AI Detection for Content Writers with Undetectable AI
Blog and SEO drafts flagged by an AI detector get rejected by editors before publication happens. Undetectable AI is a text-scanning workspace, a AI Detection tool, that scans drafts, flags AI-sounding sentences, and rewrites them to read human. Particularly strong at humanizing drafts — not built for long-form research from scratch.

What Undetectable AI Does
Undetectable AI checks text against major AI detectors and rewrites flagged sentences so they score as human-written. The AI Detector scans a draft and highlights the specific sentences a detector would flag, so writers see the problem before submitting rather than guessing at it. The AI Humanizer then rewrites those sentences, keeping the original meaning while changing sentence structure and word choice. A separate AI Image Detector checks whether a picture was AI-generated before it gets shared or published.
A Chrome extension puts detection and humanizing inside the browser, so writers can check text in Google Docs or Gmail without switching tabs.
Main Features
AI Detector
Undetectable AI’s AI Detector scans submitted text and marks which sentences read as AI-generated, matching the patterns major detection engines look for. Writers see the flagged passages directly rather than a single pass/fail score, so edits can target the exact sentences causing a flag instead of rewriting an entire draft.
AI Humanizer
The AI Humanizer rewrites stiff or robotic text into more natural phrasing while preserving meaning and matching a chosen writing level. Undetectable AI applies subtle sentence-structure changes rather than full paraphrasing, so the rewritten text still sounds like the original author instead of a generic AI voice.
SEO Content Writer
Undetectable AI’s SEO Content Writer generates optimized articles directly, combining content generation with the same detection-passing logic used in the Humanizer. Writers get a draft built to read naturally from the start, which cuts the need for a separate humanizing pass on newly generated content.
Developer API
Undetectable AI exposes an API for the Humanizer and Detector so businesses can embed detection and rewriting into their own applications. Agencies use this to build white-label offerings on top of Undetectable AI’s engine rather than sending client text through the public web app.
Use Cases
-
Scale content output for blogs and social media
Content writers use Undetectable AI to produce large volumes of text for blogs and social feeds. The AI Detector and Humanizer catch robotic phrasing before publishing, so high-volume output does not read as templated or machine-written.
-
Create SEO-optimized articles
SEO professionals use the SEO Content Writer to generate optimized articles quickly. Because the same engine checks detection patterns during generation, the output passes AI detectors and reads naturally without a separate editing round.
-
Check and humanize AI-generated business content
Businesses and agencies run client content through the AI Detector and Humanizer before delivery. Undetectable AI’s white-label and API options let agencies package this checking step as part of their own service offering.
Best For / Not For
Undetectable AI is built for people who need existing or newly generated text to pass AI detection before it goes public, and who work with enough volume to justify a recurring word allowance.
Content writers publishing at volume, SEO professionals generating optimized articles on a schedule, and businesses and agencies checking client work before delivery are the audiences Undetectable AI names directly on its own product pages.
Undetectable AI publishes no data on long-form research writing or fact-checking, so anyone needing an AI tool for original investigative content rather than detection-passing rewrites should look elsewhere, and occasional single-document users may find the annual word allowance more than they need.
Pricing
Undetectable AI’s entry plan costs $60 / year, billed annually, for 10,000 words per month, scaling up to $255 / year, billed annually, for 50,000 words per month on the top self-serve tier.

Quick Comparison
WriteHuman is Undetectable AI’s main alternative for rewriting AI-flagged text into human-sounding prose. WriteHuman focuses narrowly on humanizing rewrites without a bundled AI Detector or image-checking tool. Undetectable AI covers detection, humanizing, an SEO Content Writer, and an AI Image Detector in one suite. Choose WriteHuman if a single-purpose rewriting tool fits the workflow. Choose Undetectable AI if detection, humanizing, and content generation need to live under one API.
Verdict
Undetectable AI processes up to 50,000 words per month on its top self-serve plan at $255 / year, billed annually, serving content writers and agencies who need detection-passing text at volume. It fits high-output publishing workflows, not original long-form research writing.
