What is Double?

Double shifts AI economics: 93%-cheaper Standard tier and Claude Opus 5 Expert mode

Double ships on a weekly cadence with broad scope each cycle — Ask Double gains new capabilities (CSV/PDF bank imports, voice input, accruals from transactions), accounting workflows deepen (interactive financial statements across all three statements, revenue share allocations, loan receivables), and the AI model economics shift materially with the September 10 Standard/Auto/Expert tiering. The product ships Scale-tier and standard features simultaneously, signaling active enterprise expansion alongside the core SMB base.

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 shifts AI economics: 93%-cheaper Standard tier and Claude Opus 5 Expert mode

◆ Current state

Double ships on a weekly cadence with broad scope each cycle — Ask Double gains new capabilities (CSV/PDF bank imports, voice input, accruals from transactions), accounting workflows deepen (interactive financial statements across all three statements, revenue share allocations, loan receivables), and the AI model economics shift materially with the September 10 Standard/Auto/Expert tiering. The product ships Scale-tier and standard features simultaneously, signaling active enterprise expansion alongside the core SMB base.

◆ Where it's heading

The AI Agents private beta — scheduled automation of recurring accounting tasks across clients — is the clearest signal of where Double is heading: not AI-assisted closes but AI-executed ones, with human handoff on review steps. The Double MCP surface gains new actions each week, and the interactive financial statement suite is now complete with Cash Flow, setting the stage for cross-statement analysis. Model tiering changes the adoption math for heavy users, which could accelerate the active-usage cohort.

◆ Prediction

A general release of the AI Agents feature (currently private beta, announced in August) is the most significant move in the pipeline. More Scale features converting to standard tier is the growth pattern visible across the last 6 weeks of releases.

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.
