BookGlints – Book Review & Trope Scanner

Scan Goodreads, StoryGraph & Royal Road reviews for tropes, themes and dealbreakers that matter to you.

BookGlints is a trope and dealbreaker scanner for book reviews. Tell it anything you want to find or avoid before starting a book, such as slow pacing, strong friendships, romance taking over the plot, an overpowered or overly perfect protagonist, excessive violence, an unfinished series, dungeon crawling, or almost anything else reviewers might mention. BookGlints scans real reviews on Goodreads, StoryGraph, and Royal Road using semantic matching rather than exact keywords. Every result includes a verified excerpt from the actual review, so you can read the context and decide for yourself. If the AI returns evidence that cannot be matched back to the scanned review text, BookGlints discards it. Features include: - Scan the book currently open in your browser - Search for another title without leaving the extension - Batch scan multiple books - Royal Road Read Later import - Local scan history - Three scan depths - Optional Auto-Scan for recurring themes and patterns The core extension is free and uses your own API key from Gemini, Groq, OpenRouter, or OpenAI. No BookGlints account and no subscription are required. Review text goes directly from your browser to the AI provider you choose. It does not pass through a BookGlints server.
