Manual proposal writing is broken.
Proposal teams spend weeks on every RFP, lose deals to faster competitors, and burn out chasing deadlines that never let up.
Weeks of writing per RFP
Average response takes 3–4 weeks of dedicated effort.
Hours stuck in formatting
20+ hours per proposal lost to copy-paste, not strategy.
And you still might not win
Massive effort, low win rates, exhausted teams.
Arthur drafts your full RFP response, end-to-end.
Frontier-model agents parse every requirement, retrieve your best content, write each section, and clear compliance — no template wrangling, no first-draft slog.
Drafts every section
Each requirement, written autonomously by frontier models.
Clears compliance
Catches gaps and risks before you submit.
How BidAuthor Works
From knowledge upload to submission — five steps from blank page to winning proposal.
Upload Your Knowledge Base
Centralize the internal information that runs your company — SOPs, policies, product docs, process notes, and project history. BidAuthor uses it to ground every response in real, current context.
Upload Your Guidelines
Add your proposal playbooks, response rules, approved phrasing, and red flags. Arthur learns how someone on your team would actually answer, then mirrors that voice and avoids the wrong claims.
Upload the RFP
Drop in the live RFP, statement of work, and attachments. BidAuthor extracts every requirement, maps it to sections, flags risks, and pushes the package through your response pipeline.
Generate & Refine the Response
Arthur drafts each answer, tracks live status across the document, and helps your team move every question from in-progress to review-ready — without losing the thread.
Export & Submit the Proposal
Finalize the response, export a polished proposal package as PDF or DOCX, and ship a submission-ready document to your customer with confidence.

Your proposals, knowledge base, and customer data are protected with the same controls Fortune 500 RFP teams demand.
