Frequently asked questions about PromptLeo
What is PromptLeo?
PromptLeo is a GDPR-compliant AI workspace and prompt engineering platform developed and hosted in Germany. It goes beyond chat interfaces like ChatGPT Teams to let you build custom AI agents trained on your data, create customer-facing chat widgets, build workflows, and connect to business systems. It turns conversations into infrastructure with true workspaces, real collaboration, and complete security.
Is PromptLeo GDPR-compliant?
Yes, PromptLeo was built with GDPR and the European market in mind. It is developed and hosted in Germany with heavy focus on privacy and GDPR compliance. Choosing a GDPR-compliant AI workspace ensures your AI implementation adheres to strict European data protection regulations, especially important when handling sensitive or proprietary information.
Do you mark up AI model usage costs?
No, you bring your own API keys from OpenAI, Anthropic, AWS, and other providers. PromptLeo doesn't markup usage - you pay AI providers directly at their rates.
What document formats does PromptLeo support for knowledge bases?
PromptLeo's AI Workspace supports a wide range of document formats including Word, Excel, PDF, Markdown, and others. This versatility allows you to make all your existing content and data AI-ready without format conversion hassles.
How are workspaces isolated from each other?
Each workspace has completely separate data storage, knowledge bases, and access controls. Users in Workspace A cannot see or access anything in Workspace B unless explicitly granted. This is perfect for agencies managing multiple clients or enterprises with strict data boundaries.
How does PromptLeo prevent AI hallucinations?
PromptLeo's advanced RAG infrastructure tackles hallucinations through multiple technologies including chunking and indexing with embeddings, full-text search (BM25), LLM re-ranking for enhanced accuracy, and query refinement with hybrid search. These features work together to ensure responses are grounded in your actual data.
Is my company data used to train AI models?
Absolutely not. Your company data stays completely private and is never used to train underlying AI models.
Do I need technical skills to use PromptLeo?
No, the core features (chat, workflows, knowledge bases) are designed for business users. Advanced features (API endpoints, system integrations) have technical options but also no-code interfaces, making it accessible to non-technical users.
What support is included with each plan?
All plans include documentation and tutorials. Professional and Enterprise plans include dedicated Customer Success Manager, custom training programs, and implementation assistance. For Enterprise clients, feature development is prioritized based on customer needs.
Can I deploy PromptLeo on-premise?
Yes, for critical use cases PromptLeo offers on-premise deployment options. You control all access with explicit authentication, defined permissions (read-only, specific operations), and all system interactions are logged for audit. You can revoke access instantly.
