Wordtune
AI writing companion that rewrites, expands, and summarises your writing — understanding context, not just words.
Overview
Wordtune is an AI writing tool developed by AI21 Labs that focuses on improving and refining existing writing rather than generating from scratch. Its core Rewrite feature can rephrase any selected text while preserving its meaning, suggesting multiple alternative formulations to choose from. This 'suggest and choose' model gives writers control that pure AI generation tools lack.
The Casual and Formal tone options rewrite text to match the desired register — a formal email can be instantly made more conversational, or vice versa. The Expand and Shorten features adjust the length of text: Expand adds context and detail to brief notes, while Shorten condenses verbose text to its essential points. The Spices feature adds specific improvements like examples, statistics, and counterarguments.
Wordtune is developed by AI21 Labs, an Israeli AI research company founded by renowned AI researchers including Yoav Goldberg. The underlying Wordtune model is a specialised text editing model rather than a general-purpose LLM, which makes it more accurate for the specific task of text refinement. The Chrome extension works across Gmail, Google Docs, and web text fields.

Use cases
ASEAN Perspective
Wordtune in Southeast Asia
ASEAN-region availability and pricing notes coming soon. Drop the editorial team a note via /contact/ if you can supply local context (Singapore/Malaysia/Indonesia/Thailand/Vietnam).
Wordtune is an AI writing assistant focused on rewriting, rephrasing and tone adjustment rather than generating content from scratch. Its suggestions feel natural and context-aware, and the browser/app integrations make it a genuinely useful daily aid, especially for non-native English speakers polishing tone and clarity. The free tier is usable for light editing.
It is narrower than all-in-one writing suites and its standout rewriting niche has been increasingly absorbed by general chat assistants. The free tier caps rewrites quickly, and there is no consumer API. ASEAN users get standard global English support but limited regional-language depth. A strong pick for clarity-focused editing and ESL writers; less compelling if you already use a capable general LLM.
