Who Uses Musely to Translate Manual Images
Localizing Product Manuals for Export Markets
We export machinery to 14 countries and every shipment needs a translated manual. Musely translates each manual page image in about 45 seconds while keeping our engineering diagrams and safety warnings pixel-perfect. Cut our manual localization cost from $8,000 per language to under $200.
Updating Multilingual Technical Documentation
When we release product updates, I need to update manuals in 6 languages. Musely handles the visual pages with diagrams—I focus on proofreading the technical terminology. Saves about 3 days per release cycle compared to working with a layout designer.
Reading Foreign Equipment Manuals On-Site
I work on imported industrial equipment where manuals are only in Korean or Japanese. I photograph the relevant pages, run them through Musely, and get readable English versions with all the wiring diagrams and part callouts still clear. Saves me from guessing or waiting for translation.
Translating Supplier Manuals for Resale
We import consumer electronics and need manuals in English for our US customers. The original Chinese manuals have complex diagrams. Musely translates all the text while keeping the illustrations, so our customers get proper documentation. Usually about 40 seconds per page.
Creating Multilingual Training Materials
Our factory workers speak 5 different languages. I translate our equipment operation manuals using Musely so every team has instructions in their language. The step-by-step diagrams stay intact, which is essential for safety training.
Translating Regulatory and Safety Manuals
Safety documentation needs to be precise and visually clear. Musely translates our safety manual images while preserving the warning symbols, color-coded hazard notices, and regulatory text blocks. About 95% accurate on first pass for safety terminology—I review the critical sections manually.

What Users Say About Musely for Manual Translation
4.8/5 from 1,847 reviews
“We manufacture conveyor systems and ship to 11 countries. Musely translates our 80-page operation manual images in about 45 seconds per page. The wiring diagrams and part callouts stay perfect. Saved us roughly $12,000 in the first quarter compared to hiring a technical translation agency.”
“I maintain foreign-made CNC machines and the manuals are all in Japanese. Musely translates the diagram pages so I can follow maintenance procedures correctly. About 95% accurate on technical terms—occasionally I fix a specific parameter name, but it's way faster than trying to piece it together manually.”
“Great for translating consumer electronics manuals we import from China. The diagrams and button callouts stay in place after translation. Occasionally the translated text runs slightly long in narrow callout boxes, but 90%+ of pages come out clean without any adjustments.”

Google Translate (via Lens) overlays translated text on top of images, which often misaligns with diagram callouts and warning boxes in technical manuals. Musely regenerates the full image with translated text natively placed, preserving all diagram structure and layout. Musely also supports 136 languages versus Google Lens's more limited image translation handling.
Musely handles assembly guides, wiring diagrams, exploded-view illustrations, and technical spec pages. The AI translates all text callouts and labels while preserving the underlying diagram artwork and visual layout. Part numbers, model codes, and other identifiers can be excluded from translation via the Additional Instructions field.
Musely accepts JPG, PNG, WebP, BMP, and TIFF formats up to 20MB per image.

Musely uses AI-native image regeneration that identifies warning boxes, caution symbols, and safety notice sections by their visual structure. The translated text is rendered within the original warning box boundaries and color coding, so safety hierarchy and visual prominence are maintained in the translated manual page.
Musely lets you specify text to leave untranslated via the Additional Instructions or Things to Avoid field. Common exclusions for manual translation include part numbers, model codes, serial number fields, and brand names. The AI applies these exclusions across the full image while translating all other instructional text normally.
