Nuclino vs SiYuan: at a glance
What is Nuclino?
Nuclino ships its MCP server in January 2026, making the team knowledge base queryable by AI agents—a directional move toward AI-native knowledge management.
Nuclino is a collaborative knowledge management and wiki platform competing in the Notion/Confluence tier for teams that prioritize simplicity. The product has shipped its MCP Server (January 2026) and iterated on it (July 2026), making the entire knowledge base readable and writable by AI assistants. Alongside MCP, Nuclino has been steadily improving its Canvas (visual collaboration), search performance, workspace publishing, and its AI assistant Sidekick.
What is SiYuan?
SiYuan v3.8.4 beta cycle adds agent-controlled database fields, MiniMax image gen, and skill file management
SiYuan is deep in the v3.8.4 pre-release cycle, now at beta.4, shipping a dense stream of enhancements across each daily build. The defining theme of this release cycle is agent-control expansion: the AI can now configure database fields, manage skill files, stream Markdown previews, and use custom AI provider headers — moving SiYuan from a tool where AI assists with writing to one where AI can reshape the workspace structure itself. Mobile UX and PDF annotation improvements are running in parallel.

Nuclino
0.0COLLAB
Nuclino ships its MCP server in January 2026, making the team knowledge base queryable by AI agents—a directional move toward AI-native knowledge management.
◆ Current state
Nuclino is a collaborative knowledge management and wiki platform competing in the Notion/Confluence tier for teams that prioritize simplicity. The product has shipped its MCP Server (January 2026) and iterated on it (July 2026), making the entire knowledge base readable and writable by AI assistants. Alongside MCP, Nuclino has been steadily improving its Canvas (visual collaboration), search performance, workspace publishing, and its AI assistant Sidekick.
◆ Where it's heading
Nuclino is converging on AI-native knowledge management: the MCP server turns the wiki into an AI-queryable data source, Sidekick provides in-product AI assistance, and workspace publishing opens knowledge externally. The product is moving from 'team wiki' to 'knowledge infrastructure'—a surface that humans and AI agents can both read and write. The pace is quarterly, not weekly, which positions Nuclino as a deliberate mover rather than a rapid shipper.
◆ Prediction
The next move is likely deeper Sidekick integration—using the MCP layer to let the AI assistant answer questions by querying the knowledge graph directly, rather than relying on in-context retrieval. 2FA enforcement (April 2026) also signals growing enterprise attention.

SiYuan v3.8.4 beta cycle adds agent-controlled database fields, MiniMax image gen, and skill file management
◆ Current state
SiYuan is deep in the v3.8.4 pre-release cycle, now at beta.4, shipping a dense stream of enhancements across each daily build. The defining theme of this release cycle is agent-control expansion: the AI can now configure database fields, manage skill files, stream Markdown previews, and use custom AI provider headers — moving SiYuan from a tool where AI assists with writing to one where AI can reshape the workspace structure itself. Mobile UX and PDF annotation improvements are running in parallel.
◆ Where it's heading
SiYuan is building toward an agent-orchestrated personal knowledge base, where the AI layer can modify not just content but the organizational schema. The skill file management system suggests an emerging plugin-like architecture for agent behaviors. As multimodal generation (MiniMax image support) gets wired in, SiYuan's trajectory is toward a locally-run AI workspace that rivals cloud-based tools without the data-residency trade-off.
◆ Prediction
v3.8.4 stable will ship soon given the move to beta.4. The agentic features (database field configuration, skill management) will attract integrations from local-first AI workflow builders. Expect MiniMax and other provider integrations to expand in the next cycle.
