CLARA – AI-Powered Language and Cognitive Assistant for Everyday Use Many people find that finding words or expressing themselves becomes more challenging over time. This can affect everyday communication and personal well-being. The idea behind the CLARA app is to offer digital support for language- and cognition-related activities in daily life. CLARA is an AI-powered language assistant that captures your personal language context and processes it using a large language model (LLM). This enables interactive chats, support with word formulation and expression, image-based descriptions, and playful language exercises. By incorporating individual language context, CLARA adapts to personal preferences and provides personalized support for everyday communication. Key Features • Interactive chats: Communicate via text or voice in a dialog-based format. CLARA uses your personal language context to better interpret prompts and respond in a natural and contextual way. • Personalized language support: CLARA considers people, interests, and topics that matter to you and gradually adapts to your individual language usage. • Playful language exercises: Explore word- and language-based games such as word associations, opposites, and missing-vowel challenges, personalized to your language context. • Simple and accessible design: Clear layout, large text, and intuitive navigation—designed for easy everyday use. • Privacy first: Your data belongs to you. CLARA does not use your inputs for model training and processes data solely to support your personal app experience. CLARA is a digital assistant for language-related activities in everyday life and is continuously being further developed.

A meditation timer that gets out of your way. No subscriptions. No guided sessions. Just press start and sit. I built Oku because every meditation app I tried wanted me to subscribe, watch a tutorial, or pick from a library of guided sessions. I just wanted to sit down, meditate and track my sessions. So that's what this app does. Set your time anywhere from 1 to 90 minutes with a simple drag gesture. Pick a completion sound you like: singing bowl, soft bell, or warm chime. Press begin. That's the whole app. No subscriptions. No account. No ads.
