Tender responses built on your own evidence.

BidVault is an AI bid-writing platform for UK suppliers competing for public sector contracts. It turns your company's policies, case studies and accreditations into compliant tender responses, mapped to every criterion the buyer will score.

How BidVault works

Upload your company documents once to build a private Knowledge Vault. Paste the buyer's question and evaluation criteria, and BidVault identifies every explicit and implicit requirement, retrieves the matching evidence and drafts a structured response within the word limit. An independent evaluator agent then scores each requirement out of five, rewrites weak sections and checks every claim against your vault. Anything that cannot be evidenced is flagged for you to supply, never invented.

Why BidVault, not general AI

General AI tools know nothing about your company, so they fill the gaps with plausible guesses that can cost marks, or compliance, in a contractual submission. BidVault writes only from your verified evidence, mirrors the buyer's own wording and scoring criteria, and applies current UK procurement guidance, including the Procurement Act 2023 and PPN 002. Every response is scored and audited before it reaches you.
