What is Document360?

Document360 rebuilt its API for agents; now it's turning the AI inward on authoring.

Monthly point releases on a steady 12.x line, each a themed bundle rather than a fix list. The last three releases rebuilt the developer-facing surface: an interactive API reference with an in-page Try It! console, a ground-up API v3 with OAuth 2.0 and scoped keys, and a Widget 2.0 embedding architecture now rolling out with a migration deadline. Around that, Eddy AI and the MCP server have been gaining governance controls — reader-group restrictions, workflow permissions, usage analytics — more often than new capabilities.

What is Double?

Double is turning its accounting assistant into the way the work gets done

Double ships weekly, and nearly every release extends Ask Double rather than the surrounding application. In the last two months it has learned to build workpapers by reconciling accounts against supporting documents, import accruals, create and manage client metrics through the MCP and API, take voice input, and — in private beta — reach into Slack, Notion, and HubSpot. The non-assistant work fills in what firms need to trust that: role-based restrictions on editing client properties, and check transactions in AI Transactions.

Document360 vs Double: editorial side-by-side

D6.3

Document360 rebuilt its API for agents; now it's turning the AI inward on authoring.

◆ Current state

Monthly point releases on a steady 12.x line, each a themed bundle rather than a fix list. The last three releases rebuilt the developer-facing surface: an interactive API reference with an in-page Try It! console, a ground-up API v3 with OAuth 2.0 and scoped keys, and a Widget 2.0 embedding architecture now rolling out with a migration deadline. Around that, Eddy AI and the MCP server have been gaining governance controls — reader-group restrictions, workflow permissions, usage analytics — more often than new capabilities.

◆ Where it's heading

Two threads run through the year. One makes the knowledge base machine-readable and machine-writable: MCP server, automatic llms.txt, open-an-article-in-ChatGPT-or-Claude, then API v3. The other fences that access with admin controls before enterprise buyers have to ask. The newest release turns the AI inward for the first time — the redesigned Publish dialog puts suggestions and validation in the author's path rather than the reader's, which is a different customer for the same capability.

◆ Prediction

The AI suggestions now sitting in the Publish dialog are the obvious candidate to move into the editor itself, and the advanced v3 endpoints sold as an add-on look like the seed of a higher API tier. The Widget 2.0 forced migration is the near-term execution risk, since it puts required technical work on existing customers to a fixed timeline.

Double is turning its accounting assistant into the way the work gets done

◆ Current state

Double ships weekly, and nearly every release extends Ask Double rather than the surrounding application. In the last two months it has learned to build workpapers by reconciling accounts against supporting documents, import accruals, create and manage client metrics through the MCP and API, take voice input, and — in private beta — reach into Slack, Notion, and HubSpot. The non-assistant work fills in what firms need to trust that: role-based restrictions on editing client properties, and check transactions in AI Transactions.

◆ Where it's heading

The assistant is moving from answering questions to performing the billable work — tie-out, accrual setup, metric standardization across a whole book of clients. Each release pairs that with an access or permissions control, which is the pattern of a vendor that knows the objection is liability rather than capability. The accounting engine itself keeps advancing underneath, most recently with prepaid contracts paid in installments.

◆ Prediction

Given the review-and-signoff question these features raise, the likely next step is an approval or audit trail around what Ask Double produces rather than another task it can perform.
