From San Francisco to 4 Countries: How a Developer Tested 15 AI Tools Across Borders (93.3% Worked, $22,706 Saved)
Sam Rodriguez, 31, Senior Software Developer, San Francisco → 4 Countries
March - October 2024 (8 months)
Challenge: Test if AI tools work globally for remote work
Result: 93.3% tool reliability, $22,706 saved, promotion earned
The Problem: "Will AI Tools Work If I Leave the Country?"
February 2024. Sam Rodriguez sat in his $3,200/month SOMA apartment, staring at his budget spreadsheet.
The numbers were brutal:
- Salary: $95,000/year ($5,540/month after California taxes)
- Monthly expenses: $4,880
- Monthly savings: $660 (11.9% savings rate)
- Annual savings: $7,920
Sam had been following digital nomad accounts on Instagram for months. Friends were posting from Bali, Lisbon, Mexico City—working remotely, saving money, experiencing the world.
But Sam had a question that kept him up at night:
"Will my AI tools work from other countries?"
Sam used 15 different AI tools daily for his software development job:
- ChatGPT for code debugging
- Claude for code reviews
- GitHub Copilot for code completion
- Notion for project management
- Figma for design collaboration
- Slack, Zoom, Loom for team communication
The fears were real:
- VPN blocks (company policy: NO VPNs allowed for security)
- Regional restrictions on AI tools
- Internet speed issues
- Productivity drop
- Getting fired for working abroad
The risk: Leave San Francisco, lose access to tools, tank productivity, get fired.
The reward: Save money, travel the world, maintain career.
Decision: Test it.
The Research: 40 Hours Testing 15 Tools Across 4 Countries
Sam spent 40 hours in February 2024 researching and testing.
Testing methodology:
- Used free VPN (ProtonVPN) to simulate access from target countries
- Tested 15 daily tools from Thailand, Portugal, Mexico, Singapore
- Documented: speed, features available, regional blocks, pricing differences
Target countries chosen:
- Thailand (Chiang Mai) - Low cost, huge nomad community, 12-hour time difference
- Portugal (Lisbon) - Europe, digital nomad visa, 6-hour time difference
- Mexico (Mexico City) - Same time zone as SF, affordable, rich culture
- Singapore - Tech hub, English-speaking, 13-hour time difference
Time investment: 40 hours × $38/hour (Sam's hourly rate) = $1,520 opportunity cost
Test Results: 15 AI Tools Evaluated
✅ SAFE FOR GLOBAL USE (12 tools = 80%):
- ChatGPT Free - Worked in all 4 countries, no VPN needed
- Claude Free - No restrictions in any country
- Google Gemini Free - Global access confirmed
- GitHub Copilot ($10/month) - Worked everywhere
- Notion Free - Cloud sync perfect globally
- Grammarly Free - No geo-blocks encountered
- Canva Free - Universal access
- Figma ($12/month) - Design collaboration worked everywhere
- Google Docs - Obviously global
- Slack (company plan) - Zero issues
- Loom Free - Screen recording uploaded from everywhere
- Calendly Free - Meeting scheduling worked globally
⚠️ MOSTLY SAFE (2 tools = 13.3%):
- Zoom (company plan) - Worked but quality varied by country
- Linear ($8/month) - Occasional sync delays in Thailand
❌ BLOCKED IN 1+ COUNTRY (1 tool = 6.7%):
- Otter.ai Free - BLOCKED in Singapore (worked in Thailand, Portugal, Mexico)
- Workaround found: Google Meet transcription (free, works everywhere)
Overall success rate: 93.3% of tools worked reliably across borders
Sam's conclusion: "The risk is manageable. AI tools are more globally accessible than I feared."
The Decision: $19,040 Potential Extra Savings vs. Zero Savings
Option A: Stay in San Francisco (8 months)
- Monthly expenses: $4,880
- Monthly savings: $660
- 8-month savings: $660 × 8 = $5,280
- Travel experiences: Zero (2 weeks vacation maybe)
Option B: Digital Nomad (8 months, 4 countries)
- Estimated monthly expenses: $2,500/month average
- Estimated monthly savings: $5,540 - $2,500 = $3,040/month
- 8-month savings: $3,040 × 8 = $24,320
- Potential extra savings: $24,320 - $5,280 = $19,040
- Travel experiences: 4 countries, new cultures, nomad communities
The risks:
- AI tool restrictions (93.3% success rate mitigates this)
- Productivity drop (time zones are the real challenge)
- Company finding out (Sam's company allows full remote, no location restrictions)
The upfront investment:
- Travel backpack (Osprey Farpoint 40): $160
- Noise-cancelling headphones (Sony WH-1000XM5): $350
- Portable laptop stand: $40
- International power adapters: $30
- Travel insurance (8 months): $720
- Visa fees: $200

Overall verdict: Time zones matter MORE than tool availability. Choose countries within 6 hours of your team's time zone for best work-life balance.
Framework #1: The Pre-Travel AI Tool Audit System
Sam's 5-Step Process (Do This BEFORE Traveling):
Step 1: List All Daily Tools (Work + Personal)
Create a spreadsheet with columns:
- Tool name
- Purpose (e.g., "Code debugging")
- Daily usage frequency (e.g., "20 times/day")
- Paid or free
- Company-required or optional
Sam's list: 15 tools (ChatGPT, Claude, Gemini, GitHub Copilot, Otter.ai, Grammarly, Notion, Canva, Figma, Google Docs, Slack, Zoom, Loom, Calendly, Linear)
Step 2: Test Each Tool with VPN from Target Countries
Testing tools:
- Use free VPN: ProtonVPN (free tier), TunnelBear (500 MB free)
- Connect to target country servers (Thailand, Portugal, Mexico, Singapore)
- Test each tool for 1 week BEFORE booking flights
What to document:
- Does it load? (Yes/No)
- Speed (Fast/Medium/Slow)
- Features available (Full/Limited/None)
- Error messages (Screenshot)
- Pricing differences (some tools cost more in certain countries)
Time investment: 40 hours total (2.5 hours per tool)
Step 3: Find Backup Tools for Blocked/Limited Tools
If a tool is blocked or limited, find alternatives:
Example 1: Otter.ai blocked in Singapore
- Backup: Google Meet transcription (free, works everywhere)
- Quality comparison: Google Meet = 85% as good as Otter.ai (acceptable)
Example 2: Zoom quality poor in Thailand
- Backup: Loom for async video updates (avoids real-time video issues)
- Quality comparison: Loom = different use case, but reduces Zoom dependency
Rule: Every critical tool needs 1-2 backups documented BEFORE you travel.
Step 4: Verify Company VPN Policy
Sam's company policy: NO VPNs allowed (security risk)
Why this matters:
- If company bans VPNs, you MUST choose tools that work WITHOUT VPN
- VPNs can be blocked by countries (China, UAE, etc.)
- VPNs add latency (slower connections)
If VPNs are allowed: Research which VPN works in target country (NordVPN, ExpressVPN, Surfshark)
If VPNs are banned: Only use tools that work globally without VPN (93.3% of Sam's tools met this criteria)
Step 5: Create a "Tool Passport" Document
What to include:
- Tool name
- Works in: [List of countries]
- Blocked in: [List of countries]
- Workaround: [Backup tool or VPN solution]
- Quality rating: [1-10 in each country]
Share with other nomads: Post on r/digitalnomad, Nomad List forums, or nomad Slack communities.
Update as you travel: Add real-world results (VPN testing ≠ always accurate).
Result: Sam's Tool Passport became the blueprint for 20+ other nomads planning similar trips.
Framework #2: The "No-VPN-Needed" Tech Stack
Sam's Golden Rule: Only use tools that work globally WITHOUT VPN.
Why?
- Company security policy (Sam's company banned VPNs)
- Faster performance (no VPN latency)
- Zero VPN subscription costs ($10-15/month saved)
- More reliable (VPNs get blocked in some countries)
- Legal compliance (some countries ban VPNs)

Framework #3: The Time Zone Optimization Scoring System
Sam's Formula for Rating Countries:
Time Zone Score = (10 - |Time Difference in Hours|) + Meeting Overlap Hours
Interpretation:
- Score 10+: PERFECT (real-time collaboration possible)
- Score 5-9: GOOD (manageable with some adjustments)
- Score 0-4: CHALLENGING (requires async work or night shifts)
- Score <0: DIFFICULT (significant lifestyle sacrifices)
Country Scores (Sam's Team Works 9 AM - 6 PM Pacific Time)
San Francisco (Baseline):
- Time difference: 0 hours
- Meeting overlap: 9 hours (9 AM - 6 PM)
- Score: 10 + 9 = 19 (PERFECT)
Mexico City (GMT-6):
- Time difference: 1 hour (during PDT)
- Meeting overlap: 9 hours (8 AM - 5 PM local = 9 AM - 6 PM Pacific)
- Score: (10 - 1) + 9 = 18 (PERFECT!)
- Result: Sam's HIGHEST productivity (26 commits/week), got promoted here
Portugal/Lisbon (GMT+1):
- Time difference: 9 hours
- Meeting overlap: 7 hours (3 PM - 10 PM local = 9 AM - 3 PM Pacific)
- Work hours: 3 PM - 12 AM local to cover 9 AM - 6 PM Pacific
- Score: (10 - 9) + 7 = 8 (GOOD)
- Result: Manageable, but work ends at midnight (acceptable for 2 months)
Thailand/Chiang Mai (GMT+7):
- Time difference: 15 hours
- Meeting overlap: 4 hours (2 PM - 6 PM local = 9 AM - 1 PM Pacific)
- Work hours: 2 PM - 11 PM local to cover 9 AM - 6 PM Pacific
- Score: (10 - 15) + 4 = -1 (CHALLENGING)
- Result: Doable for 2 months, but social life suffers (working evenings)
Singapore (GMT+8):
- Time difference: 16 hours (13 hours during PDT)
- Meeting overlap: 3 hours (2 PM - 5 PM local = 9 AM - 12 PM Pacific)
- Work hours: 2 PM - 11 PM local to cover 9 AM - 6 PM Pacific
- Score: (10 - 16) + 3 = -3 (DIFFICULT)
- Result: Most challenging, 5% of meetings missed due to late-night schedule
Sam's Time Zone Recommendations
For Long-Term (6+ Months):
- Choose countries with Time Zone Score 8 or higher
- Examples: Mexico, Colombia, Argentina (Latin America), Spain, Portugal (Europe)
For Short-Term (1-3 Months):
- Time Zone Score 0 or higher is manageable
- Examples: Thailand, Vietnam, Indonesia (Southeast Asia)
Avoid for Remote Work:
- Time Zone Score below 0 (requires night shifts)
- Examples: Australia, New Zealand, Japan (if US-based team)
Sam's #1 lesson: "I got promoted in Mexico City because the time zone was perfect. In Thailand/Singapore, I worked nights and felt isolated. Time zones matter MORE than cost of living."
Framework #4: The Cost-Performance Matrix for Country Selection
Sam's Formula: Value Score = (Monthly Savings ÷ Monthly Expenses) × Tool Reliability %
Interpretation:
- Value Score 150+: EXCELLENT (high savings + reliable tools)
- Value Score 100-149: GOOD (decent savings + tools work)
- Value Score 50-99: ACCEPTABLE (some savings + tools mostly work)
- Value Score <50: POOR (expensive + tool issues)
Country Rankings (Sam's 8-Month Results)
1. Thailand (Chiang Mai) - Value Score: 227.8
- Monthly expenses: $1,690
- Monthly savings: $3,850
- Tool reliability: 100% (all 15 tools worked)
- Time zone: Challenging (-1 score)
- Value Score: ($3,850 ÷ $1,690) × 100% = 227.8
- Verdict: BEST for savings + tool reliability, but time zone hard for long-term
2. Mexico (Mexico City) - Value Score: 161.7 (+ Promotion Bonus)
- Monthly expenses: $2,292
- Monthly savings: $3,248 (before promotion) → $3,848 (after promotion)
- Tool reliability: 100% (all 15 tools worked)
- Time zone: PERFECT (18 score)
- Value Score: ($3,248 ÷ $2,292) × 100% + 20 (time zone bonus) = 161.7
- Verdict: BEST overall (2nd highest savings + PERFECT time zone + promotion earned)
3. Portugal (Lisbon) - Value Score: 105.6
- Monthly expenses: $2,695
- Monthly savings: $2,845
- Tool reliability: 100% (all 15 tools worked)
- Time zone: Good (8 score)
- Value Score: ($2,845 ÷ $2,695) × 100% = 105.6
- Verdict: GOOD balance (Europe experience + decent savings + manageable time zone)
4. Singapore - Value Score: 50.6
- Monthly expenses: $3,980
- Monthly savings: $2,160
- Tool reliability: 93.3% (Otter.ai blocked, but workaround found)
- Time zone: Difficult (-3 score)
- Value Score: ($2,160 ÷ $3,980) × 93.3% = 50.6
- Verdict: ACCEPTABLE (expensive + difficult time zone, BUT great for networking/tech scene)
Sam's Country Selection Framework
Step 1: Calculate Value Score for target countries (use nomad community data for expense estimates)
Step 2: Factor in time zone score (add +20 points if Time Zone Score is 10+)
Step 3: Consider non-financial factors:
- Nomad community size (Mexico City/Chiang Mai/Lisbon = huge)
- English proficiency (Singapore/Portugal = high)
- Visa ease (Portugal D7, Mexico tourist visa)
- Safety (all 4 countries Sam visited were safe)
Step 4: Rank countries by adjusted Value Score
Sam's final ranking for SOFTWARE DEVELOPERS working for US companies:
- 🥇 Mexico City (161.7 score + perfect time zone + promotion earned)
- 🥈 Thailand/Chiang Mai (227.8 score + best savings + huge nomad scene)
- 🥉 Portugal/Lisbon (105.6 score + Europe + good time zone)
- Singapore (50.6 score + tech networking + English-speaking)
The Trade-Offs: What Sam Would Tell His February 2024 Self
What Worked Better Than Expected
1. AI tools are MORE reliable globally than feared
"I worried AI tools would be blocked everywhere. Reality: 93.3% worked across 4 countries. Only ONE tool (Otter.ai) was blocked in ONE country (Singapore), and it had a free workaround."
2. Not needing a VPN was LIBERATING
"Company banned VPNs. I thought I was screwed. Reality: 80% of tools worked without VPN. No monthly VPN cost ($10/month saved). No latency. No blocked VPN issues."
3. Productivity didn't drop—it INCREASED
"I feared productivity would tank. Reality: +3.3% commits, +5.6% PRs. I got PROMOTED while in Mexico City. Time zones mattered more than tools."
4. Cost of living savings were REAL and SIGNIFICANT
"Saved $17,426 extra vs. staying in SF. Lived in 4 amazing places. Experienced 4 cultures. Made 70+ international friends."
5. Time zones matter MORE than I thought
"Mexico's 1-hour difference = PERFECT productivity. Thailand's 12-hour difference = doable but isolating. Choose countries within 6 hours of your team for best work-life balance."
What Didn't Work (The Honest Truth)
1. Otter.ai was blocked in Singapore (as predicted)
"I tested it in February with VPN—it showed blocked. Real-world result: blocked. Workaround: Google Meet transcription (free, 85% as good). Lesson: Pre-testing works."
2. Zoom quality varied by country (bandwidth issues)
"Thailand: Some lag 7-9 PM. Singapore: Bandwidth issues. Solution: Scheduled important calls during off-peak times (mornings). Used Loom for async updates."
3. Time zones in Asia were HARD on social life
"Thailand/Singapore: Worked 2 PM - 11 PM. Everyone socializes 7-10 PM. I was working. Felt isolating. Made friends with other nomads working US hours."
4. Singapore was expensive (still saved money vs. SF, but least savings)
"Most expensive country ($3,980/month). Saved least ($2,160/month). BUT: Great tech networking, interviewed at 2 startups for future options. Worth it for 2 months."
5. Not all countries have equal nomad communities
"Mexico City: 100+ nomads at every coworking space. Easy to make friends. Singapore: Smaller scene, harder to connect. Chiang Mai: HUGE scene (best for solo travelers)."
The Biggest Lesson Sam Learned
"Your productivity is determined by time zones, not tools."
In February, Sam worried:
- "Will AI tools work?" (Yes, 93.3% did)
- "Will I get blocked by VPNs?" (No VPN needed for 80% of tools)
- "Will I lose productivity?" (No, productivity increased 3-6%)
The REAL challenge?
- Time zones. Working 2 PM - 11 PM in Thailand felt isolating.
- Work-life balance. Mexico's 1-hour difference = normal schedule. Thailand's 12-hour difference = night shifts.
Better formula for choosing countries:
- Time zone (within 6 hours of team = sustainable long-term)
- Cost of living (aim for 50%+ savings vs. home city)
- Nomad community (larger = easier to make friends)
- AI tool reliability (test BEFORE traveling)
Result: 8 months traveling, $22,706 saved, promotion earned, 93.3% tool success rate, ZERO regrets.
