Works where your team already works
Lucius fits the tools bid teams live in, instead of asking them to move.
Microsoft Word
Check any draft against the tender's requirements from a side panel inside Word, while you write.
SharePoint
Import your past bids straight from a SharePoint library, so drafts draw on what your team has already won.
Email, Word & Excel out
Matching tenders land in your inbox; every analysis and draft exports to DOCX, XLSX and PDF for the rest of the business.
What Lucius actually catches
Two real runs on public tender documents, straight from the product.
US Army Reserve Design/Build RFP · 91 pages
184 requirements
173 verified word-for-word against the source text. Deep Review also flagged the same contract line number assigned to two different work items, the kind of conflict that invalidates a priced schedule and that a checklist read misses.
NHS Standard Contract 2024/25 · Service Conditions
354 requirements
Every one cited to its page and clause, so a bid team can open the exact passage instead of trusting a summary. Nothing is invented; anything Lucius cannot ground in the document is flagged, not filled in.

Lucius reads a full tender pack into a compliance matrix, flags the clauses that can disqualify a bid, including where one section contradicts another, and drafts the response from your own past bids. Every finding traces back to the exact page in the source PDF.
Audit the tender before you commit a week of writing time.
Nothing invented, everything cited
An invented citation is a dealbreaker in regulated procurement. Every finding is checked against the source document before it reaches you.
1. Read
Lucius reads the whole document in one pass. No chunking, no summarising. Every page, including the annexes.
2. Verify
Every extracted requirement is checked back against the source text. A quote that does not appear on its cited page does not ship.
3. Cite
You get an audit trail you can defend. Every row links back to the exact page number in the PDF.
The ways teams lose bids
before they even submit
Three failure modes account for most disqualified bids. Lucius reads for all three before the document leaves your team.
The missed site meeting
A compulsory briefing on page 2 goes unread, and the bid is over before it starts. Lucius flags every date and mandatory attendance requirement up front.
The buried clause
A local-content or eligibility rule sits in an annexure on page 140 and disqualifies the whole submission. Lucius reads the annexes as carefully as the front matter.
The unpriced line item
One row missed in a 200-page bill of quantities breaks the whole priced schedule. Lucius extracts the BOQ so every item gets a price.
From tender to draft,
in your voice.
Lucius reads your bid library, weights your wins, and drafts the next proposal, section by section.
“We built Lucius because reading a 500-page tender shouldn't take a week. One missed clause costs more than a year of subscription. That read is what Lucius does, every time, with the citations to prove it.”
