Your AI is guessing your taxes. Stop it in one line.
Paste one connector into the AI you already use. From then on it answers tax questions from real, accountant-checked rules — with the actual law cited — and tells you when your situation needs a licensed human.

What you get
Real numbers, real law
Rates, thresholds, and deductions pulled from rules a licensed accountant signed off on — with the actual code section cited. Not a number your AI made up from training data.
It knows when to stop
When your situation needs professional judgement, your AI says so — and hands the worksheet to a verified accountant for your country instead of bluffing through it.
Works in the AI you already use
Claude, ChatGPT, Cursor, Windsurf, and any other MCP-aware client. No new app, no account, no API key. Paste one line and you're done.

What happens once it's on
Three steps from a question to a credentialed human — without you doing anything technical.
- 1
You ask your AI a tax question for your country.
“Help me file my 2025 return — I'm a sole proprietor in South Africa.” Your AI quietly loads the verified rules for your jurisdiction instead of guessing.
- 2
It works through the numbers and shows its sources.
Computed return lines, every assumption flagged, each figure tied to the law — drawn from rules a named accountant signed off on, not hallucinated from training data.
- 3
When you're ready to file, it hands you to a verified human.
Your AI routes the worksheet to the lead accountant for your jurisdiction with a booking link. Nothing is signed yet — it's just a review conversation with a real, licensed professional.
Stop your AI guessing.
Copy the connector, paste it into your AI, and ask a real tax question. Or talk to a verifier first.
