A reading room for your draft
Hear your manuscript before anyone else does.
Your eyes have read this draft a hundred times. Your ears haven't. PlotCatalyst Echo reads your novel aloud in a natural voice so the soft spots show themselves — and lets you capture every reaction the moment it happens, anchored to the exact paragraph.
What it does
Listen, don't just read
Import a .txt or .docx. Chapters get detected automatically. Press play and your manuscript is read back to you in a natural narrator voice. The current paragraph is highlighted as you go.
Notes, anchored to the exact spot
Tap a button — type or speak. The note remembers the paragraph you were on. Open it later and jump straight back to that passage.
Car Mode
Big buttons, big mic, no reading required. Listen on your commute or your morning walk and dictate every reaction hands-free.
AI editor in your corner
Ask for a rewrite of any paragraph, run a redundancy sweep across the whole book, or generate metadata and cover art — all without leaving the manuscript.
Premium voices
Use your device's built-in voice for free, or bring an ElevenLabs or Kokoro key for studio-quality narration that doesn't sound like a phone.
Yours, on your device
Manuscripts and notes live locally. Back up to your own Dropbox when you want an off-device copy.
Made for the revision pass
Most writing apps are built for the first draft. Echo is built for everything that comes after — the slow, careful, ear-driven work of turning a draft into a book. The thing your editor is going to say first? You'll hear it before they do.
