Nextcloud, the Germany-based open-source collaboration platform, has officially released Hub 8, marking a significant milestone in the evolution of self-hosted productivity software. This release focuses heavily on AI integration while maintaining Nextcloud's core commitment to privacy and data sovereignty.
Unlike cloud-based AI assistants that send your data to external servers, Nextcloud's AI features process everything locally on your infrastructure. This makes Hub 8 particularly attractive for businesses and organizations that handle sensitive data but still want to leverage AI productivity tools.
Key Features in Nextcloud Hub 8
Local AI Assistant
The headline feature of Hub 8 is the enhanced Nextcloud Assistant, which now includes:
- Text Generation: Create drafts, summaries, and content directly within Nextcloud using locally-running language models
- Smart Summarization: Automatically summarize long documents, meeting notes, and email threads
- Translation: Translate text between languages without sending data to external translation services
- Image Generation: Create images from text prompts using local Stable Diffusion models
- Context-Aware Responses: The AI can access your files to provide relevant, personalized responses
All AI processing happens on your own servers. No data is sent to OpenAI, Google, or any other external AI provider. Your files, prompts, and generated content stay entirely under your control.
Enhanced Collaboration Tools
Hub 8 brings significant improvements to team collaboration:
- Real-time Document Collaboration: Improved Collabora Online and OnlyOffice integration with better synchronization and reduced conflicts
- Nextcloud Office Updates: New formatting options, improved table handling, and better Microsoft Office compatibility
- Talk Improvements: Enhanced video conferencing with better screen sharing, virtual backgrounds, and breakout rooms
- Whiteboard: Integrated collaborative whiteboard for visual brainstorming and planning
Performance Improvements
Nextcloud has invested heavily in performance optimization for Hub 8:
- 50% Faster Sync: The desktop client now syncs files significantly faster, especially for large numbers of small files
- Reduced Memory Usage: Server-side optimizations reduce RAM requirements by up to 30%
- Better Caching: Improved caching mechanisms speed up repeated file access
- Database Optimization: Queries are now more efficient, reducing load on database servers
AI Model Options
Nextcloud Hub 8 supports multiple AI backends to suit different hardware capabilities and use cases:
| AI Backend | Hardware Needed | Best For |
|---|---|---|

| Llama 2 (13B) | 16GB+ GPU or 32GB RAM | Better quality responses, medium teams |
| Llama 2 (70B) | 48GB+ GPU | Enterprise, highest quality |
| Mistral 7B | 8GB+ GPU or 16GB RAM | Fast responses, efficient |

| Whisper | 4GB+ GPU or CPU | Speech-to-text transcription |
For organizations without powerful GPU hardware, Nextcloud also offers optional connections to ethical AI providers that respect privacy, though local processing remains the recommended option.
