According to God of Prompt on Twitter, integrating Gamma, n8n, and GPT-5 enables agencies and businesses to fully automate their proposal generation workflow. The process starts with n8n capturing client information instantly from form submissions. GPT-5 then utilizes this data to generate comprehensive, personalized proposal briefs that include objectives and tailored recommendations. This setup streamlines client onboarding, reduces manual work, and increases proposal speed and accuracy, offering significant operational efficiency and business scalability for service-based organizations (source: @godofprompt, Twitter, Nov 27, 2025).
