Thailand Legal Digital Platform
AI Lawyer
SiamDisai is a digital platform for Thai law. We serve local enterprises, law firms, government agencies and cross-border investors with legal consultation, contract review, enterprise search and BOI assessment — backed by hundreds of Thai statutes, 2M+ enterprises and all 491 BOI activities.
From 'asking a lawyer'
to 'deciding with certainty'
Thailand is one of Southeast Asia's most interesting markets — and one of the trickiest legal environments. Foreign Business Act, BOI, sector licenses, labor law, tax, PDPA … any one of them can stall an otherwise viable project.
You used to have two options: pay hundreds of dollars per hour for a lawyer, or piece together answers from Google and generic AI. The first is expensive, slow and person-dependent; the second hallucinates, lacks citations and cannot be trusted.
We are building a third option — package Thai law as a trustworthy knowledge base so AI can answer with clause-level citations, review your contracts and produce your reports, giving every Thailand-related key decision a defensible trail.
What we believe
Decision-oriented
Not just 'what it is' but 'should you do it, what's the risk, what's next'. Answers must land on a decision.
Traceable & trustworthy
Every conclusion points to source statute text — no citation, no answer. This is the biggest difference from generic AI.
Local depth
Thai law is not English law translated — we build for Thai law itself, covering Thai-original statutes, case law and the Royal Gazette.
Tech stack behind the certainty
216 Thai statutes — RAG knowledge base
Covers 18 domains: tax & customs, BOI, corporate & investment, industry regulation, food/drug/environment & health, transport & logistics, judicial procedure & codes, finance/securities/trust, labor & SSO, data & cyber, real estate & construction, consumer protection, IP, immigration, anti-corruption & AML, trade competition & antitrust, environment, and insurance. New laws indexed within 7 days with clause-level diffs; daily crawl of the Royal Gazette.
Stance-based contract review pipeline
Not just clause-by-clause issue spotting — we argue from your side, surfacing redlines and negotiation points based on Thai law, industry practice and 2M+ enterprise data.
2M+ enterprise database
Public DBD registrations + ~3K added daily. Shareholder traversal, TSIC mapping, Chinese-name aliases. Bulk API plugs into diligence and KYC pipelines.
Trilingual native
ZH / EN / TH share the same knowledge base — cross-border and local teams use one tool, no translation hops.
Public × private hybrid
We maintain the L0 statute base; contracts and enterprise data (L2) stay on customer servers; TLS 1.3 connector in between; Mode A/B/C tiers match different compliance needs.
