# inline AI

> inline AI is a self-driving AI OS for enterprise, built by Elements Corp. (Seoul). Scattered company data (ERP, Excel, mail, bank, portals) comes together on one data platform; AI agents register orders, post journals, and file approvals on top of it; staff build custom apps and document workflows by describing them. Elements Corp. also ships a free personal desktop AI agent for Windows that edits Excel, HWP, Word, and PowerPoint files locally (Korean site only).

## What inline AI Is (Enterprise)

Four platform products run on one company data platform:

- **inline Data Platform**: every customer, order, item, work order, journal, and employee from ERP, Excel, mail, and bank feeds, kept as one ontology with the source and edit rights on every field.
- **AI Agent**: asks why something happened on the connected data, finds the cause, and acts (sends the email, text, or purchase order, registers the order, posts the journal).
- **App Builder**: dashboards, admin screens, process automation, and per-customer forms built by staff in plain language, on the same data and permissions.
- **Document Workflow**: certificates of analysis, quotes, test reports, and contract reviews written from company data in the company's own Word, Excel, PowerPoint, and HWP templates, triggered when a file lands, a mail arrives, or data changes.

Apps built on the platform: AI ERP, AI Groupware, AI SCM, AI PMS, plus 48 gallery apps for sales, purchasing, production, logistics, finance, tax, HR, approvals, customer service, reservations, associations, and reporting.

Agents act with the permissions of the person who called them; every action is logged with the previous value; data is stored encrypted in a domestic region and never used to train models.

## Personal Product (Korean site)

The personal desktop agent is a standalone Windows application with its own AI engine. It opens and edits Microsoft Excel, Word, and Hancom HWP documents on the user's computer and builds new PowerPoint decks from local source files. Nothing is uploaded for storage. Unlike ChatGPT or Claude, no copy-paste; unlike Copilot, it works across multiple files at once.

## Feature: Excel AI

inline AI controls Microsoft Excel end to end. It reads your actual workbook, writes values and formulas, applies formatting, and manages sheets, rows, and columns.

### Excel Control

- Reads your workbook end to end: understands sheet structure, formulas, formatting, merged cells, and errors all at once.
- Writes values, formulas, and formatting: enters data, applies formulas, sets number formats, and handles copy-paste with full fidelity.
- Manages sheets, rows, and columns: inserts, deletes, renames, hides sheets, and adjusts row heights and column widths.

### Data Integration

- Works across PDFs, Word, PowerPoint, CSV, and images: extracts source material, then edits or creates Word documents and builds new PowerPoint deliverables in the same workflow.
- Cross-references multiple open files: compares and matches data across several Excel files open at the same time.
- Power Query without Power Query: handles multi-source imports, transformations, and consolidation that previously required Power Query setup.

### Data Cleansing

- Detects and fixes formula errors: spots #DIV/0!, #REF!, text-stored-as-numbers, and other issues, then suggests or applies fixes.
- Standardizes formats across columns: unifies dates, currencies, text casing, and phone numbers in a single pass.
- Removes duplicates and fills gaps: deletes duplicate rows, flags blank cells, and identifies outliers automatically.

### Data Visualization

- Creates charts from a single prompt: line, bar, pie, scatter, area, and 3D charts, all generated from a natural-language description.
- Builds pivot tables and slicers: sets up row/column/value fields, calculated fields, and visual slicer filters.
- Applies conditional formatting and table styles: color scales, data bars, icon sets, and preset table styles, applied in one step.

## Feature: Local AI Agent

inline AI is a local AI agent that lives on your desktop. It plans, searches, reads, and executes across your local files, folders, and the web, all without uploading anything.

### Multi-file Workflow

- Scans folders to find relevant files automatically.
- Opens and reads multiple files at once.
- Merges content into a single workbook.

### Local File System

- Works across Excel, HWP, Word, PowerPoint, PDF, CSV, images, and more, including editing Excel/HWP/Word documents and creating new PowerPoint decks.
- Finds and reads hundreds of files at once: sub-agents scan your folders in parallel.
- Edits files on your behalf: creates, updates, moves, and renames files and folders directly.

### Agentic Web Research

- Searches the web across hundreds of sources.
- Builds a structured research report.
- Embeds citations directly in your Excel workbook.

### Safety and Control

- Every edit requires your pre-approval before execution.
- You explicitly grant folder access boundaries; inline AI cannot access folders you have not approved.
- No cloud storage, no middleman; all history and logs stay on your computer.

## Supported File Formats
