OzDive is the dive log that does the rest. Drop in your photos — AI names the fish, writes the log and fills in date, time and place. Your dives become a cinematic profile with a globe of every spot you've dived. LOG A DIVE IN SECONDS Add your photos and OzDive reads date, time and GPS from them. AI identifies the species and drafts a first-person story of the dive — you review it, change what you like, save. 15 AI analyses are free. EVERY CRITTER, ONE GALLERY All your dive photos in one place, sorted by species, country and dive. Star your favourites — they lead your public profile.
