fishline.ai - AI Fish Measure

Put your hands down.

For as long as there have been fish stories, they have had one measuring tool: two hands held apart, a little wider every year. fishline.ai retires it. Hold the fish up like you already do, take one photo, and pick what you want to know: the weight, the length nose to tail, about how old it is, or all three.

Every result shows its work. Open the Measurement sheet for every number and how it was read: the ranges, what was in the frame for scale and how sure it is of the species. You tell the story. We bring the number.

WEIGH IT
Every fish gains a pound on the drive home. This one won't. fishline.ai estimates the weight from the species, the length and the build of the fish.

MEASURE IT
Nose to tail. Not hand to hand. Tell fishline.ai what is in the frame for scale, your hand, a bump board, a tape, and it measures the length against it. Took a length yourself? Type it in and fishline.ai uses it. Every photo is checked for a fish before a credit is spent.

AGE IT
The one number no fish story ever had. Pick age and fishline.ai estimates about how old your fish is, in whole years, from its species and size. The growth projection comes with it: what she could weigh in one, two and three years if she swims.

SPECIES
fishline.ai names the species, so every number is read against the right fish.

CATCH LOG
Every fish you measure, saved with its photo, its numbers, the water and the date. Public or private, your call.

COMMUNITY
Post a catch with its numbers on it. See what other anglers are measuring, follow the ones you like and message them. Report or block anyone, any time.

GUIDES AND CHARTERS
Find guides and charter captains by state, species and trip type, and book a trip. Guides can list their service from the app.

SPOTS AND THE CATCH MAP
A lake, a river or one bend in a creek: each Spot keeps its own catches, its average and your personal best. The Catch Map rolls shared catches up by state and county. Never a pin, and photos lose their GPS when they upload. Share the fish, not the spot.

HOW THE NUMBERS WORK
Every number is an estimate made from your photo by an AI vision model on our server. Something of known size in the frame tightens it. A clear side on shot in good light beats a dark or angled one. For a weigh in, a state record or a size limit, use a certified scale or a board.

CREDITS AND PLANS
Every angler gets 5 free credits a month. Pick weight, length or age for each photo, 1 credit each. Species comes free with any of them, and the growth projection comes with age. If a number can't be read, its credit comes back.
Pro: 10 credits a month, Spots, personal bests and the full Catch Map. Elite: unlimited, no credits counted, fair use 30 photos a day, and 7 days free on the yearly plan. Plans renew automatically until you cancel in Google Play, Subscriptions.
