Guided symptom triage
Pick from ten symptom areas and answer plain-language questions. A deterministic rule engine decides urgency — never a guess, never a hallucination.
Pet health triage · iOS & Android
Your pet feels off.
Now you'll know what to do.
It's 2am and something's wrong. TailSense reads the symptoms, tells you how urgent it really is, and hands you a vet-ready summary — in the time it takes to find your shoes.
Safety-validated AI
Photo symptom analysis
What it does
A calm, capable second opinion — whenever you need one.
The rule engine decides how urgent it is. The assistant explains why. Everything after — reminders, handovers, follow-ups — is built to carry you from the scare to the all-clear.
Pro
Photo symptom analysis
Snap the rash, the limp, the eye. TailSense AI describes what it sees in cautious, owner-readable terms — alongside the rule-based result.
Breed-aware explanations
Why this urgency, in your pet's name and breed. Senior dogs and tiny breeds get extra caution, automatically.
Safety-validated results
Every AI reply passes server-side checks: dangerous-phrase blocking, urgency-contradiction guards, and a forced vet recommendation. The emergency core is always free.
Close the loop
Went to the vet? Mark a check addressed and it quiets across the app. Your home screen reflects how your pet is right now — not the 2am scare.
Pro
Medication reminders
Set the times that fit your pet's doses. A gentle daily nudge so the Apoquel never gets skipped — only for pets that actually need it.
Smart check-ins
A day after an urgent check, TailSense asks how your pet's doing. And a happy-birthday note when their big day comes around.
Vet-ready handover
A clean clinical summary — patient details, timeline, findings, questions to ask — ready to share before you walk in the door.
Shareable result card
A polished snapshot of the result you can send to family or your sitter. Your data stays on your device — the image is all that leaves.

Safety Architecture
6-point safety validation. On every response.
The rule engine always decides urgency — the Smart Assistant only explains. Every explanation passes through a server-side safety layer before reaching you. Responses scoring below 40/100 confidence are rejected and replaced with safe templates.
Dangerous Phrase Detection
Scans for 30+ prohibited phrases across diagnosis language, false reassurance, and dangerous medical advice. Blocks "your pet has X" and medication recommendations.
Vet Recommendation Enforced
Every response must mention a veterinarian. If missing, the response is flagged. Your pet's care always points back to a professional.
Urgency Contradiction Blocking
If the rule engine says "Emergency" but the assistant says "can wait" — instant rejection. Confidence drops to zero and a safe fallback is served instead.
Emergency Language Enforcement
For life-threatening cases, responses must contain urgent language like "immediately" or "right now." Missing urgency in emergencies triggers rejection.
Auto-Sanitization
"Your pet has X" is rewritten to "your pet may be showing signs of X." Vet note disclaimers are auto-appended. Diagnosis language is impossible.
4-Level Fallback Chain
Claude Haiku → GPT-4o-mini → Pre-written safe templates → Rule-based results. You always see the triage result, even if every API goes down.

For Veterinarians
Better-prepared clients. Smoother appointments.
TailSense doesn't replace veterinary care — it amplifies it. The rule engine decides urgency, never the AI. Diagnosis language is automatically blocked. Every response points clients back to you.
Clinical-grade vet notes with patient details, presenting complaint, differential considerations, and recommended diagnostics
Save time on intake — clients arrive with structured symptom timelines, answers, and monitoring observations
Diagnosis language is impossible — auto-sanitized to "may be showing signs of" before it reaches the client
Emergency escalation built in — critical symptoms like seizures, collapse, and poisoning route directly to emergency care
Clients arrive informed, not panicked. Every screen says "Always consult your vet" — trust in your expertise is reinforced, not undermined
TailSense is a triage assistant, not a diagnosis tool — it never claims to diagnose and always recommends professional care

The story behind TailSense.

Gabriel Tutor
AI Software Engineer & Solo Founder of TailSense
BS Information Technology, Cum Laude — Aklan State University
Gabriel is a young AI software engineer from the Philippines specializing in mobile development, LLMs, and MCP integrations. With experience building cross-platform apps across the US, Singapore, and Europe — from AI tools to live sports platforms — he combines deep technical skills with a passion for solving real problems. Despite his age, creativity and personal drive are his strongest assets. TailSense is his solo project, built from personal loss and a drive to help pet parents make better decisions when it matters most.
I've lost fur babies before. And the hardest part wasn't just losing them — it was not knowing what to do while it was happening. That helpless feeling when something's wrong and you're just standing there, clueless.
That stuck with me.
So I started building TailSense — an app that walks you through the right questions about your pet's symptoms and tells you straight up: is this an emergency, does this need a vet visit, or is it okay to monitor at home. No more guessing. No more panicking over Google results at 2AM.
Powering it is the Smart TailSense Assistant — a smart triage system built with multiple layers of safety so you can trust the results. It doesn't guess. It doesn't diagnose. It asks the right questions, checks your answers against real medical rules, and gives you a clear next step.
Smart triage, real peace of mind. Always consult your vet.
It won't bring back the ones we've lost. But maybe it can help save the ones still here.
A note from Gabriel: TailSense is a guide, not a substitute for your vet. It's here to help you make better decisions, not replace professional care. And when it's time to visit the vet, you can bring your TailSense result report so your vet can quickly understand what your buddy has been going through — no more scrambling to remember every detail.
