A few things to know before you start

Run the EXE. Both applications are portable for 64-bit Windows 10 and 11. No additional runtime is needed. Close the window to keep the app in the system tray; use Quit to exit.

Your data stays local. Notes are stored unencrypted in each app's Windows local-data folder. The browser board and desktop apps keep separate collections; they do not sync automatically.

Space for the original images. Full-resolution scientific imagery is embedded for offline use. Avenrift includes two plates; Isovela includes one. Allow about 2 GB of free memory when opening large images.

Quiet by design. Both apps are silent. English, Spanish and German follow Windows, with English for other interface languages. Date, time and timezone follow your computer. Avenrift contacts official feeds when you refresh or enable hourly checks. Isovela works fully offline.

Image-study limits. Isovela opens images up to 200 MiB, 150 megapixels and 20,000 pixels per side. TIFF uses its first frame. Crops are limited to 25 megapixels. Source images are never changed.

Different stories.
A shared question.

Choose where two stories meet. Read the evidence, then add a connection of your own. Your notes stay in this browser.

The same grid, one pair at a time.

Story A

Story B

Editorial = sourced connectionPersonal note = your saved words

Choose one story on each axis. The connection panel below updates for that pair.

Select a cell. Tab to move between cells; arrow keys move within the grid. Mirrored cells represent the same pair.

About this board and your browser storage

Saved story IDs and your connection notes are stored in localStorage for rosennavideo.com in the current browser. There is no account, server-side collection or cross-device sync. Clearing site data removes this collection; private browsing may remove it when the session ends.

The example does not save anything until you select Add these stories to my board. Personal notes belong to an unordered pair: A × B and B × A show the same note. Removing a story hides its connections but keeps its notes, so saving the story again restores them. Delete an individual note to remove it permanently.

A draft remains in this tab while you switch cells or views. Select Save note to keep it after reload; unsaved drafts are lost when you leave or reload the page. Stored references do not download articles for offline reading.
