A Modern Free Alternative to PDFaid
Editing, annotation, OCR, and conversion — with a smoother interface and built-in AI.
PDFaid offers a solid set of PDF utilities, but its editing surface and AI options are limited. CalculatorApp.me PDF Editor pairs the same editing, annotation, OCR, and conversion tools with a cleaner interface — hand/pan, Fit, Fullscreen — plus a free AI Summarizer and "Ask this PDF" assistant, with no watermark or signup.
