It's pretty much just Claude Code, except hooked up to your Telegram / WhatsApp / iMessage.

I don't know why they don't make an official integration for it. Probably cause they're already out of GPUs lol

Claude Code does now have integration with Telegram, Discord, and iMessage as of a few weeks ago:

I haven't used OpenClaw since then ...
