Double vs SiYuan: at a glance
What is Double?
Double's AI assistant now reaches beyond the ledger through any MCP server.
Double is an accounting-practice platform built around QuickBooks Online, and its Ask Double assistant is now the center of the product. Recent releases opened Connectors to all users (Slack, Notion, HubSpot, Google and any MCP server), added a cheaper Standard model and Auto routing, and filled out invoicing, deposits and cash-flow reporting.
What is SiYuan?
SiYuan is turning its note app into an agent workspace that reads its own images and data.
SiYuan ships alpha builds almost daily. The 3.8.6 cycle made the app an agent host: OAuth 2.1 on the built-in MCP server, workspace AGENTS.md instructions, and Bazaar package management for agents. The 3.8.7 alphas have moved to content types: richer mind maps, database automations, a Tesseract/PaddleOCR choice for local OCR, and now AI OCR straight from the image menu.
Double vs SiYuan: editorial side-by-side
Double
6.3COLLAB
Double's AI assistant now reaches beyond the ledger through any MCP server.
◆ Current state
Double is an accounting-practice platform built around QuickBooks Online, and its Ask Double assistant is now the center of the product. Recent releases opened Connectors to all users (Slack, Notion, HubSpot, Google and any MCP server), added a cheaper Standard model and Auto routing, and filled out invoicing, deposits and cash-flow reporting.
◆ Where it's heading
Two tracks run in parallel: deeper QBO bookkeeping coverage (sales tax, Undeposited Funds, revenue-share allocations) and an AI layer that can act across a firm's whole toolset. Model tiering and a free Scale-features week show Double managing AI cost while pushing upgrades.
◆ Prediction
Expect Ask Double to start acting on connected tools rather than only reading from them, and continued QBO-first features that later reach other ledgers.
SiYuan
6.3COLLAB
SiYuan is turning its note app into an agent workspace that reads its own images and data.
◆ Current state
SiYuan ships alpha builds almost daily. The 3.8.6 cycle made the app an agent host: OAuth 2.1 on the built-in MCP server, workspace AGENTS.md instructions, and Bazaar package management for agents. The 3.8.7 alphas have moved to content types: richer mind maps, database automations, a Tesseract/PaddleOCR choice for local OCR, and now AI OCR straight from the image menu.
◆ Where it's heading
Two tracks run in parallel. One gives agents secured, configurable access to the workspace and its extensions; the other turns databases, mind maps and images into structured, searchable blocks. OCR in asset search plus AI OCR in the image menu means images are becoming queryable text, which is exactly the material an agent needs to work over.
◆ Prediction
Expect 3.8.7 to reach beta with the mind map, OCR and database automation work consolidated. The entries don't yet show whether agents can trigger or author those automations.
