Hello, I am Kevin, the instructor for the OpenClaw.AI basic course.

I am writing to inform you that [Basic Part 2] OpenClaw.AI Master Class: A Smartphone Remote Assistant Completed with Telegram and Vision AI has been released on Inflearn. ^^

I hope my lecture can be of even a little help in allowing you to utilize OpenClaw smartly in your daily life.

👉[Go to OpenClaw.AI Basics Part 2 Lecture]

What we will create together in Part 2

- Build an environment to remotely control your agent anytime, anywhere using Telegram on your smartphone.

- Complete a household account book routine where a single receipt photo is automatically analyzed and recorded using Gemini 2.5 Flash's vision capabilities.

- Upgrade the Docker + workspace environment created in Part 1 into a real-world automation scenario.

Especially recommended for these people

- Those who say, "Now I want to use agents on my smartphone without a browser."

- Those who want AI to automatically classify and record receipt/image data instead of manually organizing it every time.

- Those who want to connect OpenClaw, which they only got a taste of in Part 1, to actual work/life automation.
