How to choose
Which languages does it need to support?
Check the supported-languages information against the languages you need to translate.
Compare that alongside translation modes so the software fits the kind of translation work you have in mind.
Does it support glossaries and translation memory?
Check glossary support and translation memory when comparing how a tool handles your translation workflow.
These are separate comparison points, so review both rather than assuming one means the other is included.
Does it connect to the apps I already use?
Check the native integrations listed for a tool against the apps you rely on.
If you need a connection beyond those integrations, check whether it offers API access; an API is a way for software to connect to other software.
Where can I use the software?
Check the listed platforms before choosing. The board covers API, web, Windows, macOS, Android, and iOS availability.
Confirm that the platform you need is listed for the specific tool you are considering.
Can I try it before paying?
Compare the free-plan and paid-from details, and check whether a free trial is offered. A free plan and a free trial are different options.
If you need to read or change the code, check the tool's open-source mark and licence.
