Voice memo (16:27) — A novel where each character speaks at a different language level (A1, B1, C1). When they interact, the reader gets natural exposure to multiple levels simultaneously. Variant: dual-language characters alternating perspectives.

Why this works: Krashen’s i+1 means multiple characters guarantee the right level for every reader. The same book rewards re-reading as your level improves. More realistic than artificially leveled text.

Could be the flagship product for the graded reader store idea.
