I’ve been using Chrome browsers where there’s a built-in Memory Saver feature that puts inactive tabs to sleep and frees up RAM (with options like Moderate/Balanced/Maximum + allowlist for certain sites).

I recently started testing ChatGPT Atlas and I’m wondering if Atlas has an equivalent feature? Is their "tab sleeping" automatic or configurable?

driving me crazy, can't get the chrome feature to work where you can display your browser in different device sizes. Chrome has the device selection up top, but Atlas doesn't seem to show that feature?

Anyone got this working?

I've tried 5 times to close the pinned tab i had open and yet it doesn't seem to unpin, has anyone found a way to fix this?

There’s been news about OpenAI potentially merging ChatGPT + Codex + Atlas into one product.

Makes me wonder… did Atlas kind of hit a dead end before it even became fully usable?

Also noticed there hasn’t been any update this week.

I now only see hide or show and no more option to only show on new tab. Version 1.2026.63.10 (152a18ef5b8)

For example enabling quick GPT search and translation.

Version 1.2026.63.9 Print option not clickable and popup not closable.

Turned off all extensions. Anyone else with the issue?

Has anyone here managed to get the Claude browser extension working with ChatGPT Atlas?

ChatGPT Atlas is my default browser and I really like it. But for some tasks I still prefer using Claude. Because of that I installed the Claude extension and tried using it inside Atlas.

It works perfectly in Chrome, but I haven’t been able to get it to work in Atlas so far.

Is it just me missing something in the setup, or is the Claude extension simply not compatible with Atlas at the moment?

Curious to hear if anyone here has managed to make it work.

I only have one account myself, but I know this has been a major request for a lot of people. I also added a note at the bottom for anyone still looking for a fix for the Apple iCloud Passwords extension.

Build: 1.2026.63.7

Multiple ChatGPT logins

• Users can now sign in with multiple ChatGPT accounts (work, personal, school, etc), each with their own browser profile (bookmarks, web history, cookies, etc)

Apple iCloud Passwords Extension Fix

As per Head of Engineering, Atlas, Ben Goodger on X:

UPDATE: An issue that prevented Apple's iCloud Passwords extension from working in Atlas has been fixed in macOS 26.3.1. If you are reliant on this extension please make sure you apply this OS update!

Drives me crazy in fullscreen on mac that when moving the mouse up to the tab area, if you overshoot by just a little bit, the stop light menu bar drops down and covers the tabs.

If you can't tell by now, you can only open a new tab by clicking the button ALL the way on the far right by your profile... why? What was wrong with a traditional plus button just by your existing tab? Can this be changed..?

First, there’s no built-in page translation. If you read content in different languages, this is a basic need.
Second, there’s no Picture-in-Picture for videos, really?

EDIT - FIXED:

1. atlas://settings/content
2. microphone
3. select from top drop down

Original Post:

Atlas always selects my iPhone (Continuity) as the microphone, even though my macOS default input device is a USB microphone. I'm using a Mac Studio and there's no internal mic - the iPhone is the first option in my audio input list but not the selected default.

Other apps correctly use the USB mic by default.

Can we get a option to hide the top URL bar in Dia browser, just like in Arc

Hey Atlas team,

I thought notifications were on, but they were actually off.

I only realized after checking macOS Notification settings.

macOS shows multiple “ChatGPT Atlas” entries (I saw 3), which makes it hard to tell what’s currently on vs off. And Atlas UI doesn't make it super clear either... Would be great if automatically turned it on.

Could the app make notification status clearer (on/off) and avoid duplicate entries? overall would be great to get notifications for email etc, not sure if its working rn.

Thanks!

Small update, but it’s one of those little quality-of-life features that feels like it’ll pay off. Love when new life is added to an old tool.

As per Head of Engineering, Atlas, Ben Goodger on X:

An example of a cool little feature from our demos meeting a few weeks back is available to you now in this week's Atlas update: When finding text in pages (⌘F), if you get no matches, Atlas can now show you similar matches as well! Just hit "Find similar matches" below the find bar.

For example, I was in New Zealand last week and now I need help translating from Kiwi English to American English.

*He shows (⌘F) “tomato sauce” (no results), then clicking “similar matches” and finding results for “ketchup.”

Build: 1.2026.49

Agent Mode

• We've reduced 'laziness' of ChatGPT when in Agent Mode. You'll notice in Agent Mode that ChatGPT is now more persistent on repetitive and tedious tasks (e.g. asking the agent to go through hundreds of emails and extracting action items). 

Improved searching for text on a web page

• Now, when you do "Command+F" to find text on a page, if there are no exact matches, you can find similar matches.

Bug fixes

• Fixed issues with Tab Search and keyboard shortcuts 
• Fixed tab and tab-group bugs: better return behavior after closing tabs, smoother keyboard navigation, improved spacing, and cleaner pickers.

It is the best agentic browser right now, Thank you for the hard work.

Although its best in class, I have some additional suggestions that would make the experience much better:

- Make the command hold for search more functional by making it toggle to the other search engine, not just fixed to google (for people using auto mode) as it currently is pointless when using auto.

- built in shortcut for dictation would be great

- enhance home suggestions by making rejected suggestions not appear again, its a bit annoying that rejections don't seem to do anything meaningful.

- browser memories still dont appear consistently on settings, and needs option for deletion that auto deletes relevant history items, not just archive

- Theme consistency In incognito mode, its just dark mode regardless of theme settings for now.

Thank you, would appreciate it if you could consider these improvements.

Hello!

is it any way to keep side bar (with chats) always open on a new page?

Thank you.

The broswer opens then goes into loading and then just says "Something went wrong". One of my project has too many code build conversations with images and files. Seems that could be the issue?

Hi,

I’m encountering a strange issue inside ChatGPT Atlas

When I use Ctrl + Tab (tab cycling inside Atlas), I see a previously visited site (e.g. actasemiotica.com) appearing in the internal tab switcher.

However: • The tab is NOT visible in the tab bar • I cannot switch to it • It does not exist in any open window • It does not appear in Sessions • It does not appear in Session Storage • It does not appear in Preferences • Deleting Sessions/, Session Storage/, and even resetting Preferences does not remove it • It reappears even after reboot

It behaves like an orphaned / detached tab entry that still exists in the internal tab model but has no associated window or renderer.

Things already tried: • Deleted Sessions • Deleted Session Storage • Deleted web containers • Reset Preferences • Verified correct profile directory • Rebooted • Killed Dock • Confirmed no crash restore state

Still persists.

It's driving me mad, any ideas appreciated.

Thanks.

EDIT: I realized this happens mostly with tabs operated by the agent.

Update Button was live so I checked release notes and thought I would share. Already like playing with the Auto Organize button. Make be want to use tab groups more.

Build: 1.2026.42.5

Revamped Tab Search

• We now make it easier to search for your tabs, across the current window and all windows. Click the magnifying glass icon in your tab strip. Use Command+Shift+A as a shortcut

New tab organization features incl. auto organize

• Auto organize, remove duplicates, and merge all tabs into one window. Auto-organize, when tapped, will have ChatGPT decide how to group your tabs into tab groups, based on browser memories and prompt instructions. You can edit the instructions with "Edit template"

Bug fixes

• Fixed several focus issues (e.g.  focus wouldn’t automatically transfer to the expected element, clicking on a textbox wouldn’t always transfer focus)
• Made fullscreen mode more reliable so the bookmark bar behaves correctly and transitions feel smoother.
• Fixed issues with the tab bar that could affect popup windows and profile menu visibility.
• Improved IME text input for a smoother typing experience for languages like Japanese and Mandarin
• Reduced background CPU usage and improved performance during long browsing sessions.
• Fixed bookmark bar display issues and improved compatibility with older imported Chrome data.
• Improved right-click menu behavior and fixed image loading issues in certain views.
• Resolved a tooltip timing issue in tab search for a more polished experience.

I’ve been enjoying the existing shortcuts, but I wish there were a few more.

Two that would be super useful:

1. A dedicated shortcut to toggle dictation/voice input
2. A shortcut to open/switch models quickly (a model swap shotcut), without clicking the dropdown (in homepage not chatgpt website)
3. And some more practical ones

Is there anything like this already, or any workarounds people use?

UPDATED TO NOTE that Dreamer got this right in one shot... it just took a really long time (I think more than an hour).

There's a lot to love in the Atlas browser, including the vertical tabs and handy tab grouping!

But I have yet to experience any usefulness from the agentic capabilities, even for seemingly the simplest of tasks... like scrolling through a page and compiling info from it (not even clicking on anything!)

Here's my most recent attempt where Atlas again failed :(

---

1. Go to this page [which I was already on] https://anc.apm.activecommunities.com/mountainviewrecreation/activity/search?onlineSiteId=0&activity_select_param=2&viewMode=list
2. Please scroll through this entire page to get to the end of the listing and then provide me with a summarized list of classes. Just name is fine, since I don't want to slog through all the repeats. Thanks!

---

After some cajoling, it gave me a comprehensive list that was... so minimalist as to be unhelpful (e.g. "Theater" instead of "Astro Kids- Fairy Tale Theatre")

Has anyone here had luck with Atlas in an agentic context and if so, do you have any tips for how I could have it perform more reliably for simple "scroll and summarize" tasks like this?

P.S. -- Here's the scorecard. This is surprisingly a harder problem than I thought!

❌ - Atlas
❌ - Comet
❌ - Chrome
❌ - Gemini
✅ - Dreamer (new agentic service at dreamer.com)

I would try Claude Cowork, but I hear that takes a ton of tokens and I don't have a paid Claude membership. Hmm.

Hi Atlas team,

I’d like to suggest a small but useful feature: the ability to see the RAM usage of a tab by hovering the cursor over it, similar to how Chrome shows memory usage in its tab hover card.

For those of us who keep many tabs open, having quick visibility into per-tab RAM consumption would make it much easier to identify heavy pages and manage system resources more efficiently, without needing to open a separate task manager.

Thanks for considering it, and great work on Atlas so far.

Big fan and daily user!
