Blueberry Shake is a browser-based PDF editor that performs deterministic editing of text and scanned documents entirely client-side, using OCR and font reconstruction without generative AI. It stands out for its privacy-first, no-upload approach and its ability to truly edit PDFs rather than just overlay annotations.
