Picture your ChatGPT sidebar right now. Fifty threads, three Projects, a dozen pins, and zero chance of finding that one prompt from last Tuesday. A Redditor going by u/Leading-Display-9731 just shipped a fix over in r/PromptEngineering, and the twist is exactly where that fix lives.
I’ll be honest, I’ve lost good prompts in that same flat list more times than I want to admit. ChatGPT’s native Projects feature helps a little, but it only goes one level deep. Drop fifteen conversations into a Project called “Work” and you’re right back to scrolling, just inside a smaller box.
So this creator built a free Chrome extension called Ai Chat Explorer to solve their own version of that mess. The tool doesn’t touch ChatGPT’s core structure at all. It slots nested folders inside your existing Projects, so a top-level Project becomes the trunk of a real folder tree instead of a flat pile.
Here’s what that tree can look like in practice. A Project called “Work” branches into “Marketing,” “Product,” and “Meetings.” Inside “Marketing,” you get “Social Media,” “Website,” and “Analytics.” Inside “Social Media,” you get “Content Ideas” and “Campaign Drafts.” That’s four folder levels deep, all inside one native ChatGPT Project, something the built-in sidebar simply can’t do on its own.
Here’s the part that actually makes this interesting. Most sidebar organizers try to replace ChatGPT’s structure entirely, which usually breaks the moment OpenAI ships a UI update. This one leaves Projects exactly as they are and nests a full file-explorer hierarchy inside them instead. You get unlimited folder depth without losing a single native feature, including Pins and Quick Access for the handful of chats you touch every day.
The build is also open source. The code sits right there on GitHub if you want to see how it hooks into ChatGPT, or fork it for your own tweaks. That’s a rare move for a solo weekend project, and it earns some trust in a category full of sketchy extensions asking for broad permissions.
Want to try the same setup on your own sidebar? Here’s the mini-workflow:
- Install Ai Chat Explorer straight from the Chrome Web Store, just search the exact name.
- Open an existing Project, or create one for a broad category like “Work” or “Clients.”
- Inside that Project, add nested folders for sub-topics, then sub-sub-topics, as many layers as you actually need.
- Pin your five busiest threads so Quick Access surfaces them no matter how deep they’re buried.
- Rename folders to mirror your real workflow, not your first instinct, since you’ll rename them anyway in week two.
Pro tip: name folders like actual file paths, something like “Marketing / Social / Content Ideas.” Then you can scan the whole tree at a glance instead of clicking into every layer to check what’s inside.
Second pro tip: keep Quick Access reserved for chats you touch weekly. Everything else belongs in a folder, or that shortcut list turns into the same cluttered mess you were trying to escape in the first place.
Third pro tip: build your folder tree around the projects you’re actually running, not some abstract system you saw online. The example in the original post split “Work” into Marketing, Product, and Meetings because that’s how the creator’s actual job is structured. Copy the logic, not the exact labels.
One caveat worth knowing before you install anything. This lives entirely in your browser, so folder structures likely won’t follow you across devices unless the creator adds sync later. Worth confirming that in the GitHub repo before you build out a huge tree you’d hate to lose.
Compare that to the usual workaround: typing prefixes like “01,” “02,” or “URGENT” into chat titles and hoping the flat list sorts itself. Actual nested folders are a real structural upgrade, the difference between labeling a messy drawer and building the dresser it should’ve had all along.
This matters more for anyone doing serious prompt engineering than it looks at first glance. Iterate on one prompt across dozens of test runs, and a flat sidebar makes it hard to trace which version led to which output. A folder per experiment, with sub-folders for variants, turns that chaos into something you can actually audit later.
It’s also a good reminder that the biggest wins in this space aren’t always a new model or a clever prompt trick. Sometimes it’s just someone getting annoyed enough at their own sidebar to fix it, then sharing the fix instead of keeping it private.
If your own ChatGPT sidebar has turned into a junk drawer, this is worth five minutes of setup. Go grab Ai Chat Explorer from the Chrome Web Store and drop your existing Projects into a real folder tree. See how much faster you find last week’s prompt. Then swing by the original thread and tell the creator what feature you wish ChatGPT shipped natively. 🗂️
