The layout

The viewer has three regions:

• A vertical toolbar down the left edge — one icon per panel.
• The canvas in the middle — the grid (or scatter, map, etc.).
• The Inspector on the right — opens when you click an image.

The viewer in its default grid view. The left toolbar. Each icon toggles a panel; badges show active filter and selection counts.

Moving around

• Pan by dragging the canvas; zoom with the scroll wheel or trackpad pinch.
• Press a tile to focus it (opens the Inspector); arrow keys then move focus tile-to-tile, Enter zooms in, Escape resets.
• The grid handles very large collections — hundreds of thousands of images — by streaming tiles as you move.

View types

Open the Views panel from the toolbar to switch how the data is drawn. The same panel carries the controls shared across views — Sort by (column + direction), Colour by (heatmap a numeric column: TDA, visual features, or any of your own), and Outlier detection.

The Views panel: pick a view type, then a column to sort and one to colour by.

Grid

The default. Every image is a tile; pan and zoom to scan the whole collection and spot visual patterns. Sorting and colouring reflow the tiles.

Table

A spreadsheet of the metadata — sortable, resizable columns with virtual scrolling so it stays smooth on collections with millions of rows. Best when you want to read or compare the values behind the images.

Table view — the metadata behind every image, with sortable columns.

Scatter

Plots each image by two numeric columns (2D) or three (3D), with axis selectors on the canvas. Point it at a UMAP embedding (turn it on in Processing & analysis) and visually similar images cluster together.

Scatter view over a UMAP embedding — similar artifacts cluster, outliers sit apart.

Graph

Bins images into columns by a chosen field and stacks them by count — a quick distribution / relationship view across a category.

Graph view — images grouped and stacked by a column.

Map

Places images on a world map by latitude/longitude columns. Collections without geo data show the map without points.

Map view — for collections with location columns; pan and zoom like any web map.

Computed columns and outliers

Two collapsible sections at the foot of the Views panel extend what you can sort, colour, and filter by:

• Calculated Columns — derive a new column from a SQL expression over the existing ones (e.g. width_cm / height_cm for an aspect ratio). Once added, it behaves like any other column — sort it, colour by it, filter on it.
• Outlier Detection — score how unusual each image is and highlight the outliers, useful for spotting mislabelled or anomalous items.

Calculated Columns — define a column from a SQL expression; Outlier Detection sits just above.

Selecting images

• Click selects a single image (and focuses it).
• Ctrl/Cmd-click adds to the selection; Shift-click extends a range.
• The Selection panel lists what’s selected and offers batch actions; the toolbar badge shows the count.
• Selections feed straight into Export — see below.

The Inspector

Clicking an image opens the Inspector on the right:

The Inspector's Information tab — image preview, attribution, tags, and every metadata field.

• Information — the image preview, all metadata fields, tags (add/remove), and source attribution / citation.
• Annotations — drawing tools, classes, and image adjustments. See Annotations.
• Similar — visually similar images by CLIP similarity (when the collection has embeddings). See Filtering & search.

Video and PDF. When an item is a video or a multi-page PDF, the preview adapts: videos play with native controls, and PDFs get page navigation so you can flip through pages without leaving the viewer.

Saved views

Spent time setting up a view (mode, filters, axes, colour)? The Saved views panel stores it so you — or anyone you share with — can reload that exact state later.

Saved views — store a view's full state (mode, filters, axes) and reload it in one click.

Export

The Export panel turns the whole collection — or just your current selection — into a CSV/JSON, an image ZIP, a PDF, or W3C annotations. See Exporting for the full rundown.

Keyboard shortcuts

The viewer is keyboard-driven. Press ? at any time for the full overlay; the essentials:
