Double vs Guru: at a glance
What is Double?
Double's AI assistant reaches past QuickBooks into Xero.
Double is an accounting-practice platform built around QuickBooks Online, with the Ask Double assistant at its centre. The October 15 release puts Ask Double on Xero clients in a read-only beta and adds Consolidations, a beta for multi-entity QBO clients with account mapping and elimination rules. It follows Connectors opening to any MCP server and invoices gaining tax, terms and custom fields.
What is Guru?
Guru is tightening the leash on the Knowledge Agent it just handed the keys to.
Everything recent is the Knowledge Agent. It already writes to the knowledge base — creating collections, bulk-archiving cards, running drafts through to publish — and the newest work narrows where and how it acts: per-channel behaviour in Slack, and skills pinned to a named document instead of searching for one. Around that sit guardrails, skill permissions, recoverable drafts and scheduled automations.

Double
7.5COLLAB
Double's AI assistant reaches past QuickBooks into Xero.
◆ Current state
Double is an accounting-practice platform built around QuickBooks Online, with the Ask Double assistant at its centre. The October 15 release puts Ask Double on Xero clients in a read-only beta and adds Consolidations, a beta for multi-entity QBO clients with account mapping and elimination rules. It follows Connectors opening to any MCP server and invoices gaining tax, terms and custom fields.
◆ Where it's heading
Two tracks run in parallel: fuller QBO bookkeeping coverage, now including multi-entity consolidation, and an AI layer that reaches across a firm's tools. Xero support arriving through Ask Double first, read-only, shows the assistant is the wedge for expanding beyond the QBO ledger.
◆ Prediction
Expect Ask Double on Xero to gain write actions after the read-only beta, and Consolidations to stay a Scale-tier feature. Whether Xero gets the full close workflow is not shown in the entries.
Guru
5.0COLLAB
Guru is tightening the leash on the Knowledge Agent it just handed the keys to.
◆ Current state
Everything recent is the Knowledge Agent. It already writes to the knowledge base — creating collections, bulk-archiving cards, running drafts through to publish — and the newest work narrows where and how it acts: per-channel behaviour in Slack, and skills pinned to a named document instead of searching for one. Around that sit guardrails, skill permissions, recoverable drafts and scheduled automations.
◆ Where it's heading
The arc is autonomy first, then control. Having given the agent write access and a schedule, Guru is now spending releases on determinism and scoping — making the agent's behaviour predictable per channel and its grounding exact per skill. That is the work required before customers let an agent run unsupervised on a knowledge base, and it suggests trust, not answer quality, is the constraint being engineered against.
◆ Prediction
The scoping controls point toward auditability as the next gap: some record of what the agent did to the knowledge base, and per-skill or per-channel review of those actions, to match the permissions and guardrails already shipped.
