1. LOVABLE Build Web Apps Through AI Conversation Alone The Next Generation Development Platform From Natural Language to Full-Stack Applications
2. The AI-Driven Platform Chosen by 500,000+ Entrepreneurs Lovable is an AI-driven development platform that enables the construction of full-stack web applications through natural language conversation. Simply describe what you want to build, and AI autonomously executes everything from design to deployment.  Natural Language Interface Build applications using everyday language without technical expertise  Real-Time Code Generation Instant code generation and preview as you enter prompts  Full-Stack Support Production-ready apps using React, TypeScript, and Supabase  Complete Code Ownership All generated code belongs to you with full freedom to edit and export  Team Collaboration Lovable 2.0 enables multiplayer functionality for shared development
3. Production-Ready Apps Built with Modern Technology Lovable employs cutting-edge technology stacks to ensure that generated code meets production-level quality standards, enabling smooth transitions from prototype to production environment. Frontend React.js + TypeScript Type-safe, highly maintainable UI components Tailwind CSS Utility-first framework for responsive design Vite High-speed build tool and development server Backend Supabase PostgreSQL-based open-source platform Database Management Authentication and real-time capabilities REST/GraphQL API Automatically generated APIs Row Level Security Advanced security controls Deployment Lovable Cloud One-click deployment to production Custom Domain Independent domain name support Self-Hosting Run in any environment
4. Two Intelligent Modes: Agent Mode and Chat Mode  Agent Mode An advanced autonomous system where AI independently thinks, plans, and implements solutions for complex development tasks.  Usage-based pricing (most messages < 1 credit)  Chat Mode A conversational planning mode optimized for code changes, questions, and planning work with direct developer interaction.  Simple pricing: 1 message = 1 credit  Recommended Workflow Spend 60-70% of development time in Chat Mode to thoroughly investigate and plan implementations. Once the plan is clear, click "Plan to Implementation" to switch to Agent Mode for execution. This hybrid approach maximizes development efficiency by combining strategic planning with autonomous execution. Codebase exploration and contextual understanding • File reading and code modification with refactoring • Automatic debugging and error correction • Log and network activity inspection • Web-based document and asset retrieval • Application image generation and editing • Efficient debugging through direct problem investigation • Database structure and relationship planning • Exploring optimal implementation methods for new features • Gathering application improvement hints and suggestions • Evaluating impact of new features on existing systems •
5. Rapid Prototyping: Ideas to Reality in Minutes Landing Page Development Create landing pages that serve as the face of startups and new ventures, from design to coding, in a single workflow. Examples: Dream Catcher, PrintPigeon Features: Responsive design, SEO optimization, Custom domain support Time: 30 minutes to 1 hour Development that took days or weeks now completed in hours Prototype Development Build working prototypes for investor pitches and user testing, not just static mockups but fully functional applications. Benefits: Actual working applications rather than static mockups Use Cases: MVP validation, User feedback collection Flexibility: Immediate modifications based on feedback Transform business ideas into testable products quickly Success Stories  Alpine Ventures Investor-focused website  Awaken Ambiance Real-time voice AI demo  Dream Catcher Dream journal and analysis app  PrintPigeon Online postcard delivery service

9. 10 Best Practices for Successful Development Prompting Tips 1 Clear and Detailed Prompts Describe specific page names (e.g., /dashboard) and expected behaviors in detail rather than vague instructions 2 Use Natural Language Describe requirements in everyday language, such as "Investor role users can access this component" 3 Leverage Screenshots Provide visual information when explaining bugs or UX issues for more effective communication 4 Set Guardrails Explicitly indicate files that should not be edited, such as "/shared/Layout.tsx (do not edit)" 5 Incremental Implementation Break work into small, testable chunks rather than implementing five features at once Workflow Tips 6 Utilize Knowledge Files Document product vision, user journeys, and design systems, sharing them across all prompts 7 Active Use of Chat Mode For 2-3 minor bug fixes, switch to Chat Mode to investigate root causes before implementation 8 Version Management Pin (version lock) working features before implementing new ones to maintain stable versions 9 Small Modifications with Visual Edit Use the free Visual Edit feature for text, color, and font changes to preserve credits 10 Remix for Fresh Starts When stuck in a bug loop, Remix (create clean copy) the project and rebuild for faster resolution
