An AI agent can help analyze a report, but it first needs to read the document. Firecrawl's AnyDoc<\/strong>, turns office files, EPUB books, and PDFs with text into Markdown<\/strong>. The common conversion happens on your machine; hosted OCR is a separate option, which requires privacy considerations.<\/p>\n In this guide we will install the tool for the Linux user only, convert documents from the terminal, and create a shared skill between Claude Code and Codex. If you're just getting started, also check out the AI assistants on the Linux terminal<\/a>.<\/p>\n The project is centered in Rust with an MIT license and has interfaces for Node.js, Python, and WebAssembly. It receives documents and produces GitHub-Flavored Markdown, the format with tables and other features used on GitHub. The official list includes:<\/p>\n Detection uses content signatures when available. CSV is an important exception: when reading from standard input, explicitly specify the format. The flow below separates the local conversion from the optional OCR path:<\/p>\n Markdown is useful for consulting content, not for reproducing every visual detail of a page. After the conversion, check the titles, tables, and representative excerpts before using the output as the basis of an analysis.<\/p>\n The npm package requires Node.js 20 or later<\/strong>. Check the existing environment before installing:<\/p>\n In the tests for this article we used AnyDoc 0.2.4<\/strong>. The command below pins that version and installs into The installation above worked with lifecycle scripts disabled. The package uses the native component distributed for the platform. If your operating system and architecture combination does not have a compatible package, check the installation error rather than simply enabling scripts or using sudo.<\/p>\n If To read an existing document and print the Markdown to the terminal:<\/p>\n To save the output, choose a new file. Before running the example, replace the paths with the documents you actually want to convert:<\/p>\n Check the destination before using You can test standard input with a CSV created on the fly:<\/p>\n The output will be a Markdown table. Each CLI run works with a single document. For large files, prefer saving to disk and examining only the needed sections, rather than dumping the entire text into the agent's context.<\/p>\n A PDF with a text layer can be converted locally. A page made up only of an image requires optical character recognition, a capability that AnyDoc does not perform on its own. In that case, the default conversion fails, instead of pretending it extracted the entire document.<\/p>\n There is an integration option with Firecrawl Parse:<\/p>\n The entire file is uploaded<\/strong>, including pages that already contain text. Do not use this option automatically on contracts, customer data, or internal documents. For a strictly offline workflow, stop when the need for OCR arises and use a previously approved local tool.<\/p>\n The project documents hosted access without sign-up and a key for higher limits. This is not a guarantee of availability, unrestricted free use, or permanent limits. When a key is configured, prefer the variable The repository already provides an official skill, installable with The Codex reads personal skills in If the skill or the link already exists, review the installation instead of running the block again and overwriting your version. The example maintains a single copy of the instructions. Open a new session of the agents to check the discovery; you can ask The skill guides the agent; it does not replace tool permissions nor turn the content of a document into reliable instructions. This organization complements the workflow presented in AI skills in the CLI<\/a>.<\/p>\n Within a project, prefer the library instead of starting a terminal process for each document:<\/p>\n Save the example as The API also accepts bytes with While preparing this guide, the user installation was tested with synthetic documents in CSV, RTF, DOCX, ODT, EPUB, XLSX, and PDF with text. We also checked a DOCX with a changed extension, reading CSV from standard input, and writing to a file. This validates those scenarios, it does not certify the entire list of formats nor any real document.<\/p>\n A PDF made up only of an image was rejected without upload. Nonexistent file, invalid document, unknown option, and invalid format also produced recognizable failures. In the Node.js API, we tested DOCX by path and CSV by bytes.<\/p>\nWhat AnyDoc does<\/h2>\n
