AI Perception Analysis and an ask
I built a manuscript analysis tool called FirstReader. The main product is a fiction craft analysis (319 principles from published craft books, chapter by chapter), but one of the features I'm most interested in right now is the free AI Perception Analysis.
Quick version: it scans your manuscript for the specific patterns that readers, editors, and reviewers associate with AI-generated writing. Repetitive sentence structures, filler phrases, paragraph shapes that show up constantly in LLM output. It's not a detector. It doesn't claim to know whether AI was used. It identifies the patterns and shows you where they are so you can decide what to do about them. Fully deterministic, no AI in the analysis itself, genre-aware baselines so romance conventions don't get flagged as AI tells in a romance manuscript.
It now works for both fiction and non-fiction. Free at firstreader.app. If you try it, I'd love to hear your thoughts on it.
The ask:
I'm building out the non-fiction analysis pipeline and I need beta manuscripts to test against. Specifically, I need:
- Narrative non-fiction - memoir, biography, true crime, narrative journalism
- Expository non-fiction - analytical, how-to, textbook, reference
I've already validated the pipeline on prescriptive non-fiction (self-help, instructional) and it performed well. But narrative and expository are structurally different enough that I need real manuscripts to make sure the analysis handles them correctly.
What I'm offering: a free full analysis report on your manuscript in exchange for your honest feedback on what the report got right and what it missed. Your manuscript stays private, never used for training, stored securely behind auth.
If you've got a non-fiction manuscript in either of those categories and you're curious what a craft analysis would look like on it, let me know either in a DM or a comment.
