The pitch: it's free to use, handles everyday tasks like a typical assistant, and does not require sending personal data to the cloud to work. Underdog enters a space already occupied by Instinct and Muse, two assistants that have made similar privacy promises. Wen is positioning Underdog as the most private option of the three.\n\nOn-device processing is the only way to make a 'private' claim actually mean something, since nothing leaves the hardware for a remote server to log, train on, or leak. If Underdog delivers on both fully local processing and real capability without a subscription, it puts pressure on Instinct and Muse to justify why their versions of privacy fall short by comparison.\n\nPlenty of AI tools have promised to do everything on-device before learning that 'capable' and 'local' don't always fit on the same chip. We'll see if Underdog is the exception.","[\"on-device ai\",\"privacy\",\"ai assistants\"]","2026-10-06T20:47:01.000Z","2026-10-07T13:11:19.617Z","2026-10-07T13:11:24.297Z","published",null,[],"ai",[26,27,28],"on-device ai","privacy","ai assistants",[30],{"name":31,"url":32},"TechCrunch","https:\u002F\u002Ftechcrunch.com\u002F2026\u002F10\u002F06\u002Fsilicon-valleys-ai-wunderkind-launches-underdog-the-most-private-instinct-muse-competitor-yet\u002F",0,{"sections":35},[36,40,45,50,55,60,65,70,75,80,85,90,95,100],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",6375,"2026-10-07T18:30:57.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",902,"2026-10-07T19:53:42.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Policy","policy",473,"2026-10-07T18:23:21.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Deals","deals",453,"2026-10-07T23:58:31.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",222,"2026-10-07T21:19:54.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Science","science",186,"2026-10-06T21:20:39.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Consumer Tech","consumer-tech",173,"2026-10-07T17:41:41.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Software","software",113,"2026-10-07T18:10:00.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Startups","startups",112,"2026-10-07T23:36:57.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Dev Tools","dev-tools",105,"2026-10-07T16:59:11.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"General","general",59,"2026-10-07T21:16:18.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"Gaming","gaming",56,"2026-10-07T12:00:00.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Reviews","reviews",33,"2026-10-05T11:57:17.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"How-To","how-to",8,"2026-10-05T09:00:00.000Z"]
