At Vivatech 2025 in Paris, csky.ai and DuoKey introduced a secure AI transcription solution integrated with Microsoft 365, designed to safeguard confidential meeting data. By combining csky.ai’s offline AI transcription with DuoKey’s Double Key Encryption (DKE), this solution ensures organizations can transcribe sensitive discussions while maintaining strict data privacy and compliance in the Microsoft cloud.
csky.ai and DuoKey launch secure AI transcription for Microsoft 365 at Vivatech.
Offline processing via csky.ai’s ClearMind device keeps audio on-premises.
DuoKey’s Double Key Encryption secures transcripts in Microsoft 365.
Solution supports GDPR, HIPAA, and CCPA compliance for sensitive data.
Real-time transcription generates enterprise-grade meeting minutes.
Ideal for legal, healthcare, and financial sectors handling confidential data.
The solution leverages csky.ai’s ClearMind device, which processes transcriptions offline using a local large language model, eliminating the need for internet connectivity. This edge computing approach ensures sensitive audio remains within the organization’s premises, reducing risks associated with cloud-based transcription services. The system transcribes meetings in real-time, produces enterprise-grade minutes using existing organizational templates, and identifies speakers, all while disconnected from external networks.
“In a world where trust and privacy are non-negotiable, our solution empowers leadership teams to collaborate, decide, and move faster, without compromising data control,” said Hugo Flayac, CEO at csky.ai.
DuoKey’s Double Key Encryption (DKE) secures transcripts before storage in Microsoft 365, requiring two keys for access—one managed by Microsoft Azure Key Vault and another controlled externally by DuoKey’s key management system. Multi-Party Computation distributes key control across multiple secure locations, ensuring no single entity can compromise the data. “Our encryption solution ensures that confidential transcripts are never exposed to cloud-based servers — including Microsoft,” said Nagib Aouini, CEO at DuoKey.
The solution meets stringent compliance requirements, including GDPR, HIPAA, and CCPA, by keeping data processing on-premises and providing cryptographic controls. It enables legal, healthcare, financial, and intellectual property-focused organizations to maintain secure audit trails and meeting records without exposing sensitive information. This makes it ideal for transcribing board meetings, legal consultations, and strategic planning sessions.
By integrating offline AI transcription with advanced encryption, csky.ai and DuoKey offer a privacy-first solution that enhances productivity without sacrificing security. The technology supports organizations in regulated industries, allowing them to leverage AI transcription while ensuring data sovereignty and compliance. Demonstrated at Vivatech 2025, this innovation sets a new standard for secure enterprise collaboration.
This launch positions csky.ai and DuoKey as leaders in secure AI-driven transcription, empowering organizations to manage confidential discussions with confidence in the Microsoft 365 ecosystem.
