ColdKnock

Select job description in your browser, send them to AI, generate personalized emails using templates and bulk-send with one click

ColdKnock turns every job board, career page, and client site into a direct outreach pipeline. Stop copy-pasting job descriptions into spreadsheets, digging for recruiter emails, and manually rewriting cold emails one by one. With ColdKnock, you capture leads directly from your browser, normalize the job requirements with AI, match them to your tailored resumes and templates, and batch-send personalized emails straight from your own Gmail account. Whether you are hunting for your next engineering role, pitching freelance services, or running targeted outreach, ColdKnock handles the busywork so you can focus on conversations. What is ColdKnock? ColdKnock is a complete outbound workflow platform consisting of: The Chrome Extension (This tool): A lightweight, keyboard-first in-page capture overlay that extracts job descriptions, recruiter contact emails, and page metadata in one click. The Web Dashboard: A centralized workspace where your captures are structured, matched against your resume variants, transformed into customized cold emails, and scheduled for batch dispatch. The Backend Intelligence Engine: Secure AI-driven schema extraction, document parsing, and rate-limited Gmail API sending. Key Features of the Extension 1. Instant Capture via Keyboard Shortcut (Alt + K or Cmd + Shift + K) No clicking through endless browser menus. Find an interesting job posting or freelance brief, highlight the relevant text, press your shortcut, and the ColdKnock review card slides into view instantly. 2. Dual Capture Modes: Precision Selection & Full-Page Fallback Selection Mode (Recommended): Highlight the exact job description or requirements list. The extension captures only the relevant text, keeping the signal high and eliminating surrounding page noise. Full-Page Capture: Browsing on mobile or can't easily select text? Trigger the hotkey with nothing highlighted, and ColdKnock performs an intelligent full-page extraction with built-in cleanup of navigation, scripts, and footers. 3. Automatic Recruiter Email Detection with Provenance Tracking Never lose track of where an email came from: The extension automatically scans the selected text and active page for hiring team emails and mailto: links, filtering out generic corporate addresses (like support@ or privacy@). Provenance Badging: When an email is found automatically, it is labeled as extracted. If you type or edit it manually, ColdKnock transparently marks it as user-provided, ensuring data integrity in your dashboard. If no email is detected, an optional input field lets you enter one on the fly. 4. Multi-Profile Switching Manage multiple outreach tracks without separate accounts: Job Seeking: Target hiring managers, recruiters, and team leads with role-specific resumes and application templates. Freelancing Pitches: Target prospective clients with project-based proposals, portfolio links, and scope estimates. Switch between profiles directly from the capture card before saving. 5. Zero-Interference Shadow DOM Interface The ColdKnock extension UI renders inside an isolated Shadow DOM container. It never clashes with host website styles, breaks site layouts, or lets invasive third-party CSS compromise your extension experience. 6. Resilient & Crash-Proof Network drop? API hiccup? Your captured text, edits, and emails are never discarded until the server confirms a successful save. You can retry immediately without losing your input. How the Complete Workflow Works Capture: Highlight a job posting on LinkedIn, Greenhouse, Lever, Indeed, or any company careers page and press Alt + K (or Cmd + Shift + K). Review & Save: Confirm the recruiter email, select your target profile (Job Seeking or Freelance), and hit Save. AI Normalization: ColdKnock’s backend ingests the raw capture, extracts key requirements, tech stacks, and company background, and transforms it into a clean, canonical listing. Template & Resume Matching: In your web dashboard, ColdKnock matches the listing against your uploaded resumes (e.g., Frontend, Backend, Full Stack) and recommends the best-fit template. Batch Review & Send: Review all populated variables ({{recruiter_name}}, {{company}}, {{custom_hook}}), select the leads you want to contact, and send them in batch through your own Gmail account with built-in pacing to protect inbox deliverability. Privacy, Security & Google API Compliance ColdKnock is designed with privacy as a foundational principle: User-Initiated Capture Only: The extension never monitors your browsing history, tracks page visits, or silently captures data in the background. Content is read only when you explicitly press the capture shortcut. Transient In-Browser State: Raw page contents and temporary edits live strictly in volatile browser memory. They are never stored unencrypted in local browser storage. Google API Compliance: ColdKnock adheres strictly to the Google API Services User Data Policy, including Limited Use requirements. Your Gmail data is used solely to dispatch outbound emails that you have explicitly reviewed and approved. We never sell your data, share it with advertisers, or use your private communications to train public AI models. No Site-Specific Scraping: ColdKnock doesn't inject brittle scrapers or tamper with host websites. System Requirements & Permissions ActiveTab & Scripting: Required to read the highlighted text, page title, and URL only when you trigger the hotkey. Storage: Used solely to persist your default outreach profile and extension settings. Host Permissions: Restricted to communicating securely with the ColdKnock ingestion API ([https://api.coldknock.com](https://api.coldknock.com)). Take Control of Your Outreach Whether you are sending 5 targeted applications a week or managing a multi-client freelance pipeline, ColdKnock eliminates manual overhead and brings speed, structure, and intelligence to your cold outreach. Install the ColdKnock extension, connect your dashboard, and start reaching out with confidence.
