The Dyson CameraJet is a $499 toothbrush with a camera in it, and yes, that sounds like overengineering, though this is the company that shipped $949 headphones with an air-purifying face visor. It shoots 28 images a second, spots the gaps between your teeth inside 100 milliseconds, and fires a jet of mouthrinse into each one as you pass. Six years and 470,000 dental images went into automating the one part of oral care everybody lies to their dentist about, and the feed streams to your phone, so there is now a camera in your bathroom that you paid $499 for.

Stitch AI is the first embroidery digitizing agent, a job title most people have never heard of and every embroidery shop depends on. Machines don't read pictures, so someone has to turn your artwork into stitch instructions: which areas get satin, which get fill, the angle, the density, the pull compensation that stops the fabric puckering. It runs $10 to $50 a design with a day's turnaround, so shops turn small orders away, and Stitch does it in fifteen seconds and says up front where it will struggle.

Parasocial is a podcast player named after the one-sided relationship you have with people who talk in your ears every night. Naming it that takes some nerve. Paul Geller listens in bed, so the sleep timer works properly and the audio processing exists to rescue decades-old unmastered tape, and its server gets told the second a show publishes, so an episode lands on your phone before you've thought to check, while most players are still polling the feed on a timer.
