Search your Outlook contacts with AI
Your Outlook inbox holds years of professional relationships. Happenstance indexes your email contacts and makes your entire network searchable with natural language.
Your Outlook network, unlocked
Search everyone you've emailed by role, company, or expertise, not just name
Search beyond names
Search your Outlook contacts by what people do, where they work, or their area of expertise. Not just by name or email address.
Headers only, never content
We only read email headers (to, from, date) and never the body of your emails. Your conversations stay completely private.
Automatic sync via OAuth
Connect with one click via Microsoft OAuth. Your contacts stay in sync automatically as new emails arrive.
