Frequently asked questions

Find answers to common questions about the Knowledge Base, security, and getting started. Still have questions? Talk to our team!
What types of proposals can Cassidy help with?

Cassidy automates responses for RFPs, RFIs, RFQs, security questionnaires (SIG, CAIQ, HECVAT), DDQs, and more. If it involves pulling from past responses and approved content, Cassidy can help.

What file formats does Cassidy accept?

Cassidy ingests RFPs and questionnaires in any format—Word, PDF, Excel, CSV, or directly from procurement portals. Your content library works the same way: sync documents from SharePoint, Google Drive, Confluence, OneDrive, and more. Cassidy keeps everything up to date automatically as files change at the source.

How does Cassidy generate proposal responses?

Cassidy shreds your RFP into individual requirements, searches your content library for matching answers, and generates first-draft responses with citations to source material. Your team reviews and refines—rather than starting from scratch.

How does Cassidy find the right answers if the question isn't worded exactly like one we've seen before?

Cassidy uses semantic search—not keyword matching—so it understands the meaning behind each question and finds relevant content even when the wording is different. It pulls from multiple sources: your approved answer library, legal-reviewed language, past proposals, case studies, CRM data, methodology docs, and even live web research when needed. The result is a response grounded in your best content, not a rigid one-to-one match.

Can Cassidy learn our company's tone and terminology?

Yes. Cassidy pulls from your past proposals, case studies, and approved content to generate responses that match your voice and win themes. You can also define explicit instructions, style guidelines, and terminology rules so every response stays on-brand.

Can I customize responses based on industry, product line, region, or language?

Yes. You can configure Cassidy to tailor responses by industry, product, geography, or language—adjusting tone, compliance language, SLAs, and feature details automatically based on the context of each bid.

Can Cassidy output responses into our branded templates?

Yes. Cassidy can generate responses formatted to match your branded proposal templates, ensuring consistent styling, headers, and layout across every submission.

How does Cassidy keep our content library up to date?

Cassidy syncs with your document sources—SharePoint, Google Drive, Confluence, and more—so your Knowledge Base always reflects the latest versions. You can also flag outdated content for review.

How does Cassidy route sections to SMEs for review?

Cassidy automatically assigns sections to the right reviewers—security, legal, product, finance—based on topic. It tracks sign-offs, follows up on outstanding reviews, and compiles feedback into a single version-controlled draft.
