In-app tutorials are interactive walkthroughs of what users need to know when they first use a product. They help users reach an "aha!" moment, uncover their job-to-be-done, and often encourage self-serve onboarding. There are three common types of in-app walkthroughs: customer success-led walkthroughs, automated product tours, and tooltips. Out-of-app tutorials include email messages, webinars, and video tutorials. To choose the right type of tutorial for a product, consider resources, onboarding goals, and user preferences. Key elements to pay attention to in designing in-app tutorials are modal backdrops, clear CTAs, staying on-brand with design, managing user expectations, and allowing users to opt-out. To keep users engaged throughout their onboarding journey, highlight a user's job-to-be-done, build knowledge with tooltips, shift strategies based on NPS scores, speak to customers for feedback, and continuously optimize the onboarding process.
