Grammar Checker

AI Grammar Checker With Voice Protection

Fix grammar, spelling, punctuation, and clarity — without the AI turning your writing into something generic. Written corrects your errors while keeping you sounding like you.

Why Most Grammar Checkers Fall Short for Writers

Standard grammar checkers do their job — but they often do too much. They replace your sentence rhythms, simplify your word choices, and sand down the rough edges that make your writing feel personal. Written's grammar checker takes a different approach.

With the AI Influence Slider set to Fix Only mode, Written corrects grammar, spelling, and punctuation without touching your voice. No rewriting. No paraphrasing. Just clean, accurate text — exactly as you wrote it, just fixed.

Grammar Correction for Every Type of Writing

  • Fiction and novels: Fix grammar without disrupting narrative voice, dialogue, or pacing.
  • Essays and academic writing: Correct structure, punctuation, and flow for academic clarity.
  • Business emails and documents: Ensure professional tone and correct grammar in every message.
  • Blog posts and content: Fix errors while maintaining your brand voice.
  • Social media posts: Short-form grammar correction with personality preserved.

The Difference Between Fix Only and Enhance Mode

Written gives you both options. Fix Only mode is a pure grammar and spelling correction layer — nothing else changes. Enhance mode goes one step further, improving readability and flow while still respecting your voice. Both modes let you review changes before accepting them, so you're always in control.

Grammar Checker Built for Authors, Not Businesses

Most grammar tools are built for corporate writing — clear, neutral, professional. Written was built first for authors, which means it understands that intentional comma splices, sentence fragments, and unconventional punctuation can be choices, not mistakes. The AI Influence Slider lets you decide what to fix and what to keep.
