AI RFP software that drafts proposals inside an opportunity workspace
Each bid gets its own space holding the RFP, forms, company content, analysis output, drafts, and reviews so nothing is scattered across folders.
Breaks long RFP documents into requirements, instructions, risks, deadlines, and response priorities, and builds compliance matrices from them.
Generates first-draft responses in DOCX from the RFP plus your company library, and answers structured RFQ and XLSX forms using approved content and pricing inputs.
Imports past winning proposals, company notes, and rate information to make drafts specific to your organization rather than generic.
