About this extension
ToneClone is an AI writing assistant that sounds like you, not like AI. Build a persona from your own writing samples, then draft and rewrite emails, posts, and messages in your voice.
Keep one consistent voice as you move between supported writing tools. Instead of starting every draft from scratch or switching between ChatGPT and your inbox, bring your voice, instructions, and relevant context into the places you already write.
WRITE IN YOUR VOICE
- Create a persona from text, files, or URLs containing your writing samples.
- Use examples of your emails, blog posts, or other writing to guide vocabulary, sentence style, and tone.
- Switch between personas for work, personal messages, social media, or clients, within your plan's limits.
DRAFT, REWRITE, AND REFINE
- Write an email reply, a LinkedIn post, a support response, or a longer draft in the writing sidebar.
- Use inline writing controls in supported text fields, or copy a sidebar draft into another editor.
- Make a draft shorter, longer, more casual, or more professional with quick actions.
- Watch responses appear as they are generated.
- Reuse prompts with prompt history and revisit earlier sidebar draft versions.
- Configure keyboard shortcuts and turn individual integrations on or off in Settings.
ADD THE CONTEXT YOUR WRITING NEEDS
Knowledge Cards hold details you reuse: project background, company information, product facts, or contact details. Include relevant cards when drafting instead of retyping the same information.
Context extractors can bring selected text, page content, or supported conversation context into a request. Email integrations provide thread context for replies and summaries. Availability depends on the site and the content accessible to the extension.
EMAIL, SOCIAL POSTS, MESSAGES, AND DOCUMENTS
- Gmail and Outlook: compose emails, draft replies with thread context, and summarize conversations.
- LinkedIn: draft posts and messages, with conversation extractors for supported message threads.
- X (Twitter): draft posts and replies in your voice.
- Slack and Google Voice: draft responses with available conversation context.
- GitHub: write pull request descriptions, documentation, and comments.
- Google Docs: use the sidebar to draft and refine, then copy your text into the document.
For other websites, including community forums, help desks, and project tools, use supported text fields or the sidebar copy workflow. Site layouts, browser restrictions, and editor types affect which controls and context are available.
USE IT FOR YOUR EVERYDAY WRITING
- Founders: investor updates and outreach that read like you wrote them.
- Professionals: email replies, follow-ups, and clear work messages.
- Sales and support teams: outreach and customer responses with reusable background details.
- Content creators: blog drafts and social posts with a consistent voice.
- Social media managers: separate personas for different clients or accounts.
- Developers: documentation, PR descriptions, and technical explanations.
