Built for honest hosts in an era of stricter rules
A fraud cheater changed the rules.
You're paying for it.
In April 2026, Airbnb rewrote the AirCover evidence bar to stop a $16,000 AI-doctored damage claim. Honest hosts now have to prove their photos aren't faked — every claim, every time. Jin gives you that proof at the shutter, before the photo ever leaves your phone.

The reason your honest claims still get denied
Airbnb says "insufficient documentation."
You took fifteen photos.
The April 20, 2026 ToS update was written to stop AI-fabricated damage claims. Good intention, brutal side effect: the bar is now so high that ordinary phone photos — the camera roll, the screenshots, the iMessage-compressed JPEGs — don't clear it anymore. Honest hosts pay the freight for fraudsters.

From damage to defended — in 90 seconds
Four steps. Ninety seconds. Receipt-ready.
- 01
Tap Damage on the Hosts dock
One red button. Always one tap away. The clock starts; the 10-minute payout window is visible up top.
- 02
Capture — natively, with intent
Wide shot, medium, detail. SHA-256 hashed locally before the bytes leave the device. EXIF preserved end-to-end.
- 03
Server verifies; R2 stores raw bytes
Server-side hash compared to client hash. Match → file stored to Cloudflare R2 untransformed. Mismatch → rejected with a hash-mismatch error. Your claim becomes math, not opinion.
- 04
PDF packet + guest message — auto
AirCover-shaped PDF with cover, photo pages, chain-of-custody appendix. Suggested guest message with the right cadence. Copy, paste, file. Done.
Built for the moment AirCover says no
Finally — the proof AirCover can't dismiss.
-
Native iOS camera, never the library
Photos imported from your camera roll are EXIF-stripped by every messaging app between you and Airbnb. Jin · Hosts captures directly via AVCapturePhotoOutput so the metadata chain is intact from shutter to submission.
-
SHA-256 verified at capture AND receipt
Hash computed in iOS the moment shutter fires. Hash re-computed server-side at receipt. Any byte tampered with in transit fails the equation. The PDF appendix shows every hash, so reviewers see chain-of-custody, not promises.
-
Cloudflare R2 immutable storage
Photos land in R2 with the original bytes, never re-encoded. The original file is the evidence; everything else is metadata. No proprietary format, no vendor lock — your evidence remains exportable forever.
-
Zero AI imagery — compliant by construction, not by promise
Built to Airbnb's April 20, 2026 evidence policy six months before it took effect. No upscaling, no denoising, no AI enhancement on the evidence path. The system rejects a blurry shot rather than alter it. The math is the moat.
Alpha · 50 Superhosts
Fifty Superhosts will define what wins.
Be one of them.
We're choosing fifty hosts who've fought an AirCover denial —
and lost. Your battle scars shape what ships. Free for life if
you stay. Founder pricing locked in if you leave. Direct line
to me, not a support queue.

We email when we have something real to show. No marketing automation.
Honest answers
Questions other hosts asked first.
Does this work with Hostfully / Guesty / Hospitable?
Not via direct API integration yet. The capture + claim packet flow works independently — you generate the PDF on-device and attach to Airbnb's claim form like you would today. PMS integrations come in v1.1+ based on what the alpha cohort tells us matters most.
iPhone-only? When Android?
iPhone-only for alpha because the AVCapturePhotoOutput pipeline is the foundation of the chain-of-custody guarantee. Android's CameraX has the equivalent surface; we'll ship it after the iOS alpha closes Sean-Ellis green.
How is this different from HostThrive?
HostThrive sells coaching and a Google Sheet checklist. Jin Hosts is the software equivalent: same outcome (winning the claim) via different mechanism (cryptographic chain of custody + auto-generated packet). Many of our alpha hosts were HostThrive customers first; we're not competitive — we're complementary at the workflow layer.
What about Truepic? Isn't this their thing?
Truepic is enterprise. $1,450/month minimum. Their lowest-tier customer is a $50M insurance carrier, not a host with three units. We use the same primitives (SHA-256, EXIF preservation, immutable storage) but priced for hosts and shaped for AirCover. Truepic could build what we built. They haven't, because they sell to procurement teams. We sell to you.
What about ProofMi or Proofr?
ProofMi is the closest — solo developer, smart signature story, no immutable storage and no AirCover-shaped output. Proofr advertises "AI-powered" damage detection, which is the exact thing Airbnb just banned. We're alone in shipping (a) chain-of-custody hashing and (b) the AirCover-shaped claim packet and (c) explicit non-use of AI on the evidence path. You can verify all three in the App Store listing on launch day.
What about iOS 19's native Content Credentials?
Apple is shipping C2PA-signed photos natively, probably in iOS 19 or 20 (2027–2028). When it lands, our hashing pillar becomes table stakes. By then, our moat will have migrated to outcome data — "your claim approval rate on Jin is X% higher" — instead of cryptographic plumbing. We knew this clock when we started building. The first 12–18 months are about proving we win claims, not just generate hashes.
What will this cost when it leaves alpha?
Pricing is one of the things the alpha will tell us. Current anchor points we're testing: $19/mo single property, $39/mo unlimited, $19/door for multi-portfolio. Alpha hosts get founder pricing locked in.
What about insurance / underwriting?
We stay on the evidence side of the line for v1. You file your own claim; we make the evidence airtight. Underwriting or claim guarantee products require state-by-state licensing and are explicitly out of scope until the evidence layer is proven at cohort scale.
