What is Double?
Ask Double can now read and post in Microsoft Teams on an accountant's behalf.
Double is an accounting-practice platform built around QuickBooks Online, with the Ask Double assistant at its centre. The October 22 release connects Ask Double to Microsoft Teams, where it can read chats and channels and send messages as the user after confirmation, and lets it draft executive summaries and act on batches of tasks. Bookkeeping work continues alongside: customer-level and whole-P&L allocations, partial fixed-asset disposals and reminders for every open client request. The week before brought Ask Double to Xero and Consolidations in beta.
What is Reflect?
Reflect's quiet SQLite frontend rewrite reset its performance ceiling and unblocked the AI roadmap.
Reflect is a personal note-taking app with embedded AI features (chat, transcription, summarization). The structurally important move of the year was a frontend rewrite onto SQLite, shipped across iOS, web, macOS, and then iPad over March 2025 — fixing the load-time and large-collection ceilings that had been quietly limiting the product. The rest of the visible cadence has been AI surface work: in-line voice transcription, Gemini for long-context chat, AI link summaries that feed semantic search, and an editor for custom prompt templates.

Ask Double can now read and post in Microsoft Teams on an accountant's behalf.
◆ Current state
Double is an accounting-practice platform built around QuickBooks Online, with the Ask Double assistant at its centre. The October 22 release connects Ask Double to Microsoft Teams, where it can read chats and channels and send messages as the user after confirmation, and lets it draft executive summaries and act on batches of tasks. Bookkeeping work continues alongside: customer-level and whole-P&L allocations, partial fixed-asset disposals and reminders for every open client request. The week before brought Ask Double to Xero and Consolidations in beta.
◆ Where it's heading
Two tracks run in parallel: fuller QBO bookkeeping coverage and an AI layer that reaches across a firm's tools. Teams is the first connector in these entries where Ask Double writes outside the ledger, not just reads, with a confirmation step as the guardrail. The assistant is becoming the way staff operate Double in bulk, from tasks to reports.
◆ Prediction
Expect more write-capable connectors with the same confirm-before-send pattern, and Ask Double on Xero gaining write actions after its read-only beta.
Reflect
0.0COLLAB
Reflect's quiet SQLite frontend rewrite reset its performance ceiling and unblocked the AI roadmap.
◆ Current state
Reflect is a personal note-taking app with embedded AI features (chat, transcription, summarization). The structurally important move of the year was a frontend rewrite onto SQLite, shipped across iOS, web, macOS, and then iPad over March 2025 — fixing the load-time and large-collection ceilings that had been quietly limiting the product. The rest of the visible cadence has been AI surface work: in-line voice transcription, Gemini for long-context chat, AI link summaries that feed semantic search, and an editor for custom prompt templates.
◆ Where it's heading
Reflect is closing the desktop-mobile parity gap one feature at a time (advanced search filters made the jump from desktop to iOS in August) while making the AI surface more configurable and more entangled with search. The team's own July release explicitly named AI chat on mobile as the next milestone. The pattern: ship the architectural foundation, then layer the AI features that depend on it.
◆ Prediction
AI chat on mobile is the next named milestone from the team's own published roadmap notes. Beyond that, expect more features that quietly feed AI-generated context into search (the link-summary pattern extended to OCR'd PDFs, voice transcripts, etc.) and continued performance work that exploits the SQLite rewrite.
