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.

Hi, I'm Olena. I’ll be honest right from the start... ✅ I’m one of those translators who still believes that a good book, a marketing campaign, or a brand story needs a human soul. You won't find any machine-generated shortcuts here. Every single sentence I deliver is something I’ve personally thought through, typed, and carefully reviewed. My specialty is translating from English into Ukrainian, Czech, and Slovak. I bring years of professional experience to the table. For a long time, I worked directly within the publishing industry, handling complex translations and linguistic adaptations for a book publishing house. After years of corporate experience and seeing hundreds of titles through to print, I’ve decided to transition into full-time freelancing. This allows me to choose projects I’m truly passionate about and offer my clients a more personal, dedicated approach. Based in Prague, I operate fluently across the Czech, Slovak, and Ukrainian linguistic landscapes every day. I catch the subtle cultural details and idioms that AI and standard translators simply miss. WHAT I CAN HELP YOU WITH: ✅ Complete Books & eBooks: My true passion is long-form literature. Having worked for a publishing house, I understand the entire process of bringing a manuscript to life. I specialize in translating from English while ensuring that the author's unique "voice" remains consistent and emotionally resonant. ✅ Collaboration with Publishers & Authors: I am always open to long-term projects with international publishers or independent authors looking to bring English titles to the Czech, Slovak, or Ukrainian markets. ✅ Advertising & Marketing Copy: I don't just translate English words; I translate the "hook." I craft creative slogans and promotional texts that actually sound natural and persuasive to a local ear. ✅ Websites & App Localization: I help English-speaking businesses settle into our region by making their online presence feel native. No "dictionary-speak," just smooth, professional language. ✅ Long-term Partnerships: I am looking for clients who value quality over speed. I am fully available for extensive projects that require dedication, deep research, and attention to detail. ✅ My "No-AI" Process & Quality Guarantee: To be 100% sure about the quality, I don't work in a vacuum. Every project I finish undergoes a multi-step review. I collaborate with a network of native speakers for each specific target language to look at the final result with fresh eyes. This "double-native check" ensures that your English content doesn’t just "look right," but "feels right" to the local audience. I only use technology for the final, boring grammar and spell-check at the very end. The creative work is 100% human brainpower. If you have an English manuscript that needs care, or a brand expanding into our region, let’s get to work! I’m ready to give your project the professional attention it deserves.
