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 (Mistral, Llama, Gemma, DeepSeek) self-hosted in a German data center — your data never leaves the infrastructure. When a task needs a frontier model (GPT, Claude, Gemini, Perplexity), it is processed GDPR-compliantly within the EU region, 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 Werkzeuge (Tools) menu you selectively enable capabilities like web search, data analysis, or the database agent. Longer texts don't appear inline in the chat but in the sidebar 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 form-based and multi-step — 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 — data and self-hosted models run exclusively in a German data center

• No third-country transfer for self-hosted models; frontier models are also processed within the EU region

• 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 embeddings (BAAI/bge-m3) for 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

• Microsoft Teams

• SQL databases (read-only)

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

Availability

Kasimir is currently in a closed beta. You request access via Beta beantragen (Apply for beta) on the home page. Pilot contracts are agreed individually; detailed pricing will appear with the public launch.
