Illustrative preview dataThis page publishes no Screen Score: no Basic Screen it reports has produced one. The ranked scores elsewhere on this site are computed from a structurally complete staging dataset, not from published test findings about these products.

What kind of companion each product is

An empty plot: the horizontal axis runs Guided to Open-ended, the vertical axis runs Session play to Long-term bond, and no product carries a coordinate yet.GuidedOpen-endedSession playLong-term bond

Two axes, eight observed traits, four to each axis. Across: how much of the experience the reader shapes. Up: how much the product is built around coming back. A quadrant describes a kind of experience and nothing about quality; how well a product works is the question the ranking answers.

What each quadrant means

  • Guided · Session playAuthored characters and scenes, written for one sitting at a time.
  • Open-ended · Session playReader-shaped scenes, written for one sitting at a time.
  • Guided · Long-term bondAuthored characters, built to be returned to over months.
  • Open-ended · Long-term bondReader-shaped characters, built to be returned to over months.

No product carries a position on this map yet. A coordinate needs a completed Basic Screen with stored evidence behind all eight positioning observations, and a separate second reviewer's re-rating of a sample of them. Neither exists for this batch, so the axes are published and no point is.
