Your pet feels off.
Now you'll know what to do.
At 2am when your pet is acting strange, TailSense helps you assess symptom urgency, know what to watch for, and prepare a vet-ready summary — all in minutes.
Rule-based triage. Smart explanations.
Built-in safety layers.
A deterministic rule engine decides urgency. The Smart TailSense Assistant explains why. A 6-point safety layer validates everything before it reaches you.
Guided Symptom Triage
Select your pet, pick from 10 symptom categories, and answer structured questions. Our deterministic rule engine evaluates urgency — no guesswork.
Smart TailSense Assistant
After the rule engine decides urgency, the Smart Assistant provides breed-specific context, monitoring tips, and personalized explanations using your pet's name.
3-Level Urgency Scale
Watch at Home, Vet Visit Recommended, or Seek Emergency Care — with specific reasons, red flags, next steps, and monitoring checklists for each result.
6-Point Safety Validation
Every response passes server-side safety checks: dangerous phrase detection, urgency contradiction blocking, vet recommendation enforcement, and auto-sanitization.
Vet-Ready Notes
Auto-generate clinical-grade summaries with patient details, presenting complaint, key findings, differential considerations, and recommended diagnostics.
Multi-Pet Profiles
Add pets with breed, age, weight, existing conditions, medications, and allergies. Each check is personalized — puppies and seniors get extra caution.
Triage History
Review past symptom checks with urgency indicators. Filter by pet, view full details with answers, findings, vet notes, and safety metadata.

No more guessing. Just clarity.
Every triage ends with a clear urgency level — determined by our rule engine, not by AI. Each result includes reasons, red flags, next steps, and a monitoring checklist.
Watch at Home
Monitor closely
Things look manageable for now. Keep a close eye on your pet, and reach out to your vet if anything changes.
Vet Visit Recommended
See your vet in the next day or so
We recommend seeing your vet soon. In the meantime, keep your pet comfortable and watch for changes.
Seek Emergency Care
Contact an emergency vet now
Your pet may need urgent attention. Please contact an emergency vet as soon as you can — you're doing the right thing by acting fast.
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.
Tested across 20 medical scenarios including bloat in Great Danes, male cat urinary blockage, seizures, collapse, poisoning, and fractures. The safety layer caught a life-threatening urgency contradiction in a competing model and served a safe fallback — validating the entire architecture.
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.
