Looking for feedback on free website that helps researchers find systematic review or meta-analysis topics

Looking for brutal feedback on a free tool I built to help researchers figure out if a systematic review is worth doing.

It's called Blindspot. The core idea: before you commit to a systematic review, you should know (a) how much primary literature actually exists, (b) whether someone already did this review, and (c) where the real gaps are.

It searches PubMed, OpenAlex, and Europe PMC, gives you a feasibility score using Gemini. If your topic comes back insufficient, it suggests alternative topics in the same research area that do have enough studies.

It's not trying to replace Covidence. It's for the "should I even start this review?" question, which I felt was underserved.

Would genuinely appreciate feedback from anyone who's done systematic reviews.

I know that the feasibility scoring is not well calibrated, but I am looking to improve it by incorporating more data. Also, trying to figure out whether the gap suggestions are useful or just AI word salad.
