Human-Centered AI Technology
YEJIN builds practical, secure, and trustworthy AI solutions powered by AI orchestration and Multi-Brain cross-model validation—helping businesses make better decisions, streamline operations, and turn complex data into actionable insights.
Technology should serve people.
New generative AI models appear constantly, but you can't test which one answers best for every question.
It's hard to trust generative AI answers without supporting evidence and verification.
Enterprises must also weigh security, data integration, and operational reliability.
ZeliAi
ZeliAi connects diverse AI models, data, and specialized agents in a single environment, and provides the most suitable way to use AI for each purpose.
01
Analyzes the context of the web and connected data to find information close to the user's intent.
02
Use diverse AI models together through a single account and interface.
03
Compares and analyzes results from multiple AI models to reduce dependence on a single model and improve the reliability of information.
04
Specialized AI designed for each field's tasks supports everything from information search to task execution.
Multibrain
See for yourself how multiple AI answer the same question at once, and how those results are cross-validated and synthesized into a single, high-confidence answer.

Internal-network AI server, access control, local RAG, lightweight models
Expected Outcomes
Use AI while retaining control over your enterprise's internal data.
Shorter information search time
Search information scattered across many documents and systems with a single query.
Automation of repetitive work
AI handles repetitive tasks such as summarizing documents and drafting content.
Support for comparing results from multiple AI models
Compare and cross-validate answers from multiple AI models for a single question.
Stronger enterprise data security
On-premises and air-gapped deployments keep sensitive data from being exposed externally.
Actual outcomes vary by project scope, deployment environment, and data conditions.
An open architecture with no lock-in to any single model or vendor—supporting you from validation through operations.
We select and connect diverse commercial and open-source AI models according to the customer's purpose and environment.
Through RAG and Multi-Brain cross-model validation, we review the evidence and consistency of results together.
Based on our experience operating our own AI platform, we design AI solutions suited to enterprise environments.
We build for cloud, hybrid, on-premises, and other setups to meet the customer's security needs.
We provide strategy planning, UX, development, infrastructure, and operational enhancement as one integrated system.

ZeliAi does not rely on a single AI model. It has a Multi-Brain structure that compares and cross-validates answers from multiple AI models. Compared with a single-model service, you can confirm the evidence and reliability of results together.
Yes. Through RAG-based knowledge retrieval, you can integrate internal documents and data. The scope and method of integration are designed through consultation according to the data format and security policy.
Yes. With On-Premises and lightweight model (sLM) deployment, AI can be adopted even in fully air-gapped environments.
We build in stages depending on the project scope and the level of data integration. We provide an exact timeline after a preliminary assessment.
Yes. We support API integration with existing business systems such as ERP, CRM, and groupware, and we confirm feasibility in advance according to the system environment.
Costs vary by project scope, level of data integration, and deployment method (cloud or on-premises). After identifying requirements through consultation, we provide a quote.
Yes. You can first confirm the impact with a small-scale PoC (proof of concept) and then expand into the full project.
Yes. We support operational monitoring and maintenance after deployment. The scope of support may vary depending on the contract terms.
ZeliAi is free to use right now, and for enterprise and public-sector adoption, our consultants support you from assessment through deployment and operations.
