Free AI writing detection matters when you need a quick sanity check before submitting or publishing. With Fluideosolutions, CheckMyTxt gives you a free AI text checker built for ChatGPT, Gemini, Claude, and AI-written content. You can paste text or upload a file for instant review, with unlimited words and no sign-up required. Reports include a probability-based AI writing risk analysis (not a final accusation), plus a clear live preview of detection factors.
CheckMyTxt highlights specific sentences that look most “AI-like,” and pairs the authenticity score with reasons such as predictable structure, generic phrasing, repetition, burstiness patterns, and human-experience signals. It’s designed to be fast, mobile-friendly, and easy to interpret—so you can improve your writing instead of guessing.
What you get
Sentence-level risk highlights, human authenticity scoring, readability and burstiness signals, and improvement suggestions you can apply immediately.
How to use it
Paste or upload your document (TXT, MD, CSV, HTML, PDF, DOCX), review the report, then refine parts that feel overly balanced, vague, or repetitive.
Try CheckMyTxt on your next draft and close the loop with clearer, more natural writing.
