ColdCheck: Writing That Sounds Like You

Generate emails, LinkedIn messages, and LinkedIn posts that sound like you, not like AI. Works inside Gmail, Outlook, and LinkedIn.

ColdCheck learns how you write and generates messages that match your voice so you can skip the blank screen and send drafts that actually sound like you. HOW IT WORKS Train your voice: Provide a few examples of emails you've written. ColdCheck analyzes your style: sentence length, tone, vocabulary, and creates a writing fingerprint. Describe what you need: Open the side panel on Gmail, Outlook, or LinkedIn. Tell ColdCheck what you want to say in plain language. Get a draft in seconds: ColdCheck generates a message in your voice. Insert it directly into your compose window, or copy and paste. FEATURES Works where you write: Side panel opens alongside Gmail, Outlook, and LinkedIn. No tab switching. Smart reply detection: Automatically reads email threads and suggests quick reply options. Refine in one click: Make drafts shorter, more professional, friendlier, or clearer. Edit inline: Tweak any draft directly in the side panel before inserting. LinkedIn posts: Generate LinkedIn feed posts in your voice, with ideal length guidance. Learns as you go: Every edit and approved draft improves future suggestions. PRIVACY 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.
