Great tool for organising personal, chuck a bunch in a folder ask questions of the dataset instead of having to open each seperately when you need to narrow down specific entries.

Leonel Curra Dec 29, 2023 v@ initial release

Amazing, fast

Adrian Bedford Sep 29, 2023 v@ initial release

Skims (at best) the first 50 or so pages (at most). Absolutely nothing here you can't get from a free plugin to ChatGPT or as standard on Claude.

Gagandeep Singh Jun 10, 2023 v@ initial release

Works reasonably well for quickly reading Research Papers but need to ask questions about specific sections of research paper, if I ask questions which need to use info from different sections of the research paper then it doesn't work that well and don't provide accurate info.

I think that developer need to improve this.

Rehan Khan Jun 6, 2023 v@ initial release

Can not do even basic tasks of summarizing sections appearing in the pdf. I complained to the company and offered to refund my subscription.

Brandon Webb May 27, 2023 v@ initial release

It isn't as good as Chat GPT. you get a better response putting in portions of the pdf into chat gpt 4.
