InsightBee vs Seamless.AI
Numbers that come to you, instead of one lookup at a time.
At a glance
InsightBee or Seamless.AI?
Choose InsightBee if…

The core difference
Where the numbers come from
Numbers come from a source databases don’t have: out-of-office replies from your own contacts. An out-of-office reply names who is covering right now and how to reach them.
Connect your CRM
Any CRM, live in under a day.
Out-of-office replies surface
InsightBee surfaces out-of-office replies from your existing contacts. Nothing is ever sent to them.
Numbers are written back
Mobiles, direct dials and replacement contacts are verified and written back to your CRM.

Seamless.AI in brief
Why it matters
From searching to receiving
A search tool starts with a search: someone has to decide whom to look for, run the search and spend a credit on the result.
InsightBee works without that step. It runs automatically inside your CRM and surfaces numbers from your contacts’ out-of-office replies – a reply that names who is covering right now and how to reach them – then writes them back to the contact record. No searching, no clicking, no browser extension.
Because the source is your own business correspondence, you can always say where a number came from. Not scraped. Not bought. No data broker chain.
