The best Docs, Content & SEO plugins for ChatGPT & Codex

33 plugins in our Docs, Content & SEO shelf (PDFs, transcripts, notes and words.), ordered by what we can actually measure: our editor's picks first, then GitHub stars (checked 2026-10-26). Archived repos go to the bottom.

Stars measure popularity, not quality or safety. We haven't installed or audited these; every description is the project's own. Read the code before you install anything. Paid placements never affect this order.

Most-starred right now: BabelDOC PDF Translate by reliable-ly0411.
