I have 3 options:
1. Add intent detection to the chat module, support both mind map generation with commands & retrieve information from the pdf in a same input box, which may increase the latency and take wrong actions.
2. Remove the chat with pdf feature and turn the product to mind map generation, which mignt strange because the product name is chatpapers.
3. Design a new product to focus on mind map generation, and keep this product as it is.
Which could be better? Or any other suggestions?
With a new product, you're still working out what aspects of it appeal to customers more than others.
My habit has been to find that out as quickly as possible, then focus the product to just do that as well as possible. If I were in your shoes, I'd focus like a laser on the mind maps. Once that's nailed down and polished, I'd consider bringing in the other aspects.
The advantage of doing this is twofold: by focusing on a single thing, you can really excel at that thing and attract more customers because it rocks so much. Then, once you have solid customer base, you have a receptive existing audience for expanded capabilities (and to guide you as to what form is best for those new capabilities).
In any event, no need to make drastic changes. Maybe idea 1, but definitely not wholesale changes like 2 and 3. There are plenty more options on the table, such as:
* make two submit buttons in chat area (chat vs mindmap)
* support very specific mindmap commands and use simple string matching for intent detection (not models)
* create a way for people to choose either chat or mindmap commands for the right hand sidebar
* add more example inputs (like the "show me a summary") to guide the users
* etc
I could literally see myself on the command line typing
pdf2mm -i report.pdf -o report.xml -f "sales, drivers"
where -f is a list of strings to direct focus (seed the "centre of the map")
Dump .xml or .opml
Get this right and you'd have no problem offering that as a paid Web service and throw the cmdline util out there for free please. :)
