Every conversation.
One contact that remembers.

OneContact reads the chats you already have — WhatsApp, Telegram, Gmail, Slack and more — and keeps every birthday, promise and detail about the people you know in one place. Then it reminds you at the right moment.

How it works

Every chat in WhatsApp, Telegram, Gmail, Slack and Outlook. One contact.

Connect the apps where your conversations happen. OneContact merges each person across all of them — then gives you back what matters.

Why OneContact

Your relationships live in a dozen apps. Your memory can’t keep up.

  • One card per person

    James on WhatsApp, James on Gmail and James in your contacts become one person — with their job, family, birthday, last conversation and open promises, each fact linked to where it came from.

  • Nudges at the right moment

    Birthdays, follow-ups and promises you’re about to forget — with quiet hours built in.

  • Meeting briefs

    Who they are and what you last discussed — 30 minutes before you meet.

  • Just say it

    “James’s birthday is August 31.” Hold to talk and it’s saved to James.

  • Drafts in your voice

    Replies that sound like you. Nothing is sent until you tap send.

Nudges

Exactly when it matters.Never a moment too late.

  • Birthdays & milestones — a few days ahead, with a draft ready.
  • Meeting briefs — 30 minutes before you meet.
  • Open promises — before they turn awkward.
  • Trips — everyone you said you’d see there.
  • Quiet hours — nothing at night unless you want it.
