KeyRay is a cross-platform productivity application designed to make typing faster and easier on Mac, Windows, and Linux. It combines automatic keyboard-layout switching, spelling and typo correction, and voice dictation with tools for working with text through neural-network integrations. As users type, KeyRay can detect the intended language and correct the keyboard layout, while personal dictionaries help improve recognition of less common words. Its voice input processes audio locally, adds punctuation, and works across system applications without requiring an internet connection; the company says typed text and recordings remain on the user’s computer.

Additional features include text translation through DeepL, custom AI prompts for selected text, automatic sentence capitalization, special-character substitutions, list continuation, hotkey customization, case changes, and correction of accidental double capitals. Users can configure exceptions for individual applications. KeyRay offers a 14-day trial, a one-time Standard license, and a Pro subscription with expanded features and device synchronization. For organizations, it provides centralized license management and options for secure deployment within a company’s own environment.
