Engineered Specifically for UK Tender Writing Agencies
Generic AI chatbots hallucinate case studies and fail public sector moderation. BidPen combines strict schema enforcement with isolated agency workspaces.
Zero-Hallucination Evidence Guardrails
Never risk tender disqualification due to fabricated contract values or invented ISO certificates. When an ITT question asks for a metric not present in your prompt, BidPen inserts a prominent [PLACEHOLDER: ...] and builds an itemized checklist at the top of your Word document.
[PLACEHOLDER: Confirm exact Carbon Reduction Plan PPN 06/21 baseline year & Scope 1/2 tCO2e figures]
