AI Alt Text Writer Operation
Create captions for your images within Clairview Files with this custom operation, using Clarifai.
This operation requires two options to be set - first a personal access token from Clarifai (you can find this in your personal settings under Security), and a link to the image file. The operation will return a string containing a text that describes the image.
You can use the operation to then save the result to a file description or item, or run further automation on the output.
Output
This operation will output the text that was generated from the provided image:
"a photograph of a man standing in front of a large explosion of smoke"
Flow Setup
Automatically Write Alt Text For New Files
Create a Flow with an Event Hook action trigger and a scope of files.upload
. Use the AI Alt Text Writer operation, setting the File URL to https://your-clairview-project-url/assets/{{ $trigger.key }}
, being sure to provide your specific Clairview Project URL.
This will work if your file is public, but if it isn't, you can append ?access_token=token
to the File URL, replacing the value with a valid user token that has access to the file.
This operation will trigger on every new file upload, regardless of location or filetype. You may wish to add a conditional step between the trigger and transcription operation. The following condition rule will check that the file is an image:
{
"$trigger": {
"payload": {
"type": {
"_contains": "image"
}
}
}
}
Write Alt Text On-Demand
Create a Flow with a Manual trigger and select a collection with a file field, which should contain an image file. Set the Location to Item Page Only. To receive the file ID create a Read Data operation for the same collection, setting IDs to {{ $trigger.body.keys[0] }}
.
Use the AI Alt Text Writer operation, setting the File URL to https://your-clairview-project-url/assets/{{ $last.file_field_name }}
, being sure to provide your specific Clairview Project URL and file field name.
