Zia: AI Writing Assistant from Zoho
Zia is Zoho's writing assistant that proofreads and rewrites text inside Zoho Writer, Mail, Desk, Learn, and Notebook, with a Chrome extension called BluePencil for editing anywhere on the web. It flags grammar, punctuation, spelling, and style issues in English, Spanish, and French while you type.
Most standalone grammar checkers stop at red underlines. Zia combines deep learning grammar checks, NLP preprocessing, machine learning classifiers, and 200+ rule-based style checks for bias, wordiness, vagueness, and informal phrasing. That layered stack shows up when you need more than spellcheck, such as catching subject-verb disagreement, homophone swaps, or unclear pronoun references.
Writers, support agents, students, and teams already on Zoho use Zia for everyday proofing, while Zoho Writer's broader AI features can also generate and reshape content with Zoho's LLM or a connected OpenAI key. Zoho Writer itself is free for individuals and organizations, with optional paid document automation credits when you merge data or collect e-signatures at scale.
