What is Tana?
The knowledge graph quietly turned itself into a meetings product.
Every release in this window touches meetings. Tana added a pre-meeting hub card, an always-on-top join nudge for internal calls, one-click conversion of a scheduled call into an external capture, a Present palette in the call toolbar, a voice picker for meeting agents, and action cards on Today for starting, scheduling or capturing a meeting. The AI work runs alongside it — chat that costs fewer tokens for the same quality, and an assistant that can pin things or hand you a shareable link to a document it referenced.
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.
Tana vs Contractbook: editorial side-by-side
Tana
6.3COLLAB
The knowledge graph quietly turned itself into a meetings product.
◆ Current state
Every release in this window touches meetings. Tana added a pre-meeting hub card, an always-on-top join nudge for internal calls, one-click conversion of a scheduled call into an external capture, a Present palette in the call toolbar, a voice picker for meeting agents, and action cards on Today for starting, scheduling or capturing a meeting. The AI work runs alongside it — chat that costs fewer tokens for the same quality, and an assistant that can pin things or hand you a shareable link to a document it referenced.
◆ Where it's heading
Tana is moving from a tool that stores what happened in a meeting to one that runs the meeting. Native Tana calls are now the default path on Today, with Zoom, Meet and Teams demoted to a capture case handled through desktop audio. The agent work points the same way: voices for meeting agents, AI that acts immediately rather than proposing changes for approval. The graph is becoming the substrate rather than the interface.
◆ Prediction
Given the pace of meeting-surface work and the AI moving from proposals to direct action, the next step is most likely deepening what agents can do during a live call. Nothing in these entries indicates how the token optimisation affects the underlying usage limits.
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.
