What is Email Whisperer?

Email Whisperer is an email polishing tool. A Chrome extension that writes, rephrases, spell checks and fixes emails inside Gmail and Outlook, with tone presets, custom prompts and an assistant that can be trained on your own documents and writing style.

Email Whisperer is an AI email writer delivered as a Chrome extension that plugs directly into Gmail and Outlook. Rather than asking users to draft in a separate tab and paste the result back, the tool sits inside the compose window and generates, rephrases, spell checks and corrects messages where they are actually written. Compose, reply and follow-up emails are all covered, and the generator can be steered with a chosen tone, a target length and custom prompts. A rewrite action lets a user select any part of a draft and have it reworked without regenerating the whole message. Practical use revolves around tone and personalization. A default tone can be saved so frequent senders do not reselect it on every email, and more than ten tone presets cover formal business correspondence through to casual notes. On the paid tier the assistant, referred to as Addy, can be trained on website content or PDF files so it understands a business, and it can also be trained to imitate the user's own writing style. The Unlimited plan adds suggested replies and the ability to summarize emails and attachments, which suits people clearing long threads rather than only writing new ones. Who it fits: sales and customer-facing staff who write high volumes of similar mail, founders and freelancers handling correspondence across several relationships, and anyone who wants a grammatically clean draft without leaving the inbox. The Business tier targets teams that want a shared knowledge base and a model tuned to their brand voice, with background generation and early access to new features. Where it sits among alternatives: general writing assistants such as ChatGPT require switching context and copying text, while Email Whisperer is narrow but embedded. The trade-off is a smaller feature surface and a browser-extension dependency. The free tier runs on GPT 3.5 with three emails per day, and the paid tier moves to GPT-4 with unlimited daily emails and support for major languages.

How do you use Email Whisperer?

  1. 1Add the extension to your browser
    Install Email Whisperer from the Chrome Web Store. The same listing serves both Gmail and Outlook, so a single install covers either inbox.
  2. 2Open a compose window in Gmail or Outlook
    Start a new email or hit reply in the web interface. The extension activates alongside the compose field where the writing happens.
  3. 3Pick a tone or save a default
    Choose from the available tone presets for the message at hand, or set your usual tone as the default so it is preselected next time.
  4. 4Generate, then adjust length and prompt
    Generate the draft, then use the length control and a custom prompt to push the output toward the detail or brevity you need.
  5. 5Rewrite or spell check selected text
    Highlight any sentence you are unhappy with and use the rewrite action to rework just that portion, then run the spell check before sending.
  6. 6Train the assistant on your own material
    On a paid plan, upload website pages or PDFs so the assistant understands your business, and let it learn your writing style for personalized drafts.
