Cello sends one bite-sized AI prompt to your phone every morning — practical, copy-paste-ready, and immediately useful. Instead of staring at a blank chat box, you get a concrete starting point that shows you what these tools can really do. Beyond the daily prompt, Cello offers curated 'journeys' tailored to specific life situations: job seekers, founders, parents, and more. Each journey builds your instincts for prompting over time rather than overwhelming you upfront. Built by a former CIA and Google communications leader, the app is designed around real-world use cases, not tech demos. Available on iOS, with Android in development.
