THE BIG PICTURE
Dubly.AI is an AI video translation platform that dubs videos into other languages while aiming to keep the result natural enough that viewers cannot easily tell it was generated. The site positions the product around three pillars: high-quality lip sync, voice cloning that preserves the original speaker's voice, and a translation editor that gives users control over individual words and segments. It is marketed primarily to companies — e-learning, marketing, internal communication and enterprise teams — rather than only individual creators.
The workflow is credit-based and built around video minutes. One credit translates one minute of video into one target language, and enabling lip sync doubles the cost to two credits per minute and language. The platform accepts mp4 and mov uploads up to 5 GB and also supports importing from a YouTube link. It advertises 100+ source languages, 40+ target languages and dialects, unlimited target languages per video, and unlimited video length. Outputs include MP4 video, MP3 audio (full mix, voice only or background only) and SRT subtitle files, with optional burned-in subtitles.
A notable part of the offering is data handling and European hosting. Dubly.AI states that videos are stored on servers in Germany, that it is GDPR-compliant, that a data processing agreement is included, and that customer content is not used to train AI models. The company also emphasizes human support on every plan, an included API for automation, and unlimited users with role-based access including an external reviewer role that does not consume a seat.

WHAT YOU CAN DO
Get to know the capabilities. Find your own way to use them.
Translates video content into other languages, detecting speakers and language automatically. The platform advertises 100+ source languages, 40+ target languages and dialects, unlimited target languages per video and unlimited video length.
Adjusts a speaker's mouth movements to match the translated language so the video appears as if the speaker delivered the translated version. It is optional and enabled per video after the initial translation step, and costs two credits per minute and language instead of one.
Clones the original speaker's voice so it stays recognizable in the new language, or lets users pick a replacement voice from a library or upload their own. Multi-speaker detection supports 1, 2 or auto 3+ speakers with per-segment speaker assignment and voice preview.
A per-segment editor where source script, translated script and timing sit side by side. Users can fix individual terms, exclude words from translation, control pronunciation, and set tone, formality and writing style, with unlimited revisions and the ability to apply edits across all languages at once.
Company-specific terms can be stored in a fixed glossary, and custom translations per term hold wording consistently across all target languages. Dubly.AI also offers help building the glossary during onboarding.
Every video comes with translated subtitles timed to the new audio track. Outputs include MP4 video, MP3 audio as full mix, voice only or background only, and SRT subtitle files, with burned-in subtitles available in two styles and a custom accent color.
Unlimited users at no extra cost, with Owner, Admin, Member and external Reviewer roles. Reviewers can sign off on a dub without using a seat, share links can be PIN-protected, and projects, folders and multiple workspaces are supported.
API access is included at no extra cost and lets teams wire translation into existing workflows instead of uploading videos one by one through the interface. The site shows a POST /v1/translations endpoint accepting a video URL, target languages, lip sync and voice cloning flags.
MADE FOR YOUR WORKFLOW
Course and training producers can translate instructional videos into multiple languages while keeping the instructor's voice and lip movements consistent, which the site presents as a core use case for e-learning and training content.
Marketing teams and creators can adapt promotional or social clips for different markets, using tone and formality controls and the translation editor to adjust wording before publishing.
Organizations can localize internal videos for multilingual workforces, with role-based access and reviewer sign-off so local teams can check translations before distribution.
Large organizations can process whole video catalogues in batches, either through the included API or by sending a Google Drive or Dropbox link so Dubly.AI processes the batch on their behalf.
YOUR FIRST STEPS
Upload a video file (mp4 or mov, up to 5 GB) or import from a YouTube link. Dubly.AI detects speakers and language automatically, and the first translation is ready in minutes according to the site.
Select from 40+ target languages and dialects. The AI translates and clones the original voice; lip sync is optional and enabled per video after this standard translation step.
Read through the translation and change anything that does not fit. Select a word, pick an alternative, and repeat as often as needed at no extra cost. Edits can be applied across all languages.
Switch on lip sync so mouth movements match the new language, then download the finished video in full resolution. Lip sync is optional and enabled per video after the standard translation step.
PLAN YOUR NEXT STEP

One credit translates one minute of video into one target language. A 10-minute video in three languages therefore costs 30 credits. Lip sync doubles the cost to two credits per minute and language. Partial minutes are rounded up to the next full minute.
It depends on how they were bought. One-time purchase credits never expire and stay in the account until used. Monthly plan credits are valid for that month and expire at the end of it. Yearly plan credits stay valid for the full 12 months of the term.
No. Dubly.AI states that none of the uploaded data, whether video or audio, is used to train AI models. Customer data is handled in isolation within a secure sandbox environment and is never mixed with other customer data.
According to the site, users retain full rights to all translated videos. Dubly.AI states it does not claim any rights to the final content and places no restrictions on how the videos are used.
