PlotCatalyst Echo turns the time you already have — driving, walking, doing dishes — into focused editing passes on your novel, screenplay, or long-form draft.
PlotCatalyst Echo is a manuscript review and editing companion for novelists, screenwriters, and long-form writers who want to HEAR their work the way a reader will. Pacing problems, awkward dialogue, and overused phrases that hide on the page jump out the moment they're read aloud — capture the reaction in a voice note anchored to the exact paragraph, then come back to act on it.
Turn driving, walking, and commuting time into focused editing passes.

CAPTURE NOTES THE MOMENT IT MATTERS

• Optional auto-stop timer (15s, 30s, 60s, 90s, 2min, or custom up to 5 min) with an animated countdown ring around the mic.
