Double vs SiYuan
A side-by-side editorial comparison of Double and SiYuan — release velocity, themes, recent moves, and the top alternatives to consider.
Double vs SiYuan: at a glance
What is Double?
Double moves Ask Double from a chat box to agents that run on a schedule.
Double is an accounting practice platform whose product surface is increasingly reached through Ask Double, its assistant. Over the last two months Ask Double has absorbed transaction creation and editing, live spreadsheets, metrics setup, accrual and workpaper preparation, voice input, and reads from Slack, Notion and HubSpot. The August 20 release adds bank-transaction import from a CSV, PDF or image, and opens a private beta for custom AI agents that run on a schedule or event trigger.
What is SiYuan?
SiYuan opens 3.8.2 by decoupling agent sessions and opening the plugin event bus
SiYuan is two days past the 3.8.1 stable that closed a seven-build beta run, and has already opened 3.8.2 with an alpha. The agent surface introduced in the 3.8.0 line is now the product's centre of gravity: this alpha gives each agent session independent execution and repairs tag rendering and malformed tool arguments in agent responses. Alongside that, the plugin event bus gains interception points for asset uploads and link opening, and the package marketplace reaches mobile.

Double moves Ask Double from a chat box to agents that run on a schedule.
◆ Current state
Double is an accounting practice platform whose product surface is increasingly reached through Ask Double, its assistant. Over the last two months Ask Double has absorbed transaction creation and editing, live spreadsheets, metrics setup, accrual and workpaper preparation, voice input, and reads from Slack, Notion and HubSpot. The August 20 release adds bank-transaction import from a CSV, PDF or image, and opens a private beta for custom AI agents that run on a schedule or event trigger.
◆ Where it's heading
The arc is a steady transfer of the product's own features into the assistant, and it has now crossed from assistance into delegation. Every prior step still required an accountant to sit in the chat and ask; scheduled agents that hand work back for human review do not. The surrounding release notes are consistent with that reading — permissions, visibility defaults, deep links, and credit-spend reporting per user are the plumbing a firm needs before it lets software act unattended across a client book.
◆ Prediction
Expect the agents beta to graduate with per-client scoping and an approval queue, following the read/write split already used for Connections, and expect agent runs to be metered against the AI credits Double now sells.

SiYuan opens 3.8.2 by decoupling agent sessions and opening the plugin event bus
◆ Current state
SiYuan is two days past the 3.8.1 stable that closed a seven-build beta run, and has already opened 3.8.2 with an alpha. The agent surface introduced in the 3.8.0 line is now the product's centre of gravity: this alpha gives each agent session independent execution and repairs tag rendering and malformed tool arguments in agent responses. Alongside that, the plugin event bus gains interception points for asset uploads and link opening, and the package marketplace reaches mobile.
◆ Where it's heading
The pattern across 3.8.0 and 3.8.1 was to open a capability and then spend a long beta run hardening it; 3.8.2 is starting the same way, broad rather than deep. Mobile carries the volume this cycle - marketplace support, drag-and-drop and selection repairs, and workspace deletion all land there. Extensibility is the quieter thread: letting plugins intercept uploads and hyperlinks turns the event bus from a notification channel into a control point.
◆ Prediction
Expect a 3.8.2 beta run that stabilises the mobile marketplace and the new plugin interception hooks rather than adding further capability. Whether independent agent sessions grow into more than parallel execution is not readable from this alpha.
