The AI then writes a complete, tailored proposal from scratch, including persuasive executive summaries, detailed scope breakdowns, and professional pricing tables.

AI Section-Level Editing & Refinement
Maintain full creative control with intelligent editing tools. For any section of your AI-generated proposal—like the executive summary or scope of work—you can issue natural language commands such as "Make more persuasive," "Make shorter," or "Rewrite in a formal tone." This allows for rapid refinement and customization without starting from scratch, ensuring the final document perfectly matches your voice and the project's requirements.
