About Wordtune

Wordtune is an AI writing assistant developed by AI21 Labs, an Israeli AI company founded in 2017 by AI pioneers including Prof. Amnon Shashua. The tool offers sentence-level rewriting with options to adjust tone (casual or formal), shorten or expand text, and translate from other languages into English while rewriting. Wordtune is available as a browser extension for Chrome and Edge, integrating with Gmail, Google Docs, LinkedIn, and other web-based writing environments. The Wordtune Read feature can summarise long documents, articles, and PDFs, making it valuable for research and information-heavy work. AI21 Labs, the company behind Wordtune, is a well-funded AI research company (over $300M raised) that develops its own foundation models (Jamba). This gives Wordtune a unique advantage in model quality and customisation. The platform is used by millions of individuals and businesses for improving writing clarity and productivity. From a trust perspective, AI21 Labs is headquartered in Tel Aviv with offices in New York. Data is processed on cloud infrastructure. The platform offers a business plan with team management features. Wordtune does not use customer text for model training on paid plans.
