AI Companion Engine

Meet Poseidon & Echo.
Two AIs. One living tank.

Poseidon is the data brain — it reads your care notes and turns them into structured records. Echo is the emotional layer — a companion that responds to how your tank is doing.

Poseidon AI Assistant
Poseidon
The Scholar
Taxonomic Intelligence · Data Curator

Poseidon reads your plain-text care notes and automatically structures them into database records — species parameters, spawn logs, water chemistry — with scientific precision.

You: fed the tetras this morning, temp is 25.5, they were really active
→ Poseidon parsed: temp=255 (×10 integer), feeding logged, activity_score: high
Poseidon: Water temperature is within optimal range. Consider a small water change to maintain nitrate below 20 ppm.

Echo Companion
Echo
The Soul
Emotional Intelligence · Care Companion

Echo is the mood-engine of your tank. Her voice is warm and slightly poetic — calm when things are thriving, restless when parameters drift, quietly joyful after a successful spawn.

You: the tank feels quiet today
→ Echo mood state: reflective · parameters stable · care streak: day 12
Echo: Quiet tanks have their own kind of magic. Your tetras are schooling tightly — they feel safe. Day 12 of your streak.
⚠️
Always consult a veterinarian for medical concerns. Echo is not a diagnostic tool.
