Discourse forums now have a URL for finding post with a prompt as an argument.
The endpoint:
https://SITENAME/discourse-ai/embeddings/semantic-search.json?hyde=false&q=YOURQUERY
Will perform a vector similarity search.
Here is an example URL using this forum
It seems that the argument YOURQUERY will accept a prompt such as that given to ChatGPT (only tried simple single sentences so far).
The result is in JSON which while may sound like it is less useful to the blind it actually is of more use in that the JSON can be more easily incorporated into other technologies, in other words one does not have to parse an HTML page to get the relevant information.
