What Wordtune does
Wordtune is an AI-powered English writing assistant operated by AI21 Labs Ltd., an Israeli-incorporated AI company with commercial operations based in San Francisco. Founded in 2020, the product serves individual writers, students, professionals, content creators, non-native English speakers, and enterprise teams through a freemium subscription model. The platform combines AI-driven paraphrasing, rewriting, grammar checking, tone adjustment (formal/casual), summarization, and translation, delivered via Chrome and Microsoft Edge browser extensions, an iOS mobile app, and a web-based editor. The company has accumulated over 10 million users globally and reports 782 million rewrite suggestions chosen, with Chrome extension ratings of 4.7/5 and an App Store rating of 97%.
The underlying technology is built on AI21 Labs' proprietary language models trained on extensive written-material datasets, generating original rewrite suggestions and contextual alternatives rather than copying existing content. The product suite includes the Spices feature, which verifies facts against at least five sources before surfacing them; YouTube video summarization via the YouTube API; Smart Translate, converting text from ten languages (Spanish, Mandarin, Arabic, Hindi, Korean, Hebrew, Russian, German, French, Portuguese) into English; Smart Synonym vocabulary enhancement; and a Humanize AI capability that refines AI-generated text to sound more natural. A task-specific API is offered through AI21 Studio for third-party developer integration, and the company holds a substantial IP portfolio including 16 granted US patents, Australian and Canadian counterparts, and a registered Wordtune trademark in multiple jurisdictions.
Wordtune operates a product-led growth go-to-market motion with a free tier offering 10 daily rewrites and 3 monthly AI summarizations, plus paid Advanced ($4.89/month annually) and Unlimited ($6.99/month annually) individual plans. A Business tier adds SAML SSO, centralized billing, business support, and team management, available through a self-serve platform or direct sales contact for tailored enterprise offers. Named enterprise customers include Wix, Monday.com, LinkedIn, Electronic Arts, eBay, DoorDash, Google, Dell, Perimeter 81, and SentinelOne, complemented by a 30% discount for academic and nonprofit users. The company is SOC2 Type 2 compliant and runs on Google Cloud Platform infrastructure with supporting vendors including Stripe, Amplitude, Braze, and Intercom.
