Anthropic's document skills, the implementation behind Claude's file features: create, edit and analyze Word, Excel, PowerPoint and PDF files, including tracked changes, comments, formulas and form filling. Source-available, not under an open-source license.

Extracts text and tables from PDFs; merges, splits and rotates pages, adds watermarks, fills forms and OCRs scanned documents. The official Anthropic skill behind Claude's document features; source-available, not open source.

OCRs photos of visa documents such as bank, employment or income certificates, translates them into English and builds a side-by-side bilingual PDF. Needs Python (pillow, reportlab) and an OCR engine. Not an official certified translation: verify names, amounts and dates.

Reads messy invoices and receipts (PDFs, scans, screenshots), extracts vendor, date and amount, renames and files them by vendor, category or year, keeps originals and can export a CSV for your accountant. Needs an agent with local file access; no account required.

Translates full PDF papers while preserving formulas, charts and layout (command pdf2zh), outputting monolingual and side-by-side bilingual PDFs. Uses Google Translate by default and can switch to DeepL, OpenAI and others; also runs as an MCP server.

Adds a searchable, copyable text layer to scanned PDFs, with automatic deskew, rotation and size optimization, outputting PDF/A by default. Built on Tesseract, supports 100+ languages and runs fully locally.

Anthropic's official small-business skill for bills: reads vendor, amount and due date from email, PDFs or photos, dedupes, codes to accounts, matches POs and drafts a payment plan. Posting and paying each need approval; it never auto-pays. Works with QuickBooks, Xero, NetSuite or file export.

MiniMax's official skill plugin with dev guides for frontend, full-stack, Android, iOS, Flutter, React Native and GLSL shaders, plus PDF, PowerPoint, Excel and Word document skills and image, video and music generation. Media skills need a MiniMax API key. Still in beta.

Optimizes websites for AI search: checks whether ChatGPT, Perplexity and Google AI Overviews can cite your site, covering AI crawler access, llms.txt, structured data, E-E-A-T and technical SEO, and writes client reports. PDF reports and scoring need the README install script, Python 3.8+ and Git.

Reads the exact position of every character, line and table cell in digital PDFs: the CLI exports layout-preserving text or CSV/JSON details, and the Python API extracts tables and form fields, ideal for invoices, statements and reports. Runs locally with Python; scans need OCR first.

PDF translation CLI for research papers that preserves formulas and layout as much as possible, producing bilingual side-by-side or translation-only PDFs. Needs an OpenAI-compatible API (local Ollama works too); currently focused on English to Chinese.

PDF command line written in pure Go with almost no external dependencies: dozens of subcommands to merge, split, crop, rotate, watermark, encrypt and decrypt, extract images and fonts, and work with forms.

Mixedbread's official semantic grep: search code, text, PDFs and images in natural language, and hook it into Claude Code, Codex and other coding agents in one step to cut token use. Requires a Mixedbread sign-in, and files are synced to its cloud index.

Open-source PDF table extraction with a camelot CLI: exports tables from financial reports, bank statements and statistical reports to Excel, CSV or Markdown, with an accuracy score. Needs Python 3.10+; handles text-based PDFs by default, scans need the ml and ocr extras. Double-check results.

PDFMathTranslate 2.x (command pdf2zh_next), built on BabelDOC: translates papers and other PDFs while keeping formulas, charts, TOC and annotations, outputting translated and bilingual side-by-side versions. Uses a free translation channel by default, or your own OpenAI, DeepSeek or other API key.

Extracts issuer, amount, date, invoice number and other fields from PDF invoices using YAML/JSON templates, exporting CSV, JSON or XML. Ships several text-extraction backends, OCR for scanned invoices and an optional AI fallback.

Translates entire books: splits PDF, DOCX or EPUB into chunks for parallel subagents, keeps terminology consistent, resumes interrupted runs and verifies with hashes, then outputs HTML, DOCX, EPUB or PDF. Needs Calibre, Pandoc and Python.

Local LLM-powered document translator for PDF, Word, Excel, EPUB, SRT subtitles and more; Word and Excel keep their formatting, glossaries can be built automatically, and agents can submit jobs via MCP. Needs uv and an OpenAI-compatible API key; translated PDFs lose the original layout.

Helps Indian resident individuals prepare income tax returns: the agent reads Form 16, AIS and more, asks about deductions, computes tax with a tested Python program, compares old and new regimes and builds a filing checklist; you pay and file yourself. AY 2026-27 only; Python 3.

130+ office skills for contract review, NDAs, job descriptions, offer letters, invoices and expenses, meeting notes, email, and Excel, PowerPoint and PDF work. Writing skills work as-is; Airtable, Slack and other automations need those services. Legal and finance output needs expert review.

Open-source European e-invoicing tool whose CLI validates, extracts and creates ZUGFeRD, Factur-X and XRechnung invoices (PDF or XML) and renders XML invoices as readable HTML or PDF, for EU invoicing compliance. Needs Java; download the Mustang-CLI jar from the project site.

Python library with a CLI for Factur-X (ZUGFeRD 2.x), the French-German e-invoicing standard: combine a regular PDF invoice and XML into a Factur-X invoice, extract the XML from invoice PDFs and validate it against the official XSD; also handles Order-X and UBL. Needs Python 3.

Official MCP from Nutrient (formerly PSPDFKit): merge PDFs, convert between Office and PDF, OCR, watermark, redact personal data, add digital signatures, and extract fields from invoices and contracts. Files are processed in Nutrient's cloud; needs a free account (page-based credits) and Node.js.

DeepL's official CLI: translate text and PDF, Word, PowerPoint and Excel documents while keeping formatting, with glossaries and translation memory. Needs a DeepL API key (free plan available); install from source with Node.js 24.15+. Have legal translations reviewed.
