Co-Brain is a GDPR-compliant AI operating system for bid, sales, legal and compliance teams. It provides secure, auditable AI agent workflows that work from your company knowledge and to your standards - from the tender to the internal knowledge request.

Co-Brain is built for bid, sales, legal and compliance teams, particularly in regulated industries that require security, quality and compliance.

Will my data be used to train AI models?

No. Your data does not train any models - neither Co-Brain's nor those of providers such as OpenAI, Anthropic or Mistral.

How does Co-Brain protect customer data?

Co-Brain uses TLS encryption for all network connections, AES-256-GCM encryption at rest via AWS KMS, and encrypted redundant backups. It is GDPR-compliant, hosted in the EU, and available as private cloud, hybrid or on-premise deployment. Existing permissions are always preserved so each user only sees what they are allowed to.

Which AI models does Co-Brain use?

Co-Brain is model-agnostic. It can use GPT-5.1, Claude, Gemini, Mistral or your own models, selecting the best model for each task with no vendor lock-in.

Where is Co-Brain's data hosted?

Data is hosted in the EU. Co-Brain can be deployed as private cloud, hybrid or on-premise, and operates under German law.

What makes Co-Brain different from generic AI chatbots?

Co-Brain delivers auditable AI, not generative AI. It orchestrates specialized agent workflows with team collaboration and approval instead of a simple chat. Every answer includes a source citation and confidence score - no black box.
