HBO Max, Netflix, YouTube, Prime Video, Crunchyroll, Udemy and Coursera, according to its website

InterSub pairs dual subtitles with a pop-up dictionary, so you can check a word without switching to another tab. Its website names HBO Max along with Netflix, YouTube, Prime Video and Crunchyroll, and course sites such as Udemy and Coursera.

Dual subtitles are free, with a limited number of word lookups. AI subtitle translation is in its paid plans. If vocabulary is your goal, it is the better choice here. If you mainly want to follow the plot in your own language, Sublo is the more direct route.

3. Trancy: best if you also watch a lot of YouTube

Best for: learners who split their time between YouTube, HBO Max and online courses
Works on: YouTube, Netflix and HBO Max, plus TED, edX and Coursera, according to its website

Trancy adds bilingual subtitles and is at its strongest on YouTube. Its website also names Netflix and HBO Max, and course platforms such as TED, edX and Coursera. That suits you if you mix series with online courses.

You need an account to use it. The free plan translates with Google Translate; the paid plan adds AI models such as GPT, Claude and Gemini. If you'd rather install an extension and start an episode without signing up, that is the main practical difference to Sublo.

4. Immersive Translate: best if you translate more than video

Best for: people who also translate web pages and PDFs
Works on: YouTube, Netflix, Prime Video, HBO Max and many other video sites, according to its website

Immersive Translate is a general translator for web pages, PDFs and many video sites, with bilingual video subtitles. Its video page names HBO Max, together with YouTube, Netflix and Prime Video.

You choose the translation service yourself, among many such as ChatGPT, DeepL, Google Translate, DeepSeek and Gemini. A Pro plan exists; check its website for what each plan includes. It suits you if you want one extension for reading and watching. If HBO Max subtitles are the main job, see how the two compare in Sublo vs. Immersive Translate.

Which subtitles HBO Max offers in your country

HBO Max lets you pick one subtitle language at a time, from the ones a series offers. Which ones those are depends more on your country than on the series. Our overview of HBO Max subtitle languages by country counts the subtitle languages of the most popular series in each country. This is what it found:

• Around 26 languages are typical in Germany, the UK, Ireland and Italy.
• Two languages, the local one and English, are typical in Poland, Spain, France, Turkey, the Netherlands, Portugal, Romania, Hungary and Bulgaria.
• Three at most in most of Latin America; four at most in Brazil.
• Five at most in South-East Asia and Hong Kong.
• No Arabic, Hindi, Bengali, Urdu or Korean subtitles in any country covered.

The same series can look very different from one country to the next. House of the Dragon has subtitles in 29 languages in Germany and the UK, 23 in Poland and Spain, 5 in Singapore and 3 in Brazil.

So open the subtitle menu of the series before you install anything. If your language is there and one line is enough, HBO Max's own settings will do. If it isn't, or you want the original and a translation on screen together, you need an extension that translates the subtitles HBO Max does have. Look up your language: Arabic, Korean, Hindi or all languages. Data: Streaming Availability API by Movie of the Night, November 2026.

Popular extensions that don't name HBO Max

Three well-known subtitle extensions are not ranked here, because HBO Max is not among the services they name:

• Language Reactor: built for Netflix and YouTube, with a strong study workflow and translation by Google Translate. It made dual subtitles popular, and for studying on those two services it is the strongest choice.
• Dualsub by Dualsub Studio: YouTube first; its store listing also names Netflix, Disney+ and Coursera. Several unrelated extensions use a similar name, so check the publisher.
• eJOY: an English-learning toolkit for Netflix and YouTube, with word saving and flashcards.

If you use one of them on Netflix or YouTube, keep it there and add one of the four above for HBO Max. For Language Reactor in particular, see our Language Reactor alternatives for HBO Max.

Which one should you pick?

• Your language isn't in HBO Max's menu, or you want the original and a translation together: Sublo.
• You want to look words up as you watch: InterSub.
• You watch a lot of YouTube and online courses too, and don't mind creating an account: Trancy.
• You also translate web pages and PDFs, or want to choose the translation service: Immersive Translate.
• HBO Max already offers your language and one line is enough: no extension; use HBO Max's own subtitle settings.
• You also study with Netflix and YouTube: Language Reactor there, and one of the four above on HBO Max.

How we compared them

We started from the extensions in our full list of subtitle extensions. We set aside two study tools: asbplayer, which is not a translator, and Migaku, which is built around Anki-style flashcards. Of the other seven, we ranked the four whose own website or store listing names HBO Max. We compared them on which streaming services each one names, whether it shows two subtitle lines, how the translation is made, and what it adds on top, such as a dictionary. The platform lists come from each vendor's website or store listing in November 2026.

We don't list prices for the other tools, because they change often; check them on the vendor's site. LingQ is a full course platform rather than a subtitle extension, so it is left out. Sublo is made by an independent developer in Hannover, Germany, and is not affiliated with HBO Max or any other streaming service.

Frequently asked questions

How do I get dual subtitles on HBO Max?

HBO Max shows one subtitle language at a time, so dual subtitles (some people say double subtitles) need a browser extension. With Sublo, install it in Chrome or Edge, pick the two languages in the popup and press play: the original and the translated line appear together. Details in our guide to dual subtitles on HBO Max.

Does HBO Max have Arabic or Korean subtitles?

Not in our data: none of the popular series we looked at has Arabic, Korean, Hindi, Bengali or Urdu subtitles, in any country covered. Sublo can translate the subtitles a series does have, for example English, into Arabic or Korean while you watch. See Arabic and Korean subtitles on HBO Max.

Does Language Reactor work on HBO Max?

HBO Max is not among the services Language Reactor names: it is built for Netflix and YouTube. For dual subtitles on HBO Max, use an extension that names it, such as Sublo, InterSub, Trancy or Immersive Translate. More in Language Reactor alternatives for HBO Max.
