What is Kasimir?

An overview of Kasimir, the GDPR-compliant multi-LLM AI platform for German mid-market companies, its features and its hosting in Germany.

Kasimir is a GDPR-compliant AI platform for German mid-market companies. Employees chat with leading AI models, analyze documents, transcribe meetings, run multi-step workflows, and collaborate in shared projects — all through a single secure interface, operated in Germany. The guiding idea: sovereign AI without a trade-off between capability and data protection.

The core idea

For a mid-market company, adopting AI today often means facing a dilemma: the most powerful models run on US servers, many "GDPR-compliant" alternatives are just thin wrappers, and most tools are built for engineering teams — not for sales, HR, accounting, or management.

Kasimir closes exactly that gap. By default, every request runs on open-source models (Gemma) self-hosted in a German data center — your inputs are processed on our own servers. When a task needs a frontier model (such as GPT or Claude), it is processed GDPR-compliantly within the EU, contractually safeguarded the same way, and without your inputs being used for model training.

Who Kasimir is for

Kasimir is a platform for every employee, not just technical teams. Typical user groups:

• Sales & customer service — drafting reply emails, preparing quotes, writing customer correspondence

• HR & administration — job postings, internal announcements, document research

• Accounting & controlling — summarizing reports, analyzing spreadsheets, clarifying technical questions

• Project teams — shared workspaces with their own chats, documents, and meetings

• Management — quick research, decision briefs, meeting minutes

What Kasimir can do

Kasimir bundles a broad range of capabilities into one interface. The most important at a glance:

Chat as the starting point

Chat is the heart of the platform. You ask a question, optionally attach files, and switch models when needed. Through the Tools menu you selectively switch on web search, data analysis, image generation or diagrams; company knowledge, connected services and databases are chosen under Knowledge sources. Longer texts don’t appear inline in the chat but as an artifact in the editor on the right, where you can edit them directly.

Agents and workflows

An agent is more than a chat: a persistent persona with its own system prompt, preferred model, dedicated knowledge base, and access to integrations such as Outlook, Jira, or a database. Workflows, by contrast, are multi-step flows that start manually, on a schedule, via a form, a webhook or an integration — ideal for recurring processes that should always deliver the same result at the same quality, without the team having to write prompts.

Data protection and hosting

At Kasimir, data protection isn't a bolted-on feature but architecture. The core commitments:

• Hosted in Germany — your data and the self-hosted models reside in a German data center

• Models in Germany or the EU — the self-hosted models run on our own servers in Germany, the optional cloud models in the EU. A model outside the EU can only be used if your company explicitly allows it. Individual service providers based outside the EU are listed in the privacy policy.

• GDPR-compliant — data processing agreement, data minimization, and the right to erasure are contractually anchored

• No training on your data — training opt-outs are implemented in the contracts with all model providers

• Self-hosted document analysis — no third-country transfer during knowledge processing

Integrations

Agents in Kasimir don't work in isolation but directly inside your existing systems — using your existing access and GDPR-compliantly. Already connected:

• Microsoft 365 — Outlook Mail & Calendar, OneDrive, SharePoint

• Google Workspace — Drive, Calendar, Sheets, Docs, Slides, Tasks

• Jira and Confluence

• Nextcloud and ownCloud

• MSO — read, create and update process data

• Microsoft Teams

• SQL databases (read-only)

In addition, folders from Microsoft 365, Google Drive, Nextcloud or ownCloud can be synced as a knowledge base, so the AI can search their contents.
