I need a lightweight, browser-based tool that takes three inputs—Vendor profile, Opportunity details, and Scope of work—and turns them into a well-structured business proposal with a single click. My first thought is to call OpenAI GPT-3 for the heavy lifting, but I’m happy to lean on any genuinely free language model or API you recommend as long as the quality stays high and the running costs stay negligible. Core flow • Clean web form where I enter the three data blocks above. • The app sends this data to the chosen AI engine and receives a draft. • A rich-text editor opens the draft so I can tweak, reorder, or add sections on the spot. • A simple template selector (fonts, colours, headers, logo placement) lets me re-skin the document before export. • One-click export to PDF and Word. Nice to have Autosave of past proposals, basic user authentication, and an admin area to add or modify templates—but these can be phased in if time is tight. Timeline & scope I expect the whole job to fit comfortably into about 15 calendar days of part-time effort (roughly 3–4 hours a day). I’m flexible on the stack; a React/Node or Django/Python combo would suit me fine, but choose what lets you integrate GPT-3 or its free equivalent quickly and keeps hosting simple. Deliverables 1. Source code in a public or private Git repo. 2. Deployed demo on a free tier or test server. 3. Short read-me covering setup, AI integration keys, and instructions for adding new templates. When you respond, please outline • The AI service you plan to use and why. • Your preferred tech stack. • Any prior work that shows you can wire a text-generation API into a front-end editor. • Your fee and proposed milestone schedule. I’m ready to start as soon as we agree on the approach.
