I built DialDo: a phone number that can ask your Mac to do work

Description and use

DialDo lets users control a Mac via a phone call, executing described tasks and confirming completion.

Problem

Users need to control a Mac from a phone while away from the desk, but remote desktop on a small screen is awkward.

Outcome

DialDo enables users to perform file, PDF, browser, and app workflows on an Apple Silicon Mac via a phone call, with task completion confirmation and short spoken replies.

Workflow

• Call personal number via Twilio
• Twilio forwards call to Railway gateway
• Gateway identifies caller number and routes to correct Mac over authenticated connection
• OpenAI transcribes call and plans task
• Mac app performs file, document, browser, and macOS automation steps
• Mac app verifies evidence from each step before reporting completion
• Phone receives short spoken reply and text notification when done

Evidence

I built DialDo. It gives each user a personal phone number linked to their Mac. You call, describe a task, confirm the overall request once, and the Mac app works through the steps.

Source

Twilio receives the call and sends it to a small gateway on Railway. The gateway identifies which number was called and routes that conversation over an authenticated outbound connection to the right Mac.

OpenAI transcribes the call and helps plan the task. The Mac app then uses local file, document, browser, and macOS automation tools to carry it out.

This is an early release for Apple Silicon Macs. It can handle useful file, PDF, browser, and app workflows, but UI automation is imperfect: a changed website, sign‑in prompt, or ambiguous instruction can still stop a task.
