Atlas Browser Shutting Down? 3 Steps to MIGRATE (2026)

ChatGPT Atlas stops working on August 9, 2026. OpenAI announced the shutdown on July 9, three days before this article’s publication, giving users a 30-day wind-down. Bookmarks, open tabs, and browsing history will not transfer automatically: export your bookmarks to an HTML file now, import them into Chrome, then rebuild your tab workflow there. Your ChatGPT conversations are safe.

Key takeaways

• August 9, 2026 is a hard stop. OpenAI says Atlas may no longer open or browse after that date, and security updates end with it.
• Nothing moves itself. Bookmarks, tabs, history, and logins all need manual export. Only your ChatGPT conversations survive untouched.
• The whole migration takes about 15 minutes before the deadline, and becomes impossible after it.

What Stops Working on August 9

Atlas launched on macOS in October 2025 and lasted under a year. OpenAI’s stated reasoning: the browser is a feature, not the destination. For daily Atlas users, the practical question is what survives.

One note on cookies: Chrome cannot import another browser’s session files, so plan on signing in to your sites again. OpenAI warns that exported cookie files grant account access to whoever holds them; skip them unless you have a specific reason.

Step 1: Export Your Bookmarks From Atlas

This is the one export OpenAI provides a clean path for, and it takes two minutes.

1. Open Atlas and go to the bookmark manager.
2. Choose the export option.
3. Save the file as HTML somewhere you can find it.

Handle open tabs in the same sitting. They do not export as a set, so bookmark the ones that matter into a folder named “Atlas tabs” first; it rides along in the HTML file and becomes your restoration list in Chrome.

Step 2: Import Into Chrome

In Chrome, open the three-dot menu, then Bookmarks and lists > Import bookmarks and settings, select the HTML file, and confirm. Chrome drops everything into an “Imported” folder under Other bookmarks; if your bookmarks seem missing, that folder is where they went.

Then reopen your saved tab folder, right-click it, and choose “Open all”. You are back to roughly where Atlas left you, minus the logins, which you redo site by site as you visit.

Step 3: Rebuild Your Tab Workflow

Bookmarks were the easy part. What Atlas users actually lose is the setup around them: tab groups, profiles, and the sidebar way of moving through a day. Chrome covers some of this natively, with tab groups and, since Chrome 146, built-in vertical tabs.

What Chrome lacks natively is workspace isolation. If you kept separate Atlas profiles or tab groups for work and personal browsing, SuperchargeNavigation (v1.3.3 as of July 2026) rebuilds that in a side panel: named workspaces that each hold their own tab set, an Alt+K command bar that searches open tabs, bookmarks, and history from the keyboard, and session snapshots every 5 minutes (last 50 kept, about 4 hours of undo). The snapshots matter mid-migration, when a wrong click can wipe a half-rebuilt window. Everything is stored locally, no account, free core.

Where the AI Features Went

The assistant side of Atlas is relocating, not disappearing. Deep agentic work moves to the ChatGPT desktop app, which gains a more capable built-in browser with multiple tabs, downloads, and account logins. In-browser help moves to a ChatGPT extension and sidebar for Chrome; availability of both varies by plan, region, and workspace settings as of July 2026, so check your own account.

Where you go from here:

• If you use Atlas daily: export bookmarks this week, not in August. Export becomes impossible once Atlas stops opening.
• If you only need the AI sidebar: install OpenAI’s Chrome extension when it reaches your plan, and skip the desktop app.
• If you came to Atlas from Arc: this is your second browser sunset in a year. The Arc migration guide covers the same rebuild for Arc habits like Spaces.
