What is PhotoPrism?

PhotoPrism now lets AI assistants search your photo library over MCP.

PhotoPrism's 29 October release adds OAuth for outside apps and MCP tools so AI assistants can search and browse a library within account permissions, enabled by default and switchable per account. It also adds experimental PostgreSQL support with a database transfer command and an export dialog. September brought new face detection and embedding models plus private and hidden people; October 7 moved classification and NSFW detection to ONNX with GPU support and dropped custom TensorFlow models.

What is SiYuan?

SiYuan 3.8.11 alphas add freeform mind maps and plugin snapshots right after 3.8.10.

SiYuan pushed 3.8.10 through betas and release candidates between November 7 and 9, carrying workspace AI memory, database sub-items and a built-in Markdown editor. The 3.8.11 alphas followed within days: freeform mind map relationships with per-node connector styles, browsing and restoring plugin snapshots, excluding assets from cleanup, a built-in date picker and rich text in database primary keys. Alpha 4 adds search and replace in the standalone Markdown editor.

PhotoPrism vs SiYuan: editorial side-by-side

P6.3

PhotoPrism now lets AI assistants search your photo library over MCP.

◆ Current state

PhotoPrism's 29 October release adds OAuth for outside apps and MCP tools so AI assistants can search and browse a library within account permissions, enabled by default and switchable per account. It also adds experimental PostgreSQL support with a database transfer command and an export dialog. September brought new face detection and embedding models plus private and hidden people; October 7 moved classification and NSFW detection to ONNX with GPU support and dropped custom TensorFlow models.

◆ Where it's heading

The vision stack is now fully ONNX and GPU-capable, and the library itself is becoming something other tools can query. PostgreSQL support breaks the long MariaDB/SQLite limit for larger installs.

◆ Prediction

PostgreSQL leaving experimental status and MCP gaining more than read-only search are the likely next steps, given both arrived in first form here.

5.0

SiYuan 3.8.11 alphas add freeform mind maps and plugin snapshots right after 3.8.10.

◆ Current state

SiYuan pushed 3.8.10 through betas and release candidates between November 7 and 9, carrying workspace AI memory, database sub-items and a built-in Markdown editor. The 3.8.11 alphas followed within days: freeform mind map relationships with per-node connector styles, browsing and restoring plugin snapshots, excluding assets from cleanup, a built-in date picker and rich text in database primary keys. Alpha 4 adds search and replace in the standalone Markdown editor.

◆ Where it's heading

SiYuan works in fast public cycles, with the next version's alphas starting as soon as the last one stabilises. 3.8.11 is about polish and editing depth: mind maps, databases and the new Markdown editor all get more control.

◆ Prediction

Expect more 3.8.11 alphas, then betas and release candidates with the same list, following the 3.8.10 pattern.
