The custom AI assistant that respects your data and your budget.
Stop paying per-seat taxes for corporate AI. Deploy a private Open WebUI instance that connects to your documents, follows your rules, and stays entirely on your infrastructure.
Why teams choose a custom AI assistant over SaaS
Enterprise AI shouldn't mean surrendering your data or your bank account. Open WebUI on Opsily gives you the power of GPT-4 or local models without the vendor lock-in.
No per-seat licensing
SaaS providers charge more as your team grows. We don't. One server price covers your entire company. Add 10 users or 100 users for the same flat monthly fee. Scale your AI assistant without scaling your budget.
True data sovereignty
Public AI tools use your prompts to train their models. Open WebUI on Opsily keeps your data in German data centers. Your proprietary code, internal docs, and client secrets stay yours. Fully GDPR compliant by design.
Deep RAG integration
Turn your PDFs, Notion pages, and Confluence docs into an instant knowledge base. Your custom AI assistant answers questions based on your specific data. No more searching through folders: just ask the assistant.

Why a custom AI assistant beats generic chatbots
Most companies start with a generic ChatGPT subscription. Then they realize the risks. Employees paste sensitive code. They upload customer lists. This data often leaves your control immediately.
Retrieval-Augmented Generation (RAG)
A custom AI assistant powered by Open WebUI uses RAG to bridge the gap between world-class models and your private data. Instead of sending your entire database to the AI, RAG finds the relevant snippets of your documents and provides them as context. This makes the assistant more accurate and less prone to 'hallucinations'.
Multi-Model Orchestration
Don't get locked into one provider. With Open WebUI, you can use GPT-4o for complex reasoning, Claude for long-form writing, or Llama 3 for private, local tasks. You can switch models in seconds without changing your user interface or retraining your staff.
Enterprise Controls
Unlike consumer AI tools, a managed Open WebUI instance gives you admin oversight. You see who is using the system, manage API costs, and set global instructions for how the AI should represent your brand. It is the professional way to deploy AI across 10 to 100 people.

Questions about custom AI assistants
A custom AI assistant is a private version of a tool like ChatGPT that is tailored to your business needs. Unlike public tools, it can be connected to your specific company documents, brand guidelines, and internal databases using RAG technology. This allows the AI to provide answers based on your actual data rather than general internet knowledge. When hosted on Opsily, this assistant lives on your own private server, ensuring total data privacy.
