The verdict in three sentences
A custom EU-hosted AI meeting minutes tool costs EUR 10,000 to 25,000 excl. VAT to build in Berlin in 2026, plus EUR 0.5 to 2 per hour of processed audio. For a corporate secretariat handling 120 leadership meetings a month, the investment pays back in 8 to 14 months thanks to 3 hours saved each week per assistant. The real challenge is not transcription, which is now a commodity, but data control: location, retention period, access rights and the GDPR record of processing.
Why consumer tools are a problem for a leadership team
Meeting assistants built into US video platforms work well, but they often send audio to servers outside the EU, keep data to train their models or do not allow automatic deletion. For meetings covering restructuring, compensation or acquisitions, that is a legal risk (GDPR articles 44 to 49 on transfers) and a confidentiality risk, which German works councils (Betriebsrat) also scrutinise closely.
A controlled solution relies on four building blocks: a transcription model hosted in Germany or France, a summarisation model deployed with a European provider, encrypted storage with configurable retention, and an interface that plugs into the existing calendar and intranet.
| 2026 option | Upfront cost | Recurring cost | Data location | Retention control |
|---|---|---|---|---|
| Assistant built into video platform (US offer) | EUR 0 | EUR 20 to 35 / user / month | Often outside EU | Limited |
| European transcription SaaS | EUR 0 to 2,000 | EUR 15 to 40 / user / month | EU | Partial |
| Custom solution, EU-hosted model | EUR 10,000 to 25,000 excl. VAT | EUR 0.5 to 2 / audio hour + EUR 150 to 400 / month hosting | Germany or EU, contractual | Full (30, 90, 365 days) |
| Self-hosted model on dedicated GPU server | EUR 25,000 to 45,000 excl. VAT | EUR 600 to 1,500 / month | Your premises or German datacenter | Full |
| Manual note-taking by an assistant | EUR 0 | 45 to 60 min per meeting | Internal | Manual |
What a EUR 10,000 to 25,000 budget covers
The range mainly depends on the number of integrations and how structured the minutes must be (simple summary or a decision log with owners and deadlines).
| Item | Essential version | Full version | Indicative timeline |
|---|---|---|---|
| Scoping, impact assessment (DPIA) and GDPR record | EUR 1,500 | EUR 3,000 | 1 to 2 weeks |
| Transcription pipeline + speaker identification | EUR 2,500 | EUR 5,000 | 2 weeks |
| Structured summary (decisions, actions, deadlines) | EUR 2,500 | EUR 6,000 | 2 to 3 weeks |
| Outlook or Google calendar + intranet integration | EUR 1,500 | EUR 4,500 | 1 to 2 weeks |
| Access rights, logging, automatic deletion | EUR 1,500 | EUR 4,000 | 1 to 2 weeks |
| Acceptance testing, assistant training, documentation | EUR 500 | EUR 2,500 | 1 week |
| Total | EUR 10,000 excl. VAT | EUR 25,000 excl. VAT | 6 to 10 weeks |
In operation, one hour of meeting consumes EUR 0.5 to 2 depending on the model and the length of minutes required. With 120 meetings averaging an hour and a half, the usage bill stays between EUR 90 and 360 a month, hosting included at the top of the range.
Compliance points to lock down
German and EU regulators expect a clear legal basis (legitimate interest of the organisation, with prior notice to participants), a proportionate retention period and an impact assessment when sensitive data may come up. In practice you need a notice when recording starts, the ability to pause capture, automatic deletion of raw audio once minutes are generated (often 7 to 30 days) and a data processing agreement (article 28) with each provider. In Germany, involving the works council early avoids a blocked rollout. Clauses forbidding reuse of data for model training must be written explicitly.

Katrin, corporate secretary of a 900-employee services group in Berlin, coordinates 4 executive assistants. Each spent about 50 minutes per set of minutes. After deploying a EUR 18,000 solution, drafting drops to a 15-minute review. Measured gain: 3 hours per week per assistant, 12 hours a week for the team, roughly 530 hours a year. At a loaded cost of EUR 38 per hour, that is EUR 20,140 a year. Minus EUR 3,000 of annual usage and hosting, the net gain reaches EUR 17,140: payback in 12.6 months, and minutes circulated the same day instead of 3 days later.
FAQ
Can we guarantee no data leaves the European Union?
Yes, provided you choose EU-hosted model providers with a contractual location commitment and exclude any sub-processing outside the EU. The premium over a US offer is around 10 to 30% on usage.
What transcription accuracy can we expect in German or French?
With decent microphones, the word error rate sits around 5 to 8% in 2026, and the summary corrects most approximations. Proper names and internal acronyms improve with a glossary of 100 to 300 terms.
How long should recordings be kept?
Recommended practice is to delete audio within 7 to 30 days and keep approved minutes under the archiving policy, often 3 to 5 years for leadership bodies.
Do we need a DPIA?
It is strongly recommended as soon as processing covers recurring meetings likely to touch HR or health data. Budget EUR 1,500 to 3,000 excl. VAT if included in the project.
Must external participants be informed?
Yes, every participant must be notified before recording, and a no-capture mode must remain available for sensitive items. An automatic line in the invitation covers 90% of cases.
