I will build an n8n AI proposal generator with RAG and human approval

Creating proposals can take a lot of time, especially when you need to collect information from different sources, work out pricing, review the details, and prepare the final document. I help businesses simplify this process by building AI proposal automation workflows using n8n, OpenAI, and other business tools. The goal is to reduce repetitive work, make proposal preparation easier, and keep your team in control of the final result. Who is this for? This service is suitable for agencies, consultants, and service businesses that regularly create customized proposals for their clients. What can I help you automate? Depending on your needs and the package you choose, I can build a workflow that: 1. Collects proposal details from forms, databases, or other approved sources. 2. Uses OpenAI to prepare a proposal draft based on the information provided. 3. Retrieves relevant business information from your documents using RAG and Supabase. 4. Allows your team to review and approve proposals through Airtable. 5. Organizes pricing details and calculates proposal totals using approved rules. 6. Creates Google Docs and PDF proposals. 7. Updates proposal records and tracks their status. A similar project I have built: I recently completed a working AI proposal automation project using n8n, OpenAI, Supabase, Airtable, Google Docs, and Google Drive. It starts by gathering the necessary information and retrieving relevant details from a knowledge base. The AI then prepares a proposal draft for human review. Once approved, the workflow calculates the totals, creates the final Google Doc, exports it as a PDF, saves it to Google Drive, and updates the proposal status in Airtable. I have built and tested this workflow myself, so I can show you how it works. How we will work together We will start by discussing how you currently prepare proposals, what tools you are using, and which parts of the process take the most time. From there, I will build the agreed workflow, test it, and provide guidance so your team can use and maintain it. The Essential package covers basic AI proposal drafting. Standard includes RAG, human approval, and PDF generation. Premium adds more customization, advanced workflow logic, and support. If your requirements don't fit one of these packages, we can discuss a custom solution. My focus is on building something useful for your business, not adding unnecessary complexity.
