What is ZeliDesk
As new AI services grow rapidly, users have to find a website for each service, open multiple windows, and learn different interfaces. During work, they repeatedly move between file search, PDF processing, image conversion, network checks, document writing, data analysis, and development tools. ZeliDesk consolidates this fragmented work environment into a single Windows application.
Reduces the hassle of moving between a separate site and screen for each AI service.
Quickly runs file, document, image, security, and development utilities in one app.
Cuts the steps of copying and reorganizing AI answers, and produces output directly in Excel and Word.
Guides you to AI model formats and runtimes suited to your PC specs, and provides tools to manage local models.

Understands the structure of the input source data.
Applies formulas to match the requested conditions.
Inserts a chart that visualizes the calculated results.
Automatically applies formatting that improves readability.
Organizes the finished results into a report format.
Example — “Draft a parent notice, add a title and signature line, and save it as a PDF.”
Drafts the document on the requested topic.
Composes readable tables and paragraph styles.
Adds a header and signature line that fit the document format.
Rechecks the written content.
Saves the finished document as a PDF file.
Expands beyond AI that generates answers to AI that completes real documents and data.

It is a Windows 11 AI desktop hub that integrates major AI services, AI Office automation, 73 practical utilities, and a Local AI runtime.
ZeliDesk is provided as Free & Open Source software. However, the external AI services you use inside ZeliDesk may be subject to each provider's account and pricing policy.
No. ZeliDesk helps you switch conveniently between multiple AI services in one app. Login, subscription, and usage limits for each AI service follow that provider's policy.
It currently supports Windows 11, on both x64 and ARM64 architectures.
The Excel and Word automation features work by controlling the actual Microsoft Office programs, so an environment with those Office applications installed may be required.
In Excel it supports data entry, formatting, formulas, charts, conditional formatting, and multi-sheet work; in Word it supports paragraphs, tables, styles, headers, find and replace, and PDF export.
Through zLM, yLM, TensorRT-LLM, and the AI model format guide, it supports Local AI model management and runtime configuration.
File, development, and system utilities and Local AI features can be used offline depending on the configuration. External AI web services require an internet connection.
It is built to support use in educational institutions and institution-level adoption, and the scope of rollout, training, and operations can be discussed separately with YEJIN.
Depending on an enterprise's or institution's scale, security policy, deployment method, and Local AI and education needs, a separate adoption discussion can be arranged.
Experience 12 AI services, 73 built-in utilities, Excel and Word AI automation, and Local AI in one Windows application. ZeliDesk is not simply a program that gathers many AI together — it is an AI desktop platform that connects AI with documents, data, files, and development tools to actually run the user's work.
The external AI services connected inside ZeliDesk may be subject to each provider's account, terms of use, pricing, and regional policies. Features and the scope of support may change with product updates.
