Double vs PhotoPrism: at a glance
What is Double?
Ask Double can now read and post in Microsoft Teams on an accountant's behalf.
Double is an accounting-practice platform built around QuickBooks Online, with the Ask Double assistant at its centre. The October 22 release connects Ask Double to Microsoft Teams, where it can read chats and channels and send messages as the user after confirmation, and lets it draft executive summaries and act on batches of tasks. Bookkeeping work continues alongside: customer-level and whole-P&L allocations, partial fixed-asset disposals and reminders for every open client request. The week before brought Ask Double to Xero and Consolidations in beta.
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.

Ask Double can now read and post in Microsoft Teams on an accountant's behalf.
◆ Current state
Double is an accounting-practice platform built around QuickBooks Online, with the Ask Double assistant at its centre. The October 22 release connects Ask Double to Microsoft Teams, where it can read chats and channels and send messages as the user after confirmation, and lets it draft executive summaries and act on batches of tasks. Bookkeeping work continues alongside: customer-level and whole-P&L allocations, partial fixed-asset disposals and reminders for every open client request. The week before brought Ask Double to Xero and Consolidations in beta.
◆ Where it's heading
Two tracks run in parallel: fuller QBO bookkeeping coverage and an AI layer that reaches across a firm's tools. Teams is the first connector in these entries where Ask Double writes outside the ledger, not just reads, with a confirmation step as the guardrail. The assistant is becoming the way staff operate Double in bulk, from tasks to reports.
◆ Prediction
Expect more write-capable connectors with the same confirm-before-send pattern, and Ask Double on Xero gaining write actions after its read-only beta.
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.
