Zosha is the anti-course for practical AI skills. Learn by doing one short workplace round. Keep one useful move. Then use it on the work already in front of you. No coding required. THE WHOLE PATH IS FREE Every lesson and every round is free from start to finish. There is no round limit and nothing in the learning path sits behind a wall. ONE REAL TASK TODAY Today gives you one clear action. Each round takes about five minutes and uses familiar moves: choose, spot, pair or build. Wrong answers give you a clue and another try. When you finish a round, Zosha saves the move. Tap Use this on real work and paste an email, document, decision or task. You do not need a perfect prompt. A PLAYBOOK FOR YOUR WORK Every finished round saves one prompt, pattern, check or workflow to My Playbook. Each move connects to your work field. Copy it when you need it. Mark it when you use it. Ask Zosha to help you adapt it to a real task. ASK ZOSHA IN CONTEXT Open Zosha from Today, a round or a Playbook move. Zosha uses your learning progress and work field to help with the task in front of you. Chat is unlimited. Pro members can also attach a screenshot, PDF or text file. Zosha gives the useful output first. Then it explains what Claude read and which visible details supported the result. Raw files are not stored in Zosha's database.
