Partial The browser UI and pipeline builder are vibe-codeable, but a robust PDF engine requires deep knowledge of the PDF specification, which the AI cannot reliably supply without existing libraries.
What it would actually take: A real version would be built on Rust crates such as lopdf or pdf-rs, compiled to WebAssembly with wasm-bindgen, with a web UI on top. The hard parts are correct handling of PDF object streams, cross-reference tables, font embedding, encryption, and compression across malformed real-world files. Building it credibly requires someone who knows the PDF format well, plus a large test corpus to catch edge cases.
