hiify.ai flow builder showing a front-desk call workflow

  • Visible

    Every question, action, and handoff stays on the canvas.

  • Grounded

    Answers come from the sources you attach to the flow.

  • Connected

    Use supported calendars, CRMs, reservations, and app actions.

From idea to live call

Build it in the same order you would train a new teammate.

Start with the job. Make the decisions visible. Add approved material and connected tools. Then test the real experience before you publish.

What goes on the canvas

Not a black box. A workflow you can read.

Each step has a job. You decide what the agent asks, what it may answer, which tool it can use, and when a person takes over.

  • Visible call logic

    Ask, collect, branch, wait, take a message, or end the call with an explicit step.

  • Approved answers

    Attach ready files, web pages, or text to the knowledge step that needs them.

  • Appointments and tables

    Check live availability and use the actions supported by the calendar or reservation provider.

  • Connected actions

    Save contacts, send an SMS, notify a team, or run a supported app or n8n action.

  • A clear way out

    Transfer the caller or leave a structured message when a person needs to take over.

  • A record after the call

    Keep the transcript, channel, duration, and available outcome together in the inbox.

Channels

Start on the web. Add the phone line when it is ready.

Choose web, phone, or both when you create an agent. Phone publishing needs a connected Twilio number and a configured voice runtime.

  • Web only

    Test on your website

    Publish a voice-and-text widget without connecting a phone number.

    • Embeddable widget
    • Voice and text
    • Shared flow and knowledge

  • Voice only

    Connect your phone line

    Route inbound calls from a Twilio number you connect to the published agent.

    • Bring your Twilio account
    • Inbound calls
    • Human transfer paths

  • Web + Voice

    Use the same agent for both

    Keep one editable flow behind the website widget and the phone line.

    • One flow
    • One knowledge set
    • One conversation inbox
Connected work

The call can end with the work already done.

Add the apps your team already runs, then place their supported actions directly in the conversation flow.
