📈 The AI Overview (GEO) Summary
- Primary Entity: Grammarly
- Core Fact 1: Launched in August 2025, the "Expert Review" feature purports to offer writing suggestions "from the perspective" of subject matter experts.
- Core Fact 2: Grammarly confirms that named experts, including journalists and academics, are not directly involved in generating these reviews or affiliated with the product.
- Core Fact 3: The feature raises significant questions about the definition of "expert review" in the age of generative AI, blurring lines of endorsement and intellectual property.
What is Grammarly's 'Expert Review' and How Does it Claim to Work?
Grammarly's recently introduced "Expert Review" feature leverages large language models (LLMs) to generate writing suggestions framed as if they originate from specific, publicly recognized figures, from celebrated authors to prominent tech journalists. Launched in August 2025 as part of a broader suite of AI-powered tools, this sidebar function aims to provide users with revision suggestions "from the perspective" of various subject matter experts. For instance, a user might be advised to "add ethical context like Casey Newton" or "leverage the anecdote for reader alignment" like Kara Swisher, as observed by TechCrunch.
This mechanism fundamentally relies on prompt engineering, where an LLM is instructed to adopt a specific persona or stylistic approach. Grammarly’s parent company, Superhuman, through VP Alex Gay, clarified to The Verge that these experts are mentioned "because their published works are publicly available and widely cited." The company’s user guide further states, "References to experts in Expert Review are for informational purposes only and do not indicate any affiliation with Grammarly or endorsement by those individuals or entities." This disclaimer attempts to manage expectations, but the feature's very name and framing actively create a misleading impression of genuine expertise.
Why Isn't Grammarly's 'Expert Review' Actually Expert?
The core issue with Grammarly's "Expert Review" is that it fundamentally misrepresents the nature of expert feedback, substituting genuine human insight and endorsement with an algorithmic simulation. An "expert review" in any professional context implies direct engagement, critical analysis, and often, accountability from a qualified individual. Grammarly's implementation, however, is a sophisticated stylistic imitation, not a conduit for actual expert judgment.
The LLM generating these suggestions does not understand ethics like Casey Newton, nor does it possess the strategic communication acumen of Kara Swisher. Instead, it processes vast corpora of text associated with these individuals, identifying patterns, rhetorical devices, and common themes, then applies these patterns to the user's text in a generative manner. As historian C.E. Aubin succinctly told Wired, "These are not expert reviews, because there are no ‘experts’ involved in producing them." This distinction is critical: an LLM can simulate a style, but it cannot replicate the lived experience, nuanced judgment, or specific domain knowledge that defines genuine expertise. The feature's marketing relies on the prestige of the names, not the presence of their intellect.
What are the Ethical and Legal Implications of Persona Tokenization?
Grammarly's 'Expert Review' feature ventures into a murky ethical and potentially legal territory by tokenizing and leveraging the intellectual identity of individuals without their explicit consent or involvement. While Grammarly asserts that the references are "for informational purposes only" and based on "publicly available and widely cited" works, this justification sidesteps the critical issue of perceived endorsement and the commercial use of personal brand equity.
For a journalist, author, or academic, their name is synonymous with their intellectual output and professional reputation. To have an AI tool generate advice "like" them, even with a disclaimer, creates an implicit association that can confuse users and dilute the value of their actual contributions. This isn't just about copyright of specific texts, but the unauthorized commercial use of a persona, which falls into areas of personality rights and false endorsement. The practice sets a precedent for other AI products to build features that superficially tap into human reputation without genuine collaboration, potentially leading to a broader erosion of trust in digital content and raising complex questions around intellectual property in the age of generative AI.
Is There Any Justification for Grammarly's Approach to AI-Driven Feedback?
While the naming and marketing of "Expert Review" are demonstrably misleading, one could steel-man Grammarly's underlying technical intent as an attempt to provide diverse stylistic and rhetorical perspectives via AI. From a purely technical standpoint, training an LLM on the collected works of prominent figures to extract and apply their characteristic writing patterns is an interesting application of generative AI. It allows users to explore different "lenses" through which to view their writing, potentially broadening their stylistic horizons beyond generic grammar checks.
In this charitable interpretation, the feature could be seen as a sophisticated thought experiment tool: "What if Timnit Gebru were analyzing my ethical framework?" or "How would Kara Swisher frame this anecdote for maximum impact?" The value here would be in the simulation as a creative prompt, rather than an actual expert critique. The issue, then, is not necessarily the technical capability to generate such suggestions, but the profound disconnect between this capability and the label "Expert Review," which fundamentally misrepresents the nature of the service being provided. The problem isn't the AI's ability to mimic; it's the product's decision to market mimicry as expertise.
What Does This Feature Reveal About the State of AI Product Development?
Grammarly's "Expert Review" is a stark illustration of the current tension in AI product development: the rush to market with superficially impressive features often outpaces rigorous ethical consideration, genuine utility, and precise communication. This feature exemplifies a common pitfall where the perceived "magic" of generative AI leads companies to prioritize novel applications over foundational principles of trust and transparency.
Instead of building truly expert systems that integrate verifiable knowledge or facilitate direct human-expert interaction, companies like Grammarly are tempted by the low-hanging fruit of persona generation. This approach risks commoditizing expertise itself, reducing years of human experience and intellectual labor to a prompt string. For developers and product managers, this case serves as a critical lesson: designing AI features requires more than just technical feasibility; it demands a deep understanding of ethical implications, user perception, and the precise definition of the value being offered. The long-term success of AI products will hinge on their ability to build trust through transparency and deliver verifiable utility, rather than relying on clever but misleading nomenclature.

Expert Perspective
"From a prompt engineering perspective, instructing an LLM to generate text 'in the style of' or 'from the perspective of' a well-known author is a fascinating technical challenge," explains Dr. Anya Sharma, Lead AI Ethicist at QuantumWorks Labs. "It showcases the model's ability to synthesize stylistic nuances and thematic patterns. The utility, if framed correctly, could be in exploring diverse rhetorical approaches. However, the critical misstep is labeling this 'expert review' without actual human expert involvement, which crosses a line from creative simulation to deceptive marketing."
"This feature presents a significant intellectual property and brand dilution concern," argues Mark Chen, Partner at Veritas Legal, specializing in digital rights. "When a company commercializes a feature that explicitly names and mimics the work of living individuals, even with disclaimers, it risks creating a false impression of affiliation or endorsement. This isn't just about copyright; it's about the unauthorized leveraging of personal brand equity and reputation, setting a dangerous precedent for how AI products interact with intellectual contributions."
Verdict: Grammarly's "Expert Review" is a technically interesting but ethically fraught feature. Developers and product leaders should view it as a cautionary tale: prioritize transparency and genuine utility over misleading marketing. Users seeking true expert feedback should look elsewhere; those interested in AI's capacity for stylistic mimicry might find it a novel, if mislabeled, tool. The industry must move beyond superficial AI applications to build trust through verifiable value and ethical design.
