Bernadette Danaher

I was genuinely impressed by the depth and quality of the feedback I received.
Kerri Stoner
Convent Inception, Historical Fantasy
Story Stream took my novel and pinpointed every issue—and every strength.
David Boevers
Where the Morning Star Fell, Dystopian Sci-Fi
The feedback from Story Stream was very detailed and informative.
Rebecca Schmuck
Tattered, Psychological Thriller
The pacing tool was pretty spot on—it shows you which parts of your story might be moving too slowly or too quickly, and gives ideas on how to fix them.
Sadie Bosque
Gone with the Rake, Historical Romance
I'd highly recommend this software to any writer serious about improving their work
David Boevers
Where the Morning Star Fell, Dystopian Sci-Fi
Not only does Story Stream find the weak spots (info dumps, lagging dialogue, etc.) it gives the author ideas for how to fix them.
