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 Double?
Double turns a recorded Chrome session into an agent that repeats the task.
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.
Contractbook vs Double: 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.
Double
8.8COLLAB
Double turns a recorded Chrome session into an agent that repeats the task.
◆ Current state
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.
◆ Where it's heading
Double is moving from an assistant that answers to agents that do recurring work, and is now letting firms create those agents by showing rather than configuring. Usage caps, permission levels and a web-browsing switch that is off by default show it adding controls as agents get more reach.
◆ Prediction
Expect more agent templates and recorder support for other client systems, plus wider Xero coverage after the US bank feeds launch.
