Cello

Cello is an AI learning tool that delivers one bite-sized, practical AI prompt to your phone every morning, plus longer guided journeys, to help everyday users get more out of ChatGPT, Claude, and Gemini. Instead of leaving people to figure out prompting on their own, Cello sends a single ready-to-use prompt each day along with step-by-step walkthroughs that show how to apply it to a real task. It is built for people who know AI chatbots exist but want concrete, low-effort ways to use them, including job seekers, working professionals, founders, and parents. The content spans practical scenarios: rehearsing for interviews, evaluating a job offer, automating workflows, organizing meeting notes into searchable or listenable formats, building simple no-code games to teach children, planning meals from a photo of your fridge, and restoring or colorizing old photos. Daily delivery keeps the habit small and repeatable, while the deeper journeys let motivated users go beyond a single prompt into a topic. Cello is available as an iOS and Android app, and no paid tiers were listed on the page reviewed, indicating a free offering at the time of review; confirm current pricing in the app stores.
