I keep it open 90% of the time. The 10% I close it: watching videos or reading long-form content (want full screen).

3. Browser Memories (AI Learns Your Preferences)

Atlas remembers your browsing habits automatically.

What It Remembers

Sites you visit:

• Frequently visited pages
• Time spent on each site
• Topics you research

Products you search:

• Items you view
• Price points you consider
• Brands you prefer

Your preferences:

• Writing style
• Interests and hobbies
• Work context (if you tell it)

How to Use Memories

Retrieve past searches:

• “Show me the shoes I looked at yesterday”
• Atlas pulls up exact product pages

Find old articles:

• “Find that Rust article I read last week”
• Instant retrieval from history

Get personalized recommendations:

• “Recommend articles based on what I’ve been reading”
• AI suggests content matching your interests

Privacy Controls

View all memories:

1. Settings → Privacy → Browser Memories
2. See complete list of what Atlas remembers
3. Delete individual memories

Delete specific memory:

• Click “Delete” next to unwanted memory
• AI forgets that information

Disable memories entirely:

• Settings → Privacy → Browser Memories → Toggle off
• Atlas stops tracking (existing memories deleted)

Pro Tip: Train Your Memories

Tell Atlas about yourself upfront:

“Remember: I’m a software engineer who works in Rust and Python. I’m interested in self-hosting, mechanical keyboards, and standing desks.”

Atlas uses this context to give better suggestions.

4. Agent Mode (AI Automation for Plus Users)

Requires: ChatGPT Plus ($20/month) or Pro ($200/month)

Agent mode lets ChatGPT control your browser: open tabs, click buttons, fill forms, complete multi-step tasks.

What Agent Mode Can Do

Research tasks:

• “Find the top 5 standing desks under $500”
• Agent searches 3 retailers, compares specs, creates table

Price comparisons:

• “Compare flight prices from SFO to NYC next month”
• Agent checks 5 airlines, presents cheapest options

Data gathering:

• “Research my top 10 competitors and summarize their pricing”
• Agent visits each site, extracts info, creates spreadsheet

Form filling (with approval):

• “Fill out my usual grocery order on Instacart”
• Agent adds items, waits for your approval before checkout

How Agent Mode Works

Step 1: Give command

• “Book a hotel in Paris for March 15-20 under $200/night”

Step 2: Agent asks for approval

• “I’ll search Booking.com, Expedia, and Hotels.com. Proceed?”

Step 3: You approve

• Click “Yes, proceed”

Step 4: Agent works

• Opens tabs
• Searches each site
• Compares results

Step 5: Agent reports back

• “Found 3 options: [Hotel A] $180/night, [Hotel B] $190/night, [Hotel C] $195/night”
• Shows comparison table

Step 6: Final approval (for purchases)

• Agent NEVER completes purchases without explicit confirmation
• You review and approve final action

Safety Features

You see everything:

• Live screen recording of agent’s actions
• Pause at any time (Escape key)

Explicit approvals required:

• Before starting task
• Before any purchases
• Before form submissions

Agent limitations:

• Can’t access passwords (unless you manually enter)
• Can’t see private browsing tabs
• Can’t modify system settings

Real-World Agent Mode Examples

Example 1: Price comparison

Command: “Find the cheapest mechanical keyboard under $100”

Agent:

1. Opens Amazon, Newegg, Best Buy
2. Searches each site
3. Filters by price and reviews
4. Creates table: 5 keyboards with specs, prices, ratings
5. Time: 2 minutes (would take me 20 minutes manually)

Example 2: Competitive research

Command: “Visit my 5 competitors and summarize their pricing models”

Agent:

1. Opens 5 competitor websites
2. Navigates to pricing pages
3. Extracts pricing tiers
4. Creates comparison spreadsheet
5. Time: 5 minutes (would take me 45 minutes manually)

Example 3: Travel planning

Command: “Find flights and hotels for NYC, March 15-20, under $1,000 total”

Agent:

1. Searches flights on Google Flights, Kayak
2. Searches hotels on Booking.com, Hotels.com
3. Calculates total costs
4. Presents 3 complete itineraries
5. Time: 8 minutes (would take me 2+ hours manually)

When Agent Mode Fails

Agent mode struggles with:

• Ambiguous prompts (“Find good laptops” - too vague)
• Sites with CAPTCHAs (can’t solve them)
• Complex multi-step logic (gets confused after 5+ steps)
• Sites requiring login (can’t access accounts)

How to fix:

• Be specific: “Find gaming laptops with RTX 4060 under $1,500 on Amazon”
• Break complex tasks into smaller steps
• Complete logins manually, then let agent continue

Is Agent Mode Worth $20/Month?

Yes if:

• You do repetitive research (5+ hours/month saved)
• You hate manual price comparisons
• You need competitive analysis regularly

No if:

• You rarely do research tasks
• You only browse casually
• $20/month is too expensive

I pay for Plus. Agent mode saves me 8-10 hours/month. Worth $20 for me.

Power User Tips and Workflows

Tip 1: Custom Keyboard Shortcuts for AI Prompts

Create shortcuts for your most-used prompts.

Setup:

1. Settings → Shortcuts → Custom Prompts
2. Create prompt: “Summarize in 3 bullets”
3. Assign shortcut: Cmd + Shift + S

My shortcuts:

• Cmd + Shift + S = Summarize
• Cmd + Shift + E = Explain like I’m 5
• Cmd + Shift + T = Translate to English
• Cmd + Shift + R = Rewrite professionally
• Cmd + Shift + C = Check grammar

Saves 5-10 seconds per use (no right-click menu needed).

Tip 2: Use Agent Mode for Weekly Competitor Analysis

Weekly workflow:

Every Monday, I run: “Visit [competitor1.com], [competitor2.com], [competitor3.com]. For each, summarize homepage value prop, pricing, and any new features since last week.”

Agent creates comparison table in 5 minutes. Would take 30+ minutes manually.

Tip 3: Combine Atlas with Notion for Research Projects

Research workflow:

1. Gather data in Atlas (10-20 tabs open)
2. Use agent mode to create comparison table
3. Copy table to Notion
4. Close tabs (Atlas memories remember sources)

Later, to revisit sources:

• Ask Atlas: “Show me the articles I read about [topic] last week”
• Atlas reopens exact tabs

Tip 4: Use Private Browsing for Sensitive Research

Atlas AI sees all your regular tabs (for context-aware help).

For sensitive topics (medical, legal, financial):

• Use private browsing: Cmd + Shift + N
• Private tabs are invisible to AI
• No memories saved

Tip 5: Train Browser Memories with Context

Give Atlas your context upfront:

“Remember: I’m a freelance writer specializing in tech. I’m researching AI browsers, mechanical keyboards, and productivity tools. I prefer technical depth over beginner explanations.”

Atlas uses this to:

• Recommend relevant articles
• Adjust explanation complexity
• Filter search results

Tip 6: Use Right-Click AI for Learning New Languages

Workflow for language learning:

1. Browse news site in target language
2. Highlight unfamiliar words/phrases
3. Right-click → “Translate and explain grammar”
4. AI translates + explains why that grammar is used

Works better than Google Translate (explains context).

Tip 7: Debug Code Without Leaving Documentation

Coding workflow:

1. Read docs in main window
2. Hit error in terminal
3. Copy error to sidebar
4. Ask: “What’s wrong and how do I fix it?”
5. AI explains error + provides solution
6. Never left the docs page

Tip 8: Use Agent Mode to Monitor Price Drops

Setup a weekly agent task:

“Check prices for [product A], [product B], [product C] on Amazon. Alert me if any drop below [price threshold].”

Agent checks weekly, emails you when prices drop.

(Note: This requires setting up email notifications in Atlas settings)

Tip 9: Batch Process Research with Agent Mode

For multiple similar tasks:

Command: “For each product in [list], find the lowest price across Amazon, Newegg, and Best Buy. Create a spreadsheet.”

Agent processes entire list in one session (10-15 products in 10 minutes).

Tip 10: Use Sidebar for Real-Time Fact-Checking

While reading articles:

Ask sidebar: “Is this claim true? [paste claim]”

AI fact-checks using web search (if enabled) or knowledge base.

Perfect for reading news/opinion pieces.

Troubleshooting Common Issues

Issue 1: Atlas Crashes on Launch

Symptoms: Atlas opens briefly, then crashes

Fix:

1. Quit Atlas (Cmd + Q)
2. Open Terminal
3. Run: rm -rf ~/Library/Application Support/Atlas/Preferences
4. Relaunch Atlas

This resets Atlas to defaults. Fixed 90% of crashes I’ve seen.

Issue 2: AI Sidebar Doesn’t Respond

Symptoms: Sidebar loads but ChatGPT doesn’t answer

Fix:

1. Check internet connection (AI runs in cloud)
2. Sign out and back in: Settings → Account → Sign out
3. Clear cache: Settings → Privacy → Clear browsing data
4. Restart Atlas

Usually fixes in 30 seconds.

Issue 3: Agent Mode Gets Stuck

Symptoms: Agent starts task but doesn’t complete

Fix:

1. Press Escape to stop agent
2. Refresh page (Cmd + R)
3. Restart with more specific prompt

Example of vague vs specific:

• ❌ Vague: “Find flights to NYC”
• ✅ Specific: “Find non-stop flights from SFO to JFK on United.com for March 15, under $400”

Issue 4: Chrome Extension Won’t Install

Symptoms: Click “Add to Chrome”, nothing happens

Fix:

1. Check if extension is Manifest V3 compatible (old extensions may not work)
2. Try incognito mode: Cmd + Shift + N, then install
3. Disable conflicting extensions temporarily
4. Install directly from Chrome Web Store (not third-party sites)

Issue 5: Browser Memories Show Incorrect Info

Symptoms: Atlas remembers wrong preferences

Fix:

1. Settings → Privacy → Browser Memories
2. Find incorrect memory
3. Click “Delete”
4. Retrain: Tell Atlas correct info (“Remember: I prefer [X]”)

Memories improve over time. Delete wrong ones early.

Issue 6: High RAM Usage

Symptoms: Atlas uses 2+ GB RAM, Mac slows down

Fix:

1. Close unused tabs (each tab = 50-100 MB)
2. Disable unused extensions: Settings → Extensions
3. Clear cache: Settings → Privacy → Clear cache
4. Restart Atlas weekly (closes background processes)

Atlas uses same RAM as Chrome (~100 MB per tab).

Best Practices for Maximum Productivity

1. Be Specific with Prompts

Bad: “Find laptops” Good: “Find gaming laptops with RTX 4060, 16GB RAM, under $1,500 on Amazon and Newegg”

Specificity = better results from agent mode.

2. Use Context-Aware Right-Click Instead of Sidebar

Why: Right-click automatically includes page context. Sidebar requires you to explain context.

Faster: Highlight text → right-click → “Summarize” Slower: Copy text → open sidebar → paste → “Summarize this”

Save 5-10 seconds per use. Adds up over 50 daily uses.

3. Clear Browser Memories Monthly

Memories accumulate clutter. Monthly cleanup:

1. Settings → Privacy → Browser Memories
2. Delete irrelevant memories (“Products I searched but never bought”)

Keeps recommendations relevant.

4. Don’t Rely 100% on Agent Mode

Agent mode is a research assistant, not a decision-maker.

Good workflow:

• Agent gathers data → You analyze → You decide

Bad workflow:

• Agent gathers data → Agent decides → You blindly accept

Use agent mode to save time on tedious tasks. Make decisions yourself.

5. Train Browser Memories Early

Tell Atlas about yourself in the first week:

• Your profession
• Your interests
• Your preferred writing style
• Topics you research frequently

Memories improve over time. Good training = better assistance.

Conclusion: Master Atlas in One Week

Day 1: Install Atlas, import bookmarks, explore sidebar Day 2: Practice right-click AI on 10 articles Day 3: Set up browser memories (tell Atlas about yourself) Day 4: Install favorite Chrome extensions Day 5: Try agent mode (if you have Plus) on simple task Day 6: Create custom keyboard shortcuts Day 7: Build your first productivity workflow

By day 7, Atlas will feel natural. You’ll wonder how you ever used a browser without AI.

Most impactful features (in order):

1. Right-click context-aware AI (use 20+ times daily)
2. Persistent sidebar (eliminates tab-switching)
3. Agent mode (saves hours on research, if you have Plus)
4. Browser memories (gets better over time)

Pro tip: Don’t try to use every feature at once. Master right-click AI first (week 1), then add agent mode (week 2), then optimize with shortcuts (week 3).

Atlas is the most capable AI browser available. But power without knowledge is wasted. Use this guide to unlock its full potential.
