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 Kagi Search?
Kagi is unbundling itself: search as an API, Assistant as an app, AI as a switch.
The dated part of this feed stops in April on housekeeping releases — reliability work, refinements, a Small Web expansion. Everything since sits in undated rows and is more substantial: the Search API went to public preview in May carrying each account's own lenses and blocklists, June started rebuilding search widgets, July added a global off-switch for AI in search, and July 30 put Kagi Assistant on iOS and Android as a standalone app.

Double
7.5COLLAB
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.
Kagi Search
0.0COLLAB
Kagi is unbundling itself: search as an API, Assistant as an app, AI as a switch.
◆ Current state
The dated part of this feed stops in April on housekeeping releases — reliability work, refinements, a Small Web expansion. Everything since sits in undated rows and is more substantial: the Search API went to public preview in May carrying each account's own lenses and blocklists, June started rebuilding search widgets, July added a global off-switch for AI in search, and July 30 put Kagi Assistant on iOS and Android as a standalone app.
◆ Where it's heading
Kagi is separating what used to be one subscription into distinct products with distinct surfaces: a search index other people can query, an assistant that lives on a phone, and a search page where the AI layer is optional. The through-line is user control — preferences that follow the API key, widgets that can be switched off individually, threads that can be exported or deleted in bulk — which is the one thing an ad-funded competitor cannot match on. Growth now depends on those surfaces rather than on convincing people to change their default search engine.
◆ Prediction
The Search API is the piece with launch details still outstanding, so expect it to leave preview with firm pricing and the beta users migrated; the mobile Assistant is described as a first step, which points to the missing platform features arriving next.
