Introduction

Hello, I’m Mia Sato, AI Researcher at GDX.

In this article, I’d like to introduce Record & Replay, a new feature added to OpenAI Codex.

When I first saw this feature, I felt that it could make many small but annoying parts of daily work much easier.

In short, Record & Replay lets you show Codex a workflow once on your Mac, and Codex turns that workflow into a reusable Skill.

Instead of trying to explain a long procedure in writing, you can simply show the work once. That is what makes this feature so interesting.

In many workplaces, there are tasks that are not difficult in themselves, but take surprisingly long to explain to someone else.

Each step may be small.
But when people ask about the same process again and again, it becomes a quiet burden.
And when each person checks things in a slightly different order, missed steps and rework can easily happen.

That is why I think the idea behind Record & Replay, showing a task once and reusing it later, fits real workplace needs very well.

In this article, I will walk through the main features of Codex Record & Replay, where it could be useful in daily operations, and what I noticed after trying it myself.

Main features of Codex Record & Replay

What I liked most about Record & Replay is that you do not have to explain everything perfectly first. You can start by showing the workflow.

When using AI, one of the surprisingly difficult parts is writing instructions.
You may know what you want to do, but putting it into words can become long and complicated.
This is especially true for workplace tasks, where a lot of tacit know-how is involved, such as small checks people do almost unconsciously.

Record & Replay seems to make this part much easier.

1. You can show your usual workflow as it is

First, with Record, the user performs the task as usual.

For example, you open an internal system.
Select the target period.
Export a report.
Save the file.

The idea is to show Codex this actual flow of work.

The important point is that you do not need to prepare a polished procedure manual in advance. By showing the actual operation, you can help Codex understand how the work is done.

2. Codex organizes the workflow into a reusable Skill

Next, Codex uses what it observed to organize the workflow into a reusable Skill.

What is the purpose of the task?
What information should be provided next time?
In what order should the steps be performed?
What should be checked at the end?

These elements are organized into a structure that can be reused. So rather than just a screen recording, it feels closer to a practical procedure note for future work.

This is where it feels different from an ordinary screen recording.

3. Next time, you only need to provide what has changed

With Replay, when you need to perform a similar task on another day, you can use that Skill in a new Codex thread.

Instead of repeating the entire process from scratch, you only provide the parts that have changed this time.

For example, last time the report was for May.
This time it is for June.
The workflow is the same, and only the period or file name changes.

This kind of task seems to be a strong fit for Record & Replay.

What I tried: Exporting CrowdLog work-hour data, converting it to PDF, and saving it

I also tried Record & Replay myself using work-hour data from CrowdLog.

CrowdLog is a tool we use at GDX to record and review project work hours. It helps us check who spent how much time on which project afterward.

This time, I tested a workflow where I exported work-hour data from CrowdLog, converted it into a PDF, and archived it on my desktop.

Normally, this involves opening CrowdLog, selecting the target period, exporting the data, checking the file, converting it to PDF, and deciding where to save it. None of the steps are difficult on their own.

The screen for exporting work-hour data from CrowdLog. Selecting the target period and output items was also part of the workflow shown to Record & Replay.

But in practice, there are many small actions involved.

When I showed this workflow once with Record & Replay, I could see how the steps, such as which screen to use, what to select, how to handle the file, and where to save it, could be preserved as a reusable procedure.

That said, the workflow did not become perfectly reproducible from the first Skill that was created.

In my case, I tried Replay several times and gave Codex feedback, such as which items should be checked before exporting, where the PDF should be saved, and which parts of the screen should be confirmed.

After I shared the issues I noticed during Replay, Codex updated the workflow and regenerated the PDF and Excel files.

After that, I spent about another hour testing Replay and making small adjustments.

What I felt through this process is that Record & Replay is not something you record once and finish. It works better when you refine the workflow through several rounds of testing.

For that reason, it seems better to start with a short workflow rather than recording a long business process all at once. For example, you might begin with just exporting the data, then extend it to PDF conversion, and finally add the step of saving it to a specific location.

First confirm that a short workflow can be reproduced correctly, then gradually expand the scope. After trying it myself, I felt that this approach is more likely to produce stable results.

What types of work is Codex Record & Replay suited for?

After testing it, I felt that Record & Replay is not a tool for automating everything. It is closer to a tool that helps reduce the burden of repeated procedures.

It seems especially useful for tasks that follow almost the same flow each time.

Tasks that are a good fit

  • Exporting and saving regular reports
    Tasks where you export reports from the same screen every week or month, changing only the period or conditions.
  • Organizing and storing files
    Tasks such as renaming downloaded files and saving them to a designated folder.
  • Preparing internal applications or forms
    Tasks such as expense applications, approval requests, and internal forms where similar fields are filled in repeatedly.

Tasks that require caution

On the other hand, I do not think it is well suited for tasks where the judgment criteria change every time.

Examples include complaint handling, refund decisions, price negotiations, and hiring decisions.

Tasks that display a lot of customer information, sales data, cost data, contract details, or personal information also need to be handled carefully.

If you try Record & Replay for the first time, it is probably best to start with a task that is short, repetitive, and low-risk even if something goes wrong.

Saving last month’s report, checking items before publication, or preparing internal form inputs may be good starting points. These kinds of tasks make it easier to understand the value of Record & Replay.

What to be careful about before using it

After trying Record & Replay, I felt that deciding what to record is just as important as the convenience of the feature itself.

Avoid screens that show personal or confidential information

With Record & Replay, you show Codex the flow of your work.
That means you need to be careful not to expose personal or confidential information while recording.

Screens that show customer names, email addresses, sales figures, cost data, contract information, or internal documents should be avoided as much as possible.

If needed, use dummy data.
Reduce the number of visible fields.
Close unnecessary screens before recording.

These are points worth preparing before you begin.

Do not have Codex enter login information

If the service requires login, it is safer to log in yourself first.

For example, when using CrowdLog, internal systems, a CMS, or other admin tools, you should avoid giving Codex your account ID or password and asking it to enter them.

A safer way is to open the browser yourself and log in to the target service first.
Then you can tell Codex, “Please use the page that is already open in the browser.”

This allows Codex to work with the screen without directly receiving your login information.

In business systems, login information is not the only concern. Two-factor authentication and internal access permissions may also be involved. Rather than asking Codex to handle authentication from the start, it is safer to show it only a limited task after a person has logged in.

Recording is currently Mac-based, but reusable workflows may be shared with Windows users

At the moment, the recording feature of Record & Replay is presented as a Mac-based workflow.

On the other hand, the Codex app itself is also available on Windows, and Skills are supported in the Windows version as well.

This means one possible approach is for a Mac user to record a workflow first and organize it into a reusable procedure. Then, Windows users could use the same procedure afterward.

I think this is an important point for real-world use.

Many people in corporate and back-office roles use Windows devices. If workflows can be recorded on Mac and then shared with Windows users, it could make the feature easier to adopt across a whole team.

Conclusion

If Codex Record & Replay becomes more widely used, the way teams approach workflow automation may gradually change.

The biggest point is that tacit operational know-how, which often stays in one person’s head, can become easier for the whole team to reuse.

The checking order that only experienced members knew, and the small steps people handled almost unconsciously, may gradually become easier to share.

That could also reduce the burden of handovers and training.

By reducing the time spent on repeated tasks, people can spend more time on judgment and improvement.

Not just creating reports, but deciding what to change based on the numbers.
Not just saving files, but thinking about how to use the information.
Not just getting caught up in checking tasks, but designing operations that make mistakes less likely.

As AI begins to support the small procedures behind daily work, the role of people in the workplace may also change little by little.

Rather than simply completing tasks, people will increasingly design, check, and improve the parts of work they hand over to AI.

This kind of approach may become more important in the next stage of workflow automation.

Start small, make small improvements, and gradually turn the workflow into a team standard.

I think this steady process is one of the most realistic ways to make AI use take root in the workplace.
