Check progress

Select a pilot annotator, then load by UTC date range (last-changed day) — or type a page ID and press Enter (dates not required).

Browse all uses the header language. Set a UTC day to list every annotation saved that day (saved_at date part; time ignored). Optionally restrict by annotator email. Optionally check feedback tags below to keep only rows that include at least one of the selected options (page, line, or manual — combined as OR). Leave tags unchecked to not filter by feedback.

Optional feedback filter — rows must match any checked tag or any checked “Other” rule (OR). Text in Other is not matched; we only test that it is non-empty.
