What is AFFiNE?
The nightly canary keeps shipping, and self-hosting just got a one-click path.
AFFiNE publishes a dated canary build most days alongside a slower beta line, and the two carry the same commits at different points on the maturity curve. The recent stream is maintenance-shaped: dependency security bumps in Mermaid and Electron, a journal lookup fix for trashed docs, retry handling for failed transcription jobs. The last directional move was workspace BYOK profiles with model catalogs and key rotation in early August, which sits on top of the MCP credential work from July.
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.
AFFiNE vs Contractbook: editorial side-by-side
AFFiNE
6.3COLLAB
The nightly canary keeps shipping, and self-hosting just got a one-click path.
◆ Current state
AFFiNE publishes a dated canary build most days alongside a slower beta line, and the two carry the same commits at different points on the maturity curve. The recent stream is maintenance-shaped: dependency security bumps in Mermaid and Electron, a journal lookup fix for trashed docs, retry handling for failed transcription jobs. The last directional move was workspace BYOK profiles with model catalogs and key rotation in early August, which sits on top of the MCP credential work from July.
◆ Where it's heading
Two threads run in parallel. The AI thread is about who supplies and controls the model - BYOK profiles, MCP credentials, access modes - rather than adding model features. The other thread is self-host ergonomics, and the Render blueprint is the clearest recent instance: AFFiNE keeps lowering the cost of running your own instance while keeping the AI layer pluggable. Between those, the canary absorbs a steady flow of upstream security patches with little product change attached.
◆ Prediction
Expect the self-host track to keep collecting deploy targets and the BYOK work to extend to more provider surfaces; on current cadence the next 0.27 beta will consolidate the canary work rather than introduce anything new.
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.
