AI an auditor
can sign.
Regulated work needs the judgment of a language model and the reliability of a calculator. GraphBit refuses the trade-off: the model reasons, a deterministic engine governs — every decision grounded in codified law, every step traceable years later.

Explain this decision to an auditor.
Three years later.
Generic GenAI
Reads the contract, understands the context — and hallucinates. Same input, different output. In regulated work, a one-percent error rate is not a rounding issue. It is a legal liability.
Rule engines
Perfectly deterministic, perfectly blind. They confirm the rate and the arithmetic. They cannot read a contract and tell you whether the transaction is what it claims to be.
Human experts
The only ones who can judge meaning — at minutes to hours per document, against millions of documents a year. So the work gets sampled. Most of it is never examined at all.
Read the meaning, or be deterministic. Every existing approach picks one. GraphBit is built to do both.
The model reasons. The engine governs.
Codified law, mapped per jurisdiction into a proprietary graph. The unalterable source of legal truth — versioned, dated, and cited on every decision it touches.
Isolated LLMs read what only language models can read — contracts, logistics, correspondence — and reason only through the graph's guardrails. Good at meaning. Trusted with nothing that carries risk.
A Rust-native engine governs every step, route, and tool call. Same input, identical output, every time. The model can interpret context. It can never guess a rule.
One engine, applied where being wrong is expensive.
GraphBit is the deterministic core. Tax Solutions and Document Intelligence point the same engine at a different corpus — the guardrails, the record and the reproducibility are identical.
GraphBit
A Rust-core execution engine for AI workflows that have to survive an audit. The model reasons inside hard guardrails; it never routes, and it never decides a rule.

“We didn't choose deterministic AI because it's the safe option. We chose it because it's the only architecture whose decisions we can explain even years after they were made — to our clients, to an auditor or to an authority.”
Jewgenij TarschisGrant Thornton Germanypublic statement · 2026The law has set the clock.
National e-invoicing mandates, then EU-wide digital reporting under ViDA, put every transaction permanently into the authorities' hands — cross-matched, retroactively queryable, impossible to withdraw.
Wherever AI touches regulated decisions, the AI Act requires auditability, reproducibility, and human oversight. Companies won't be asked whether they want compliance-grade AI. They'll be asked to prove they have it.
Whatever you file becomes evidence, forever. Validation has to happen before filing — at 100% of volume — and your auditors will ask how you did it.
We didn't just meet the German standard for AI in tax and audit. We helped write it.
InfinitiBit co-authored the DIN SPEC that defines what deterministic, auditable AI has to look like in tax, audit, and finance. When your auditors ask what “compliant AI” means, the answer cites work with our name on it.
See it on your own transactions.
We don't do slideware demos. Bring a sample of your real documents — contracts, invoices, filings — and watch the engine validate them, trace and all. Two hours, your data, our architecture.
