Learns from your real writing

AI emails that sound like you.

Not a template. Not generic. ColdCheck learns your voice from a few samples of your real writing, then drafts messages that match how you actually write.

How it works

Set up once. Use it forever.

No prompting tricks. No templates. Just describe what you need and get a draft in your voice.

01TEACH

Paste a few emails you've written

3 to 5 real messages you've actually sent. ColdCheck learns your rhythm, vocabulary, and tone. It doesn't store the content. Just the patterns.

02DESCRIBE

Say what you need

No prompts to craft. "Follow up with Mike on the proposal" or "Tell my client I'll be late." Describe the situation, not the email.

03SEND IT

Get a draft in your voice

Review it, tweak if you want, then send. It sounds like you because it learned from you, not from a million other people's emails.

Chrome extension

Write inside Gmail.
Never leave your inbox.

The ColdCheck extension lives inside Gmail, Outlook, and LinkedIn. Open it, describe what you need, insert the draft. No tab switching. No copy-pasting.

Quick-edit buttons let you adjust tone instantly. Shorter, more professional, friendlier. No regenerating from scratch.

  • LinkedIn messages & posts
  • One-click insert into compose window
  • Adjust tone instantly without regenerating

Hey Jake,

Really enjoyed our conversation at the summit. The direction you're taking Meridian is exactly the kind of thing I've been thinking about lately.

Would you be up for a quick 20-minute call sometime next week? Think there could be some interesting overlap worth exploring.

Gets smarter over time

The more you use it, the less you fix it.

Every edit you make before sending teaches ColdCheck your actual preferences. It learns.

Every other AI tool

Same output. Every time.

ChatGPT doesn't remember that you hate exclamation points. Or that you always sign off with just your first name. Or that you write in short punchy paragraphs.

You fix the same things on every draft. It never learns. You're doing all the work.

  • ×Starts from zero every session
  • ×Doesn't know your preferences
  • ×Generic output regardless of who you are
  • ×You adapt to the tool
ColdCheck

Tracks what you actually change.

When you edit a draft before sending, ColdCheck notes what changed: what you removed, added, rewrote. Over time it stops making those mistakes.

The drafts get closer to send-ready. Your fingerprint sharpens. You do less work.

  • Learns from every edit you make
  • Remembers preferences across sessions
  • Drafts improve the longer you use it
  • The tool adapts to you

Why not just use ChatGPT?

Good question. Honest answer.

ChatGPT is a great tool. It's just not built for this specific problem.
