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 Outline?

Outline goes browser-native for AI agents with WebMCP, accelerating its bet on agentic knowledge management.

Outline has been shipping steadily across two tracks: UX refinements (split view, profile hover cards, task list improvements) and an increasingly serious MCP/agentic integration surface. The April MCP expansion added patching, moving, deleting, and inline comment tools. The September WebMCP drop goes further: in-browser AI agents can now discover and call Outline's structured tools directly through document.modelContext, requiring no server-side MCP connection. That makes Outline one of the first knowledge tools to adopt the browser-native agent discovery standard.

Kagi Search vs Outline: 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.

6.3

Outline goes browser-native for AI agents with WebMCP, accelerating its bet on agentic knowledge management.

◆ Current state

Outline has been shipping steadily across two tracks: UX refinements (split view, profile hover cards, task list improvements) and an increasingly serious MCP/agentic integration surface. The April MCP expansion added patching, moving, deleting, and inline comment tools. The September WebMCP drop goes further: in-browser AI agents can now discover and call Outline's structured tools directly through document.modelContext, requiring no server-side MCP connection. That makes Outline one of the first knowledge tools to adopt the browser-native agent discovery standard.

◆ Where it's heading

Outline is positioning itself as an agent-native knowledge base rather than just a polished wiki. The pattern across the last several releases is deliberate: MCP support expanded significantly in April, Open Knowledge Format export added portability in September, and WebMCP makes the agent integration surface browser-accessible. The OKF export is also a meaningful portability move — structured markdown bundles that survive outside Outline reduce lock-in risk and could attract teams evaluating it against more closed alternatives.

◆ Prediction

Outline will likely expand the WebMCP tool surface — the April MCP work gave them a solid set of structured tools to expose, and WebMCP makes those available without setup friction. Expect more agent-facing capabilities (summarization, cross-document linking, task extraction) rather than another round of baseline UX polish.
