Why we like it

Fluen stands out in the Adobe Exchange library for handling both captioning and multilingual subtitle translation inside Premiere Pro, with the language-aware segmentation and glossary controls that long-form work tends to lean on.

What is Fluen?

Fluen adds professional AI captioning and subtitle translation to Premiere Pro, built for editors working on long-form content such as documentaries, interviews, episodic series, courses, and corporate video. It exports your sequence audio, transcribes it in the cloud, and returns clean, accurately timed captions, with the spoken language detected automatically.

For translation, Fluen converts new or existing caption tracks into 50+ languages. It adapts segmentation and cue timing to each language, so line breaks and reading pace stay natural rather than forcing a word-for-word copy of the original. You can set characters per line, lines per caption, reading speed, and speaker labels, and add a glossary so names, brands, and technical terms come out right.

Captions and translations are generated automatically while you keep editing. Refine them with quick edits in Premiere or in the full Fluen web editor, then re-sync to bring the polished captions back onto your timeline. Finished subtitles import into your project as SRT files. Fluen requires a Fluen account and an internet connection.

Who is Fluen best for?

Fluen is best for editors working on long-form content like documentaries, interviews, episodic series, courses, and corporate video who need captions or subtitle translation without leaving Premiere Pro.

How much does Fluen cost?

Frequently asked questions

Which Premiere Pro versions does Fluen support?

Fluen works with Adobe Premiere Pro 25.6.0 and later, and the developer notes it has also been tested on Premiere Pro 26.2. It runs from a panel inside Premiere, where you sign in to your Fluen account and generate captions or translations. Because transcription and translation happen in the Fluen cloud, you also need an internet connection while processing. If you are on a release older than 25.6.0, you would need to update Premiere Pro before installing. Full details are on the developer's page.

Does Fluen need an internet connection and an account?

Fluen requires a free Fluen account, which you sign in to from the panel, plus an active internet connection. It exports your sequence audio and processes both captioning and translation in the Fluen cloud rather than on your machine. Audio and captions you process are uploaded securely to your Fluen cloud account. The developer publishes its privacy policy at fluen.ai/privacy and terms at fluen.ai/terms, so review those if cloud processing matters for your project. Without a connection and a signed-in account, Fluen cannot generate results.

Is Fluen free to use?

Fluen is listed here as free, and it is free to install with a free trial included. The trial lets you caption and translate up to 3 media with up to 3 target languages each; on the trial, translations cover the first 15 minutes of each video and SRT exports carry a small watermark. Continued use beyond the trial requires a paid Fluen plan, billed through your Fluen account at fluen.ai. For current licensing and plan details, check the developer's page.

How many languages can Fluen translate captions into?

Fluen translates new or existing caption tracks into 50+ languages. Rather than copying the original word for word, it adapts segmentation and cue timing to each language so line breaks and reading pace stay natural. You can also set characters per line, lines per caption, reading speed, and speaker labels, and add a glossary so names, brands, and technical terms are rendered consistently. Finished subtitles import into your Premiere Pro project as SRT files, and you can re-sync polished captions back onto your timeline when you are done.
