This AI is yours.
Built open and for European sovereignty
Platte is the entry point when you want to bring sovereign AI into your whole organisation. One platform for all your AI use cases.
Chat, analyse files and research the web with sources.
Create Word, Excel, PowerPoint and PDF files right in the chat.
An agent that reads and edits code and runs commands in your project folder.
Connect your tools via MCP and get tasks done right inside them.
Use the same models in your own code through the OpenAI-compatible API.
Invite users, control roles and model access, and review usage across your whole organisation.
Modern AI models on genuinely European infrastructure. Open code, GDPR by design and no US access from the very first prompt.
Powerful AI, but prompts and data are processed at US hyperscalers, with no technically verifiable data-protection guarantees.
Full data control, but only with dedicated hardware, in-house know-how and ongoing maintenance.
Open models now match their US counterparts. That makes true sovereignty possible without compromising on performance.
Register your organisation, connect your tools, invite your team, start using AI — even an organisation-wide rollout of sovereign AI works with Platte as a self service.
We keep track: with Platte you automatically get access to the newest and most capable open AI models the market has to offer.
All services run on European infrastructure managed by European providers. Entirely without US dependencies. Privacy-compliant by design.
Platte offers every benefit of modern SaaS software, without giving up real sovereignty along the way.
Our mission
Open-weights models belong to no US corporation and sit behind no paywall. We in Europe now have the chance to become independent and sovereign in the AI revolution. Let us take it.

Platte is a sovereign AI workspace for organisations: chat, code and agents run in an instance of your own, hosted in Europe. People ask questions, work with files, create documents and group related chats into projects – each with its own instructions, context and memory.
No. The assistant works with more than text: it researches the web, runs code in a sandbox, analyses images and produces finished files such as Word documents and PDFs. Through integrations it uses your tools, and in the desktop app’s code mode it works directly in a folder on your own machine. Your own applications reach Platte through the OpenAI-compatible API.
No. The browser is enough for everyday work: you describe what you need in your own words and the assistant decides which tool to use – every step is visible in the chat. Code mode, API keys and the OpenCode integration are additional routes for developers, not a requirement.
Platte builds on open models such as Mistral, DeepSeek, Qwen and GLM and sources them from European providers that rely exclusively on infrastructure in Europe. The default is “Auto”: it routes you to the fastest model that is capable enough. Admins decide per model whether it can be used in chat or through the API. We add the newest and best open models soon after their release.
Through the Model Context Protocol, MCP for short. Admins enable integrations from the Platte catalogue – Slack, Notion, GitHub or Atlassian, for example – or add their own MCP servers for internal systems. Each person then connects with their own credentials, via OAuth or an API token; the assistant calls the system on their behalf.
Every organisation gets its own instance in a European data centre, with its own database and separate from every other customer. The models are hosted in Europe as well. Chats, files and memory stay in your instance, are not used to train models and can be exported in full as a backup.
Admins assign roles and seats, decide which models and integrations are available, and set a monthly extra-usage budget per person. The usage overview shows consumption by member, model and tool; the storage overview shows sizes and file counts only, never file contents. Sign-in works without a password, using a one-time code sent by email.
Self-service: in the customer portal you set up your instance in a few minutes and try Platte free for seven days, with no payment details. Then you invite your team, one by one or by CSV, and the “Getting Started” checklist walks through the first tasks. For the rollout, the documentation lays out a plan for the first four weeks. We are happy to support you along the way and to accompany the rollout in your organisation.
