Claritykey

Claritykey is a desktop application designed for individuals with dyslexia, reading difficulties, or any condition that makes digital writing challenging. Operating as a lightweight Windows utility that resides in the system tray, it provides instant text correction across any application—browsers, word processors, messaging platforms—through keyboard shortcuts, eliminating the need to copy and paste between windows. The artificial intelligence engine understands phonetic errors and contextual nuances, delivering corrections that maintain the user's original intent while ensuring grammatical accuracy and fluid communication.

Single-key instant correction. Enables the user to select any text block on screen and press a designated shortcut key (Pause/Break) to activate artificial intelligence for correcting spelling, grammar, and sentence structure. The corrected text is automatically replaced in the original location, removing the manual steps of copying between different applications and preserving focus on the task at hand.
Phonetic and contextual error comprehension. Unlike conventional spellcheckers that fail to recognize words written as they sound, Claritykey interprets phonetically spelled text common in dyslexia. The AI resolves contextual ambiguities such as homophones and sentence-level meaning mismatches, ensuring the final text conveys the intended message even when individual words are spelled correctly but used incorrectly.
High-fidelity text-to-speech conversion. Integrates a voice reading system powered by OpenRouter and OpenAI models, allowing the user to hear selected text or entire documents read aloud. This auditory feedback assists in error detection that visual scanning might miss and supports comprehension of lengthy texts without visual fatigue.
System-wide operation across Windows applications. The application functions universally across the Windows operating system, operating on any active window where text can be selected or typed. Compatibility includes Microsoft Office applications, Slack, web-based email clients like Gmail, Microsoft Teams, and development environments, providing a consistent correction experience regardless of the software in use.
Secure proxy architecture with Supabase Edge Functions. Claritykey employs a gateway of edge functions hosted on Supabase that acts as an intermediary between the local application and artificial intelligence service providers. This architectural design protects sensitive API credentials from exposure on the user's machine while centralizing authentication, rate limiting, and usage tracking.
JSON Web Token (JWT) based authentication system. Account management and subscription plans operate through JWT tokens validated by Supabase, ensuring each request to artificial intelligence services is properly authorized. This mechanism maintains security standards without storing sensitive authentication data on the client device.
Tiered subscription model with free and unlimited options. The program provides a free tier with a daily allocation of correction credits suitable for casual usage. An unlimited subscription tier removes credit restrictions, adds high-quality text-to-speech capabilities, and unlocks advanced grammatical refinement features for users requiring intensive daily usage.
Correction without disrupting the user clipboard. While the application can replace text directly in the original input field, it also offers operational modes where corrected text is placed into the clipboard without overwriting existing content. This flexibility accommodates workflows where users prefer to review changes before committing them to the original document.
Voice dictation integration and processing. Claritykey can process text originating from speech-to-text dictation systems, correcting inaccuracies that automatic speech recognition engines commonly introduce. This allows users to combine voice input with automated refinement without switching between applications or interrupting the writing flow.
Remote architecture for continuous AI model improvements. The correction logic and linguistic models reside on servers rather than within the installed application. This separation enables the development team to enhance artificial intelligence algorithms and grammatical accuracy without requiring frequent software updates on the user's machine, maintaining application stability and minimal resource consumption.
Daily credit management and usage monitoring. For the free subscription tier, the system tracks daily credit consumption through the secure proxy gateway, providing notifications when users approach their limit. Transition to the unlimited tier occurs without workflow interruption, allowing seamless continuation of correction services.
Multi-language support with automatic detection. The artificial intelligence engine detects the primary language of selected text and applies grammar and spelling corrections specific to that language. This functionality serves users working in multilingual environments or those who regularly switch between languages during their daily activities.

The development history of Claritykey began in 2023, originating from the identified gap in conventional spellcheckers when addressing phonetic spelling errors characteristic of dyslexia. The development team consists of software engineers with backgrounds in accessibility technologies, artificial intelligence implementation, and secure systems architecture. The application was designed with a primary focus on native Windows integration and API credential protection through a proxy-based architecture utilizing Supabase as the backend infrastructure. The program is written primarily in TypeScript for backend logic and edge function implementation, while the Windows desktop client is developed in C# .NET to leverage direct operating system APIs for text interception and keyboard shortcut handling.
