Agents don't tell you
why they said no.
StoryGecko does.
Every rejection letter says the same thing. "Not right for my list." "Doesn't align with what I'm looking for." Nothing useful. Nothing actionable. Just silence where feedback should be.
StoryGecko runs a chapter through 9 diagnostic agents — checking tension, escalation, stakes, causality, dialogue, pacing, voice, and theme — and tells writers exactly what a professional reader would flag before the manuscript ever reaches an agent's desk.
The rejection letter that tells you nothing
"Thank you for submitting your manuscript. Unfortunately, this project isn't quite right for my list at this time. I wish you the best of luck placing it elsewhere."
The first chapter tells an agent everything
Within the first chapter, an experienced agent is reading for dozens of structural signals. Most writers know these rules exist. Almost none can hold all of them in their head while writing.
Nine agents. One comprehensive diagnostic.
StoryGecko runs nine specialized diagnostic agents in parallel — each focused on a different craft dimension — then synthesizes their findings into a single, actionable report.
Author submits a chapter
The writer pastes or uploads their chapter, selects their genre, and optionally notes any intentional choices they want StoryGecko to skip.
Nine agents run in parallel
Each agent is specialized: one reads for stakes, one for scene purpose, one for cause and effect, one for dialogue, one for theme. All nine run simultaneously in 15–30 seconds.
A synthesis agent compiles the report
A tenth agent reviews all nine findings and produces a structured diagnostic report: Critical issues, High Impact risks, Moderate observations, and Polish items — with specific, actionable guidance for each.
Iterative scanning closes the loop
After revising, the writer scans again — with previously addressed issues excluded — to surface the next layer of craft concerns. Each pass reveals something new.
What a StoryGecko report looks like
Every report is specific to the chapter — not generic advice, but grounded observations tied to actual moments in the text. This is a real diagnostic run on Chapter 1 of The Hunger Games.
Built for every major fiction genre
Each genre has its own structural contract with the reader. StoryGecko's diagnostic agents understand the specific promises each genre makes — and flags when those promises aren't being kept.
