AI Tip: Use Codex Desktop to Connect Your Files, ChatGPT, and the Web

OpenAI Codex just landed on Mac and PC, and travel advisors should pay attention. It delivers a technical assistant that can actually leverage your computer files to do real work.

Complexity Level:  ✈️✈️✈️  (a real sit-down session; some configuration)

Similar to Claude for Desktop, OpenAI recently released Codex as a desktop app for Mac and Windows. While it may have been built for software developers, don't let the name fool you. Codex can work directly with files and folders on your computer. You point it at a folder, and it reads, searches, and works across everything inside without uploading anything or copy-pasting into a chat window.

It can also create and edit files on your computer, and browse the web, and brings all the power of ChatGPT, and is part of your existing ChatGPT subscription, and on, and on. 

This opens a world of possibilities for valuable everyday work:

1. Work with your actual business files. Point Codex at a folder of supplier or client documents. Ask it to pull every cancellation deadline into one list, compare group rates across three suppliers, or find every mention of a specific client across your files. You skip the upload-one-file-at-a-time step entirely.

2. Leverage the web and LLMs to create new things. Want to know the best hotel property for a client in a destination you've never visited based on your client call notes? Maybe you want to compare three cruise itineraries and build a sales pitch based on training PDF you have stored on your computer? No problem. These are the kinds of things Codex handles easily. 

3. Organized project threads. Each task gets its own thread, so "compare Sandals vs. Secrets PDF brochures" stays separate from "draft a group travel proposal." You build up useful context in each thread over time instead of starting from scratch every conversation.

Here's a real example

I have a client notes Word doc in a folder on my computer. It's just fragments of past conversations about previous trips. The client likes Belmond hotels and they want a recommendation for Belmond in Italy. I've only ever stayed at one Belmond property, and that was in Anguilla. So in Codex, I asked:

"Look through this client folder for their preferences and past trips. Then check the current Belmond website for availability and new properties. Create a comparison of three options and destinations that match what they liked last time." 

That's it. I specified the folder location in Codex, but I didn't give it anything else. In my prompt I didn't tell it Italy or even Europe. I just told it about the Belmond brand and referenced the client folder. I didn't even tell it which file the notes were in.

Here's what Codex came up with:

I found the Henderson notes in [client notes-Hendersons.docx]. Their winning pattern last time was: food-first, local texture, not all-inclusive, not a big-brand/conference feel, some movement, and enough slow time that the stay itself feels memorable. They loved Palermo street food, the Catania cooking class, and especially the agriturismo near Ragusa.

I checked Belmond’s current site and booking engine using a representative window of June 28-July 2, 2026, 2 adults because the notes mention late June/early July. Exact family pricing will need a second pass once we know whether it is 2 or 4 travelers and room setup.

New/current Belmond notes: Belmond’s homepage is currently highlighting Villa San Michele, Now Open, plus the new Britannic Explorer train and Marguerite boat; Villa San Michele has new accommodation, a new Antesi dining concept, and a Guerlain spa. It is worth mentioning as a Florence add-on, but I would not lead with it because it risks feeling too city/classic versus what they loved in Sicily.

Recommendation: Lead with Castello di Casole + 1-2 nights Florence/Villa San Michele if they want Italy. Present La Residencia as the best non-Italy family-active alternative and Romazzino as the splashier “new Belmond / Sardinia” option.

Sources: Belmond homepage for new/current highlights, Castello di Casole, La Residencia, Romazzino, plus live Belmond booking engine checks.

It also generated a more detailed Word doc.

Is this perfect? Can you send straight to your client? No, probably not. But does it save you some time and point you in the right direction to match your client with exactly what they're looking for? You bet it does.

A few honest notes about Codex

Codex Desktop works with a free ChatGPT account (limited usage) or ChatGPT Plus ($20/month) for more capacity or ChatGPT Pro, of course. The initial setup takes a few minutes. The app is new and still rough around some edges. Codex can go much, much deeper if you want to feel adventurous, but even if you only go this deep, the uses are nearly endless.

Try this today: download Codex Desktop from OpenAI, install it, and point it at one folder (supplier docs are a good start). Ask it: "List every cancellation policy and deadline you find in these documents." 

– Keep building with AI,
