  • Use AI to tidy and brighten the photos of homes for sale

    UK estate agents are using AI to enhance listing photos, from repainting walls and decluttering rooms to adding furniture or lawns, saying it helps buyers see a home's potential. Some listings went too far and were taken down, and one agent now labels every AI-enhanced photo.

  • Appeal a denied medication with an AI tool that drafts the insurance letter

    A patient with Crohn's disease was refused his usual drug and put on a substitute that made him ill, so he used the AI appeal tool Claimable. It drafted a letter built on his symptoms, missed work and cited federal rules, and five days later his doctor's office called to say the original drug was approved.

  • Search Pakistan's unclaimed bank account lists for a family member you've lost

    Pakistan's central bank publishes the names on long-dormant accounts so families can claim the money, but it's 14 million rows across hundreds of spreadsheets. This free tool searches them all at once and handles spelling variations in English and Urdu, the matching runs in your browser so the name you type isn't sent off, and Gemma helps rank matches and drafts a claim letter. The bank still makes the final call.

  • Test how well AI models remember facts before trusting them with your data

    The maker of a football quiz site asked eight models which clubs 200 players had played for and scored every answer against a hand-checked list. Even the best one got about a quarter of its clubs wrong, so the quiz data stays checked by hand. A handy way to measure a model on your own facts before you let it write anything.

    Web pages can hide text people never see, like white-on-white words or tiny fonts, telling an AI assistant to lie or push a product. This open-source tool finds that hidden text and removes the harmful parts, as a browser extension, a page checker, or an API. In the maker's test, a model obeyed hidden orders on 19 of 20 pages, and on none after cleaning.

You can drag things around before applying, it saves a backup so you can undo everything, and new bookmarks get filed as you save them.

    Someone connected Claude Code to the budget Android head unit in their car and, by their account, found an always-listening assistant eating CPU, preinstalled logging apps, and a remote updater.
