AI visibility summary for Grammarly
Grammarly holds the strongest AI visibility position in this three-prompt, three-engine set, with an overall score of 80.3, an 88.9% mention rate and a 55.6% citation rate across nine results. Its lead is clearest against QuillBot (58.5), Scribbr (43.4) and Turnitin (41.1), though competitor pressure is real: QuillBot appears in 66.7% of answers and ProWritingAid draws 26 citations, more than Grammarly's 34 only narrowly exceeds despite far fewer mentions. Engine performance diverges sharply. Google Search is the strongest engine (100% mention and citation, score 94.4), while Google AI Overview mentions Grammarly in every answer but cites it in none, producing a 60.0 score. ChatGPT sits between at 66.7% mention and citation and 64.0. The citation gap is the central weakness: Grammarly's 20.5% share of cited domains leads, yet third-party sources such as techradar.com and languagetool.org are cited in answers where Grammarly is mentioned but not linked. The practical implication is that Grammarly's visibility depends on being named rather than sourced, so its position is more fragile in citation-driven engines than headline mention rates suggest.
