Legal work is slow where every source is searched and read one by one
One set of facts can touch several Acts and hundreds of rulings, while paper contracts and English contracts are still typed and translated by hand.
A keyword search misses, because the facts do not use the statute’s words.
01Search sections and rulings
Describe the situation and get the sections that govern it and the rulings by headnote, or fetch a case by its number.
0.1 credits a request, free during the launch
Many sources to read before one client question is answered.
02Answers with sources
OpenThai 2.0 Legal answers Thai legal questions citing the sections and rulings it used, so a lawyer can check each source straight away.
0.01 / 0.02 credits per 1,000 tokens
Paper contracts and English contracts, typed and translated by hand.
03Read and translate contracts

Before you decide, you will want to know this
Every answer comes from the API documentation and the published measurement.
Can it replace a lawyer?
No. It is a tool for searching and drafting; every answer cites the sections and rulings it used, and a professional should check those sources before relying on it.
Does it work with Claude or other AI assistants?
Yes, through iapp-mcp: the assistant searches the law, fetches sections and fetches rulings by itself.
What will it cost after the launch?
0.1 credits a request, before VAT. The list of laws and the metadata stay free.
How long does integration take?
One HTTP POST, with examples in curl, Python and JavaScript, and an open-source SDK for web and apps. Try it on the free credits before you write production code.
Can we get a tax invoice in our company’s name?
Yes. Request it from the credits page of your account after you pay.
