I've added all suggestions from entire thread to my log and will prioritize implementing them.
Regarding pricing, I don't know offering a free tier is right approach or not .. I believe that the queries are complex and long. not sure they could be shared among users. Anyways, for next 2 or 3 months its going to be beta. my current focus is adding value, will ask the users about pricing later. Note that, for each question, it crawls 10-15 pages, or even more if you ask to enrich a table. there is LLM cost, now a days webpages are really huge.
Thank you again for your input and support. Please let me know if you have any other thoughts or questions.
