Side-by-side comparison
| Category | PetSignalAI | LunaDogAI |
|---|---|---|
| Core positioning | Visible body-language and stress-signal reports for dogs and cats from a photo or short video | AI dog training platform: upload behavior videos, get analysis plus a personalized training plan, AI chat, and video lessons |
| Species focus | Dogs and cats | Dogs only — all ages and breeds, including puppies |
| Platform | Web browser — nothing to install | Also web-based: its FAQ says it is cloud-based and accessible from any phone, tablet, or desktop browser |
| Best use case | An evidence-style read of a concerning moment — is this stress, and does it need a professional? | Working through a defined behavior problem over time: leash reactivity, separation anxiety, barking, recall, obedience |
| Business model | Free first analysis, then $4.99 per report — no subscription | Subscription (monthly or annual) with unlimited video uploads and 24/7 AI chat; cancel anytime, per its pricing page |
| Professional angle | Reports read ears, eyes, tail, and posture together and can be shared with a vet, trainer, or behavior professional | Positions itself as built by professional dog trainers, and Koru K9 presents it as their platform; its terms describe the service as educational, not veterinary advice |
PetSignalAI is a better fit when...
- You have a cat — or both a dog and a cat (LunaDogAI is dogs only)
- You want to understand one specific moment — a photo or clip you just captured — rather than start a training program
- You want a clear risk read (relax, monitor, or call a professional) you can share with a vet or trainer
- You'd rather start with a free first analysis and pay per episode than commit to a subscription
LunaDogAI may be a better fit when...
