CommaFeed is patching its way through the attack surface a self-hosted reader inherits
A side-by-side editorial comparison of Double and Tana — release velocity, themes, recent moves, and the top alternatives to consider.
Double is turning its accounting assistant into the way the work gets done
Double ships weekly, and nearly every release extends Ask Double rather than the surrounding application. In the last two months it has learned to build workpapers by reconciling accounts against supporting documents, import accruals, create and manage client metrics through the MCP and API, take voice input, and — in private beta — reach into Slack, Notion, and HubSpot. The non-assistant work fills in what firms need to trust that: role-based restrictions on editing client properties, and check transactions in AI Transactions.
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.

The assistant is moving from answering questions to performing the billable work — tie-out, accrual setup, metric standardization across a whole book of clients. Each release pairs that with an access or permissions control, which is the pattern of a vendor that knows the objection is liability rather than capability. The accounting engine itself keeps advancing underneath, most recently with prepaid contracts paid in installments.
Given the review-and-signoff question these features raise, the likely next step is an approval or audit trail around what Ask Double produces rather than another task it can perform.

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.
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.
