Live App | Free to use (bring your own Anthropic API key)
StoryFix is a purpose-built diagnostic tool for fiction writers who are stuck. Instead of opening a blank ChatGPT window and hoping for useful feedback, StoryFix asks the right questions and gives you structured editorial analysis — the kind a developmental editor would charge $50-200/hour to provide.
Describe where you're stuck and what feels broken. Get: root cause analysis, the structural reason the problem exists, three concrete fixes ordered from least to most disruptive, a diagnostic question to test your solution, and one common mistake to avoid.
Paste a character description and the specific problem. Get: core diagnosis, the missing dimension, motivation surgery (want vs. need vs. wound), three concrete fixes, a scene suggestion that would reveal the missing layer, and a red flag about what will cause bigger problems later.
Paste a scene and describe what isn't working. Get: what the scene is actually doing vs. what it should do, three structural notes with quoted examples and specific fixes, line-level observations, what to keep, and the revision question that unlocks the whole thing.
Paste a dialogue exchange with character context. Get: subtext audit (where characters say too much or too little), voice distinctiveness analysis, three revision strategies with examples, two modeled line alternatives, and a clear definition of the underlying tension the dialogue should dance around.
Describe your world's rules and the inconsistency you've found. Get: classification of the problem type, how much readers will notice, three fix approaches with downstream implications, a recommended solution, ripple effects to check elsewhere in the manuscript, and a rule refinement to prevent the problem recurring.
