Free tender compliance checker.

Why a compliance check wins or loses the bid

Public-sector bids are scored against a published set of mandatory requirements. Miss one — a certification, an insurance level, a reporting deadline, a clause you were supposed to confirm — and the answer loses marks or the whole bid is disqualified, no matter how good the prose is. The single most valuable thing a bid manager does is check, line by line, that every requirement is actually answered.

What this tool does differently

Most AI bid tools insert saved answers from a content library. This does the opposite and harder thing: it reads the answer you have actually written and checks it, requirement by requirement, quoting the evidence from your own text for each one it counts as addressed. It will not tell you a requirement is met unless your draft really addresses it, and it never fabricates a requirement that is not in your list.

• Requirement-by-requirement: every mandatory line marked addressed or missing.
• Cited evidence: the exact phrase in your draft that satisfies each requirement.
• Gap list: the requirements you still need to answer, surfaced first.
• Word-limit check: instant count against the buyer's limit.

This free checker works on a single answer against requirements you paste. Inside Lucius, the requirements are extracted automatically from the tender PDF, every answer is checked, and compliant responses are drafted for you — each one cited to the clause it answers.
