Grammarly’s been round for over a decade — lengthy earlier than the AI increase reshaped how we write and detect writing. It began as a easy grammar checker and slowly advanced into an all-in-one writing assistant. And now, like virtually each main writing software on the market, it’s received an AI detector baked in.
In the meantime, TruthScan isn’t making an attempt to be a writing assistant. It’s an AI detection suite — constructed particularly to establish AI-generated content material throughout textual content, photos, audio, and video. It doesn’t enable you to write higher; it helps you confirm what’s actual.
So once you put these two aspect by aspect — a standard modifying software versus a full-scale AI detection platform — you get a transparent image of the place the trade is heading. However does Grammarly’s detector truly maintain its personal towards a devoted system like TruthScan? Let’s discover out.
What’s TruthScan?
TruthScan is a complete AI detection suite, designed to identify artificial content material throughout each main medium. It’s not only for textual content — it detects AI photos, movies, voice clones, and even deepfakes.
However for this comparability, we’ll give attention to its AI Textual content Detector, which boasts over 99% accuracy and a sub-100 millisecond detection velocity. It’s constructed for scale — utilized by publishers, educators, and companies to make sure authenticity and transparency in a world the place AI-generated writing is all over the place.
What units TruthScan aside isn’t simply accuracy — it’s context. It doesn’t depend on a single sign (like predictability or perplexity). As a substitute, it cross-analyzes linguistic rhythm, sentence variation, and coherence patterns to establish whether or not one thing was possible written by a human or a mannequin.
In brief: TruthScan is forensic, quick, and constructed for fact verification.
What’s Grammarly?
Grammarly doesn’t want a lot of an introduction — it’s one of the crucial broadly used writing instruments on this planet. What began as a grammar and readability checker is now an AI-powered writing assistant that helps you write, edit, and optimize textual content for tone, model, and professionalism.
Its AI detector is considered one of its latest additions. It was launched in response to the explosion of AI-generated writing from instruments like ChatGPT, Claude, and Gemini. Grammarly’s detector scans for telltale indicators of AI — uniform phrasing, lack of rhythm, and over-structured sentence circulation.
It’s easy to make use of: paste textual content, click on “detect,” and it gives a chance rating (e.g., “possible AI-written” or “possible human-written”). It’s clearly constructed for informal customers — college students, professionals, and on a regular basis writers who simply need to double-check if one thing sounds too AI-like.
However not like TruthScan, Grammarly’s AI detector feels extra like an add-on function than a devoted product. It’s quick, sure, however restricted. You don’t get sentence-by-sentence evaluation, breakdowns, or superior reporting. It’s AI detection in its easiest kind — surface-level, however accessible.
