Ever since ChatGPT came into existence, AI tools have been taking the spotlight. But it's not limited to chatting with a bot anymore.
AI technology has got a new trick: Chat with Docs.
Let's take an example. You're facing a document or a lengthy, complex research paper. You want information real quick, but you don't have time to read the document line by line. What if we say you can outsource the task to a chat with Docs tool instead?
With the rise of such AI-powered tools like Knolli and more, you can delve deeper into multi-format files, pulling out relevant information in a matter of seconds. No more time suck on endless search or scrolling.
These numbers speak for themselves.
According to Fortune Business Insights, the North American IDP market size is expected to reach $66.68 billion by 2032.
Even most advisors use multiple document processing software in combination with one another to save hours and boost productivity.
Dealing with long, complex Docs and PDFs that require continuous scrolling and endless searching can be frustrating. But chatting with your docs using AI makes it easier to find the information you need quickly and efficiently.
But now it's time to think how you'd save time gathering information while boosting productivity. Would you use AI or not?
