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 SiYuan?

SiYuan 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.

SiYuan moved 3.8.9 from beta.6 to rc.1 on Oct 28. The RC's only new item is AI-agent extraction of images embedded in PDFs; the rest of its long list matches beta.5's cumulative notes: pinned agent sessions, backlink filtering by database fields, block-reference collection through database automation, resizable table rows, mind-map themes and node copy/paste, TIFF previews and macOS proxy detection.

Contractbook vs SiYuan: 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.

5.0

SiYuan 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.

◆ Current state

SiYuan moved 3.8.9 from beta.6 to rc.1 on Oct 28. The RC's only new item is AI-agent extraction of images embedded in PDFs; the rest of its long list matches beta.5's cumulative notes: pinned agent sessions, backlink filtering by database fields, block-reference collection through database automation, resizable table rows, mind-map themes and node copy/paste, TIFF previews and macOS proxy detection.

◆ Where it's heading

The 3.8.x line keeps turning databases and mind maps into structured tools that act on the block graph, and the built-in agent is gaining reach into document content such as PDFs. The release cadence is fast and noisy, with most builds repeating the same cumulative notes.

◆ Prediction

A stable 3.8.9 is likely within days, with little added beyond fixes now that it has reached RC.
