Control Alter from your phone

TL;DR: Gateways are coming to Alter. It lets you connect Discord and Telegram, so you can send messages, record voice notes, answer follow-up questions, retrieve files, and run your existing Alter actions — all while Alter runs locally on your Mac.

Important: Gateways are connections to Alter running locally. Alter must remain open on your Mac. This is not a cloud-hosted Alter instance.

Hub Split Panel

TL;DR: Split Panel lets you add a second panel next to your current Hub session — work in parallel on two tasks or one complex project without losing your place. Drag text between panes, move tabs side to side, @-reference the other panel, and open Markdown, HTML, or PDF files in a side panel with “Open in the other panel.”
