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.

What is Double?

Double restructures AI pricing with a 93%-cheaper Standard tier, making Ask Double viable at full-book scale

Double is an AI-first accounting platform built for accounting firms managing multiple clients. Over the past two months the product has aggressively extended its Ask Double AI assistant — building workpapers, importing accruals, managing metrics, routing bank transactions from raw PDFs, and now auto-routing queries across a three-tier model stack. The Sep 10 model restructuring is the culmination: with a Standard tier 93% cheaper than Expert and an Auto mode that routes per-query complexity, Double has shifted AI accounting from a premium add-on into an economically viable default across every client account. The interactive financial statement suite — P&L, Balance Sheet, and Cash Flow — is now complete.

Kagi Search vs Double: editorial side-by-side

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.

Double restructures AI pricing with a 93%-cheaper Standard tier, making Ask Double viable at full-book scale

◆ Current state

Double is an AI-first accounting platform built for accounting firms managing multiple clients. Over the past two months the product has aggressively extended its Ask Double AI assistant — building workpapers, importing accruals, managing metrics, routing bank transactions from raw PDFs, and now auto-routing queries across a three-tier model stack. The Sep 10 model restructuring is the culmination: with a Standard tier 93% cheaper than Expert and an Auto mode that routes per-query complexity, Double has shifted AI accounting from a premium add-on into an economically viable default across every client account. The interactive financial statement suite — P&L, Balance Sheet, and Cash Flow — is now complete.

◆ Where it's heading

Double is building toward a full AI-agent accounting platform, not just a chat interface bolted onto bookkeeping software. The AI Agents private beta (automating recurring tasks on a schedule or event trigger), the MCP/API surface for programmatic control, and the Connections feature (reaching into Slack, Notion, HubSpot) all point to Double becoming an orchestration layer for accounting firms. The model pricing restructure signals that Ask Double is expected to run on virtually every client action, with human review reserved for exceptions rather than the default. The direction is clear: make AI the primary work surface and treat the accounting firm's judgment as the final gate.

◆ Prediction

The next move is most likely graduating the AI Agents beta to general availability — converting scheduled automation and event-trigger workflows from a differentiated beta into a standard tier feature. Expansion of the Connections library beyond Slack, Notion, and HubSpot is also probable, since cross-tool context is a prerequisite for agents to make decisions autonomously.
