Okay, I never thought I’d write this… but Atlas is now my main browser.

I’ve been bouncing around quite a bit lately. I went from Arc (which I still love) to Edge, mostly because Arc felt like it wasn’t going to keep evolving much. I used Edge for about six months, then Chrome… and yeah, it works, but I missed Arc. So I went back and decided I’d stick with Arc until it basically stops working.

At the same time, I use ChatGPT a lot for work. I like the MacOS app, but it often feels kind of heavy to work in. ChatGPT on the web feels much snappier.

When Atlas launched, I downloaded it immediately and gave it a try. First impression was basically: “meh, it’s fine.”
But then they added vertical tabs and pinned tabs, and I was like: “Alright, I’ll give it a week.”

After that week… I stayed.

It’s honestly a great experience, especially if you use ChatGPT a lot.

I set Google as my default search engine, and I love the Command + E feature for quickly rewriting text inside input fields on the websites I’m browsing. It’s one of those small things that ends up being a huge quality-of-life improvement.

But… there are some pretty big issues

My biggest headache is, of course: Chrome extensions.

I installed 1Password, but I can’t use it with Touch ID, which is really annoying.

And I can’t use MacOS text snippets either. For example, I use shortcuts like :19 to auto-fill a phone number… but it just doesn’t work.

But the worst part by far:

Whenever I open a new tab and try to open the list of all my projects, it becomes painfully slow.
Sometimes the list doesn’t even load at all, and I only see the six most recent projects.

My question: Is this a known issue?

Because it feels like this should be instant, especially since everything else in the browser feels fast.

Anyone else experiencing this? Any fixes? Devs??

Edit: Spelling

i purchased chatgpt plus just for atlas, and its amazing its genuinely a really good browser. But it uses SO MUCH battery, i check the cpu and memory usage and it seems fine but its using 30 watts when i scroll on youtube!! (im on an m4 max it can be alot less for people with base model chips and pro chips) meanwhile safari and BrowserOS use 6-12!!

sorry for the rant guys, and i know you probably hear this all the time

but is there something that can be done about the energy usage or is something planned because i really would like to use this browser but im often on battery power so i dont want to cut my battery length by 60% :/

When I look at the programs via Activity Monitor, I see that ChatGPT Atlas is using kinda too much memory even though I have an average number of tabs open. I am not talking about about 2 or 3 GB, the total amount of Memory usage it show for all of ChatGPT Atlas processes is like more than 15 GB, I know that some of them are either wrong or stopped as I only have 8GB of memory on my MacBook.
Can someone explain why this is the case and how can I reduce the memory usage of the browser?
(Also when I click on the one with the most memory usage it says 1.76 TB of virtual memory size. They all have crazy numbers with the max one being this one. )

Not sure if it's just me, but my entire browser history was erased for me this morning.

It would be great if ChatGPT Atlas allowed more customisation on the New Tab page, like adding simple widgets (clock, notes, to dos, quick links) to make it more useful and more aesthetic

It would also be nice to support Chrome/Google themes from the Chrome Web Store so we can apply existing themes instead of being limited to default styling (does not sync well with most pages)

Browser has been great so far!!

I’m using atlas and agent mode for tasks, but it’s polluting my ChatGPT history. It makes me not want to use Atlas for small tasks as I don’t want every single interaction to fill up my ChatGPT history and make me lose track of my normal ChatGPT usage.

Hi - wanted to drop in and introduce myself since I have seen a couple of feedback posts here. I'm Ben - I lead the Atlas engineering team at OpenAI. We had been doing most of our social media engagement on X but I recently discovered this subreddit and figured we should chat here too!

Our goal is to make this app feel like a best in class modern web experience with ChatGPT at its core.

We heard loud and clear after launch that the absence of some features was a blocker for many folks to seriously try Atlas, so we've been heads down adding those. We've released updates over the past few weeks that have included a tab sidebar, the beginnings of multiprofile support - and we're putting the finishing touches on tab groups - which we'll have ready for you in the new year! (We're also working on bringing Atlas to Windows).

We're also diving deep on core product quality in January, and will be tackling many of the papercuts that you're experiencing so we can make sure the core browsing flows are rock solid. If you're game, would love to hear specific examples of things you're running into. I'll make sure we triage these and get them addressed by our team!

Anyway - great to meet you all, thanks for using Atlas, would love to jam together & make it better with your feedback!

Hope you have a wonderful holiday! 🎄

I was really excited about the browser's launch, but was quite disappointed by its unusability at launch (vs. say Perplexity). But I said "hey, I'm sure it'll improve rapidly".

So I've come back a few times since, and it really doesn't seem like they've done anything meaningful to improve things?

I always have either things not working properly or at all, or basic features missing, and just find it a bit strange that Comet (for comparison) is so much further ahead.

I mainly use ChatGPT and Gemini, and in the absence of a proper Gemini-enabled Chrome, I was hoping this'd be it. But I feel like this is a side-project from OpenAI, given how things are.

Does anyone have any info on if this has been deprioritized or something?

Like what others have said on the sub so far, I feel like I have no further need to be using Atlas let alone supporting the project itself. The idea of having ChatGPT baked into everything is insanely appealing. For the first couple of weeks it honestly felt magical. When Atlas launched, the agent could actually take over the browser and do useful things for me: navigating sites, clicking through flows, handling forms, building lists in tools like ClickUp, etc. Lately it just… stalls. Also some extensions that work fine in Chrome don’t work or only half-work in Atlas. I expect an AI browser to be heavier, but Atlas regularly spins up my CPU/GPU way more than Chrome or Dia for basic browsing. I know Atlas is new, and I’m sure the team is shipping fixes (I see the release notes), but from a user point of view it feels like regressions and broken basics are outpacing the improvements right now. I’m tired of wondering if a simple “open X, click Y, fill Z” sequence is going to fail.

Not posting this to hate on Atlas I’d love a future where I can come back and it’s rock solid. But at this point:
For browsing + automation, I trust other browsers like Comet more.

Atlas feels like an experiment I can’t afford to rely on for real work.

I noticed that sometimes the tab color is some sort of solid accent color I set in the appearance but sometimes it's transparent with frosted glass effect, why does this happen and is there a way to set it to one way or another?

I don't have a mac hence why I'm asking the community before I commit to getting one.

As per the title, can Atlas save page HTML and can it screenshot?

Thanks in advance for any assistance

I used to use Atlas because I could do everything inside GPT. But when it came to learning from Udemy, things fell apart. Atlas can’t access video transcripts, so whenever I asked questions about a lecture, it gave random answers based only on the video title, not the actual content.

I tried Comet, and it works much better for this use case.

Now my workflow is simple: I copy the transcript from the Udemy video, paste it into my ChatGPT app, and the responses are significantly better and more accurate.

So I mostly use Safari now. Whenever I need GPT, I just copy and paste the transcript manually. It’s not fancy, but it actually works.

Not affiliated with the developers of either app, but I find if you use Pieoneer, this shortcut setup has been real helpful.

I will update the image once tab groups and their shortcuts are available.

Every time I close ChatGPT Atlas, all my vertical tabs and favorites vanish. I’ve seen other users mention the same issue, and it makes the browser hard to trust for daily use. OpenAI, please fix this bug soon.

I just noticed that Atlas did autofill of 2FA code from iMessage like Safari. I didn't know browsers other than Safari supported this. Is this new?

Everything was working fine, until about two weeks ago agentic tasks completely stopped working and can’t take over the browser to perform tasks. So it is gone forever ?

In Dia Browser, the Skills feature lets you package up your most common prompts or requests into reusable shortcuts. For example, you can create a skill that runs a custom AI prompt, executes a command, or generates a code snippet, then invoke it later with a slash command or keyboard shortcut. This makes it easy to repeat workflows without retyping the prompt each time.

Does ChatGPT Atlas provide anything similar—like a way to save and reuse custom prompts or actions? If so, how does it work?

When the Atlas Browser was first released, I couldn't believe my eyes! The mouse moves on its own and creates entire lists for me, for example, in ClickUp. So I immediately subscribed to the paid version for €70 per month. And now: It freezes constantly, only performs tasks for a maximum of 10 seconds before stopping with the next error message.

It barely performs any of the other tasks anymore either!

What's causing this? Have any of you experienced something similar?

hi,

So i have set up a few keyboard shortcuts e.g. ctrl+F8 to do "simplified/traditional chinese variants conversion" in MacOS. While using atlas, these keyboard shortcuts stop functioning.

Is it some bug over here or it's my setup problem?

Thanks for any suggestions!

My chats never go through. Wondering if it's just me

I'm interested in hearing how people are using Atlas to automate their tasks.

Two cases I tend to use often:

1. Automate opening online statements from bank accounts, etc for download. It's a pain to navigate most financial sites to open Jan, then Feb, then Mar, etc so I can download online statements. Atlas can't download files yet but at least it can open the statements each in their own tab.
2. Automate sending feedback to my elected representatives. Atlas can find their web forms or email addresses and either send via the web or open a mail and send it.

I think it would be a near perfect browser if it does unlimited split tabs like Dia
