About this extension
SignalizeAI is an AI sales prospecting and prospect research tool. It reads a
company's website, gives you the angle to sell to them, and then keeps watching
that site and tells you when their pricing, hiring or messaging changes.
THE PROBLEM
Researching an account properly takes twenty minutes. You open their homepage,
their pricing page, their about page, their careers page. You work out what they
actually sell, who they sell it to, and which job title would care. Then you
write an email that sounds like you did all that.
Do it for forty accounts and it's a week.
So most people don't. They send the generic one, and it reads generic, and it
gets ignored. Or they paste a homepage into a chat window, get back a summary
that could describe any company in the category, and send that instead.
And the accounts you researched in March are wrong by June. Companies change
their pricing, their positioning, and who they're hiring, and nothing tells you.
The best moment to reach out is right after something changes, and that is
exactly the moment you find out about last, if at all.
WHAT SIGNALIZEAI DOES
Open the side panel on any company's site. In a few seconds you get a brief:
No prompt to write. No tabs to switch between. No pasting.
From the brief, one click drafts outreach emails, and follow-ups for when the
first one doesn't land. They're written from that company's specifics, not from
a template with the name swapped in.
NEW IN 5.5: CHANGE DETECTION
This is the part a chat assistant cannot do.
Save an account, turn on Watch, and SignalizeAI re-reads that site on a
schedule. When something moves, you get an alert with four things:
That last one is the whole point. Instead of "just checking in", you send
"saw you moved enterprise onto usage-based pricing", on the day it happened.
The checks run in the background on a schedule. You don't need the tab open,
the browser focused, or to remember to look. Open the panel and the changes are
waiting, newest first, grouped by Today, Yesterday, This week and Earlier.
Every watched account also keeps a history, so you can see how a company has
moved over time rather than only what changed last night.
WORKING A LIST
Batch mode takes a list of companies and works through the whole thing, so
forty accounts is one action instead of forty.
Saved prospects give you somewhere to keep them:
WHAT PEOPLE USE IT FOR
WHO THIS IS FOR
WHAT IT ISN'T
It isn't a scraper, and it isn't a contact database. It doesn't find you email
addresses or phone numbers. It reads public web pages, the ones you would read
yourself, and tells you what is on them and what changed.
It doesn't auto-send anything. Every email is drafted for you to read, edit and
send yourself, from your own inbox.
PRIVACY
We don't sell your data and we don't share it with advertisers.
The extension reads the page you're on when you ask it to, and the accounts you
explicitly save and choose to watch. It doesn't read your browsing in the
background, and it doesn't touch pages you haven't pointed it at.

watch list follow you.

WHAT SIGNALIZEAI DOES
Open the side panel on any company's site. In a few seconds you get a brief:
- What they do, in one line
- A company overview
- Their value proposition
- Their target customer
- The best persona to contact, meaning the actual job title
- A sales readiness score, 0 to 100
- A recommended outreach goal, and the angle to take
No prompt to write. No tabs to switch between. No pasting.

NEW IN 5.5: CHANGE DETECTION
This is the part a chat assistant cannot do.
Save an account, turn on Watch, and SignalizeAI re-reads that site on a
schedule. When something moves, you get an alert with four things:
- What kind of change it was: Pricing, Hiring, Messaging, or a New page
- Whether it's major or minor, so a rewritten headline doesn't shout as loudly
as a new enterprise tier - The before and the after, side by side, so you see exactly what changed
rather than a claim that something did - An opener written from that specific change
That last one is the whole point. Instead of "just checking in", you send
"saw you moved enterprise onto usage-based pricing", on the day it happened.
The checks run in the background on a schedule. You don't need the tab open,
the browser focused, or to remember to look. Open the panel and the changes are
waiting, newest first, grouped by Today, Yesterday, This week and Earlier.
Every watched account also keeps a history, so you can see how a company has
moved over time rather than only what changed last night.
WORKING A LIST
Batch mode takes a list of companies and works through the whole thing, so
forty accounts is one action instead of forty.
Saved prospects give you somewhere to keep them:
- Status tracking: Not contacted, Contacted, Follow-up due
- Search across everything you've saved
- Filters by readiness score range, by persona, and by status
- Export to CSV or Excel, so it goes into your CRM instead of living here
WHAT PEOPLE USE IT FOR
- B2B sales research before a cold email or a first call
- Account research on a named-account list, kept current instead of going stale
- Website change monitoring on the accounts that matter, rather than every page
- Competitor monitoring: watch a competitor's pricing page and messaging the
same way you watch a prospect - Lead research and qualification on inbound, before you spend a call on it
WHO THIS IS FOR
- Founders doing their own sales, who don't have a research team
- SDRs and AEs working a named-account list they need to stay current on
- Agencies and consultants qualifying inbound before the first call
- Anyone who has to know a company before they contact them
WHAT IT ISN'T
