A dialer and address book that actually works for you.
From the first keypress to a shareable vCard — here's the full toolkit.
Smart T9 dialer & keypad
Tap out a name on the number pad and T9 surfaces the right contact instantly. Flip to a full alphanumeric keyboard whenever you prefer — both feed the same search.
Quick channels
Reach anyone through Call, SMS, WhatsApp, Telegram, Signal or Viber — one tap opens the right app with the number pre-filled.
Speed dial
Pin the people you reach most to a speed-dial row so they are always a single tap away.
Smart history & frequent
Recents and a frequently-contacted list are built automatically, so the right person is always near the top.
Universal finder
One search spans your contacts, people on Sayzio, your links & biolinks and your workspaces — grouped by category with a clear action for each result.
Call logging & reminders
Log call outcomes and set callback reminders so follow-ups never slip through the cracks.
Spam & block controls
Flag and block unwanted numbers to keep your dialer and caller ID clean.
Two-way Google Contacts sync
Contacts stay in lockstep with Google via the People API — edits made anywhere flow both directions, incrementally and on a schedule.
Phone → biolink resolution
Incoming and saved numbers resolve to rich Sayzio profiles, silently attaching the matching biolink (with detach memory).
Rich identity profiles
Every contact holds multiple numbers, emails, addresses, socials and organisations — not just a single field.
Bulk CSV / vCard import
Import large lists via a parse → preview → confirm flow, skipping rows before you commit, with big files processed in the background.
AI business-card scanner
Snap a business card or brochure and AI extracts names, numbers, emails and socials straight into a clean new contact.
Reach anyone, however they prefer.
Every contact carries the channels they actually use. Skip the copy-paste dance — tap once and Sayzio opens the right app with the number ready to go.
Two-way Google Contacts sync, on autopilot.
Add a contact on your phone, edit one in Sayzio — both stay identical. Changes flow both ways, incrementally, on a schedule and the moment you make them.
Import a spreadsheet or just snap a card.
Bring in a whole list from CSV or vCard with a safe parse → preview → confirm flow — skip the rows you don't want before anything is saved, and let big files finish in the background. Or point your camera at a business card and let AI do the typing.
- Preview every row and skip duplicates before committing
- Large imports run as a background job with live progress
- AI card & brochure scanning fills names, numbers, emails & socials
- Export any contact as a shareable vCard in one tap
The full T9 dialer, quick channels and caller ID experience also ships as its own dedicated companion app, Sayzio Dialer — alongside everything you already get inside the main Sayzio app.
Sayzio & Dialer are
Two powerful apps in one ecosystem. Sayzio lets you manage links, biolinks and QR codes and watch your stats live from your pocket. Dialer brings a smart T9 dialer and caller ID that resolves any number to a full Sayzio profile — so you always know who's calling.
Turn your contacts into conversations.
Bring your address book to Sayzio and get a smart dialer, quick channels, Google sync and phone-to-profile caller ID — free to start.
