Can Dify turn a clean scan into accurate text?

Dify did not turn the clean scan into accurate text. The scan had no extractable text, yet the document was marked completed and available with a word count, and the lookup returned other records instead of the scan's fact; the Pipeline view was present but unopened.

Why this result

The run needed the fact to return, or a no-text message if it could not. Instead, the lookup missed the scan while the document still showed completed, available, and counted, so it does not meet the needed result.

Also observed on this row

Word count mask. The status surface reports 87 words for a chunk that is only an image link, so it looks searchable even though no transcript text is stored.

Pipeline left closed. The workspace included a Pipeline section, but it stayed unopened, matching the path used in this run.

Limitations of this result

The capture does not show the ingestion-time configuration.

Configuration and setup

How this tool was set up for the run and what the test needed in place. Each row is a fact from the run's records; a fact the records do not hold is left out, not guessed.

Set up before the run
A scan with no hidden text layer had to contain the fact only as pixels; the scan was ingested, then queried using the visible wording.

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.

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.
