Know when your accounts change, so you always have a reason to reach out.

Suggested opener
CopySaw you added an Enterprise tier and started hiring an Enterprise AE. Usually that means the old onboarding flow starts creaking. Worth comparing notes on how you are handling it?
Research an account once. Then keep watching it.
A one-off summary of a company goes stale the week after you read it. SignalizeAI keeps a record of how each saved account looked last time, so the next time something moves on their pricing, careers, or homepage, you have a specific reason to email instead of a generic one.
Analyze a company website
Open any public business page and run a check. You get what they do, who they sell to, and the angle to lead with.
Save it to your watch list
Saving stores the brief and a snapshot of the page, which is what makes a later comparison possible.
SignalizeAI re-checks it on a schedule
Scheduled checks run in your browser and compare each new read against the last stored one.
Reach out with the change as your reason
You see what moved on pricing, careers, or homepage messaging, with a suggested opener written from it.
Built for a named account list
Analyze one account when you are qualifying it, batch a whole list when you are building one, then watch the ones that matter.

Change detection first, research underneath it
The brief is how you start an account. Watching it is how you keep a reason to reach out every month after that.
Account change detection
Saved accounts get re-checked on a schedule. You see what moved on pricing, hiring, or homepage messaging since the last check.
Openers written from the change
Every detected change comes with a suggested first line, plus full outreach emails and follow-ups when you want them.
Sales brief on any site
Run a check on any public company page for what they do, who they sell to, the best persona, and the angle to lead with.

Questions that matter before you start
These answers focus on how change detection works, what it cannot see, plan differences, privacy, and where to go when you need help.
What does SignalizeAI scan?
Only the publicly visible text on the page you are viewing. We do not collect or send personal data or browsing history to the AI.
What does change detection actually do?
You save an account, and SignalizeAI stores a snapshot of its public pages. On a schedule it reads those pages again and compares the new read against the last one. When something moved on pricing, the careers page, the homepage message, or a new product page appeared, you get the before and after plus a suggested opener.
How fast will I hear about a change?
Checks are scheduled, not real-time, and they run inside your browser while it is open. Free checks weekly, Pro every 48 hours, Team daily. If your browser is closed for a stretch, the check happens the next time it is running. We do not send email alerts and we do not guarantee delivery of any individual check.
What will change detection miss?
Anything not visible in the public text of the pages we read. That means changes behind a login, inside images or PDFs, on sites that block automated requests, and anything that never reaches the website at all such as a funding round announced only on a news site. Small wording edits may also be reported as a messaging change when they are not meaningful.
Which plans include batch prospecting and export?
Free covers 3 watched accounts, weekly checks, and 25 saved prospects. Paid plans raise the watch limit, check more often, keep change history, and unlock batch prospecting and export.
When should I use quick website check versus batch prospecting?
Use quick website check when you want fast selling context on one account. Use batch prospecting when you need to score and prioritize a larger target list.
Do you track users or sell data?
No. SignalizeAI does not track you, run ads, or sell data. We respect privacy and only process public website content.
What gets saved in a saved prospect?
The target domain, the generated sales insights, timestamps, and a snapshot of the page content. That snapshot is what a later check gets compared against, so saving an account is what makes change detection possible for it.
Where should I go if I need help?
Start with the documentation for setup and workflow details, then use Discord or email support if you need direct help.
