Currently, Kagi Assistant only allows uploading a single document during thread creation. However, it would be useful to be able to upload extra documents after the thread was created.
It will vastly improve existing workflows. For example, users could upload a new document to a thread to provide more context or resources to answer questions.
I see users using the feature to compare different documents mid-conversation. For example, uploading one document to start, then asking to compare it to multiple others as the conversation continues.
Fastlane and ChatGPT allow uploading new content mid-conversation.
