ColdCheck Chrome Extension: Write in Your Voice Right Where You Work

You're writing an email. You switch to ColdCheck. You describe what you need. You copy the draft back. You switch tabs again.

Sound familiar?

We built ColdCheck to save you time. But tab-switching was eating into that. So we built something better.

Introducing the ColdCheck Chrome Extension

The ColdCheck Chrome extension brings your AI writing assistant right into the apps you use every day. No more tab switching. No more copy-paste gymnastics. Just describe what you want to say, and get a draft in your voice. No need to leave Gmail, Outlook, or LinkedIn.

How It Works

1. Train your voice (once)
Sign up at app.coldcheck.ai, add a few writing samples, and ColdCheck learns how you write: sentence length, tone, vocabulary. Your writing fingerprint.

2. Open the side panel
When you're in Gmail, Outlook, or LinkedIn, click the ColdCheck icon. A side panel opens right next to your compose window.

3. Describe what you need
Tell ColdCheck what you want to say in plain language. "Follow up on my last email, keep it brief." "Introduce myself to Sarah, mention we met at the conference."

4. Get a draft in seconds
ColdCheck generates a message in your voice. Insert it directly into your compose window, or copy and paste. Edit inline if you want to tweak it.

What You Can Do With It

• Gmail & Outlook: Generate emails and replies in your voice. The extension reads email threads and suggests quick reply options.
• LinkedIn messages: Write connection requests and DMs that sound like you, not like a template.
• LinkedIn posts: Generate feed posts in your voice, with ideal length guidance.
• Refine in one click: Make drafts shorter, more professional, friendlier, or clearer.
• Edit inline: Tweak any draft directly in the side panel before inserting.

Every edit and approved draft improves future suggestions. ColdCheck learns as you go.

Privacy First

ColdCheck stores writing style patterns as numerical embeddings, not your raw text. The extension only accesses compose window content when you request a draft. No inbox access. No browsing history. No data sold to third parties.

Get Started

5 free drafts per month. No credit card required. Add the extension, sign up (or sign in if you're already a user), and start writing in your voice right where you work.

We're excited to bring ColdCheck closer to where you actually write. Let us know what you think.
