Double vs Readarr: at a glance
What is Double?
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.
What is Readarr?
Six releases of small fixes and translations, then nothing since June 2025.
Readarr's last six entries run from March to June 2025 and are uniformly small: a truncated root-folder path, remote image links for posters and covers, NLog message templating, disabled SelectInput options, Weblate translation batches. Every entry opens with the same instructions about switching to the develop branch and not updating inside a running Docker container. Nothing in this window adds capability, and no entry has appeared in over a year.

Double is turning its accounting assistant into the way the work gets done
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Readarr
0.0COLLAB
Six releases of small fixes and translations, then nothing since June 2025.
◆ Current state
Readarr's last six entries run from March to June 2025 and are uniformly small: a truncated root-folder path, remote image links for posters and covers, NLog message templating, disabled SelectInput options, Weblate translation batches. Every entry opens with the same instructions about switching to the develop branch and not updating inside a running Docker container. Nothing in this window adds capability, and no entry has appeared in over a year.
◆ Where it's heading
The pattern is a project in caretaker mode: auto-generated commit lists, incremental UI corrections, and internal work like using ReflectionOnly types to avoid loading assemblies unnecessarily. Volume held steady at roughly one release every one to two weeks until it stopped entirely. The entries themselves give no reason for the halt.
◆ Prediction
The changelog offers no signal of resumed development; without new entries there is nothing here to project forward beyond the fact that the feed went quiet after 0.4.18.
