PeopleDB is a Chrome add-on designed to enrich LinkedIn profiles by providing email addresses, phone numbers, and social media links directly within the browser. This tool simplifies the process of gathering contact information by displaying a small icon on the right side of the screen when a LinkedIn profile is accessed. Users can click the icon to retrieve aggregated contact data from various sources, ensuring the results are verified and deduplicated for accuracy.

The extension is optimized for speed, caching results locally after the first lookup for instant access during subsequent visits to the same profile. PeopleDB requires users to create an account and obtain an API key, which allows for 10 free credits upon registration. The pricing model is straightforward, charging only for successful lookups, with no expiration on credits and no recurring fees, making it a flexible option for users needing reliable contact enrichment.
