InstaText vs LanguageTool

InstaText improves writing supplied by the user for clarity, readability, grammar, and style without generating new content. Suggestions remain visible for users to accept or reject, and edits are not applied automatically. The service runs on the web and through a browser extension supporting more than 20 platforms, including Google Docs, Gmail, WhatsApp, Slack, Overleaf, Outlook, Salesforce, and WordPress. A Word add-in works with Word online and the classic version, with Track Changes for suggested revisions. Tone controls offer Auto, Formal, and Informal settings, while Personal Dictionary rules can preserve or replace specified wording. The Free plan costs nothing, allows five improvements daily and up to 1,500 characters at once, and is for personal, non-commercial use. InstaText One costs €24.99 a month billed monthly or €9.99 a month billed yearly at 119.88 € yearly, with unlimited use. The Windows desktop app is early access and requires internet; macOS is coming soon.

LanguageTool is a writing assistant that checks grammar, spelling, punctuation, casing, and style across 31 languages. It also offers tone detection, writing statistics, and paraphrasing modes for making sentences more formal, fluent, simple, or concise. The service works through browser extensions and Windows, macOS, and iOS apps, and integrates with Google Docs, Microsoft Word, Apple Pages, and LibreOffice. Email add-ons are available for Gmail, Outlook, Apple Mail, and Thunderbird. The free version covers spelling, simple punctuation, and some style issues, with a 2,000-character limit per text field; Premium allows up to 150,000 characters. Individual Premium can be billed monthly, quarterly, annually, or every two years, but no plan prices are listed. Text written through the browser add-on is usually not saved; text in the editor is stored and accessible across devices. Teams can manage invited users and share style guides and dictionaries. Business solutions are described as GDPR-conform and support consistent brand voice. Premium has a 14-day money-back guarantee with cancellation and refund without questions.
