Point your camera at any fish and get an answer in seconds — freshwater, saltwater, or reef, no field guide needed.

Species & classification

Common name, scientific name, family, and category — the details that pin down exactly which fish you found.

Habitat & range

Where it lives, its depth and water type, and how far its range extends across the world’s waters.

How to identify

Key field marks, fin shapes, and colour patterns — plus the look-alike species people commonly confuse it with.

Personal collection

Keep a personal log of every fish you’ve identified, with your own notes attached to each one.

Community gallery

How it works

From photo to fish ID in seconds

Step 01
Take a photo
Capture the fish in good light — a clear side-on shot of the body and fins is all the AI needs.
Step 02
AI does the ichthyology
Our model reads body shape, fin structure, and colour patterns to identify the species.
Step 03
Read the report
Get the name, classification, habitat, behavior, and how to tell it apart from similar fish.
