At my job I have to translate a lot of text from one language to an other one. It's a software and procedure manual. This tool I would like to use it also in future. I prefer open source.
I'm looking for a tool, where I have one text left (source language), the other right (target language), and a glossary with the given fixed translations. E. g. Names used in the software.
translate.google.com is nice, has no glossary. deepl.com is fine, the glossary is to expensive for me.
added: I want open source, because I want to use it later also for my theses papers next year. The work I spend in my glossary should be usable in future.
