Best Alternatives to Proofly in 2025

While Proofly excels at on-device privacy, you might seek alternatives for more advanced style suggestions, integration with desktop apps, or a different pricing model. Some users may require features beyond a Chrome extension, such as support for multiple platforms or team collaboration tools.

Grammarly

It's a comprehensive cloud-based writing assistant offering advanced style, tone, and clarity suggestions, with wide integrations across browsers, desktop, and mobile, ideal for those prioritizing feature depth over strict on-device privacy.

LanguageTool

This is a strong open-source and privacy-focused alternative that supports a vast number of languages and offers both cloud and on-premise deployment options, balancing robust checking with configurability.

ProWritingAid

A powerful alternative best for long-form writers and editors, providing in-depth reports on style, readability, and overused words, though it is primarily a cloud-based desktop and web application.

Hemingway Editor

It focuses intensely on improving readability and conciseness by highlighting complex sentences and passive voice, making it a great dedicated tool for creating clear, bold copy, available as a web app or desktop software.

Microsoft Editor

A solid built-in alternative for Microsoft 365 users, offering respectable grammar and style checking directly in Word, Outlook, and browsers, with a free tier and seamless integration for the ecosystem.

The best alternative depends on your primary need: choose Grammarly or ProWritingAid for maximum writing assistance, LanguageTool for a privacy-conscious multi-language tool, or Hemingway for ruthless readability. For strict on-device privacy, Proofly remains unique.
