Use it when your goal in research and sources is clear and you can limit it to the data and actions it actually needs.

Extract text from PDFs/scans (pymupdf, marker-pdf)
What does it add to Hermes?
Extract text from PDFs/scans (pymupdf, marker-pdf)
Ocr And Documents is a skill related to research and sources. It gives the agent a way to find external information and sources instead of relying only on model memory.
This plain-language explanation is based on the publisher description. The original text remains visible for verification.
Do not add it merely to experiment when Hermes already has a simpler path, or when you cannot review its source and permissions.
Best for users who want a repeatable way of working inside Hermes.
Ask for one recent fact with two sources, then open both links and verify dates and evidence.
Extract text from PDFs/scans (pymupdf, marker-pdf)
This entry was indexed from Hermes Bundled Skills. Our explanation interprets the type and domain without inventing a capability not present upstream.
The source is official or editorially reviewed, but you still need to review permissions and version compatibility.
Inspect, install, then test.
- 01Open the source
Match the publisher, license, and description to your need. Check the real update history.
- 02Review permissions and secrets
Never paste a secret value into this site. Use environment-variable names and grant the smallest scope.
- 03Copy setup only after review
The controls below copy text. They do not execute commands on your device.
- 04Test with a non-sensitive task
Inspect the visible tools, then exclude write or delete tools you do not need.

This skill covers text extraction from PDFs and scanned documents.
Coming from aread_fileEXTRACTION COVERAGE WARNING?read_fileauto-converts local PDFs but reads the text layer only; the warning footer lists the pages that yielded no text (scanned images). For a handful of pages, render + vision is fastest:pdftoppm -jpeg -r 150 -f N -l N file.pdf /tmp/pagethenvision_analyzeeach image. For bulk OCR of many pages, use marker-pdf below (Step 2).
Step 1: Remote URL Available?
Ordered, practical steps. Run one and confirm it worked before moving on.
If the document has a URL, always try web_extract first:
web_extract(urls=["https://arxiv.org/pdf/2402.03300"])
web_extract(urls=["https://example.com/report.pdf"])This handles PDF-to-markdown conversion via Firecrawl with no local dependencies.
Only use local extraction when: the file is local, web_extract fails, or you need batch processing.
Step 2: Choose Local Extractor
Ordered, practical steps. Run one and confirm it worked before moving on.

| Install size | ~25MB | ~3-5GB (PyTorch + models) |
| Speed | Instant | ~1-14s/page (CPU), ~0.2s/page (GPU) |
Decision: Use pymupdf unless you need OCR, equations, forms, or complex layout analysis.
If the user needs marker capabilities but the system lacks ~5GB free disk:
"This document needs OCR/advanced extraction (marker-pdf), which requires ~5GB for PyTorch and models. Your system has [X]GB free. Options: free up space, provide a URL so I can use web_extract, or I can try pymupdf which works for text-based PDFs but not scanned documents or equations."

Explains the idea itself. Read it slowly; the later sections build on it.
pymupdf handles these natively — use execute_code or inline Python:
# Split: extract pages 1-5 to a new PDF
doc = pymupdf.open("report.pdf")
new = pymupdf.open()
for i in range(5):
new.insert_pdf(doc, from_page=i, to_page=i)
new.save("pages_1-5.pdf")# Merge multiple PDFs
result = pymupdf.open()
for path in ["a.pdf", "b.pdf", "c.pdf"]:
result.insert_pdf(pymupdf.open(path))
result.save("merged.pdf")# Search for text across all pages
doc = pymupdf.open("report.pdf")
for i, page in enumerate(doc):
results = page.search_for("revenue")
if results:
print(f"Page {i+1}: {len(results)} match(es)")
print(page.get_text("text"))No extra dependencies needed — pymupdf covers split, merge, search, and text extraction in one package.

Notes
Explains the idea itself. Read it slowly; the later sections build on it.
web_extractis always first choice for URLs- pymupdf is the safe default — instant, no models, works everywhere
- marker-pdf is for OCR, scanned docs, equations, complex layouts — install only when needed
- Both helper scripts accept
--helpfor full usage - marker-pdf downloads ~2.5GB of models to
~/.cache/huggingface/on first use - For Word docs:
pip install python-docx(better than OCR — parses actual structure) - For PowerPoint: see the
powerpointskill (uses python-pptx)
