OCR History
Every OCR run is recorded automatically. The OCR History Window (600 × 550, resizable) lets you revisit extracted text from earlier in the session — or, if history persistence is on, from earlier sessions.
Opening the Window
Click the text-extract history button in the MainWindow toolbar. It sits next to the capture-history button and uses a dedicated glyph so the two are easy to tell apart.
What Gets Stored
Each entry records:
| Field | Example |
|---|---|
| Timestamp | 2026-04-18 14:32:07 |
| Confidence | 94% |
| Processing time | 412 ms |
| Text preview | First ~100 characters of the extracted text. |
| Full text | Complete OCR output, shown on click. |
Items are listed in reverse chronological order. Click any row to expand the full text pane; from there a Copy button sends the text to the clipboard.
Typical Use
- Reviewing a session — "what was on that dialog I OCR'd twenty minutes ago?" Open the window, scroll back, copy.
- Comparing runs — Did preprocessing help? Run OCR with it on, then off, and compare confidence scores in the history list.
- Rebuilding lost clipboard — You OCR'd something, copied it, then overwrote your clipboard. The text is still here.
Tip — The history is separate from the capture history (07.02). Deleting a capture does not delete the OCR text extracted from it.
Linkage to Captures
When OCR is run on a capture that came from the main editor, the result is also attached to that capture's entry in the capture history (07.02). This means a single capture history row can carry its extracted text with it indefinitely.
