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 Shiori?
A Go bookmark manager rebuilding itself around an API — and only ever shipping release candidates.
Shiori is a self-hosted read-later and bookmark tool whose recent history is entirely release candidates: v1.7.0-rc.2, rc.3, v1.7.2-rc.1, v1.8.0-rc.1. The visible work has moved off the web UI and into an API v1 surface — tag endpoints, bookmark-tag association, filtering and counts — plus infrastructure like proxy-header authentication and SQLite performance. The last tagged release in this window is from July 2025.
Contractbook vs Shiori: 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.
Shiori
0.0COLLAB
A Go bookmark manager rebuilding itself around an API — and only ever shipping release candidates.
◆ Current state
Shiori is a self-hosted read-later and bookmark tool whose recent history is entirely release candidates: v1.7.0-rc.2, rc.3, v1.7.2-rc.1, v1.8.0-rc.1. The visible work has moved off the web UI and into an API v1 surface — tag endpoints, bookmark-tag association, filtering and counts — plus infrastructure like proxy-header authentication and SQLite performance. The last tagged release in this window is from July 2025.
◆ Where it's heading
The project is converting from a web app with an API bolted on into an API-first service with a client, and the login component, PWA and theme work are being rewritten around that split. Proxy forward-header authentication in particular is a deployment-shape decision: it assumes Shiori sits behind an authenticating reverse proxy rather than owning identity itself. The RC-only tagging pattern makes it hard to tell what the maintainers consider stable.
◆ Prediction
The next step is presumably a final v1.8.0 consolidating the API v1 tag work, though nothing in these entries indicates the RC-to-stable promotion is scheduled. If the pattern holds, the following RC continues on API endpoints rather than the UI.
