What is Double?
Double is moving the whole bookkeeping workflow into a chat assistant, one billable task per week.
Double ships weekly, and for two months straight nearly every release has been another accounting task absorbed into Ask Double: transactions in late June, live spreadsheets, AI workpapers, metrics creation, voice input, and now Connections to outside tools. The assistant has gone from answering questions about the books to creating the artifacts accountants bill for. The most recent entry breaks the pattern — role-based restrictions on who can edit client properties — which is the administrative counterweight to everything else.
What is Outline?
Outline gave AI assistants write access to the wiki, then spent months on the human side.
The April MCP expansion is the structural change in this window: assistants can patch documents, move and delete documents and collections, work with attachments, and create and resolve inline comments. Everything since has been human-facing and smaller — request-access flows for documents members cannot open, email subscriptions to publicly shared documents with change summaries, task list and checkbox handling in the editor, and profile cards on avatar hover.

Double is moving the whole bookkeeping workflow into a chat assistant, one billable task per week.
◆ Current state
Double ships weekly, and for two months straight nearly every release has been another accounting task absorbed into Ask Double: transactions in late June, live spreadsheets, AI workpapers, metrics creation, voice input, and now Connections to outside tools. The assistant has gone from answering questions about the books to creating the artifacts accountants bill for. The most recent entry breaks the pattern — role-based restrictions on who can edit client properties — which is the administrative counterweight to everything else.
◆ Where it's heading
The strategy is to make Ask Double the primary interface and reduce the app's tab-by-tab surface to a system of record behind it. Two constraints are being addressed in parallel: the assistant needed to reach data Double does not hold, which Connections solves, and firms needed guardrails before handing an assistant this much reach, which the permissions work starts. Exposing metrics through both Ask Double and an MCP/API endpoint suggests Double expects agents outside its own product to drive the platform too.
◆ Prediction
Connections should exit private beta and expand its connector list, since it is the dependency for the cross-tool briefings Double is pitching. Expect the permissions model to keep hardening in step with each new thing the assistant is allowed to create.
Outline
2.5COLLAB
Outline gave AI assistants write access to the wiki, then spent months on the human side.
◆ Current state
The April MCP expansion is the structural change in this window: assistants can patch documents, move and delete documents and collections, work with attachments, and create and resolve inline comments. Everything since has been human-facing and smaller — request-access flows for documents members cannot open, email subscriptions to publicly shared documents with change summaries, task list and checkbox handling in the editor, and profile cards on avatar hover.
◆ Where it's heading
Two audiences are being served in sequence. The MCP work moved assistants from reading the knowledge base to editing it, including the collection structure itself. The releases after it close ordinary gaps in how people find, follow and get into documents — which is what a wiki needs before more of its edits arrive from automation. Release cadence is roughly monthly with entries that describe outcomes rather than changelogs.
◆ Prediction
Expect the human-facing polish to continue at its current pace, with any next structural move likely extending the MCP surface further into permissions and collection management, since that is where the existing tools stop.
