Interact
Interact opens its intranet to outside AI assistants and uses Claude to attack its own platform.
A side-by-side editorial comparison of Capacities and Double — release velocity, themes, recent moves, and the top alternatives to consider.
Capacities rebuilds its tablet app and moves audio recording down to Pro.
Capacities ships a named release about monthly. November's rebuilds the iPad and Android tablet app, moves audio recording and analysis into the Pro plan, and starts reminders in early testing for Believer subscribers. October added whiteboards and a global graph view, and September brought audio transcription and AI chats that can edit objects.
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.

Capacities keeps a pattern of trialling features with Believers and then moving them down to Pro, as it did with bulk import, image analysis and now audio. The tablet rebuild suggests more attention to devices beyond desktop.
Reminders will likely leave Believer-only testing in a coming monthly release and move toward Pro, following the audio path.

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.
