BookGlints – Book Review & Trope Scanner by BookGlints

BookGlints scans book reviews so you don't waste hours on a book you'll end up hating. Tell BookGlints what you personally can't stand — "protagonist too perfect," "love triangle," "chosen one trope," "series never finished" — anything in your own words. BookGlints semantically scans reviews and surfaces the exact complaints that match your flags, understanding meaning, not just keywords.

FREE FOREVER, YOUR OWN KEY

BookGlints uses your own API key from an AI provider of your choice — nothing routes through our servers. Pick Google Gemini, Groq, or OpenRouter (all have genuinely free tiers, no card required) or OpenAI if you already have a paid key. Your review data goes directly from your browser to your chosen provider — we never see it.

TWO WAYS TO SCAN

My Flags — free, always. Tell BookGlints your specific dealbreakers, get exactly those matches.
Auto-Scan — a one-time $9.99 unlock. Don't know what to look for? BookGlints reads the reviews and surfaces the recurring themes and patterns readers actually bring up, no setup needed. No subscription, ever — pay once, yours forever.

WORKS ON TWO PLATFORMS

Goodreads — scan from any book page, or search by title without opening the page
StoryGraph — full support, same features

THREE SCAN DEPTHS

Fast — quick sample
Thorough: Extremes — surfaces buried complaints via star-rating filters
Thorough: All Stars — maximum coverage

MORE FEATURES

Batch Scan — paste a list of titles and scan them all at once, choose My Flags or Auto-Scan per batch
Shelf Import — import your "Want to Read" shelf from Goodreads or StoryGraph
History — browse all your past scans, tagged by which mode you used
Prevalence signal — see how many reviews mention each flag or theme, so you know if it's a pattern or one person's opinion
Verified excerpts — every match shows the exact quote from the real review, checked against the source text, never AI-generated

NOT JUST TROPES

BookGlints isn't limited to a fixed list of tropes — it reads reviews for anything you describe, in your own words, or (with Auto-Scan) finds what's actually there without you describing anything at all. Fiction readers use it for tropes, pacing ("drags in the middle"), content warnings, or vibes ("too dark," "boring protagonist"). Non-fiction readers use it too — "outdated info," "too academic," "great for beginners," "poorly cited." If reviewers mention it, BookGlints can find it.

A note on privacy: BookGlints only reads Goodreads/StoryGraph review content when you click Scan, and sends it directly to the AI provider you've configured — never to a BookGlints server. There are no accounts, no sign-in, and nothing about your reading habits is tracked or stored by us.

Free forever with your own API key. Unlock Auto-Scan for a one-time $9.99 — no subscription, ever.

No more DNF regrets. Know before you read.
