## HelloDexter (formerly Cerebria)

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.

- **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.

**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

## Thunderbit

Thunderbit is an agentic web scraper built for teams that need data out of websites but do not want to maintain selectors or write scraping code. It installs as a Chrome or Edge extension: open any page, click extract, and the AI reads the layout and proposes the fields that make sense — product names, prices, emails, phone numbers, listings, reviews, and more. You confirm or refine the request in plain English, and the agent returns a clean table with the rows you asked for.

For high-volume sites it offers two faster paths. Pre-built templates cover popular destinations such as Amazon, eBay, Google Maps, Zillow-style listing sites, social platforms, and directories, returning the same fields every time without consuming AI credits. Agent mode handles less structured work by following links from list pages into detail pages, pairing each result card with the information on its article or listing so research tasks that would normally take hours finish in one run. AI can also summarize, categorize, translate, or reformat data during extraction, and results export to Google Sheets, Airtable, Notion, Excel, CSV, or through the Web Scraper API.

The product is positioned mainly for sales, real estate, operations, and marketing teams. Typical uses include scraping contact information and turning directories into lead lists, tracking buying signals like hiring or funding changes, aggregating property listings, monitoring competitor prices and SKUs, watching stock availability, and gathering reviews for sentiment analysis. Pricing is freemium: a free-forever tier with limited credits, then Starter, Professional, and Business plans that scale credits and add priority support, with an API and custom enterprise terms available.

**Pricing & Plans:** Freemium. A free-forever plan provides a limited monthly credit allowance, and paid Starter, Professional, and Business plans scale credits and features (yearly billing saves around 20% with credits upfront). A Web Scraper API is available for developer integration, and Business offers custom credits, custom limits, and priority support at custom pricing.

- **One-click AI extraction:** Open a page, click extract, and AI proposes the fields worth capturing and returns structured rows — no CSS selectors or drag-and-drop setup.
- **Pre-built site templates:** For popular sites like Amazon, eBay, and Google Maps, pre-built templates return consistent fields instantly without spending AI credits.
- **Agent mode with linked pages:** Thunderbit can open linked pages and pull details from them, so a results list and its detail pages become a single table in one run.
- **AI data shaping:** Summarize, categorize, translate, reformat, or calculate fields as part of the scrape, so exports arrive ready to use.
- **Direct exports and API:** Send results directly to Google Sheets, Airtable, or Notion, export to Excel or CSV, or connect via the Web Scraper API for developer workflows.

**Strengths:** Works without CSS selectors or coding knowledge; Pre-built templates for popular sites save AI credits; Agent mode follows linked pages for deeper enrichment; Exports directly to Sheets, Airtable, Notion, Excel, and CSV

**Limitations:** Fully free usage is limited by monthly AI credits; Scraping some sites can be affected by anti-bot measures or site terms; AI field suggestions occasionally need refinement for complex or unusual page layouts; Best experience requires the Chrome/Edge extension rather than a fully browser-free workflow
