Show HN: CiteLLM – Verify AI Answers in PDFs

CiteLLM is a tool that links every AI answer, claim or extracted value to the exact passage in the original PDF, with the passage highlighted, and lets reviewers approve or flag each result and export an evidence report. It is offered as a plugin for ChatGPT and Claude, a standalone web app, document search with passage-level citations, and structured extraction with an API. The site states that documents are never used to train models, files are deleted after processing by default, and a Docker self-host option is available.
