Internal systems block copying
Plenty of ERPs, vendor consoles and remote clients render text you simply cannot select.
For engineering and operations teams
The doc that fixes your bug is in Japanese.
Documentation, ERP panels, vendor consoles, an error message inside a screenshot. Translate it in place and understand what the system is actually asking for.

Illustrative animation: the app selects part of the screen — a map, an article, a post, an error log or a game — and shows the translation in the same place as the original.

Direct answer
How do you translate technical documentation without breaking your flow?
To translate technical documentation — English docs, error messages, tool interfaces — select the region on screen with Sincron Screen Tools and read the translation without switching windows. The Windows app preserves the commands, paths, and field names around the translated text, and summary mode explains what an error message is asking for, not just what it says.
The problem
Where teams get stuck
Errors outside English
A message in Japanese, Chinese or German kills your search: you do not even have the term to look up.
Context is lost in the ticket
The screenshot goes in with no annotation, a colleague opens it and cannot tell which of the twelve lines matters.
How it works
From an unreadable error to a clear ticket
Select the message and its surroundings
Capture the error together with the screen it appeared on. A code alone says less than a code in context.
Read it translated without breaking the log
Identifiers, file paths and error codes stay readable; what changes language is the part written for humans.
Ask what is actually happening
The summary explains what the message indicates and which part looks like the cause — and says when it is unsure.
Annotate and attach it to the ticket
Arrow on the critical line, box on the wrong field, clean PNG. The ticket explains itself.
Features
Built for work screens
Code stays code
Variable names, paths and commands are not translated along with the prose.
Works over remote access
Remote session, virtual machine, legacy client: if the screen renders it, the selection reads it.
Annotation for handoff
Pen, arrow and text over the live screen, without freezing the system that is running.
No screen sent to a third party
Internal screens usually carry sensitive data. They never pass through our servers — only the selection goes, with your key, to the provider you chose.
Comparison
Working with docs in another language: before and after
| What matters | Traditional flow | With Sincron |
|---|---|---|
| Docs in another language | Translate the whole page and lose the layout | Translation over the exact passage you are reading |
| Error messages | Manually searching the error text | The summary explains the cause and the suggested fix |
| Commands and paths | Risk of translating what should stay as-is | Code and paths preserved around the translation |
| External tool interfaces | No translation possible at all | Any rendered text on screen becomes readable |
| Switching between windows | Dozens of switches per hour | One shortcut, without leaving the editor |
Questions from people running systems
Does it translate an error inside a system that blocks copying?
Yes. Reading happens from the screen, so ERPs, vendor consoles and remote clients work even without selectable text.
Will translation mangle code snippets?
The goal is to translate the prose and leave identifiers, paths and commands untouched.
Does it work in a remote session or a VM?
It does: the capture comes from your local screen, so anything displayed in your window can be read.
Can I use it in an environment with sensitive data?
You pick the provider: OpenAI or OpenRouter. The selection goes with your key straight to it, never through us, and no capture is saved unless you save it. Annotating and capturing send nothing at all.
Does Sincron translate the whole documentation at once?
It translates the region you select — a paragraph, a parameter table, or a full visible page. The original layout stays on screen as your reference.
Are commands and code snippets preserved?
Yes. The translation focuses on prose and keeps commands, flags, paths, and field names intact, so you can copy the example without errors.
Does it work inside terminals and IDEs?
It works over any visible window on Windows: editor, terminal, browser, Git client, or remote tooling.
Is it useful for learning in another language?
Yes. Summary mode explains the concept of the selected passage in plain language — helpful when you are learning the language and the technology at the same time.

Best tools to translate technical documentation
The risk here is not failing to understand. It is the tool translating what it should not — variable names, error codes, commands.
Sincron Screen Tools vs DeepL
Not the same category of tool. One translates text you have; the other reaches text you cannot grab.
Sincron vs PowerToys Text Extractor
PowerToys is free, it ships from Microsoft and it runs on your machine. If it solves your case, that ends the conversation.
Translate Chinese straight off the screen
Scientific papers, industrial manuals, system panels, online stores. Chinese usually recognizes well — the errors come from two specific places.
Translate Russian straight off the screen
Unlocalized games, industrial software, technical documentation, forums. Cyrillic is easy to recognize — the font is usually the problem.
Other use cases
Scientific papers and figures
Charts, tables and captions the PDF will not let you copy.
Posts, tweets and screenshots
Text trapped inside an image, a thread in another language, a regional meme.
Games, manga and subtitles
Menus, dialogue and speech bubbles that never got a version in your language.
