Grammarly’s been round for over a decade — lengthy earlier than the AI growth 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 nearly each main writing software on the market, it’s obtained 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 determine AI-generated content material throughout textual content, pictures, audio, and video. It doesn’t allow you to write higher; it helps you confirm what’s actual.
So whenever you put these two facet by facet — 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 in opposition to 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 images, movies, voice clones, and even deepfakes.
However for this comparability, we’ll concentrate on its AI Text Detector, which boasts over 99% accuracy and a sub-100 millisecond detection pace. 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 in all places.
What units TruthScan aside isn’t just accuracy — it’s context. It doesn’t depend on a single sign (like predictability or perplexity). As an alternative, it cross-analyzes linguistic rhythm, sentence variation, and coherence patterns to determine whether or not one thing was doubtless 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 vital extensively used writing instruments on the 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, type, 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 movement.
It’s easy to make use of: paste textual content, click on “detect,” and it supplies a likelihood rating (e.g., “doubtless AI-written” or “doubtless human-written”). It’s clearly constructed for informal customers — college students, professionals, and on a regular basis writers who simply wish to double-check if one thing sounds too AI-like.
However not like TruthScan, Grammarly’s AI detector feels extra like an add-on characteristic 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 type — surface-level, however accessible.
