"Which translator is best?" is the wrong question - it depends on whether you're
translating a contract, a street sign, or wiring translation into your own app.
Here's how I split it.
Whole documents (keep the formatting)
For PDFs and Office files you want layout preserved, not just raw text. A
dedicated document translation tool
beats copy-pasting into a chat box.
On the go: text and photos
For menus, signs and screenshots, photo translation
is faster than typing. Accuracy on short, context-poor strings is the real test.
Building it into a product
If you need translation inside your own software, what matters is latency and
price at volume - read the translation API cost notes
before you architect around one.
Everyday text and study
For quick lookups and vocabulary, a good translation/dictionary tool
covers most needs. If you compare options, this
tool comparison is a fair overview.
Rule of thumb
Match the tool to the unit of work: document, photo, API, or single word. Most
frustration comes from using a phrase translator for a job that needed a
document or API tool.
