Documentation for the decisions the tool cannot make: choosing evidence, understanding source limits and knowing when professional review is required.

Common tasks

Where is my research saved?

Choose Save changes in the workspace. Files are stored only in this browser on this device, not in an account or cloud service. Clearing browser data removes them.

Open My research →
How do I reopen or update a file?

Open My research and select your file. It opens the saved source snapshot, not a new search. Use Check for newer records to review differences, choose whether to adopt the new snapshot, then save. Missing selections are flagged, not silently removed. Older files without a snapshot ask before retrieving current records.

How do I share a report or spreadsheet?

Open Report, then Print / Save as PDF. Download sales CSV (Excel) exports the full filtered sales list, including source links and selection flags. These readable exports do not restore editable files on another device.

What if saving fails?

Stay on the page. Your working edits remain visible; the app does not report success or replace unreadable stored data. Print a PDF from Report and export sales as CSV before leaving. Check browser storage settings; do not clear existing data to fix a read error.
