Yes — Sandbox mode lets you choose a different POTUS and set your own policies, and the persona reactions adjust to it.

btw, this bot could also transcribe voice notes to text.

It's a free service. All you need is the Bot's number to direct message to, and voila - you'll get a unique picture as a response.

Forward voice messages to this WhatsApp account +16506000350 and receive a transcription as a reply. Sometimes we don’t have time to listen or play back the voice note for whatever reason: in a meeting, no privacy, etc. And sometimes, the voice message is simply too damn long and we want to read it instead. Whatever the case, Stork for WhatsApp Bot is always on a standby to transcribe. Free.
