  "account": "What I Built Walkthrough is a tool designed to help real estate photographers streamline their post-shoot workflow. After capturing 30 to 60 photos of a property, the photographer needs to organize the images in a specific order - starting with the front exterior, followed by living spaces, kitchen, bedrooms, bathrooms, and finally the backyard. Any underexposed or poorly framed shots are also removed during this process.\n\nThe app utilizes an open-weight vision model that runs directly in the user's browser. This model analyzes each photograph and identifies the room it depicts. Once the photos are sorted accordingly, the app removes any dark, soft, or duplicate frames.\n\nThe resulting collection of images is then zipped up and provided to the user. All files remain unaltered, retaining the original quality. Users can continue to manipulate the list - reorganizing photos, selecting different covers, or moving set-aside photos back into the collection. The model only makes the initial layout, but the final decisions are always up to the photographer.\n\nThe target audience for What I Built Walkthrough is primarily solo real estate photographers. This includes professionals who take multiple listings each day, small agencies whose assistants handle listing uploads, and even photographers who occasionally shoot their own properties. The tool also benefits those who previously lacked knowledge of the \"front exterior first\" rule, as illustrated by a case where a toilet was mistakenly chosen as the cover photo.\n\nThe service operates on a subscription basis, costing $9 per month for unlimited listings. This flat rate is advantageous as it eliminates the need to track individual photo counts. A demo version is available, featuring both a real house and an apartment photo set, with some photos deliberately blurred or darkened to demonstrate the app's sorting capabilities. The initial download is around 176 MB for computers with WebGPU support, or 89 MB for others. Post-download, the app functions entirely offline. The code for the tool is available on GitHub under the name 'walkthrough'.",
