Interact
Interact opens its intranet to outside AI assistants and uses Claude to attack its own platform.
A side-by-side editorial comparison of Tana and Double — release velocity, themes, recent moves, and the top alternatives to consider.
Tana now records meetings around one laptop and adds Lovable and Ari as agents.
Tana has turned into a meeting workspace: a meeting-timeline Home, live suggestions that draft tasks for approval, research briefs and an iPhone app. October 26 let users bring their own Claude or ChatGPT into calls. The November 12 release captures in-person and hybrid meetings, splits several voices on one microphone into separate speakers, lets users name transcript speakers, and adds Lovable and cfo.ai's Ari as external agents that answer privately inside meetings.
Double turns a recorded Chrome session into an agent that repeats the task.
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.

Tana is covering every kind of meeting, including the ones where people share a room, and opening its meeting surface to more outside agents. Enterprise admins can now choose which external agents members may use, the governance step that usually precedes a wider agent catalog.
Expect more external agents added to the Settings list and agent actions tracked in Work's Waiting on you, as the November release began with status rows for accepted actions.
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.
Double is moving from an assistant that answers to agents that do recurring work, and is now letting firms create those agents by showing rather than configuring. Usage caps, permission levels and a web-browsing switch that is off by default show it adding controls as agents get more reach.
Expect more agent templates and recorder support for other client systems, plus wider Xero coverage after the US bank feeds launch.
