The InstaText browser extension brings advanced editing directly into your everyday workflow. Whether you’re writing an email in Gmail, editing a document in Google Docs or Overleaf, chatting on Slack, or posting on LinkedIn, InstaText helps you improve your writing in real time – without copying and pasting text into a separate app. 

Designed to make professional writing effortless, InstaText goes beyond grammar and spell check to enhance clarity, readability, and flow across more than 20 platforms through its browser extension, helping you stay focused on your message.

And because InstaText doesn’t use generative AI, your originality and authorship remain fully intact, making it ideal for contexts where AI-generated content is not preferred, is restricted, or is prohibited, such as academic writing. 

Seamless, real-time editing

Once installed, the browser extension integrates automatically into supported apps and platforms.

To use it:

• Select the text you want to improve.
  
• Click the InstaText button that appears next to your selection, or
  
• Use the shortcut Ctrl+D (Windows) or Cmd+D (Mac) to open the Editor instantly.

The InstaText Editor opens beside your text and immediately suggests improvements you can review. You can accept or reject the suggestions individually or all at once. 

This saves time, reduces distractions, and makes high-quality editing available whenever and wherever you need it – while also helping you strengthen your writing and cognitive skills over time.

Works where you write

InstaText is compatible with a wide range of online platforms, offering full editing functionality across more than 20 commonly used applications. This includes email tools like Gmail and Outlook Web, collaboration platforms such as Google Docs, Overleaf, and Notion, and social or professional networks like LinkedIn, X, and Facebook.

This broad integration means that no matter where you communicate or create content, InstaText can help you make your writing more effective – from academic papers and business correspondence to marketing posts and everyday messages.

Customisation for your writing context

Every writer has a different purpose, audience, and writing style. The InstaText browser extension adapts to all of them through its advanced customisation features.

Dialect settings

Choose between British and American English. InstaText automatically adjusts spelling, grammar, and vocabulary to match your selected dialect.

Formality adjustment

Fine-tune the tone of your text by selecting formal, informal, or auto mode.

• Formal tone suits academic, business, or professional writing.
• Informal tone makes your messages sound more natural and conversational.

Personal Dictionary

Add your own terms, names, and expressions – whether individual words or word combinations – to keep them unchanged. This ensures accuracy and consistency for technical terminology, brand names, and key phrases unique to your field or style.

Together, these features make your writing not only correct, but also contextually appropriate and true to your personal or professional voice.

“I am a translator and proofreader by profession and have tried many editing tools. It’s not an exaggeration to say that all the other apps I’ve used so far don’t come close to InstaText. It is literally innovative and revolutionary and has taken the editing game to a new level, leaving other competitors in the dust.”

— Dr. Ghodrat Hassani, Researcher in Translation Studies

Editing beyond English

InstaText’s capabilities extend well beyond English, our flagship and most advanced service. The browser extension supports editing in a growing number of languages, including Spanish, French, German, Italian, and Portuguese. 

You can easily switch between languages using the dropdown menu in the Editor or directly in the browser extension.

No matter the language you choose, InstaText enhances clarity, sentence structure, and readability while keeping your tone and meaning intact. The same technology that powers English editing is applied across all supported languages, helping professionals, academics, and everyday writers express themselves confidently in their native or preferred language.

Non-English editing is included in the InstaText One plan at no additional cost, offering subscribers unlimited access.

Privacy and control

InstaText was built with user privacy at its core. The browser extension never stores or shares your text. It only processes the content you actively select for improvement and does not interfere with your writing until you request assistance.

You have full control at every stage – from choosing when to activate InstaText to deciding which edits to apply.
