Where can I translate technical text in Berlin for free

I’m currently helping a small startup in Berlin with some technical documentation, and translating everything from German to English is taking forever. Standard translators often miss the nuances of engineering terms. I needed a tool that was more sophisticated but didn't require a monthly subscription. I’ve been testing out Overchat AI's platform because it gives access to advanced models that handle technical context much better. It’s completely free to use online, and I didn’t even have to sign up. It has definitely speeded up my workflow this week. How do you guys handle translations for work? I’m always worried about losing the original meaning in complex sentences, but these newer models seem to be getting much better at it.
