Seventy

Seventy turns a phone video of a street into a rabies vaccination survey you can check one dog at a time. Rabies kills over 44,000 people a year, and four in ten are children. We know how to stop it: vaccinate 70% of the dogs in an area and the virus runs out of dogs to spread through. Teams vaccinate millions of dogs a year and rabies stays anyway, because after a drive nobody really knows if they got there. The check is someone walking the streets with a clipboard. Dogs move, so one gets counted twice. Puppies hide, so they never get counted. Marks fade and get misread. One 2025 campaign, measured three standard ways, came out at 47%, 32% and 19%. A drive that failed looks exactly like a drive that worked, until someone is bitten. With Seventy, the surveyor just films the walk on any phone, with nothing to install. From the one word "dog", SAM 3.1 follows every dog through every frame and gives it one number, even through fence bars, even 24 pixels tall at the far end of a road. It finds each dog's ears and enlarges them. Muse Spark reads the mark, and SAM 3.1 looks for it again on its own. If the two models disagree, neither answer counts. Seventy would rather say "can't tell" than guess. In minutes the team has what a clipboard never could give them: coverage against the 70% line with an honest margin, the doses to bring, every missed dog on a map with walking directions, sent to the team's chat in one tap, and a cited report for the district office. Every person in the footage is pixelated. Every number opens to the dogs behind it, so anyone can check the check. And it works. On four street videos counted by hand, Seventy found all 28 dogs and counted each one once. In 28 hand-scored frames SAM 3.1 hit 100% precision and 97.5% recall, and the labels and scoring script are public. It even corrected me: I wrote down two dogs on one clip, SAM kept finding a third, and when I looked, there it was, far down the road. San Antonio just signed a $99,000 deal for one AI count of its dogs. Seventy costs $2 a walk and reads vaccination marks too. I built Seventy from a village in South Asia, where street dogs are on every road and nobody has $99,000 for a count. At $2 a walk, a programme can check every drive on every street, and a ministry can open any number and see the dogs behind it, on the way to the world's 2030 goal of zero deaths from dog rabies. Try it live with no login. It runs real Meta model calls on my API key: https://seventy-world.vercel.app/app/new. Pick a sample walk and watch it run, with the answer written on the card. Or open the walk from the film, with its map, report and every model call: https://seventy-world.vercel.app/app/walks/20dc6230-bdc1-4ed0-adde-cb06688aad41 Seventy gives no medical advice. Demo clips are licensed stock footage, and the film's walk uses a simulated GPS route, labelled on screen.
