What is Memos?

Memos adopts calendar versions and rebuilds writing around one block editor.

Memos has moved to calendar versioning, with 26.10 candidates following 0.31 and versions now written YY.MM.N. 26.10.0-rc.2 replaces the editor with one block editor shared by writing and reading, and turns the instance-wide memo length and upload caps into ordered per-user usage limits that also cover memo count and total storage. rc.1 added editor suggestions and transcription of existing audio attachments, and Spaces now follow the user across Timeline, Calendar, Map and Attachments.

What is PhotoPrism?

PhotoPrism swapped in an ONNX vision pipeline, then opened the library to 360° media at 16K.

Two substantial releases in ten weeks moved the product on both axes it cares about. May replaced the legacy Pigo face detector entirely with an ONNX-based pipeline, made vision.yml accept model identifiers from Hugging Face, Ollama and OpenAI-compatible catalogs, and modernised media handling with Vulkan transcoding, a native HEIC/AVIF reader and layered TIFF and PSD support. July added interactive equirectangular 360° photos and video, raised the thumbnail and video ceiling to 16K, and put an inline multi-page PDF viewer in the app.

Memos vs PhotoPrism: editorial side-by-side

M
Memos
COLLAB
5.0

Memos adopts calendar versions and rebuilds writing around one block editor.

◆ Current state

Memos has moved to calendar versioning, with 26.10 candidates following 0.31 and versions now written YY.MM.N. 26.10.0-rc.2 replaces the editor with one block editor shared by writing and reading, and turns the instance-wide memo length and upload caps into ordered per-user usage limits that also cover memo count and total storage. rc.1 added editor suggestions and transcription of existing audio attachments, and Spaces now follow the user across Timeline, Calendar, Map and Attachments.

◆ Where it's heading

Spaces made Memos multi-user, and usage limits are what an administrator needs once several people share an instance. The candidate keeps spending compatibility to get there: upgrading signs everyone out because access tokens are bound to the password, and the old size settings are removed without migration, leaving defaults of 8 KiB per memo and 32 MiB per file. The HTTP layer also moved to the Go standard library, with operators asked to report reverse-proxy differences.

◆ Prediction

Expect 26.10.0 stable with those upgrade notes intact. Reverse-proxy reports against the new HTTP layer are the likeliest cause of another candidate.

P3.8

PhotoPrism swapped in an ONNX vision pipeline, then opened the library to 360° media at 16K.

◆ Current state

Two substantial releases in ten weeks moved the product on both axes it cares about. May replaced the legacy Pigo face detector entirely with an ONNX-based pipeline, made vision.yml accept model identifiers from Hugging Face, Ollama and OpenAI-compatible catalogs, and modernised media handling with Vulkan transcoding, a native HEIC/AVIF reader and layered TIFF and PSD support. July added interactive equirectangular 360° photos and video, raised the thumbnail and video ceiling to 16K, and put an inline multi-page PDF viewer in the app.

◆ Where it's heading

The AI work has moved from bundled TensorFlow models to a pluggable pipeline where the model catalog is configuration, not a build artifact — Ollama, OpenAI and Hugging Face identifiers all resolve through the same file. In parallel the media layer keeps absorbing formats other libraries push out to external tools: PSD, layered TIFF, PDF, and now 360°. PhotoPrism is positioning as the thing you point at a mixed archive, not just a photo folder.

◆ Prediction

Expect the format expansion to continue and the vision configuration to keep broadening its provider surface, with the accessibility section added in July likely to grow into a fuller pass.
