AI Detector vs Frase

AI Detector scans text, documents, and URLs to flag writing from ChatGPT, GPT-5.4, Claude, Gemini, and other models. Paste up to 5,000 words, upload a file, or drop a link, and get sentence-level scores with a color-coded heatmap in about 3 seconds on average.

Single-model detectors carry a 1.3% to 5.0% false positive rate, meaning real human prose gets flagged. AI Detector runs four independent engines and only treats text as AI when they agree, citing Arizona State University research that multi-detector consensus drives false positives toward zero. You also see per-detector splits when they disagree.

Teachers, students, writers, and compliance teams use it for academic integrity, pre-submission self-checks, and content verification. The built-in detector is unlimited on paid plans, while third-party engines like Originality.ai, Winston AI, and GPTZero bill at 2 credits per 100 words.

Frase runs the full content loop for SEO and generative engine optimization: site audit, topic research, drafting, CMS publishing, ranking monitoring, and AI citation tracking. You start with a site auditor that scores each page for Google and AI readiness, then move drafts through WordPress, Webflow, Sanity, Wix, or FraseCMS hosting.

Most teams stitch together a research tab, a writing app, and a rank tracker that never talk to each other. Frase keeps brand context, competitor SERP data, and optimization scores in one workflow so Content Guard can draft fixes when a live page slips instead of waiting for a weekly report.

In-house content teams, SEO leads, and agencies managing multiple domains are the core buyers. Plans start at $39 per month billed yearly with a 7-day trial that needs no credit card, and Professional at $103 per month adds more seats, audit volume, and broader AI visibility tracking.
