Catch the disqualification before you submit.
Every year hundreds of 나라장터 bidders are cut not on their proposal but on the package — a missing document, a mismatched name, a price over budget. Miriboa checks your bid against what the notice actually requires, before submission, so a paperwork slip doesn’t cost you the tender.
First verification free · 1 credit ₩290,000 = up to 3 runs of one notice until it closes · Buy credits →
Bids die on paperwork before they are ever scored.
We tallied six months of public bid-opening data from Korea’s national e-procurement system (나라장터) — every negotiated-contract service tender opened between January and July 2026: 32,319 notices, 68,912 bids, 12,796 participating companies. Hundreds of those companies were disqualified not on the strength of the proposal, but on the package itself — every one a defect type Miriboa checks before you submit.

Requirement extraction
Requirements are pulled from the tender package — tables included — into a structured, reviewable checklist.
Compliance check
Your bid is matched against each requirement. Gaps and deviations surface before submission — not after a rejection.
Mandatory-document check
The required-documents list is extracted from the notice and checked against your package — a missing form surfaces before it disqualifies you.
Cross-document consistency
Company name, representative, and dates are compared across every document in the package — a stale year or a mismatched name gets flagged.
Price consistency
Line items are summed against totals and checked against the stated budget — arithmetic slips and budget overruns are caught before submission.
Grounded, machine-certain findings
Each finding is grounded in the source text. Only high-certainty results are marked certain; the uncertain are isolated for a human.
The LLM proposes. A deterministic layer decides.
Miriboa never lets a language model have the last word. Extraction and judgment are proposed by AI, then confirmed by a deterministic layer that scores certainty and grounds every finding in the source.
- 01
Parse
HWP/HWPX, PDF, DOCX and XLSX packages are parsed and normalized — tables preserved, not dropped, including the requirements most parsers lose inside HWP tables.
- 02
Extract requirements
The AI proposes the requirement set; a critic pass filters it into a structured golden checklist.
- 03
Judge compliance
Each requirement is checked against the bid and graded — machine-certain, or needs-review.

Report
A pre-submission report lists met, missing, and deviating requirements, each grounded in the source.
Measured in July 2026 on an internal golden set of 173 requirement items. The tender notices are real and published; the bid packages are synthetic, written for the benchmark. These figures describe benchmark performance and are not a guarantee of results on your own documents.

Miriboa is a vendor-operated verification service: you send the tender and bid package, we run the verification, and you get the report back — nothing to install, nothing to integrate. Your first verification is free (a sign-up credit); after that one credit is ₩290,000 and covers up to 3 runs of the same notice until it closes — so the package you finally submit is the one that got checked.

Reading a notice is not the same as proving your package meets it. The paid verification does the exhaustive cross-check the free tools skip — every required document matched, line-item prices summed against the budget, names and dates reconciled across the package, each result cited — reviewed by a person, on your deadline.
Before you send — freeBefore that, the reading half is free and self-serve: our Claude connector searches 나라장터 notices and reads 공고문 and 과업지시서 with tables intact, so you can pull out the deadlines, required documents and scoring yourself. Add the Claude connector →
Miriboa checks documents against a notice’s stated requirements. It is not legal advice, not a legal determination of eligibility, and not a guarantee of winning or passing evaluation — final responsibility for your submission is yours.
