Meet the Brains of Wootz: Why Our Hybrid RAG+CAG AI Matters for Aotearoa's Startups
How our cache-augmented and retrieval-augmented AI delivers grounded answers for NZ founders, covering bicultural invoicing and live GST questions.

Speed is good, but accuracy is everything. Here is how Wootz built a hybrid AI that knows New Zealand tax, respects bicultural invoicing and answers your live accounting questions from your own data.
Why generic bots miss the mark in NZ
Most AI chatbots are generalists. They skim the surface of everything, but they do not know your ledger, your IRD history or how to present a bicultural invoice that aligns with the tikanga of your customers. That disconnect creates slow responses, made-up answers and compliance risk.
What is CAG? Your always-on knowledge cache
Cache-Augmented Generation is the assistant's long-term memory. We preload it with the essentials: Wootz documentation, Māori invoicing standards and stable NZ tax rules. Because that knowledge is cached, you get near-instant answers without a database lookup.
Ask, “How do I toggle to a te reo Māori invoice?” and CAG responds in milliseconds with the exact steps.
What is RAG? Your live, grounded data fetch
Retrieval-Augmented Generation is the active research mode. When you ask, “How much GST did I pay last month?” RAG securely pulls the numbers from your database, grounds the response and gives you a precise answer instead of a guess.
How the hybrid works inside Wootz
- Detect intent: The assistant routes informational requests to CAG and data questions to RAG.
- Blend responses: Outputs combine cached guidance with live figures, so you get context and numbers in one reply.
- Check compliance: Guardrails check answers against IRD rules and bicultural invoicing standards before anything is shown.
Why this matters for your bookkeeping
- Grounded answers: Replies are based on verified guides and your actual data, which greatly reduces the risk of made-up figures. Always review anything you file.
- Instant support: Cached knowledge delivers fast how-to guidance when you are mid-task.
- Bicultural intelligence: It understands the difference between standard and bicultural invoices.
- Migration help: It guides you through imported data as it lands when you move from Xero or another system.
Real scenarios Kiwi founders solve
- Switching invoice language between English and te reo Māori, with tax details intact.
- Checking last month's GST paid and received before filing, with live numbers summarised instantly.
- Moving from Xero and asking, “Did all my supplier balances import correctly?” while the AI traces any gaps to the source transactions.
The Wootz promise
We built Wootz to be local by local. By integrating RAG and CAG, we are giving Kiwi startups accuracy usually reserved for much larger firms, priced from $12/mo + GST. It is accounting that speaks your language and knows your data.
