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.

Featured On
Lucius AI is a compliance-first risk engine for bids and procurement. It reads 100+ page PDFs into compliance matrices, flags ‘Killer’ disqualifiers via clause-vs-clause contradiction detection, and drafts the full bid in 1M-context. Every finding traces back to the exact page in the source PDF, auditable for legal review.
Don't just write bids. Audit them with page-cited evidence before you commit a week of writing time.
Accuracy by design
Safety-first architecture.
AI hallucinations are a dealbreaker in high-compliance industries. That's why every citation is checked against the source document before it reaches you.
1. Ingestion
Our primary AI model reads the whole document in one pass. It does not chunk or summarize. It reads every single page.
2. Validation
Every extracted requirement is checked back against the source text, deterministically. A quote that does not appear on its cited page does not ship.
3. Output
You get a citation-backed forensic audit trail. Every row links back to the exact page number in the PDF.
The losses
The ways teams lose bids
before they even submit.
Three failure modes account for most disqualified bids, and Lucius catches every one of them before the document leaves your team.
The "False Start"
Pain:
"Missed the compulsory site meeting on Page 2?"
Lucius Solution:
Lucius flags specific dates and mandatory attendance requirements instantly.
The "Commercial Risk"
Pain:
"Disqualified for 99% Local Content rules?"
Lucius Solution:
We scan deep into Annexures to find 'Local Production' clauses buried on Page 140.
The "Pricing Error"
Pain:
"Missed a line item in the 200-page Bill of Quantities?"
Lucius Solution:
Automated BOQ extraction ensures you price every single item.
See it write
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. We made that impossible.”
