PhotoPrism vs Tana

PhotoPrism vs Tana: at a glance
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.
What is Tana?
Tana is building a meeting layer into its graph, and the AI now acts instead of asking.
Almost everything shipped since early July is about meetings: a pre-meeting hub card holding join, capture and RSVP-grouped attendees; an always-on-top nudge that now fires for internal Tana calls as well as Zoom, Meet and Teams; one-click conversion of a scheduled Tana call into an external audio capture; and meeting creation moved to the top of the Today page. Alongside it, meeting agents got an org-level voice picker with audition playback. The one non-meeting release lets the AI pin and unpin docs, spaces and agents directly, with no proposal to approve first.

PhotoPrism
3.8COLLAB
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.
Tana
6.3COLLAB
Tana is building a meeting layer into its graph, and the AI now acts instead of asking.
◆ Current state
Almost everything shipped since early July is about meetings: a pre-meeting hub card holding join, capture and RSVP-grouped attendees; an always-on-top nudge that now fires for internal Tana calls as well as Zoom, Meet and Teams; one-click conversion of a scheduled Tana call into an external audio capture; and meeting creation moved to the top of the Today page. Alongside it, meeting agents got an org-level voice picker with audition playback. The one non-meeting release lets the AI pin and unpin docs, spaces and agents directly, with no proposal to approve first.
◆ Where it's heading
Tana is moving from the place notes about meetings land to the place meetings happen. Each release closes another gap between the calendar event and the captured artifact, and the internal-meeting nudge shows Tana now hosts calls rather than only recording other people's. The pin change is small but points the same way on the agent side: the assistant is being trusted to execute rather than propose.
◆ Prediction
Expect the meeting surface to extend past the call itself into automatic post-meeting artifacts routed into the graph, and more AI actions that apply immediately rather than queuing a proposal.
