Nice project for looking for pitchdeck references. Thanks for building and sharing it. I am curious about the tech behind it - are you doing OCR on images? The search is very responsive - it's definitely not elastic search, curious what index/search system are you using?

You might enjoy the blog post[0] (150GB of images, tesseract OCR, 2GB of data, Algolia for search). There's a github repo too[1]

Glad it helps! There are 4 key steps that I took:
- Upscaling (using Upscayl[0])
- OCR (using tesseract[1])
- Indexing (using Algolia[2])
- Scaling the processing and running on AWS (Klotho[3] - our startup)
I wrote a more in-depth blog post about it[4]
