In their own words
Winify AI
Winify AI helps teams prepare responses to requests for proposals and similar bids. It is aimed at small businesses, government contractors, and public-sector suppliers that need compliant bids without a full proposal department or heavyweight enterprise software. It supports public-sector RFPs, RFQs, solicitations, and bid packets, as well as similar commercial proposal work. After upload, it organizes mandatory requirements, red flags, forms, attachments, deadlines, submission instructions, and response sections into a checklist. Users can add past proposals, service descriptions, case studies, and internal documents to the Knowledge Hub so drafts draw on approved material. The service generates first drafts against the checklist for teams to review and refine before assembling a response package. Uploads support PDF, DOCX, and spreadsheets. A free Starter Trial has no time limit and includes one bid packet, up to 50 pages per packet, and 100 Knowledge Hub pages. Paid plans start at $49.99 a month. The service includes AI drafting, a content library, and a collaboration workspace.
