What is Contractbook?
Contract automation grows up: admin permission maps, 2FA, and forms that do their own arithmetic.
Contractbook released a batch of six changes on a single day covering three areas at once. Administration gets a company-wide Spaces access page answering who can reach which space and with what permission, plus OTP two-factor authentication at login. Contract creation gets calculation fields in forms that compute totals and pro-rated amounts and insert them into the document automatically. The AI side gets a new extraction model and a dedicated place to manage AI upload contract types, with built-in defaults now editable per company.
What is SiYuan?
SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0
SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.
Contractbook vs SiYuan: editorial side-by-side
Contractbook
5.0COLLAB
Contract automation grows up: admin permission maps, 2FA, and forms that do their own arithmetic.
◆ Current state
Contractbook released a batch of six changes on a single day covering three areas at once. Administration gets a company-wide Spaces access page answering who can reach which space and with what permission, plus OTP two-factor authentication at login. Contract creation gets calculation fields in forms that compute totals and pro-rated amounts and insert them into the document automatically. The AI side gets a new extraction model and a dedicated place to manage AI upload contract types, with built-in defaults now editable per company.
◆ Where it's heading
The pattern is a product being fitted for larger customers: the access-visibility page is gated to Accelerate and Enterprise plans, group-level company permissions landed earlier in the year, and 2FA closes the obvious procurement objection. Meanwhile the AI features are moving from fixed behaviour toward configurable behaviour — extraction types are now a company's own list rather than the vendor's. Calculations remove the last common reason to edit a generated .docx by hand.
◆ Prediction
The admin thread points toward more permission surface — audit trails or per-space delegation would follow naturally from a page that already explains where each permission comes from. Nothing in these entries indicates how much extraction accuracy actually improved.
SiYuan
6.3COLLAB
SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0
◆ Current state
SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.
◆ Where it's heading
This is consolidation of the surface 3.8.0 opened, not an extension of it. The agent, semantic search and MCP endpoint arrived in the 3.8.0 line; 3.8.1 makes them portable and pluggable - skills come from a directory the user controls, editor actions follow the user between devices, and the provider layer now speaks the OpenAI Responses API rather than one bespoke shape. The high beta count against a modest final diff shows a project stabilising a young subsystem rather than building a new one.
◆ Prediction
The next line most likely pushes on the skills directory - discovery, sharing or marketplace distribution of user-level skills - since that is the piece 3.8.1 made user-editable without giving it a distribution path.
