The AI OS
that runs
your company.
From HR, attendance, and payroll to mail, chat, projects, content creation, and video meetings — every part of your business runs on a single GREND AI Operating System (AI OS). And AI works alongside you in all of it.
From education to the enterprise floor, teams work on GREND as their AI Operating System.
More apps, more broken workflows.
Messaging, mail, approvals, projects, documents… when tools run in isolation, context falls apart. GREND isn't just another app — it's the AI Operating System (AI OS) that holds all of them.
One Operating System
One GREND OS instead of a dozen SaaS tools. Accounts, data, and work on a single foundation.
AI Built In
Not a bolt-on tool, but intelligence woven into every app at the OS level.
Ready the Moment You Turn It On
From HR to content creation, the core apps come pre-installed. Start working the moment you onboard.
Not a metaphor — it actually works like an AI OS.
Open GREND and a familiar desktop appears. Launch apps from the launcher, find any feature in one search, and the screen locks when you step away. A true AI Operating System.
Desktop
Arrange your favorite apps, widgets, and wallpaper your way.
App Launcher & Unified Search
Find and launch any feature in one search (Korean & English).
Notification Center
Mail, chat, and approval alerts in one place — tap to jump to the exact spot.
Screen Lock & Sessions
Away-from-desk protection and multi-device session management.
Everything your work needs is already inside.
Collaboration
Messaging, mail, calendar, and files — all in one operating system, no switching.
- Chat — real-time messaging, thread replies, mentions, up to 10GB file transfer, bookmarks & pinned messages
- Webmail — in-house mail on our own mail server, rich editor, project folders & shared mailboxes
- Calendar — team schedules & attendees, auto leave display, AI bot 9am briefing & due-soon reminders
- Drive — large-file storage & sharing, folders & permissions, external share links
- Notes — block-based docs, tables (cell merge), autosave
- Video conferencing — screen share, real-time captions (STT), recording, live translation
Not scattered data,
but a single ontology.
Because every workflow runs on one data platform, AI connects people, organizations, projects, documents, and schedules into a single knowledge graph (ontology) to understand them. It's intelligence that governs the whole company — something scattered SaaS tools can never reach.
One Data Platform
All your work data in one place. No duplicate entry, no broken silos.
Knowledge Graph (Ontology)
A map of your company where people, projects, documents, and schedules connect by meaning.
Semantic Search
Find answers across the whole company by context, not just keywords.
Governed by AI
AI puts connected data to work through summarization, reasoning, and automation.
Still weighing up AX?
You need to go beyond DX, which merely ‘adopts’ AI. GREND's AX means AI takes the lead in executing work, while people verify and decide.
Adopt AI as a ‘Tool’
People still do the work. AI stays a sidekick that lends a hand.
AI Executes in the ‘Lead’
AI carries out the work directly, while people verify the results and decide. Speed from AI, accountability from people.
AI Executes
AI takes the lead on repetitive, routine work.
Presents with Evidence
Shows results transparently, with sources and reasoning.
People Verify & Approve
People review and decide. Final accountability stays with people.
All of these capabilities, in one GREND.
From groupware to HR, projects, content creation, and AI — replace dozens of tools with the price of one GREND AI Operating System.
