Our Story
Built for the reader who cares what they pick up.
BookLens started with one family, one problem, and a growing stack of abandoned novels.
My wife loves to read. She reads through entire genres, devours series, and always has a book going. But she has one rule: she won't read books with profanity.Not as a moral stance — just a preference. Strong language pulls her out of a story, and she'd rather not deal with it.
The problem? Most books don't come with a content label. She'd buy a book, read half of it, hit a scene she wasn't expecting, and put it down. Again and again.
Common Sense Media exists, but it's shallow and inconsistent. Goodreads reviews are a mixed bag. There was no resource that said, simply: this book contains 14 instances of the f-word, 3 moderately explicit scenes, and a suicide subplot.
So I built one.
BookLens uses AI to read entire books — every page, not a summary — and produce detailed, structured content ratings. Not to tell anyone what to read. Just to let people make the choice themselves, with complete information.
That's the whole idea. See inside before you read.
What we believe
Ratings are information, not censorship
BookLens tells you what's in a book. What you do with that information is entirely your business. We don't recommend reading or not reading anything.
Every reader deserves specifics
"Some language" is useless. Knowing there are 3 instances of mild profanity vs. 140 instances of the f-word is the difference between a useful rating and noise.
The AI should do the work
Sampling a chapter tells you about one chapter. Scanning for keywords without context misses everything. AI reading the whole text is the only honest approach.
Privacy matters for publishers
We never store manuscripts. The file is deleted immediately after analysis. We only keep the rating — not the words that produced it.
Who BookLens is for
Parents
Choosing books for their kids — or deciding whether a book their teen wants to read is appropriate for their family.
Sensitive readers
Adults who avoid certain content for personal, religious, or health reasons. They deserve the same careful information parents use.
Book clubs & teachers
Selecting titles for a group means knowing what everyone is walking into. BookLens surfaces the things you'd want to mention before your next meeting.
Faith-based readers
Readers from many traditions have content standards that most book review sites simply don't address. BookLens does.
