Best Grammarly Alternatives in 2026: 6 Tools Compared

Grammarly popularized the idea of an always-on writing checker, but the category has split into several different kinds of tools since then: grammar checkers, paraphrasers, general AI assistants, and AI-powered keyboards. Which one is the right Grammarly alternative depends on what you actually write and where you write it. Here are six worth knowing about.

1. QKeyboard — best for on-keyboard rewriting across every iPhone app

QKeyboard is a custom iOS keyboard that rewrites text inline, wherever you are typing — Messages, Mail, Notes, Slack, and more — without switching apps or copying text elsewhere. It offers tone presets (Professional, Concise, Urgent, Direct, Friendly) plus custom modes and BYOK support for your own OpenAI, Claude, or Gemini-compatible key. Free plan: 20 rewrites/day (100/day with BYOK). Pro is $1.49/mo, $9.99/yr, or a one-time $9.99 Lifetime option, and removes daily caps while unlocking every mode.

2. Grammarly — best for real-time grammar and tone checking

Grammarly remains the most established option for catching spelling and grammar mistakes as you type, with a tone detector that flags how a message is likely to come across. Its free tier covers the basics; Grammarly Premium (roughly $12+/mo billed annually, per Grammarly's own public pricing) adds more advanced suggestions and a broader style checker. Best suited to people whose main need is proofreading rather than tone rewriting. See our full comparison of QKeyboard vs Grammarly Keyboard.

3. Apple Writing Tools — best for zero-setup, on-device rewrites

Built into iOS 18.1+ on iPhone 15 Pro and later, Apple Writing Tools lets you select text in any app and choose Proofread or Rewrite, with no installation or permissions required. It processes everything on-device, which is a genuine privacy advantage, but offers one rewrite style and no tone presets or custom modes. Full breakdown: QKeyboard vs Apple Writing Tools.

4. ChatGPT — best for drafting from scratch

ChatGPT is not a proofreading or keyboard tool, but its conversational format makes it strong for brainstorming, outlining, and writing longer pieces from a blank page. The tradeoff for quick edits is workflow: fixing a short message means switching apps, pasting the text and a prompt, then copying the result back. Better suited to long-form work than in-place edits — see QKeyboard vs copy-pasting into ChatGPT for a workflow-speed comparison.

5. Quillbot — best for paraphrasing longer documents

Quillbot is a web and desktop-oriented paraphrasing tool aimed at students and writers, with modes like Standard, Fluency, and Formal, plus a grammar checker and citation generator. It shines when you have a full document open and want to reword paragraphs for variety, though its mobile presence is lighter than its browser extension. See QKeyboard vs Quillbot for more on the difference between paraphrasing and tone-preset rewriting.

6. ProWritingAid — best for deep style and structure analysis

ProWritingAid leans further into editorial analysis than Grammarly or Quillbot, with reports on sentence length variation, overused words, pacing, and readability, aimed at fiction and long-form nonfiction writers. It is a desktop and browser-extension tool rather than a mobile keyboard, so it fits a dedicated editing session better than a quick message on your phone. Best suited to writers revising a manuscript or a lengthy draft rather than daily messaging.

Picking one

There is no single best tool across all six — the right pick depends on the writing you actually do most. If most of your writing is short messages typed on your phone throughout the day, an inline keyboard tool like QKeyboard removes the most friction. If you are revising a long document at a desk, a paraphraser or style analyzer fits that session better. Several of these tools are free to try, so it is reasonable to keep more than one installed and use whichever fits the writing in front of you.
