The booster comes from our studio production practice: alongside the main voices, one extra track speaks booster lines, affirmations about the listening itself rather than your goal. Absorbing the affirmations deeply, staying open and receptive, keeping every beneficial change. In the app it is one extra voice in the cast: add it on the Voices screen, and it plays center, a touch quieter than the others.
The booster always speaks its own whole set on its own loop and stays out of the Split and Full modes, which only share the main script. It never limits your track length: however long or short the track, the booster simply loops alongside the cast. Its standard set speaks both perspectives, I lines and you lines woven together, and it arrives sized to your script: roughly a third of your line count, and never fewer than 24 lines, so the set stays small enough that its lines actually repeat across a track instead of playing through once. The editor offers both sizes: reset to the sized set, or switch to the full set with one click.
The standard set comes prerecorded from the studio, in the booster's default voice and one female alternative, so adding a booster costs nothing and is ready to play as soon as the clips load. You can keep the standard lines, rewrite any of them, or generate more pairs with AI; your own lines, other voices and other speeds are voiced and billed exactly like any other lines. Removing the booster keeps your edited lines for the next time you add it.
