When to use OCR
OCR fits dynamic UIs where the text changes — ticket numbers, prices, status messages, balances — and pure image matching isn't enough.
Who it's for
Teams capturing or validating text in legacy apps, dashboards, or terminal-style UIs, especially when the value has to drive the next step of a workflow or stop the run cleanly.
Concrete scenario: TriggerFlow reads a shipment number from a desktop screen, stores it as
${shipment_id}, types it into a web portal, and stops the run the moment an OCR-captured status reads "cancelled".
How TriggerFlow uses OCR
Define an OCR region, pick text or number matching, set validation rules, and decide whether to trigger workflows, click on matches, or store values for later steps. Every OCR event is tied to a screenshot in the run history.
