Your people, kept.
Your Outlook contacts, on AI autopilot. You meet people faster than you can save them. Signatures pile up, numbers get lost, and Outlook only autocompletes email addresses — it never builds the contact. ContactGleaner does: it reads your inbox, meetings, and signatures and creates complete records for you to approve.
It runs on its own in the background — even when your computer is off. Review and approve what gets saved, or turn on Fully Automatic and let the new contacts it's confident about go straight into your Outlook for you.

The contacts you lose every week
Not because you don't care — because there's never a moment to type them in.
The person you emailed but never saved
Weeks of back-and-forth, then the thread goes quiet. Their name and direct line are buried in there — never in your contacts.
The signature you meant to copy
Name, title, direct line — sitting in an email you'll never reopen.
The attendee you can't find
You met on a call last month. Now you can't remember where to even look.

How it works
Connect your Outlook
Sign in with your Microsoft 365 account. One click, standard Microsoft sign-in — we never see your password.
AI finds your contacts
No more copy-pasting signatures. We scan your inbox, sent mail, and meetings, and AI reads signature blocks for the full picture — names (with nicknames and suffixes), professional credentials, job title, company, phone, and more.See everything we capture →
You review, we save
Approve each contact one at a time, or all at once. On paid plans, turn on Fully Automatic and the new contacts it's confident about are saved to your Outlook for you — nothing ambiguous ever slips through.
Four sources, one address book
Every person you already talk to becomes a complete, saved contact — without you typing a thing.
Inbox
Everyone who emails you, captured automatically.
Sent mail
The people you write to — To: and CC: recipients included.
Meetings
Every calendar attendee, even ones you've never emailed.
Signatures
AI reads signature blocks for name, title, company, phone, alternate email, and notes — plus nicknames, suffixes, and professional credentials.
Built private, on purpose
Your contacts come from your mailbox — and nowhere else
No data brokers. No scraping. No third-party lookups. We read signatures to build the contact, then your message content is gone. Sign in is standard Microsoft — we never see your password.

Questions, answered
What does ContactGleaner access?
Read access to your mail and calendar, and write access to your contacts. That's it. We use Microsoft's standard sign-in — we never see or store your password.
Is my email content stored?
No. We read signature blocks to extract contact details, save the contact, and move on. Your messages stay in your mailbox.
Do contacts get added without my approval?
By default, no. Every new contact lands in a review queue first — approve, edit, or skip each one. On paid plans you can turn on Fully Automatic: clean, unambiguous contacts are saved straight to your Outlook for you. Anything uncertain still waits in your queue.
Can I cancel anytime?
Yes. Downgrade or cancel whenever you like. Your saved contacts stay in your Outlook address book — they're yours.
What's a gleaner?
For centuries, a gleaner was someone who walked the fields after harvest, gathering the good grain left behind. Careful, patient work — nothing useful went to waste.
Your mailbox is that field. Every email and meeting invite carries details worth keeping: a name, a job title, a company, a direct number. Most of it sits in signature blocks and never reaches your address book.
ContactGleaner gathers it for you. It reads the signatures in your inbox, sent mail, and meetings, connects the pieces, and builds complete Outlook contacts. When someone changes companies or adds a new number, their record keeps up. And new contacts always wait in your review queue — nothing is saved without your okay.
That's the name on the door: we glean, so you don't have to.
Let us gather them for you.
Connect your Outlook and the contacts you've already earned start showing up — complete, accurate, and waiting for your okay.
