Smooth PDF Reader

By Sen Wu

Overview

Read PDFs smoothly inside Codex, with responsive page rendering and the familiar "Ask for change" workflow. Open a local PDF or a host-provided file with continuous scrolling, cached page images, independent text selection, search, page entry, zoom and bookmarks. Select text or a figure to compose a contextual comment in supported Codex and ChatGPT hosts; you decide when to send a chat draft. Local-file PDF contents are processed on your device, not uploaded to this service. The hosted service delivers the interface and libraries. Host-provided resources and comments follow the host's privacy settings. This reader does not edit or sign PDFs, perform OCR, or open password-protected documents. Files are limited to 512 MiB and performance depends on your device and document. Operating-system file actions are available only in the separate local edition.
