Lovable AI Tutorial for Beginners - Build Your First App

About this video

David, in a walkthrough partnered with Lovable, builds a voice-to-calendar web app in Lovable by describing it in plain English. He orients viewers to the workspace, templates, and prompt box, then explains prompt structure: start with a clear goal/problem and a simple user flow (ideally one to two features), add design language, start in Plan mode, and ask Lovable to ask clarifying questions before building. The example prompt creates a mobile-feeling web app where a user rambles a to-do list, confirms extracted tasks, and adds them to Google Calendar assuming 30-minute durations. After answering Lovable’s questions and approving its plan, he connects Google Calendar, tests voice capture, and iteratively fixes issues: rounding start times to the next free 15-minute increment, parsing spoken dates/times and durations (words like tomorrow, Friday afternoon, next Tuesday morning), and fixing a timezone offset — using screenshots pasted into the prompt and returning to Plan mode for technical changes, including asking for non-technical explanations. He then adds per-user Google sign-in for publishing, runs Lovable’s recommended security scan (noting fixes via ’try to fix all’ do not cost credits), publishes to a free URL (custom domain requires Pro), and converts it to a Progressive Web App installable to a phone home screen without an app store.

Key takeaways

• A good Lovable prompt states the goal, a narrative user flow, and design cues, starts in Plan mode, and invites clarifying questions before any build
• Start with the simplest version plus one to two features; more features upfront makes visual and functional tweaking much harder
• Iterate with specific prompts — e.g., rounding to 15-minute increments and defining rules for morning/afternoon/next Monday — and paste screenshots to show bugs
• Publishing safely requires switching from a hardcoded personal calendar to per-user Google authentication and running the in-depth security scan
• A published Lovable web app can be made installable as a Progressive Web App with a custom icon, giving a native-app feel without app-store submission
