Grammarly alternatives for proofreading and rewrites

Lexicon provides a dedicated proofreading editor with LanguageTool grammar and spelling corrections, a personal dictionary and accept-or-dismiss controls. Optional local AI handles shortening and tone changes. It suits reviewing a draft closely rather than adding an assistant to every app.

Kerlig covers spelling, grammar and sentence revision inside the Mac apps where you already write. Global hotkeys and saved actions suit recurring email or message edits; local models or your chosen cloud provider supply the writing assistance.

Witsy applies custom AI commands to highlighted text in other applications and offers a scratchpad for drafts. Choose it for rewriting across desktop apps with Ollama, LM Studio or a cloud model, rather than a fixed grammar-checking engine.

Private LLM provides Mac writing actions for selected text in other apps. Rewrite a passage, summarize it or request corrections without moving it into a separate document editor; supported writing languages depend on the app.

ThunderAI brings proofreading and tone changes into Thunderbird emails. A side-by-side picker lets you accept individual corrections, while rewrites preserve the message's HTML formatting. It works inside Thunderbird rather than across every writing app.

NativeMind helps with browser writing through proofreading, tone changes and text rewrites. It can also draft Gmail replies using the local model connected through Ollama, alongside its webpage and document tools.

ONLYOFFICE Docs brings grammar checks and rewriting into document and PDF editors through its AI plugin. Teams can discuss revisions with comments and tracked changes; the plugin must be activated and connected to a model.

BoltAI brings inline text editing and a shortcut overlay to Mac writing tasks. Reusable prompts and model comparisons suit revisions that need context or a particular voice; it covers AI editing rather than continuous rule-based grammar alerts.

Obsidian Local GPT corrects spelling and grammar or continues a draft inside an Obsidian note. Selected text, linked notes and PDFs can supply context, with custom prompts for the writing actions you repeat.

IntelliBar suits proofreading and writing edits through a Mac shortcut-driven assistant. Saved instructions let you reuse an editing request, and side-by-side model replies help you compare revisions.

Raycast Ollama corrects grammar in selected text or clipboard content through desktop commands. You can save custom editing prompts with a chosen model; the extension requires Raycast and an Ollama connection.
