TransMonkey
AI translator for documents, images and video
About TransMonkey
TransMonkey is an AI translation suite that handles the full range of formats people actually need translated - documents, images, video, plain text, and audio for transcription and subtitles - across more than 130 languages, in a few clicks. Its central promise is that translation should keep the thing being translated intact: a document comes back with its original layout preserved, an image has the original text automatically removed and the translation placed in its spot over the same background, and a video is transcribed, subtitled and dubbed with the background music left untouched. That matters because the painful part of translation is rarely the words themselves but the reformatting afterward - realigning a PDF, redrawing a slide, re-timing subtitles - and TransMonkey is built to remove that step.
What makes it distinct is breadth plus LLM-backed accuracy in one place. Rather than a single-purpose translator, it unifies a document translator (30-plus formats including PDF, Word, Excel, PowerPoint, up to 1500K characters), an image translator (bulk, high-resolution, up to 10MB), a video translator (transcription, subtitle translation and voiceover dubbing in 130-plus languages), and a text translator (up to 7000 characters). It is powered by large language models - ChatGPT, Gemini and Claude - alongside OpenAI's Whisper and TTS for speech, which it uses to deliver context-aware translation rather than word-for-word substitution, and it meets users where they work through Chrome and Google Workspace extensions and a YouTube video translator add-on.
You pick the tool for your format and upload the file. For documents, TransMonkey ingests PDF, Word, Excel, PowerPoint and more, translates with an LLM and returns the file with the original formatting retained, handling large files smoothly. For images, it detects and removes the original text, translates it and composites the result back over the same background, with bulk processing and instant download. For video, it transcribes the audio, translates and generates subtitles, and can dub a translated voiceover while preserving the background music - with a YouTube extension for in-place viewing. For text, you paste up to 7000 characters and get fast, context-aware output across 130-plus languages. Because the engine is LLM-based and also uses Whisper for speech-to-text and TTS for voice, the output aims for contextual accuracy rather than literal rendering, and the browser and Workspace extensions let you translate inside the apps you already use without copying and pasting.

TransMonkey fits anyone who regularly moves content across languages and cannot afford to lose formatting in the process. It suits professionals and small businesses translating contracts, reports and presentations who need the layout preserved; designers and marketers localizing images and graphics in bulk; content creators and educators subtitling or dubbing video for international audiences; and teams that live inside Google Workspace or Chrome and want translation available in place. The pay-as-you-go credit packs suit occasional, project-based needs, while the Pro monthly and discounted yearly subscriptions fit people translating large volumes of documents, images and video every month. It is a weaker fit for organizations that require certified human legal or medical translation with sign-off, since TransMonkey is an automated LLM translator optimized for speed, breadth and format fidelity rather than attested professional certification.
