Seamless.AI
A browser extension that finds verified phone numbers and email addresses in real time as you browse LinkedIn and company pages.
What you'd use it for
Finding a decision-maker's direct phone number and email while you're already looking at their LinkedIn profile, so you can call or send today instead of switching tools to look them up first.
- Pull a verified email and direct-dial phone number for a LinkedIn profile or company page while you browse, without leaving the tab
- Search a claimed database of over 1.8 billion business emails and 414 million phone numbers by name, title, or company
- Refresh an existing CRM list automatically so outdated contact records get replaced with current ones
- Get credits refunded automatically when a phone number or email turns out to be invalid
- Draft outreach messages and build prospect lists with an AI assistant on paid tiers
The verdict
Seamless.AI does one plain thing well — it surfaces a phone number and email for whoever you're already looking at, inside the browser tab, which beats switching to a separate lookup tool. The free 50 credits are a genuine test of data accuracy for your industry, not a crippled trial. The catch is what happens once you like it — paid pricing is quote-only and billed annually, and by a wide margin of user reports, cancellation is the most complained-about part of the product, with a written-notice requirement well before renewal rather than a self-serve cancel button.

What you need to start
- Chrome browser, since Seamless.AI's real-time search runs as a Chrome extension
- An email, Google, or Microsoft account to sign up
Minutes to a free account and the extension installed; the first result appears on the very next LinkedIn profile you open, so the free tier itself is the whole evaluation.
Your first run Install the Chrome extension, sign up free with no credit card, and open a LinkedIn profile — the real-time search returns a phone number and email in the same session, and the 50 free credits are enough to judge accuracy in your own market before paying anything.
Where it breaks
Pro and Enterprise pricing is not published anywhere on the site — both route to a sales call, so the numbers above are placeholders for "you will negotiate this," not figures you can budget against without talking to them first.
First entry in this reference. There is no previous check to compare it against.
When not to use it
Not for anyone who wants to see a price before talking to a salesperson, or who might need to walk away on short notice — Seamless.AI's paid plans are annual contracts that, by widespread user report, require written cancellation weeks before renewal and auto-renew into another year if you miss that window. And because nobody in the database handed their details to you directly, reaching out to contacts in the EU or UK is your own GDPR obligation to satisfy, not one Seamless.AI's own compliance covers on your behalf once you've exported the data.
Seamless.AI is a prospecting tool in the oldest sense of the category: it finds a person’s phone number and email while you’re already looking at their LinkedIn profile or their company’s site, rather than making you switch to a separate lookup tool and paste in a name.
That real-time-while-browsing model is the whole pitch, and it’s a genuinely older idea than most of the AI tooling in this directory — Seamless.AI has been doing contact enrichment since well before “AI” was the marketing word for it. What’s changed more recently is the addition of an AI assistant layer on the paid tiers, which helps with list building and outreach sequencing rather than just data lookup.
The free tier is the actual test
Fifty credits a month is genuinely enough to judge whether the data is accurate for your industry and region before paying anything — contact enrichment tools vary a lot in hit rate by geography and job seniority, and this is the cheapest way to find out before committing.
What you can’t see before calling sales
Both paid tiers are quote-only, which is standard for this category but still worth flagging: unlike a self-serve SaaS with a public price ladder, you won’t know the real cost until a sales call, and it will vary by seat count and credit volume.
Against the alternatives
Against Lusha, the two are close competitors on the same job — Lusha publishes its prices openly where Seamless.AI does not, which makes Lusha the easier one to evaluate without a sales conversation.
