Ask HN: Help recall AI-powered personal assitant showcased recently on HN

There was some thread on HN not that long ago, with a showcase of an AI personal assitant. The case study was, if I recall correct, filling in web forms and searching for apartment rentals fitting specific criteria, which is initiated by a simple text prompt without any additional tweaking.

It was not an assitant in a sense of Alexa or Mycroft, but some kind of an automation. I may be mistaken here, but it may have also come in a form of a browser extension. The showcase demo was most likely either a video or a gif.

Could anyone kindly remind me what exactly the product was and provide a link to the HN discussion?
