Are you looking for someone who will dedicate their time end effort to bring the best Czech version of your game or book to life? Someone who pours her heart and soul into what she does? Someone who has been reading and writing and loving books and playing games for as long as she can remember? Then feel free to get in touch. I am a native Czech translator and an avid reader and gamer.

Most AI-generated Czech is technically correct. But that's not enough. Native speakers instantly notice when something feels translated, overly literal, or simply unnatural. The words are correct — the language isn't. That's where I help. I specialize in Czech AI localization, subtitle QA, proofreading, and language review. My work is focused on one thing: making Czech sound natural, fluent, and believable to real people. Whether it's subtitles, chatbot responses, app content, websites, onboarding flows, or AI-generated text, I adapt the language so it feels like it was originally written in Czech — not generated by a machine. Over the last few years, I've worked on AI-generated subtitles, chatbot testing, localization projects, proofreading, transcription, and Czech language QA. I understand the difference between a translation that is merely correct and one that actually works for the end user. What clients typically hire me for: • AI localization and post-editing • Subtitle QA and dialogue adaptation • Czech proofreading and language review • Chatbot and AI response evaluation • App, website, and UI localization • Naturalization of AI-generated content Why clients keep coming back: • 100% Job Success Score • Top Rated freelancer • 45+ completed projects • Long-term ongoing collaborations • Fast communication and reliable delivery I don't just correct Czech. I make it sound like Czech.
