# Welcome to DeepMask

> DeepMask unifies 25+ leading AI models in one GDPR-compliant EU workspace. No vendor lock-in, no model training on your data, built for enterprise teams.

DeepMask is a unified AI workspace that gives your team access to more than 25 of the world's leading AI models — including GPT, Claude, Gemini, Mistral, DeepSeek, Kimi, Qwen, MiniMax, GLM, and Gemma — from a single interface at [chat.deepmask.io](https://chat.deepmask.io). This page explains what DeepMask is, what it can do, and who it is built for, so you can quickly understand whether it fits your organization's needs.

## What DeepMask is

DeepMask is a sovereign European AI workspace SaaS. It runs on StackIT — the German cloud platform operated by the Schwarz Group — alongside EU-region infrastructure from other hosting partners, ensuring your data never leaves European jurisdiction.

## Key features

### 25+ AI models, one interface

DeepMask unifies top AI models so you can switch, compare, and choose the best tool mid-conversation — without juggling logins or separate subscriptions. Available models include GPT-4o, GPT-5.2, Claude Opus and Sonnet, Gemini 2.0 Flash and 2.5 Flash, Mistral, DeepSeek, Grok, Kimi K2, Qwen, Gemma, and more. EU-hosted variants of select models (Qwen3 via StackIT, Gemma 3 27B via StackIT, GPT-OSS 120B via StackIT) are available for stricter data residency requirements.

### Projects

Create persistent, context-rich workspaces that remember your instructions, files, and preferences across sessions. Upload documents, set custom instructions, and share projects with teammates for collaborative work.

### MCP connectors

Connect DeepMask to the tools your team already uses — Google Drive, Gmail, Google Calendar, SharePoint, Salesforce, and more — through the open MCP (Model Context Protocol) framework.

### AI-powered web search

DeepMask integrates Perplexity-powered web search directly into your AI conversations, delivering real-time, cited answers grounded in the latest information without leaving the chat.

### Response style controls

Choose from five response styles — Normal, Concise, Explanatory, Learning, or Formal — and DeepMask adapts its output instantly to match the task.

### Data visualization

Upload spreadsheets, CSVs, or documents and let AI handle the analysis. Get instant charts, insights, and polished reports — no coding required.

### Enterprise team management

Manage teams, projects, and usage across your organization. Track total token consumption and model distribution to understand ROI and enforce team-level policies.

## Who DeepMask is for

DeepMask is designed for organizations that need AI across multiple departments without building or maintaining their own infrastructure.
