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 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 vs Kagi Search: editorial side-by-side

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.

K0.0

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.
