Sleep Cycle, a leading sleep technology company, today announced the launch of Luma, a proprietary AI-powered sleep coach designed to revolutionize how users understand and improve their sleep.
Built on Sleep Cycle’s proprietary machine learning and audio analysis technology, Luma now takes the app’s data visualization one step further by providing context, clear explanations, and step-by-step recommendations that evolve with each user’s habits and needs. Luma is available to new iOS users beginning December 3, with a broader rollout to existing users in early 2026.
A New Era of Sleep Coaching
With more than a decade of expertise in sleep science, behavioral data, and as the world’s largest collection of real-world sleep data, Sleep Cycle recognizes that many users know how they sleep, but not how they can improve their sleep. Luma bridges that gap.
Key features of Luma include:
- Conversational coaching: Personalized, chat-based guidance that adapts to each user’s habits and progress.
- Comprehensive data analysis: Access to weeks, months, and years of sleep insights including stages, snoring, and patterns like social jetlag.
- Personalized follow-ups: Luma remembers context such as partner presence, pets, or stress triggers for more natural, human-like dialogue.
- Science-driven insights: Statistical modeling filters day-to-day noise and identifies habits most correlated with better sleep quality.
- Privacy-first design: Luma is built with Sleep Cycle’s strict data protection framework, treating all sleep-related information as health data, applying the highest level of security.
“At Sleep Cycle, our mission has always been to democratize access to good sleep. We believe quality rest should be attainable for everyone, not just those with access to sleep labs. With Luma, we’re stepping into the wider AI coaching space and giving users a tool that helps them make sense of their own data, connecting daily habits to how they feel, perform, and recover. This is the first step toward a broader AI coaching vision, helping people use data not only to rest better, but to live better,” said Erik Jivmark, CEO of Sleep Cycle.
AI’s Expanding Role in Sleep Technology
AI tools like Luma represent a new phase in personal health: one that uses data not just for awareness, but for behavioral improvement.
With Luma, Sleep Cycle is expanding its offering to provide AI-powered personal coaching, connecting the science of sleep with the broader goals of health, focus, and recovery. Sleep Cycle has built an adaptive system that learns from over three billion nights of real sleep data while maintaining strict privacy and security standards.
As consumers raise questions about how AI coaching tools use personal data, Sleep Cycle has taken a different approach. Luma can start a conversation at any time, but it only accesses a user’s sleep data when two conditions are met: The user has chosen to store their sleep data securely on Sleep Cycle’s servers, and the user initiates a chat that requires Luma to reference that data. Even then, Luma only uses the specific, relevant, and anonymized portions of a user’s sleep history to generate its insights.
Sleep Cycle never shares sound data. Users may choose to share personal information in free-text conversation and the responsibility for such disclosures lies with the user. This also applies to personal sleep notes, where Sleep Cycle does not impose any limitations on the content a user may enter.
Additionally, Sleep Cycle protects its users via encryption, secure cloud storage, and tightly limited internal access. Users remain in full control with sleep data being stored locally on a user’s device and is only backed up or processed with explicit consent, in accordance with GDPR requirements.
Using statistical modeling, natural language processing, and real-time analysis, Luma delivers guidance that feels personal, relevant, and grounded in science, not guesswork.
In summary, Luma marks an expansion in Sleep Cycle’s offerings, now continuing and enhancing its mission to improve sleep and, in turn, improve global health by uniting trusted sleep data with personalized AI guidance, and ensuring users remain fully in control of what they share, Luma advances the company’s mission to make good sleep and improved health accessible to everyone.
