Show HN: Signal ChatGPT bot, with image generation and TTS [video]

I had a few hours to kill today, so I made a ChatGPT Signal bot, because what better UI to talk to an artificial person than the one I talk to real people on?

Tomorrow I aim to add speech recognition (send it voice notes and it'll understand what you're saying) and vision (send it photos and it can look at them).

You can't use it yet (please don't spam my phone number), but if it's popular I might add a "bring your own key" mode.
