Who it is built for, and where it is not.
Why Audact
One receipt per governed interaction.
Every platform in this market can hold a conversation. The question a regulated buyer actually asks is a different one: when this call is disputed in eight months, what do you hand over? Audact answers that with an artefact rather than a policy. A receipt is visible in the product for governed interactions. The input hash, the output hash and the link to the receipt before it can be recomputed by anyone: without a key, without an account, and without access to our systems.
The distinction
A promise and a receipt are not the same object.
There are two ways to answer the compliance question. One is process: a pledge to scrub a do-not-call list, a quality review after the call, an indemnity clause in the terms. All of it describes what should have happened. None of it shows, on one specific call, that it did.
Audact answers it with the record. The AI disclosure is spoken at the position the country policy requires, the approved wording is checked before the model speaks rather than sampled afterwards, and both leave a trace in the same artefact. When something is disputed, a promise is an argument and a receipt is a document. Status: In controlled testing. Germany active · Netherlands in progress · Belgium, Austria queued.
Where we sit
Agency-native, with the artefact on top.
We match the agency-native shape on the things that make a reseller's life work: white-label the caller actually hears, isolated sub-accounts, transparent per-minute pricing, and billing that routes to your Stripe rather than ours. Stripe re-billing: Planned.
What is added on top is the part that is hard to bolt on afterwards, because it has to sit in the path of the call rather than beside it. Both leave the same receipt, which is what turns a claim into something an end-client's data protection officer can open and check; the monthly evidence package that goes with it is not in the offer; it is Under validation: we do not ship an evidence artefact we have not tested ourselves. What sits in the path of the call today: the disclosure is enforced at the moment it is due, and the approved wording, the prices and the commitments the agent may make are checked before the model speaks.

The fields
What a third party can recompute, and why that is the whole point.
- The input hash: what went into the model on this turn.
- The output hash: the output the gate released (on a block, the fallback reply).
- The link to the receipt before it: so a later alteration or reordering is detectable.
- Merkle inclusion, so a single receipt can be tied to a published commitment. The fourth, inclusion in the Merkle root, is checked against the published root with the inclusion proof from the call's Article 50 report; the roots are published at api.audact.ai/v1/metachain. The three above it you can run right now.
Questions
- Why is this different?
- Because compliance is a statement and evidence is an object. Article 50 requires the disclosure; it does not require proof that you gave it. That gap only matters at one moment: when someone asks. And at that moment the difference between a statement and an artefact is the whole conversation.
- Does that mean the law requires an evidence chain?
- No. Point (73) of the Commission guidelines of 20 July 2026 says a full provenance chain is not mandatory, and we do not claim it is. The law sets the minimum; your client may still ask what actually happened on a call in March. The day you need that record is the day it can no longer be created.
- Can I see one before I commit to anything?
- Yes. The receipt explorer takes a receipt and recomputes the public fields in front of you, with no account and no key. Three of them settle against the receipt itself; the fourth, inclusion in the Merkle root, is checked against the published root with the inclusion proof from the call's Article 50 report. It is the same artefact a live call produces.
Look at a receipt first
Take one, recompute the fields yourself, and then decide whether the rest of the argument holds. That order is deliberate.
