How the AI in VoltType works

Last updated: 27 September 2026 · Privacy policy · Terms

If your supervisor, your data protection officer or a procurement form has asked what the AI in this tool is, this page is the answer. It says what each piece of AI does, where it runs and what it receives. The exact models and versions are listed in our data-processing agreement, which we send on request.

The six AI components. There is no seventh.

What it does	Where it runs	What it receives
Speech to text, on your machine	your own PC or phone, on the processor	audio — never leaves the device
Speech to text, over the internet	Groq, in the United States	the audio, in transit only
The writer on your machine — AI Notes, meeting notes, spoken commands	your own PC, on the processor	the text — never leaves the device
The writer over the internet — the same jobs	Groq, in the United States	the text, in transit only
Telling speakers apart in a meeting	your own machine	audio — never leaves the device
Recognising a voice you have named, in a later meeting	your own machine (Windows)	one saved voice fingerprint per name you typed

Everything else in the product is ordinary code: the punctuation and number rules, the spoken-command tables, the silence gate, the plan counters. Those are tables written by hand, not models.

We use published, open-weight models exactly as their makers released them; we do not build or train models. The names and versions of the models in use are in the data-processing agreement, available on request for a pilot and included with Teams.

Three things we do not do, and one we will not build

We do not detect emotion. VoltType does not judge mood, stress, health, attitude or character from a voice or from words. Checked across all 22 of the writer's instructions and the whole source tree. Inferring emotion in a workplace is one of the AI Act's outright prohibitions, and it is a permanent design ban here, not an oversight we might reverse.
We do not train on anything you say. There is no training or fine-tuning pipeline in the product. Every model is used exactly as its maker published it.
We do not make decisions about people. Nothing here scores, ranks, screens or profiles anybody. The AI turns speech into text and writes drafts from it.
Your words are not stored on our servers. No audio. No transcripts. Our usage table holds counts — seconds, words, which language, which model — and has no column that could hold content.

Voices you name, which is the part worth reading twice

If you type a person’s name next to a speaker in a meeting, the app can keep a voice fingerprint so the next meeting recognises them. This is the most legally significant thing in the product, so here it is in full:

A fingerprint is a list of numbers. It contains no audio and cannot be turned back into a voice or into words.
It is stored only on your own machine, in one file in your own folder. We never receive it. We never see it, hold it or back it up.
Nothing is saved unless you type a name. Without a name a speaker stays “Speaker 1” and no fingerprint is kept.
It refuses to guess: a name is used only on a clear match that also clearly beats the runner-up. Otherwise the speaker stays unnamed.
Under EU law a voice fingerprint is personal data belonging to the person whose voice it is, and a special category at that. The person is usually not you — it is someone else in your meeting. The app therefore asks you to confirm they agreed, and you can delete any saved voice with one tap.

Recording people

VoltType records only when you press record. Everyone in the room must know and agree. In some countries — Germany and France among them — recording a conversation without everyone’s agreement is a criminal offence. The apps ask you to confirm this before your first recording, and say so again on the meetings screen. See section 9a of the Terms.

Where anything leaves the EU

One destination, and only while you are working over the internet: Groq, in the United States, which runs the cloud speech and writing models. Audio and text pass through in transit and are not retained. Your account lives in the EU (Frankfurt). Payment goes to Stripe and account e-mail to Resend. Every one of them is named in the privacy policy, with the transfer safeguards.

With the on-device packs on Windows and Android, none of that happens at all: the audio and the text stay on the machine.

Where we stand on the EU AI Act

Not high-risk. VoltType is a dictation and writing tool. It does not take or support decisions about people, which is what Annex III turns on.
Not a prohibited practice. No emotion inference, no biometric categorisation, no social scoring, no manipulation.
Article 50(2) applies to us and we have started early. Text a machine wrote is marked as machine-written where you see it and in anything you share out of the app. The legal deadline for products already on the market is 2 December 2026; the Android app shipped the marking on 27 September 2026 and the other apps are following.
Article 4, AI literacy. This page is part of how we meet it. If you need something more formal for a procurement file, write to us and ask.
Nothing to register. There is no EU database entry required for a system like this, and we hold no security certifications — we have had no external audit, and we would rather say so than imply one.

If a form asks you for a one-line answer

“An EU-hosted account, one American AI processor used only while online, and everything else on the user’s own machine. No training on user data, no emotion detection, and no audio or transcripts stored by the vendor.”

Every statement on this page was read out of the running system on 26–27 September 2026 — the source, the live database schema and the app’s own model files — not out of a marketing plan. If something here ever contradicts what the product does, the product is what counts and we want to know: [email protected].
