Doubao Reportedly Testing Personal Assistant Product Internally Since April

The internal testing timeline suggests Doubao is treating the personal assistant as a sustained product bet rather than a one-off experiment, building on last year's phone assistant work. That continuity matters because it implies accumulated user-context and integration know-how, not a fresh start. The open question is whether an internal trial from April translates into a public release, and how it would differentiate from the crowded assistant field where distribution, not model quality, often decides outcomes.
