Wordtune

What is Wordtune?

Wordtune is an AI-powered writing and reading assistant developed by AI21 Labs that helps users refine, paraphrase, and improve their text. It works primarily at the sentence and paragraph level with rewriting options, grammar correction, tone adjustments, and summarization capabilities built on machine learning and natural language processing. The tool targets writers, students, professionals, and non-native English speakers who want to polish existing drafts rather than generate content from scratch. What sets it apart from general-purpose AI tools is its focus on preserving the user's original meaning while offering controlled, contextual suggestions that match their writing style and tone.

Key Features

• Paraphrasing and Rewriting: Provides multiple alternative versions of a selected sentence or paragraph, with options to shorten, expand, or creatively rephrase while keeping the original meaning intact.
• Grammar and Tone Adjustments: Fixes spelling and grammar errors, refines sentence structure, and switches between casual, formal, professional, friendly, or persuasive tones for different audiences and contexts.
• Spices (Generative Toolkit): A co-writing feature that adds supporting material such as examples, analogies, counterarguments, statistics, or historical context to help users expand ideas and overcome writer's block.
• Summarization via Wordtune Read: Condenses long documents, PDFs, articles, webpages, and YouTube videos into key points, with executive summaries, hyperlinked citations, and keyword search support.
• Smart Synonyms and Style Edits: Context-aware synonym suggestions alongside grammar and spelling corrections, aimed at improving the overall flow and readability of a piece.
• Continue Writing: Generates contextual suggestions to help users add examples, summaries, or conclusions to their existing text (limited to 10 uses per day on the free plan).
• Ask AI: Available on premium plans, this feature generates ideas or answers questions to support the writing process directly within the editor.

• Regulated industry professionals managing content compliance: Legal, medical, finance, and insurance professionals apply Wordtune with guardrails that include compliance checks for claims verification, scope management, and disclosure requirements.
