What is Contractbook?

Contractbook hands the AI's extraction prompts over to the customer

Contractbook publishes short, emoji-headed notes, most of them arriving in same-day batches. The August 3 batch covered admin permission maps across spaces, OTP two-factor at login, calculations inside forms, a rebuilt search results page, and a new model behind AI data extraction. This release opens the default data fields themselves: the prompts behind each AI-detected field can be rewritten or renamed per contract type.

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.

Contractbook vs Outline: editorial side-by-side

C5.0

Contractbook hands the AI's extraction prompts over to the customer

◆ Current state

Contractbook publishes short, emoji-headed notes, most of them arriving in same-day batches. The August 3 batch covered admin permission maps across spaces, OTP two-factor at login, calculations inside forms, a rebuilt search results page, and a new model behind AI data extraction. This release opens the default data fields themselves: the prompts behind each AI-detected field can be rewritten or renamed per contract type.

◆ Where it's heading

The AI extraction layer has been treated as a black box that Contractbook tunes and customers accept. Editable prompts break that — accuracy on a customer's own contract vocabulary becomes something they adjust rather than file a ticket about. It fits the wider pattern of the last few releases, where admin surfaces (space access maps, group permissions, contract-type management) are being built so companies can configure what used to be product defaults.

◆ Prediction

Once prompts are editable per contract type, per-field extraction quality becomes visible and arguable, so expect some form of confidence indicator or review step on extracted data 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.
