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 Readwise?

Readwise launches Books, its own ebook store and reading app, a week after unbundling.

Readwise now sells three products. A week after splitting Reader and Highlights into separate plans, it launched Readwise Books on October 30: an iOS and Android ebook store and reading app stocked by the major publishers, with reading sessions, following other readers, and Kindle and Goodreads imports. The same release added 13 Books tools to the Readwise MCP server, moved podcast transcripts onto the YouTube cleanup pipeline, and lets the Reader API set reading progress.

PhotoPrism vs Readwise: 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.

6.3

Readwise launches Books, its own ebook store and reading app, a week after unbundling.

◆ Current state

Readwise now sells three products. A week after splitting Reader and Highlights into separate plans, it launched Readwise Books on October 30: an iOS and Android ebook store and reading app stocked by the major publishers, with reading sessions, following other readers, and Kindle and Goodreads imports. The same release added 13 Books tools to the Readwise MCP server, moved podcast transcripts onto the YouTube cleanup pipeline, and lets the Reader API set reading progress.

◆ Where it's heading

Readwise is moving from a layer on top of other people's reading apps to owning the purchase and the reading itself. The unbundle, the free Books app and the shared MCP server point to separate entry products that all feed the same account. Reader keeps its weekly cadence of TTS, transcript and parsing work underneath.

◆ Prediction

Expect weekly Books fixes and Kindle-import work, and a move from invite-only to open signup if the store holds up.
