What is Paperless-ngx?

Paperless-ngx v3.1 ships AI document metadata automation as a hands-off workflow action

Paperless-ngx completed a major version cycle: v3.0.0 introduced breaking changes (positional argument removal, architectural cleanup) and v3.1.0 built on that foundation with an AI suggestions workflow action — the ability to apply AI-generated document metadata automatically as part of a workflow, rather than surfacing suggestions for manual approval. The 3.1.x patch series is now stabilizing: v3.1.2 addressed a security vulnerability, v3.1.3 resolved UI regressions.

What is SiYuan?

SiYuan is adding mind map block types and calendar scheduling depth as it pushes toward 3.8.6.

SiYuan is a local-first personal knowledge management tool in rapid alpha/beta iteration. The 3.8.6 alpha cycle introduces dedicated mind map and mind map item block types as first-class primitives, expanded calendar views with ISO week numbers and inbox scheduling, JavaScript embed support in image and PDF exports, and workspace storage statistics. The product ships multiple alpha builds per day and is clearly in a feature-accumulation phase before a stable release.

Paperless-ngx vs SiYuan: editorial side-by-side

P6.3

Paperless-ngx v3.1 ships AI document metadata automation as a hands-off workflow action

◆ Current state

Paperless-ngx completed a major version cycle: v3.0.0 introduced breaking changes (positional argument removal, architectural cleanup) and v3.1.0 built on that foundation with an AI suggestions workflow action — the ability to apply AI-generated document metadata automatically as part of a workflow, rather than surfacing suggestions for manual approval. The 3.1.x patch series is now stabilizing: v3.1.2 addressed a security vulnerability, v3.1.3 resolved UI regressions.

◆ Where it's heading

The AI suggestions workflow action is the headline direction — it moves document processing from assistant (AI suggests, human approves) to automation (AI applies metadata automatically based on workflow conditions). For document management, this is the meaningful step toward hands-off filing. The major version cycle also cleaned up legacy interfaces, reducing future maintenance burden.

◆ Prediction

The next release cycle will likely expand what AI suggestions can target — confidence thresholds for auto-apply, more metadata fields (tags, correspondents, document types), or integration with custom field sets. A configurable trust threshold that requires human review for low-confidence suggestions and auto-applies high-confidence ones would be the natural next increment.

6.3

SiYuan is adding mind map block types and calendar scheduling depth as it pushes toward 3.8.6.

◆ Current state

SiYuan is a local-first personal knowledge management tool in rapid alpha/beta iteration. The 3.8.6 alpha cycle introduces dedicated mind map and mind map item block types as first-class primitives, expanded calendar views with ISO week numbers and inbox scheduling, JavaScript embed support in image and PDF exports, and workspace storage statistics. The product ships multiple alpha builds per day and is clearly in a feature-accumulation phase before a stable release.

◆ Where it's heading

SiYuan continues deepening its block-based model by adding new primitive types — mind maps are the latest addition to a growing set that already includes databases, calendars, and embed blocks. Each new primitive adds interoperability complexity; the concurrent improvements to backlink display, reference sorting, and transitive link traversal suggest an underlying effort to make cross-block navigation coherent as the graph grows. The AI agent is also receiving model integrations (TypeSafe System One for decision modeling).

◆ Prediction

The 3.8.5 and 3.8.6 lines will merge into a stable release soon. The AI agent model integration and decision-model support suggest a near-term push to make the AI layer genuinely useful for structured knowledge work, not just Q&A over notes.
