  • Answers from the contract you have open
  • Cites only the law it actually found
  • Personal details masked before the AI reads them

The assistant answers in Thai. The example is shown as it appears in the app.

Ask about any part of the contract, in your own words

Type your question the way you would ask a friend. Kontrax AI reads the contract you have open, points to the clause that answers it and explains what the law says. The sections it used are listed under every answer.

Each question 1 token

Check it before the other side signs

Press check. The system goes through the figures and choices you filled in against the law, then tells you what to fix before sending and what to look at again, with a suggestion and the sections that apply.

Each check 3 tokens

Personal details masked every time, before anything reaches the AI

Before any text leaves our system for the AI, names, addresses, ID numbers, phone numbers and other personal details in the contract are masked. The AI refers to the parties by role, such as landlord and tenant, and you never need to type those details into a question.

Open it at every step of a contract

Open Kontrax AI from any page where you work on a contract, and it reads that contract straight away.

Common questions

What is Kontrax AI? Can it replace a lawyer?

Kontrax AI is the contract assistant on the drafting and signing pages. Ask about any clause of the contract you have open, or have the draft checked before you send it to the other party. Answers cite only Thai law the system actually found, from the Civil and Commercial Code, specific acts and Supreme Court decisions, with points from a lawyer's checklist. Personal data is removed before anything reaches the AI. The answers are general explanations to help you understand, not legal advice; if there is a dispute, consult a lawyer. Every Pass includes starter tokens, and you can top up.

Where do the legal references come from?

Only from Thai law the system actually found, from the Civil and Commercial Code, specific statutes and Supreme Court decisions. The sections it used are listed under every answer, and when nothing relevant turns up the assistant does not cite a section of its own.

Is the personal data in my contract sent to the AI?

Before any text leaves our system, names, addresses, ID numbers, phone numbers, e-mail addresses, bank account numbers and other personal details are masked and replaced with [ปกปิด] (masked). The AI refers to the parties by role, and you do not need to type those details into a question.

What is a token and how is it used?

Tokens are what Kontrax AI runs on. A question costs 1 token and a contract check 3. A new account gets 4 tokens for 7 days, Pro Pass comes with 20 and Team Pass with 150 shared by the team, for as long as the plan runs. Top-ups start at ฿28.

Which contracts does it work with?

Any contract you draft, review or receive for signing in Kontrax, such as leases, employment and freelance contracts and NDAs, and also when you amend or end one.
