Sesame

Ask most voice assistants something they have to look up and you get the tell: a beat of silence, then a fully-formed answer read aloud. Ask Sesame's, and it keeps talking. In a hands-on test, PCWorld's reviewer requested lunch recommendations and watched the app fire off background web searches while the agent carried on speaking — then weave the nearby-restaurant results into its sentence before finishing, no dead air.

It sounds almost like you have a soul. — PCWorld's reviewer, framing their own praise as the worry

That interleaving is the new thing, not the voice itself. Sesame's eerily natural agents went viral in early 2025; this is the company shipping that demo as an iOS app, free in 39 countries, with four personas you can pick between. The trick underneath is latency-hiding: a slower answer is usually a more correct one, but the pause is what makes machine conversation feel like a transaction. Searching mid-sentence buries the wait inside the talking, so the seam disappears.

Which is also the part worth watching. The reviewer's verdict was that it sounds 'almost like you have a soul' — and framed their own enthusiasm as the thing that unsettled them. The closer a free consumer assistant gets to feeling like a person, the more the design itself becomes the question.
