RFP.ai vs RFP Stack

RFP.ai drafts answers to RFPs, due diligence questionnaires, and vendor assessments using approved source material. It extracts questions, produces cited answers with confidence scores, and sends uncertain responses to subject matter experts. Teams can track coverage, export responses, and fill detected answer fields in the source document. It accepts PDF, Word, Excel, and image files, including scanned documents processed with OCR. Exports include Word, PDF, Excel, CSV, and PowerPoint. Connections include Slack, Microsoft Teams, API access, Claude Desktop through MCP, and a Chrome extension for portals such as SAP Ariba, Coupa, Google Forms, and Microsoft Forms. It is available on the web, as an extension, and through an API. The Starter plan is €49 a month, or €40.83/mo billed annually; the Single RFP Pack is 39.00 EUR as a one-time payment. A 7-day trial is available, but there is no free plan. RFP.ai says customer content is not used to train AI models and core application storage is primarily hosted in the EU. It retains data for 30 days after account cancellation for export, and says it is not currently independently certified, including for ISO 27001.

RFP Stack is a web platform for managing requests for proposals, from intake through drafting and export. It accepts PDF and DOCX files and extracts requirements, attachments, deadlines, and evaluation criteria. Requirements can be classified as MUST, SHOULD, or INFO, then mapped to proposal sections. AI-assisted drafts draw on company profile context and approved library content, with TODO flags and tone controls. The content library indexes approved answers and boilerplate for semantic reuse and insertion into sections. Teams can track RFPs in list or board views, assign section owners, review work, score responses, manage approvals, and record submission outcomes. Readiness checks are available before exporting DOCX, PDF, or ZIP bundles. The site describes SOC 2 Type II compliance, organization-scoped data, controlled access to protected object storage, and logs for AI token use, activity, exports, and submissions. The Free plan has 5 RFPs per month, 100K AI tokens, 100 MB storage, and 2 team members; each RFP project counts toward its limit. A 14-day trial provides full access without a credit card.
