Overview
CrystalSound
CrystalSound is an AI-driven audio enhancement tool that acts as a smart layer between your microphone and your communication apps. You can eliminate distracting background noises like barking dogs, construction, or keyboard typing in real-time, ensuring your voice remains the center of attention. It works by creating a digital fence around your voice, filtering out everything else so you sound professional regardless of your environment.
Beyond simple noise suppression, you can use the platform to enhance your vocal quality and even remove echoes from empty rooms. It is designed for remote workers, call center agents, and content creators who need studio-quality audio without expensive hardware. You can integrate it instantly with popular platforms like Zoom, Microsoft Teams, and Google Meet to maintain clear communication during every session.
Mainstay
Mainstay helps you bridge the gap between your organization and the people you serve through purposeful, AI-driven conversations. Originally built to help students navigate the complexities of college, the platform now supports both higher education institutions and modern workplaces. You can use its behavioral science-backed messaging to proactively reach out to individuals, answer their questions instantly, and guide them toward important milestones like enrollment or employee onboarding.
The platform focuses on boosting retention and engagement by meeting people where they are—on their phones. By automating routine interactions with a 24/7 chatbot, you free up your staff to handle more complex, high-touch tasks.
