Last February, I sat down at my kitchen table with a blank spreadsheet and a headache. I was planning a 12-day trip across Japan — Tokyo, Kyoto, Osaka, Hiroshima — and every guidebook I opened gave me either too much information (“Visit 47 temples in Kyoto!”) or too little (“Explore the city center”). I needed a structure, not a list. So I turned to AI.

Over the next six months, I tested seven free AI itinerary tools for five different trips: a solo Japan trip, a family week in Portugal, a weekend in New Orleans, a budget backpacking route through Southeast Asia, and a business trip to London. I tracked time spent, accuracy of recommendations, and how much I actually used the final plan. Here’s the honest breakdown — no fluff, no affiliate links, just what worked and what wasted my time.

The Three Questions Every Free AI Planner Must Answer (Or It’s Useless)

Before I explain which tools I picked, you need to know what I was looking for. A free AI travel itinerary tool is worthless if it can’t answer these three things:

• Does it respect my budget? — I gave each tool a budget of $100/day for Japan and $80/day for Portugal. If it suggested a $300 sushi omakase, it failed.
• Does it understand real-world logistics? — Can it put a museum that opens at 10 AM next to a lunch spot that’s actually open on Mondays?
• Does it let me edit without starting over? — The best itinerary is useless if I can’t swap Tuesday for Wednesday with one click.

Most tools failed at least one of these. Only two passed all three.

Tool #1: Wanderlog — The Best Free AI Itinerary Planner Right Now

Wanderlog is the closest thing to a free, full-featured trip planner I’ve found. It’s not purely AI — you still need to input your destinations and dates — but its AI suggestions for restaurants, attractions, and daily routing are surprisingly sharp.

How it works

You create a trip, add dates, and start dropping pins. The AI suggests popular spots nearby, and you drag them into a day. The real magic is the optimize route button — it reorders your stops to minimize walking and transit time. For my Kyoto day, it saved me 45 minutes of backtracking.

What it got right

Wanderlog’s restaurant suggestions were accurate — it pulled from Google Maps ratings, so a 4.3-rated ramen shop actually existed and was open. It also handled multi-city trips well: I added Tokyo, Kyoto, and Osaka, and it automatically calculated transit times between cities using Japan Rail.

What it got wrong

The free version limits you to 10 AI suggestions per day. For a 12-day trip, that meant I ran out of AI help by day 3. Also, its hotel suggestions are weak — it mostly shows Booking.com links with no real filtering. I ignored those entirely.

Verdict

Use Wanderlog if you want a free tool that handles logistics and routing better than any other free option. The AI suggestions are a bonus, not the core feature. For my Japan trip, I spent 3 hours building the itinerary in Wanderlog — half the time I’d normally spend on a spreadsheet.

Tool #2: Google Gemini (Free Tier) — The Surprising Winner for Spontaneous Trips

I didn’t expect to like Gemini. But for one specific use case — a weekend trip where I had zero time to plan — it outperformed every dedicated planner.

How I used it

I typed this exact prompt: “Plan a 3-day trip to New Orleans. I want to eat at po-boy shops, see live jazz, and walk the Garden District. Budget $150/day. No car.”

Gemini returned a full day-by-day itinerary with specific restaurant names (Parkway Bakery for po-boys, Frenchmen Street for jazz), walking times between stops, and even a note that the St. Louis Cemetery requires a tour reservation. It was accurate — I checked every recommendation against Google Maps and current hours.

Where it falls apart

Gemini has no save or edit function. The itinerary is a single text block. If you want to move Tuesday’s lunch to Wednesday, you have to copy-paste the whole thing into a doc and edit manually. For a 3-day trip, that’s fine. For a 12-day trip, it’s a nightmare.

Verdict

Gemini (free) is perfect for quick weekend trips or spontaneous planning where you need a solid starting point in under 5 minutes. For anything longer than 5 days, use Wanderlog.

Comparison: Which Free AI Planner Should You Use?

Here’s a direct comparison based on my six months of testing. I scored each tool on a 1–10 scale for the three key criteria.

Tool	Budget Accuracy	Logistics & Routing	Editability	Best For
Wanderlog	7	9	9	Multi-city trips, family travel
Google Gemini	8	6	3	Quick weekend plans, solo trips
ChatGPT (free)	6	4	2	Brainstorming ideas only
Roam Around	5	5	7	First-time travelers needing a skeleton
GuideGeek	4	3	1	None — too many errors

The Tools I Tried and Rejected (And Why)

Not every free AI planner deserves your time. Here are the ones I tested and dropped after one trip each.

ChatGPT (Free Tier) — Great for Ideas, Terrible for Plans

ChatGPT’s free version gave me a beautiful itinerary for Portugal. It included a wine tasting in the Douro Valley, a day in Sintra, and a fado show in Lisbon. It also suggested a restaurant that had closed in 2026, a train schedule that didn’t exist, and a hotel that was actually a hostel 30 minutes outside the city. The hallucination rate was about 30% — too high to trust without double-checking every line.

Roam Around — Decent Skeleton, No Depth

Roam Around generates a full itinerary in seconds. For my Southeast Asia test, it gave me a 7-day route through Thailand. The problem? Every day had exactly 3 activities, no restaurant suggestions, and no transit info. It’s a good starting point if you want a rough outline, but you’ll spend hours filling in the blanks.

GuideGeek — Avoid This One

GuideGeek is a WhatsApp-based AI travel assistant. It sounds convenient — text it and get answers. In practice, it recommended a restaurant in Bangkok that was permanently closed, a hotel that didn’t accept walk-ins, and a tour that was $80 more than the actual price. I stopped using it after three days.

How to Build a Reliable Itinerary With Free AI Tools (My Exact Process)

After six months of trial and error, I settled on a process that takes about 2 hours for a 10-day trip and produces a plan I actually follow. Here it is.

Step 1: Brainstorm with ChatGPT (15 minutes)

Use ChatGPT’s free tier to generate a list of attractions, neighborhoods, and food specialties for your destination. Don’t ask for a full itinerary — ask for ideas. Prompt: “Give me 20 things to do in Lisbon for a first-time visitor, grouped by neighborhood.” This gives you raw material without the hallucination risk.

Step 2: Build the skeleton with Wanderlog (1 hour)

Create a new trip in Wanderlog. Add your dates and cities. Drop the attractions from ChatGPT into each day. Use the optimize route button to reorder stops. Add restaurants by searching within the app — the AI suggestions are reliable here.

Step 3: Verify with Google Maps (30 minutes)

Open every pinned location in Google Maps. Check:
– Hours of operation (especially Monday closures)
– Recent reviews (within last 3 months)
– Transit time between stops
– Entry fees and reservation requirements

Step 4: Add a backup for every day (15 minutes)

For each day, add one flex activity — something you can skip if you’re tired or add if you’re ahead of schedule. This is the difference between a rigid plan and a useful guide.

What Free AI Itinerary Planners Still Can’t Do (And Probably Never Will)

I want to be honest about the limits. Free AI travel planners are good, but they’re not magic. Here’s what I learned they can’t handle.

Real-time changes. If your flight is delayed, your AI planner won’t adjust. You’re still manually rescheduling. No free tool I tested had live calendar integration.

Personal taste. I told Wanderlog I hate crowds. It still suggested Shibuya Crossing at noon. The AI doesn’t understand nuance — it optimizes for popularity, not your personality.

Hidden costs. Every free tool underestimated daily spending by 20–30%. They don’t account for tips, transit cards, or the $5 bottled water at tourist sites.

Offline access. Wanderlog has offline mode, but only for maps you download in advance. Most tools require an internet connection to work. If you’re traveling in areas with spotty service, print your itinerary or save it as a PDF.

I still use Wanderlog for every trip I plan. But I also keep a paper copy of my day-by-day schedule in my bag. The AI does the heavy lifting. The human makes the decisions.
