SleekFlow is an inbox for many channels, priced by user seats and monthly active contacts, with AI agents from its Pro plan and a monthly fee for each WhatsApp number. Syniria includes its AI agent in every plan from Starter: it answers, books the appointment, takes the order and keeps the customer record, and your WhatsApp campaigns go out from the same workspace.
Checked
Syniria answers every message, then does the work that follows, in one workspace your team shares.
Built in, with no separate booking tool to pay for: services, staff, weekly schedules, buffers and booking rules. Customers book in the chat or on a booking page you link from your website, then reschedule or cancel by link.
The agent looks up live prices, options, stock and photos, then turns the chat into an order your team tracks to the end.
One contact across WhatsApp, Instagram, Messenger, Telegram and your website, with notes, tags, stages and follow-up tasks for your team.
Send approved templates to the people you choose, now or on a schedule. Opt-outs are respected, and replies come back to the inbox.
Owner, Manager and Agent roles, assigned conversations, and a takeover that pauses the AI until the chat is handed back.
Your agent answers on WhatsApp, Instagram, Messenger, Telegram and your own website, for businesses worldwide, clinics, salons and stores alike, with no waitlist.
