Resea AI

Resea AI is a web writing suite centered on an AI humanizer that rewrites AI drafts into natural text, with multi-detector scoring, keyword locking, citation preservation, academic paper search and a cite checker.

Resea AI is a writing platform built around an AI humanizer. It takes drafts produced by assistants such as ChatGPT, Claude or Gemini and rewrites them so they read like natural human prose. Around that core sit three companion tools: an academic paper search for research, an AI writing editor for drafting titles, outlines and sections, and a cite checker that compares references against real sources to catch errors and fabricated citations. In practice, the workflow starts with pasting text into the humanizer and choosing a style: academic, blog, formal, casual, concise, expanded, or a personal voice learned from samples of the user's own writing. The output can be set to English, Chinese, Portuguese, Spanish, French or German. Results are scored on several detectors shown side by side, including Turnitin, GPTZero, Originality.ai, ZeroGPT and Resea's own detector, so the writer can compare scores before and after a rewrite. Users can also lock specific keywords or technical terms so they survive the rewrite, and the tool detects the citation style in use so reference lists and formatting remain unchanged. The audience is broad. Graduate students and non-native English writers use it to smooth stiff phrasing, SEO teams use keyword locking to keep dozens of posts in one voice, and professionals use it to soften robotic emails or client letters. Among alternatives, many humanizers only paraphrase; Resea positions itself around preserving meaning, terminology and citations while bundling research and verification in the same account. The homepage is candid about limits. Detector outcomes vary by text, final output needs review, and the tool is meant for cases where a school or employer permits AI assistance, not for plagiarism or academic cheating. A free daily allowance makes it easy to test before choosing a paid plan.
