Meet Ariel

An AI that actually knows your tank

Most aquarium apps give generic advice. Ariel is different. She sees your water trends, knows every fish in your tank, understands your tap water profile, and remembers past conversations.

  • Personalized advice based on your actual data
  • Natural language logging — just describe what you see
  • Automatic task extraction from conversations
  • Freshwater & saltwater expertise
  • Beginner-friendly explanations, expert-level depth
My ammonia spiked to 1.0 ppm today after adding 3 neon tetras yesterday. What should I do?
That spike is likely from the added bioload of the new tetras. For your 20-gallon freshwater tank, I'd recommend a 30% water change now, dose Prime to detoxify ammonia, and retest in 24 hours. Hold off on feeding today. Your filter bacteria need a few days to catch up — I'll remind you to retest tomorrow.
