TL;DR — The Paid Map vs the Free Sidekick
Rexby and Karpo both believe in the same thing: generic travel content is broken. They diverge on the fix.
Rexby's fix: hand the keys to creators. Travel influencers package their personal city maps as paid digital products (interactive maps around $29, lifetime access $49, creator video calls $59), sold on a slick mobile platform. You buy a map, you get the creator's actual picks for that city.
Karpo's fix: a free Sidekick in iMessage that knows your taste, runs its own editorial column, and pings you about what's good in NYC, SF, or London this week — no purchase, no per-creator gating.
Different bets on the same insight. On a Cavaliers vs Knicks ECF Game 3 Saturday with Yankees vs Rays at home, Dodgers @ Brewers as the late game, EPL final matchday Sunday 11am ET, and Jason Kidd's name on every NBA podcast after the Mavs firing — the price tag changes the daily-use behavior.
What Rexby Is
Rexby is a Norwegian-built creator marketplace for travel guides. Creators design interactive maps with their personal picks — restaurants, viewpoints, neighborhoods, walking routes — and Rexby handles the storefront, payments, and the mobile reader app.
- Best for: a trip to a specific city where you trust a specific creator's taste.
- Best output: an offline-readable interactive map with the creator's actual picks.
- Strongest moat: creator brand + IP — you buy a guide because you follow the person.
- Pricing: interactive maps around $29, lifetime access $49, video call with creator $59. Custom itineraries range $0-$29 depending on length.
It's a fundamentally different shape from Karpo. Rexby is a marketplace; Karpo is a Sidekick. Rexby sells you content; Karpo runs a thread.
What Karpo Is
Karpo lives in iMessage. There's no marketplace, no creator catalog to browse, no $20 unlock. The Sidekick texts you opinionated picks for the next few hours in NYC, SF, or London, tuned to a taste profile that gets sharper the more you text it.
It runs its own weekly editorial column (Karpo's Finds) pinned to this week's actual signals — Cavaliers vs Knicks ECF tonight, Yankees vs Rays at home, EPL final matchday Sunday, Thunder vs Spurs WCF Game 4 Sunday night, Jason Kidd's post-firing podcast circuit. The editorial layer is the moat; the iMessage surface is the delivery.
The Honest Side-by-Side
Business model — Rexby: per-map purchase (typical map $29, lifetime $49). Karpo: free, no paid tier.
Surface — Rexby: standalone mobile app. Karpo: iMessage.
Content source — Rexby: travel creators' personal picks. Karpo: editorial team + persistent user taste profile + weekly trend integration.
Best for — Rexby: a trip to a city where one specific creator's taste matches yours. Karpo: the city you live in, every week.
Initiative — Rexby: you open the app and browse the map. Karpo: it pings before you ask.
Update cadence — Rexby: when the creator decides to update the map. Karpo: weekly editorial calendar tied to current Google Trends.
Coverage — Rexby: wherever creators sell maps (global, fragmented). Karpo: NYC / SF / London (deep).
Where Rexby Wins
If your travel taste is creator-driven — you follow a specific person whose city picks you trust — Rexby's model is exactly right. $29 for someone's actual Lisbon map is cheap if it saves you four hours of research and lands you in better rooms.
- A focused trip to a city where one creator's taste profile matches yours.
- Offline-capable maps you can carry without cellular.
- Supporting creators directly via paid downloads.
- Coverage outside NYC / SF / London where Karpo's editorial moat doesn't reach.
Where Karpo Wins
Daily use. The recurring weekly question. The behavior that compounds.
Rexby is a transactional surface — you buy a map, you use the map, you put your phone down. Karpo is a persistent thread that's already in your message list. By Saturday at 11am it has already pinged you:
- 'Cavs–Knicks ECF Game 3 at 8 — East Village counter-seat watch party holds seats until 7. Want me to text Mia?'
- 'Yankees vs Rays at home, first pitch 7:05 — Bronx side-street spot opens 6, no line at 5:50.'
- 'Thunder vs Spurs WCF Game 4 Sunday 8 ET — couch setup at home, takeaway pickup window before tip.'
Three pings, all free, all tuned to your taste. You'd have to buy three separate Rexby maps and remember to open them to get a fraction of this. The free tier isn't a positioning trick — it's how the behavior compounds.
Karpo also gets sharper the more you use it; Rexby maps are static unless the creator manually updates.
The Honest Default
Use Rexby when you're going to a city and there's a specific creator whose picks you trust. Use Karpo for the city you live in. The split is geographic + use-frequency: occasional trip vs daily life.
Karpo's free tier is not the discount — it's the design. The product has to be free to be used daily without thought. Rexby's $29-map model works because you only need the map for a week.
FAQ
Is Karpo free? Yes. No paid tier.
How much do Rexby maps cost? Interactive maps typically around $29, lifetime access $49, and creator video calls $59 — exact prices set by the creator.
Can Karpo replace a Rexby creator map? For NYC, SF, and London — yes, for the recurring 'what should I do this week' question. For a one-week trip to Lisbon where you follow a creator who has a Lisbon map, Rexby is still the better fit.
Does Rexby do live recommendations? No, the maps are static creator picks. They don't ping or update based on this week's events.
Which is better for a Saturday in NYC? Karpo, clearly. Free, proactive, taste-tuned, and pinned to this weekend's NBA ECF / WCF / MLB / EPL final matchday signals.
