Works with Claude & ChatGPT
Legal research and drafting on Claude and GPT
Ask GST questions in plain English. Get research backed by the exact law, circular, notification or source page inside your AI assistant.
Why TaxByKK is different
Confident is not the same as correct.
The same question, put to a general chatbot and to TaxByKK.
The question
“ITC for FY 2019-20 was claimed on 31.10.2022. The notice says it is time-barred under Section 16(4). Is there any way out?”
Under the hood
Our own reasoning engine.
Reads whole documents, across tens of thousands of them, without the cost of feeding them to a model.
A provision means nothing without its proviso, its amendment history and the circular that reads it down. We keep the document intact.
TaxByKK connects to the Claude or ChatGPT subscription you already pay for, so frontier-model reasoning costs you nothing extra.
Our retrieval cost barely moves as the library grows. Raw input does not stop climbing — and past a point it will not fit in the model at all.
