1.Compare 10–20 Quotations at Once

Before: Open each file individually, review every line, and manually enter the information into Excel.
Now: Upload all the files to Codex and ask it to:

“Compare the differences in pricing, delivery timelines, warranties, and highlight any points that should be clarified with the vendors.”

Codex can also organize the results into a ready-to-use comparison table.

2.Read a 300-Page Document and Answer Questions About It

Before: Search through the document one page at a time.
Now: Ask questions directly, such as:

• Which page contains the SLA?
• Are there any backup requirements?
• How long is the warranty period?

It is like having someone read the entire document in advance and remain ready to answer your questions.

3.Detect Anomalies Across Tens of Thousands of Excel Rows

Before: Use filters, sorting, and pivot tables.
Now: Ask Codex to identify:

• Duplicate records
• Unusual pricing
• Suspicious figures
• Trends that require further investigation

4.Rename Every File in a Folder at Once

Before: Click Rename on every file individually.
Now: Ask Codex to “Rename all files using the YYYY-MM-DD_ProjectName format,” and the task can be completed within seconds.

5.Create Checklists from Long Documents

Given a 100-page requirements document, Codex can summarize it into:

• Project acceptance checklists
• Audit checklists
• Pre-delivery checklists that are ready to use immediately

6.Identify the Most Common Customer Complaints from Hundreds of Feedback Entries

Instead of reading every entry individually, Codex can categorize the feedback and identify:

• What customers are complaining about
• Which issues occur most frequently
• Which issues have the greatest impact on the business

7.Compare Two Document Versions in Detail

For example:

• Old and revised versions of a Terms of Reference document
• A contract before and after revision

Codex can immediately summarize what was added, what was removed, and which changes may introduce or affect risk.

8.Turn Disorganized Information into a Clear SOP

Many people keep their work processes in their heads or scattered across emails and LINE conversations. Codex can consolidate this information and quickly organize it into a clear, easy-to-follow standard operating procedure.

9.Create a Meeting Agenda from Documents You Have Not Yet Read

Before meeting with a customer, simply provide the relevant documents to Codex and ask, “Create an agenda covering the key topics that should be discussed during the meeting.” The result is a better-prepared team with significantly more time to focus on important discussion points.

10.Discover the Questions You Did Not Know You Should Ask

This capability is particularly impressive. Instead of asking:

“What information is contained in this document?” try asking, “If you were an auditor, project manager, or customer, what concerns would you have after reviewing these documents?” Codex can often identify issues that may have been overlooked, helping teams prevent problems before they occur.
