We are working on training an AI that operates on secure, isolated servers with no internet access. Your books will never leave our protected ecosystem or get sent to external AI models. As we train that model, we use models with robust security features and privacy policies.

We operate under fair use doctrine for review purposes, using only legally owned books and generating ratings as legitimate literary analysis.

1. Completely free of explicit or mature themes, featuring clean language, innocent romance (e.g., crushes, flirting), mild conflict without violence, healthy lifestyle choices, educational or positive religious themes, and no mention of LGBTQ+ identities.

2. Contains mild, non-explicit themes, such as light insults, romantic affection (e.g., kissing), fantastical action, unhealthy habits or illness as secondary plot points, faith-promoting stories, minor characters referenced as LGBTQ+ with no detail. This level emphasizes emotional or adventurous storytelling without mature details.

3. Includes implied or moderately described mature themes, such as mid-level swearing, fade-to-gray sexual references, realistic fighting with minimal gore, struggles with mental health or addiction, personal faith crises, characters navigating gender dysphoria, PRIDE themes or events. Content is plot-driven, balancing realism with restraint to maintain narrative integrity.

4. Features infrequent but noticeable explicit content, such as strong profanity, detailed sexual imagery, graphic violence, recreational drug use, negative portrayals of specific religions, or emphasized LGBTQ+ relationships and transitions. While less pervasive than Tier Five, these elements are still prominent.

5. Content is dominated by frequent graphic elements, including extreme profanity, explicit sexual scenes, sexual fetishes, gory violence, glorified harmful behaviors (e.g., drug addiction, alcoholism), graphic disease or injury depictions, satanic or demonic themes or rituals, child gender transitions, graphic LGBTQ+ sex. Pervasive focus on extreme explicit content.

This is covered in the author terms. You are able to appeal the rating and we will review it. Every rating is based on specific and strict criteria. That helps build trust through consistency.

Our goal is to rate every book ever written! With the use of AI, ours is the first scalable solution to book rating and will continue to grow. We are working to partner with publishers to add books more quickly. If you are a publisher or author, please reach out.
