What is Contractbook?
Contractbook groups contracts with their amendments and renewals.
Contractbook's August batch focused on admin control and AI extraction: permission maps per space, OTP two-factor, calculations in forms, a rebuilt search page, a new extraction model and editable prompts behind default data fields. November adds linked contracts, which tie a main agreement to its amendments, renewals and supporting files and show them as one family, including on already uploaded contracts.
What is Interact?
Interact opens its intranet to outside AI assistants and uses Claude to attack its own platform.
Interact's October feed is led by Interact MCP, which brings the intranet into AI assistants people already use, with read and write access under each person's permissions. Its security team joined Anthropic's Cyber Verification Program and is testing its own platform with Claude Mythos 5.1, and Cyber Essentials certification now covers Interact and Sideways 6. The rest of the month is buyer guides, award news and thought leadership.
Contractbook vs Interact: editorial side-by-side
Contractbook
2.5COLLAB
Contractbook groups contracts with their amendments and renewals.
◆ Current state
Contractbook's August batch focused on admin control and AI extraction: permission maps per space, OTP two-factor, calculations in forms, a rebuilt search page, a new extraction model and editable prompts behind default data fields. November adds linked contracts, which tie a main agreement to its amendments, renewals and supporting files and show them as one family, including on already uploaded contracts.
◆ Where it's heading
The product is shifting from drafting and signing toward managing a contract repository after signature. Linked families and editable AI fields both make the stored contract record more accurate and easier to navigate.
◆ Prediction
Expect linked families to feed renewal tracking or reporting next, for example alerts when an amendment changes a key date, though the entries do not yet show that.
Interact
5.0COLLAB
Interact opens its intranet to outside AI assistants and uses Claude to attack its own platform.
◆ Current state
Interact's October feed is led by Interact MCP, which brings the intranet into AI assistants people already use, with read and write access under each person's permissions. Its security team joined Anthropic's Cyber Verification Program and is testing its own platform with Claude Mythos 5.1, and Cyber Essentials certification now covers Interact and Sideways 6. The rest of the month is buyer guides, award news and thought leadership.
◆ Where it's heading
The Spring Action Agent work put agents inside the intranet; MCP moves the intranet out to wherever employees already work. That raises the stakes on trust, which is why the security items matter more than they would alone: a system holding company knowledge is being opened to more clients. The company's content messaging now describes the intranet as adaptive.
◆ Prediction
Expect Conductor and MCP connections to reach more business systems, following the Workday pattern from the Spring Launch. Further security attestations are also likely as AI access expands.
