Gmail handles email well on its own, but it does not check your writing, record video replies or pull tasks out of a thread. Chrome extensions fill those gaps directly inside the compose window, so you do not need to copy text elsewhere or switch tabs to get the job done.

Fix grammar and tone before sending

Grammarly and LanguageTool both check spelling, grammar and tone inline as you write a Gmail message, underlining issues and suggesting fixes. Grammarly's free plan covers core grammar checks, while LanguageTool supports more languages, which matters if you write emails in more than English.

Record a screen reply instead of typing

Loom records your screen and camera, then drops a shareable link straight into your Gmail draft, useful for explaining a bug, walking through a document or giving feedback that is easier to show than describe. The free plan covers occasional use; heavier recording volume needs a paid plan.

Find contacts and manage tasks from your inbox

Apollo.io surfaces email addresses and phone numbers while you browse LinkedIn, which pairs with Gmail for outreach. Todoist lets you turn any email into a task with a due date without leaving the inbox, so follow-ups do not get lost in an already full Gmail account.

Best Chrome extensions for Gmail: FAQs

What is the best Chrome extension for Gmail?

Grammarly is the most widely used Gmail extension because it checks grammar and tone directly in the compose window with a solid free tier. The best choice still depends on whether you need writing help, video replies or contact finding.

Is there a dictation extension for Gmail?

Several speech-to-text extensions can dictate text into any web form, including Gmail's compose window, though accuracy varies by extension and microphone quality. Check reviews for Gmail-specific compatibility before relying on one for important emails.

Can I use ChatGPT inside Gmail with an extension?

Some browser extensions add an AI writing assistant panel to Gmail's compose window for drafting or rewriting replies. Review what email content the extension can read before granting Gmail access, since this varies by extension.

Is Grammarly safe to use with Gmail?

Grammarly is a widely used, established extension that scans your typed text to offer suggestions. Read its permissions and privacy policy if you send sensitive information by email, since it needs access to what you write to function.

Does Loom work inside Gmail?

Yes. Loom's extension lets you record your screen or camera and automatically inserts a shareable link into your Gmail draft, so the recipient can watch the video without downloading a file.

Are Gmail extensions free?

Most popular Gmail extensions, including Grammarly, LanguageTool and Todoist, offer a free plan with core features and a paid plan for advanced usage or higher limits. Check each extension's current plans before installing.

Can I turn a Gmail email into a task?

Yes. Todoist's extension adds a button to Gmail that creates a task from the open email, including a link back to the original message, so follow-ups stay organized outside your inbox.

Do Gmail extensions work on the mobile Gmail app?

No. Chrome extensions only run in the desktop Chrome browser, so any Gmail extension you install will not appear in the Gmail app on Android or iOS.

Do Gmail extensions work in Edge and Brave?

Most Gmail-focused extensions from the Chrome Web Store, including Grammarly and Loom, also install in Chromium-based browsers such as Microsoft Edge and Brave.

Will a Gmail extension slow down my inbox?

A well-built extension adds minimal delay, but running several inbox-scanning extensions at once can slow Gmail's loading. Disable ones you rarely use rather than keeping every extension active.

Is Apollo.io useful for Gmail users?

Apollo.io mainly finds contact details while browsing LinkedIn rather than inside Gmail itself, but it suits Gmail users doing outreach, since you can email the contacts it finds directly from your inbox.
