NOMOS is a Microsoft Word add-in for Colombian lawyers. It does two things inside the document they already write in: it verifies every legal citation against the official text of Colombian law (green = real, red = doesn't exist), and it drafts in Colombian legal Spanish grounded only in real, cited authorities.
The verification is deterministic — it checks each citation character-by-character against a database of official law, not an AI guess. That is the moat: every competitor generates text and "hopes" the citations are real. We prove they are. We do this at the exact moment Colombian courts have started fining lawyers and annulling rulings for AI-fabricated citations.
Generative AI invents articles and court decisions that don't exist — with real-looking numbers, dates and magistrates. In Colombia this stopped being theoretical in the last 12 months:
Every fabricated citation is now a fine, a nullity, and a disciplinary file waiting to happen. Lawyers need a safety net — and none of the tools they're using is one.
Not another tab, not another chatbot. A task pane beside the document the lawyer is already drafting in Word — the tool 90%+ of legal work happens in.
Powered by DeepSeek V4 Pro for drafting and a deterministic engine for verification. Confidential by design: verification runs against the corpus with no model in the loop; only the drafting step calls the AI.
Colombia's legal-AI market is real (#2 in Latin America) — which proves demand. But every player is a generative/RAG tool that surfaces "source links" and still hallucinates. The leader, Magnar (Chilean, $800k raised), says minimizing hallucinations is an unsolved challenge in its own founder's words. None of them verify that a cited article or ruling actually exists.
| Magnar / Ariel / vLex | NOMOS | |
|---|---|---|
| Approach | RAG — generates + links | Deterministic — proves it exists |
| Hallucinated citation | can still slip through | flagged red, always |
| Lives in Microsoft Word | mostly separate apps | yes — in the document |
| Confidentiality / on-account | cloud RAG over your files | verification needs no model |
The one sentence no competitor can say, at the worst possible moment for them not to: they minimize hallucinations; NOMOS makes them impossible to file.
A saturated, hyper-competitive bar (≈40% can't find legal work) means maximum pressure to adopt AI to compete — and maximum exposure to the hallucination risk the courts are now punishing. 62% of Colombian firms with 5+ lawyers already pay for an AI tool. The buyers exist; they're just buying tools that don't protect them.
The product's cost structure is almost pure margin. Verification costs nothing (deterministic). Drafting on DeepSeek V4 Pro costs under one cent per document. Microsoft takes nothing — AppSource listing is free, and billing through Stripe means a 0% Microsoft fee.
| Per seat / month | Amount | Note |
|---|---|---|
| Subscription revenue | $100.00 | per lawyer |
| DeepSeek V4 Pro (drafting) | −$1.00 | ~0.1¢/draft; <$2 even at 1,000 drafts/mo |
| Citation verification | −$0.00 | deterministic — no model |
| Microsoft Word / AppSource | −$0.00 | free listing, 0% via Stripe |
| Payments (Stripe) | −$3.20 | 2.9% + $0.30 |
| Infrastructure | −$0.10 | serverless, amortized |
| Gross profit / seat | ≈ $95.70 | ≈ 96% margin |
| Seats | % of market | MRR | ARR | Gross profit/yr |
|---|---|---|---|---|
| 100 | 0.02% | $10,000 | $120,000 | ~$115,000 |
| 500 | 0.12% | $50,000 | $600,000 | ~$575,000 |
| 1,000 | 0.24% | $100,000 | $1.2M | ~$1.15M |
| 5,000 | 1.2% | $500,000 | $6.0M | ~$5.7M |
| 10,000 | 2.4% | $1.0M | $12.0M | ~$11.4M |
Capturing just 2.4% of Colombia's lawyers = $12M ARR at ~95% gross margin. The serverless, $0-Microsoft, sub-cent-AI cost structure means scaling adds margin, not overhead.
The hard, defensible asset — the corpus and the verification engine — already exists:
Remaining: package the Office.js Word add-in, expand the corpus (Council of State + Supreme Court case law, all national statutes — all public and free), and launch.
Pricing: $100 USD/seat/month, with annual and firm/seat-bundle options. Premium-but-justified: one avoided sanction pays for years.
