Lexibird (formerly Translatium for Mac & PC) vs Langfinity (formerly Byrdhouse)

Lexibird is the translation platform from WebCatalog that replaced Translatium. It targets businesses and professionals who need secure, accurate translation across text, images, audio, and documents in more than 200 languages.

The product runs as native desktop apps on macOS and Windows, with browser extensions for Chrome, Firefox, Edge, Opera, Brave, and Vivaldi, plus a PopClip extension for translating selected text in other apps. Beyond straight translation, Lexibird bundles a dictionary with definitions and synonyms, OCR for images and screenshots, real-time voice dictation, text-to-speech, and audio transcription.

Lexibird fits teams and individuals who translate constantly during their workday: support staff handling multilingual tickets, writers working across languages, and anyone who needs quick lookups without opening a separate browser tab. Credit-based plans scale from a free tier to Pro and Business subscriptions with higher monthly limits.

Langfinity delivers real-time voice and text translation for multilingual meetings, webinars, and live events. Pick your language once and follow the conversation as others speak in different languages, with translations shown on screen and read aloud through voice avatars.

The platform trains on company-specific terminology so industry jargon in manufacturing, technology, transportation, and other sectors translates with context instead of generic word swaps. Baseline models for popular language pairs reach over 85% accuracy, with faster voice-to-text under 300 milliseconds and voice-to-voice output in one to three seconds.

Langfinity works inside Microsoft Teams and Zoom, and supports in-person events through QR codes that let attendees get live translation on their phones. Organizations use it for global team meetings, church services, conferences, and client calls where hiring human interpreters would be slow and costly.
