Wordtune is an AI-powered writing assistant that helps users improve their writing by suggesting rephrasing, enhancing clarity, and offering tone adjustments for better communication.
Wordtune is an AI-powered writing assistant developed by AI21 Labs that transforms how users approach writing by providing intelligent suggestions for paraphrasing, grammar correction, and tone adjustment across multiple platforms[1][2]. The tool excels at understanding context and meaning rather than simply proofreading, offering multiple rewrite options per sentence—typically 3 or more alternatives—that allow users to select the phrasing that best matches their intended voice and audience[4]. Core capabilities include sentence-level rewriting with contextual awareness, real-time grammar and spelling correction, text expansion and conciseness suggestions, tone customization ranging from casual to formal, and an Ask AI feature that enables conversational writing assistance and content generation from scratch[2][3][5]. Beyond traditional grammar checking, Wordtune distinguishes itself as a comprehensive reading and writing assistant with advanced summarizing capabilities, making it a full-suite solution that supports users throughout their entire writing process—from initial ideation through final refinement[7]. The tool serves writers, students, professionals, marketers, and teams who need to produce polished, engaging content under tight deadlines, with particular value for those crafting everything from emails and social posts to reports, essays, and collaborative documents[1][2]. Available as a browser extension and standalone editor, Wordtune's AI continuously learns from user interactions to provide increasingly tailored suggestions while maintaining high standards for privacy and GDPR compliance[2][4].

High risk across multiple dimensions. Only use with public, non-sensitive data.
The Privacy Policy states data is used 'to improve, enhance and develop the Services, AI21's products and Services and to conduct research' and mentions 'developing, enhancing, training, improving and marketing new products and Services.' However, it does not explicitly state whether user content trains the AI model itself. The language is vague about whether training applies to free and paid tiers equally, and there is an opt-out mechanism mentioned for aggregated data but not clearly for training.
“[Privacy] 'developing, enhancing, training, improving and marketing new products and Services' and 'to improve, enhance and develop the Services, AI21's products and Services and to conduct research'”
The ToS explicitly grants Wordtune a 'perpetual, and irrevocable license to copy, store and use your User Content' for purposes including 'to improve the algorithms underlying the Software and the Services.' The license is 'transferable and sub-licensable,' which is unfavorable. This is a broad, perpetual license that survives termination and allows sublicensing.
“[ToS] 'you give Wordtune (and those it works with) a nonexclusive, worldwide, royalty-free and fully-paid, transferable and sub-licensable, perpetual, and irrevocable license to copy, store and use your User Content in order to (i) provide the Software and Services; (ii) administer and make improvements to the Software and Services (including, to improve the algorithms underlying the Software and the Services)'”
The Privacy Policy lists sharing with 'vendors and service providers' including analytics, payment processors, and customer support, but does not provide a comprehensive sub-processor list or explicit DPA requirements. Sharing with 'corporate affiliates' and 'partners' is mentioned broadly. Analytics data sharing (Google Analytics, Amplitude, Braze) is described but the scope of what constitutes 'anonymized' data is not fully defined.
“[Privacy] 'With our vendors and service providers, including: Email provider and email distribution, Website and product hosting, Payment processor, Customer engagement, Customer support, Product analytics, Website analytic tools, Business intelligence, Advertisement/marketing activities' and 'With our corporate affiliates (e.g. parent and subsidiaries within our group) and/or partners'”
The Privacy Policy states 'Your Personal Data will be stored until we proactively delete it or you send a valid deletion request' but then lists broad exceptions: 'where we are required to do so for compliance with legal and regulatory requirements,' 'for us to have an accurate record,' 'if we reasonably believe there is a prospect of litigation,' and 'in the form of Aggregated Information.' These exceptions are vague and potentially indefinite, creating moderate concern about actual deletion timelines.
“[Privacy] 'Your Personal Data will be stored until we proactively delete it or you send a valid deletion request. Please note that in some circumstances we may store your Personal Data for longer periods of time. These circumstances include: (i) where we are required to do so...for compliance with legal and regulatory requirements...and/or (iv) in the form of Aggregated Information'”
The ToS explicitly states 'You retain all right, title, and interest in and to your User Content' but then immediately grants Wordtune a 'perpetual, and irrevocable license to copy, store and use your User Content' including for improving algorithms. While the user retains ownership, Wordtune's broad sublicensable license to use content for algorithm improvement means the company cannot assert exclusive ownership over how their content is used or derived from.
“[ToS] 'You retain all right, title, and interest in and to your User Content. To the maximum extent permitted by law, by uploading or entering any User Content, you give Wordtune (and those it works with) a nonexclusive, worldwide, royalty-free and fully-paid, transferable and sub-licensable, perpetual, and irrevocable license to copy, store and use your User Content...to improve the algorithms underlying the Software and the Services'”
The Privacy Policy mentions 'appropriate technical, organizational and security measures' and references GDPR compliance mechanisms (Standard Contractual Clauses, Data Privacy Framework), but does not explicitly state SOC 2 Type II, ISO 27001, HIPAA, or other formal certifications. The Privacy Policy references compliance with GDPR and CCPA but does not provide a dedicated security or trust page with published certifications.
“[Privacy] 'We have implemented appropriate technical, organizational and security measures designed to protect your Personal Data' and 'We will comply with the transfers rules under the GDPR, including, by implementing a transfer mechanism, for example, transferring Personal Data to a country declared adequate by the European Commission, executing Standard Contractual Clauses'”
