Private language model
Open-source models you control. Your data never trains anyone else's model.
Open-source models you control. Your data never trains anyone else's model.
Text, images, PDFs, Word files and audio in one engine - ask questions across all of them.
Ready for your stack: APIs and integrations to CRM, ERP and document systems - build in-house or with a partner.
Dedicated European infrastructure means fast answers for every user.
Private AI Infrastructure. Built for modern organisations.
ZCore is Zeldoc's private AI engine, built on specialised components - not one monolithic model. It handles conversation, coding, vision, voice, document processing and web search, all on dedicated EU infrastructure.
Under the hood, ZCore consists of a series of underlying models, each handling specific tasks within the language engine. Together they appear to the user as one seamless, private AI assistant.
Each component is designed for a concrete user-facing capability. ZCore handles text analysis, conversation and multilingual language understanding. ZTask provides coding intelligence, technical reasoning and tool-based actions such as web search. ZTranscribe transcribes meetings, notes and audio into text. ZEmbed enables retrieval-augmented generation (RAG) by embedding uploaded documents for AI-powered search and analysis.
Organisations can use ZCore as the foundation for private, business-secure AI applications: internal AI assistants, knowledge platforms, document intelligence, meeting transcription and business workflows. Data stays fully under control - everything is processed on dedicated European infrastructure without third parties gaining access to sensitive information.
ZCore delivers GDPR compliance, AI Act readiness and Zero Data Retention on local/EU models.
What ZCore does not do
ZCore does not include local models for image generation or video generation. These capabilities require external frontier models accessed through ZRouter, which means data leaves the EU at inference.
What powers ZCore
Each component below handles one concrete capability. Local components run entirely on EU infrastructure - image and video generation require external models.
Text analysis, conversation and multilingual language understanding. Powers chat, summarisation, rewriting and reasoning across languages.
Coding intelligence and technical reasoning for software development workflows, code generation, technical problem-solving and tool-based actions such as web search.
Transcribes meetings, notes and audio into text with high accuracy across multiple languages (ASR).
Embeds uploaded documents for retrieval-augmented generation (RAG), enabling AI-powered search and analysis of your knowledge base.
Not available locally. Requires external frontier models via ZRouter - data leaves the EU at inference and Zero Data Retention cannot be guaranteed.
Quality benchmark
Quality grades for concrete, user-facing capabilities. Grades are on a 1-5 scale with one decimal. Higher is better.

Data sovereignty & GDPR
For each capability, this table shows whether data stays in the EU (data sovereign) and whether the function is GDPR compliant - for ZCore and for external frontier models.
| Capability | ZCore: Data sovereign | ZCore: GDPR | External frontier models |
|---|---|---|---|
| Text analysis & conversation | Yes | Yes | Not sovereign |
| Coding & technical tasks | Yes | Yes | Not sovereign |
| Read PDF documents | Yes | Yes | Not sovereign |
| Read Word documents | Yes | Yes | Not sovereign |
| Read PowerPoint† | Yes | Yes | Not sovereign |
| Read Excel† | Yes | Yes | Not sovereign |
| Image reading & understanding | Yes | Yes | Not sovereign |
| Image generation | No - requires external | Partial | Not sovereign |
| Video generation | No - requires external | Partial | Not sovereign |
| Web search | No - data sent to search engines | Partial | Not sovereign |
| Task execution (agentic) | Yes | Yes | Not sovereign |
| Text to voice (TTS) | Yes | Yes | Not sovereign |
| Voice to text (ASR) | Yes | Yes | Not sovereign |
| Multilingual handling | Yes | Yes | Not sovereign |

Key takeaways
Strong AI performance across text, coding, documents, vision and voice - with 100% EU data sovereignty for all local components and no third-party access to your information.
Image and video generation require external models via ZRouter, so data leaves the EU for those calls. Web search is not data sovereign either - queries are sent to external search engines.
External models may score higher on some benchmarks, but ZCore keeps your data in the EU - for 12 out of 15 capabilities. For the remaining 3, ZRouter provides governed access with policy control through ZControl.
