## Overview

HelloDexter is a Chrome extension built for sales teams, recruiters and founders who work out of LinkedIn all day. Instead of juggling separate prospecting tabs, it layers contact details directly on top of the LinkedIn interface: when you open a profile you can surface a verified email address, a phone number and social handles, then save the person into your own lead list in the HelloDexter dashboard.

The extension also handles volume work. With a single click it can scrape multiple profiles from a search results or people page and push them into your pipeline, which is useful when you are building a list of a hundred prospects rather than five. An AI writing layer then generates personalized opening messages and follow-ups based on the profile context, so outreach goes out while you are still inside the same tab.

The tool was previously distributed under the name Cerebria, and the Chrome Web Store listing now serves the HelloDexter brand. It stores personally identifiable and authentication information, which the developer states is not sold to third parties. Because it is an independent third-party extension rather than an official LinkedIn product, you should check current data policies and account-safety guidance before scaling any automation.

## Pricing & Plans

Pricing is not published on the extension listing. The original directory entry listed it as contact-for-pricing, so the practical route is to install the extension or reach the vendor through its sales channel for current plan details. No specific price should be assumed.

## Key Features & Capabilities

- **Inline contact enrichment:** Surface email addresses, phone numbers and social profiles for the LinkedIn contacts you are already viewing, without switching tools or tabs.
- **One-click multi-lead extraction:** Pull multiple profiles from a people or search results page in a single action and push them straight into your saved lead list.
- **AI-personalized outreach:** Generate tailored opening messages and follow-ups from profile context so first-touch emails feel researched rather than templated.
- **LinkedIn-native workflow:** Everything runs inside the LinkedIn interface, keeping prospecting, enrichment and messaging in one continuous flow.
- **Central lead storage:** Valuable contacts are saved to your HelloDexter account so lists survive across sessions and devices.

## Primary Use Cases

- **Build a qualified prospect list fast (Sales development rep):** Work through LinkedIn search results, enrich each profile with email and phone data, and export a ready-to-contact list in one sitting.
- **Run lean outbound without a data team (Founder or agency owner):** Enrich and message prospects directly from your own browser instead of paying for a separate contact database seat.
- **Reach candidates off-platform (Recruiter):** Pull email and phone details for shortlisted candidates so you can follow up outside LinkedIn messaging limits.
- **Personalize at scale (Account executive):** Draft AI-assisted first-touch notes that reference each prospect's profile, then follow up without leaving the tab.

## Strengths

- Enrichment, extraction and AI messaging live in a single LinkedIn-side extension
- Multi-profile extraction saves significant time on list building
- AI-assisted personalization keeps outreach from feeling copy-pasted
- Lightweight footprint with a small, focused feature set

## Limitations

- Pricing is not published, so cost must be confirmed with the vendor
- Small user base and modest review volume, so social proof is limited
- As a third-party LinkedIn automation tool, usage carries account-safety considerations
