A profile on X, GitHub, Instagram, Facebook, or Crunchbase
LinkedIn is the profile people mean when they say they looked someone up. It is not the only page a person keeps. The same name shows up as a handle on X, a set of repositories on GitHub, a photograph on Instagram, an older account on Facebook, or a founder line on Crunchbase. Each of those pages is a real place you already opened. None of them is a reason to start a second search.
Extension is the Chrome side panel. On a profile, the record is read from the URL. The page stays where it is. The person sits beside it: the email, the phone, the work behind the title, the other profiles, and the rest of the record. You do not copy the address into another box. Opening the page was the query.
Why the URL is the query
A profile URL is a claim that this page is this person. A search for the name is a guess. Two people share a name. One of them changed jobs. One of them uses a short handle that is not the name on the résumé. The URL you opened already chose. Extension follows that choice. Move from one profile to the next and the panel follows the URL you are on. You are not keeping a list of lookups in your head, and you are not pasting links into a spreadsheet so a tool will consent to answer.
This is the same reading as a LinkedIn profile, which has its own note: the record beside a LinkedIn profile. The page changes. The panel does not. What changes is why you were on that site in the first place.
What each page is good for
X is often the public name. The bio is short, the handle is the thing people actually say, and the posts are a better test of whether this is the person you meant than a headline is. The record beside it is still the person, not a summary of the posts. You came to see who the handle belongs to. The email, the work, and the other profiles are the answer. The timeline can stay the timeline.
GitHub is the work you can see. A pinned repository, a company in the bio, a name that does not match the email on the commits. The profile is a good page and a bad contacts card. Extension reads the person from that URL so you do not have to decide whether the bio or the commit mail is the one you should trust before you are allowed a phone number.
Instagram is the person outside the job. It is also where a name that looks unique on a résumé turns out to be shared. A photograph and a handle settle that faster than another tab of search results. The panel is not there to describe the photographs. It is there so the person in the photograph is the same person as the work, the school, and the mail you might already have.
Facebook is often the name the résumé dropped. An older account, a city, a school listed in a place the professional profile never bothered to repeat. That is useful when you are trying to tell two people apart, and it is useful when the professional page is thin. The record beside it is the whole person, including the work the Facebook page does not know.
Crunchbase is a company-shaped page that sometimes has a person on it. A founder, an investor, a name attached to a round. The page is about the firm. The URL, when it is a person, is still a person. Extension reads that person from the URL. When the page is the company site itself, the reading changes, and that is a different note: the company on the domain.
What you get, and what it costs
The record is the person in full. Email, phone, work, education, the other places they exist. One profile does not have to carry all of that. The point of reading the URL is that you stop treating each site as a separate identity you have to reconcile by hand.
A seat opens the person. Reading a record you already have does not need another charge. Extension does not keep a browsing history in order to do this. The open page is the query. The pages around it are not a log. The plan is $49 a year. The lookup is spelled out in a lookup is one person or one company.
If the page is a mailbox, the people are the ones in the conversation you have open. If it is a calendar event, they are the people on that event. A profile URL is the case where the page has already named one person by address. That is the case this note is for.
