Can Reducto read a cleanly scanned document accurately?

Reducto accurately recovered the visible text from a cleanly scanned document. The scan’s text matched the output field by field, with the handwritten signature left as a <signature> placeholder and only two middle-dot separators dropped from the letterhead and footer lines.

## Certificate of analysis

Dear Ms Sandiman

Thank you for the four water samples delivered to this laboratory on 28 January 2026. They were booked in as batch KAL-11938 and analysed by the methods shown. The results below relate only to the samples as received.

Sampling point: Vardenne Channel, station VQ1
Date and time of sampling: 27 January 2026, 09:40
Total suspended solids: 41.6 mg/l (method KAL-M04)
Chloride: 18,200 mg/l (method KAL-M11)
Ammoniacal nitrogen: 0.42 mg/l (method KAL-M12)
Dissolved organic carbon: 5.9 mg/l (method KAL-M22)

The suspended solids figure is higher than those reported for this station in December and January, which were both below 30 mg/l. The samples were taken on the ebb, two days after the last placement at Kellow Sands, and the result is consistent with that.

The remaining samples will be held until 4 March 2026 and destroyed after that date unless you ask us to keep them.

Yours sincerely

Expected vs. Found
What this scenario evaluates

These are scenario-level criteria. Each test case's Expected and Found are listed separately.

  • Whether the visible text from the scanned page is recovered accurately.
  • Whether the page is not silently skipped or treated as empty because no text layer exists.
  • Whether the output stays faithful to the visible content without inventing text.
  • Whether scanned pages are handled as real input, not hidden by omission.
How this scenario is judged →
✓Found: Visible text was recovered accurately, including every field and numeric value.
Why this result

Visible text was recovered accurately from the scanned page, including the letterhead, all six result rows, and the closing details. The only differences were two dropped middle-dot separators, and the unreadable signature was handled with a placeholder.

Also observed on this row

Signature left as placeholder. The signature area has no readable letters, so the output uses a <signature> placeholder instead of guessing a name.

Middle dots dropped in headers. The missing middle-dot separators appear only in the contact and registration lines, not in the results block.

How this scenario is graded

How we decide Pass, Fail and Not gradable. The same rules apply to every tool tested on this scenario.

How results are decided

Each test case gets one result per tool: Pass, Fail or Not gradable. A test case we haven't run yet shows Untested. There are no partial results.

The rules
  • Pass: the tool did everything the test expected, and nothing it said contradicts the correct answer.
  • Fail: at least one expected behaviour clearly didn't happen; the row says which and quotes the tool.
  • Not gradable: our evidence couldn't settle the outcome (for example a record we needed is missing). It is never counted as a fail, and the row says what's missing.

Where this sits in the benchmark

This page is one cell of a larger study: one tool, one scenario. Only this benchmark's frame appears here.

History of this result

What has happened to this result since it was first published. Runs and grades are never overwritten: a retest or a re-grade publishes a new result and keeps the earlier one readable.

Act on this result

Nothing filed here edits the run or the grade. A challenge opens a review, and a review can produce a new run or a re-grade — which becomes the current result and leaves this one in the history.

This matches what I see

You run the same kind of test against your own setup and get the same behaviour.
