Humanpen

Humanize document files with HumanPen to lower their AI-detection score. Rewrite a whole .docx/.pptx, or only the passages a Turnitin/iThenticate AI report flagged, while keeping every fact, number, citation, table and formula intact. Also converts citations to one style (APA, MLA, IEEE, GB/T 7714), condenses a document to a word budget, and translates while preserving layout. Use when the user points at a document FILE (.docx/.pptx; translate also takes .pdf/.xlsx/.epub/.html/.txt) or such an AI report and wants any of these; not for text pasted into chat.

# HumanPen

A document-level AI humanizer. Point it at a document file and it uploads the file, waits for the job, and writes the result next to the source — you get a path back, **never the document's contents**. Formatting, tables, images, citations, and formulas survive intact.

**Every job spends the account's credits. State the cost and get the user's agreement before running any job command.** Per 1,000 words processed: humanize 100 credits, fix-citations 5, condense 20, translate 10, charged only on the words actually processed, with a 10-credit minimum per job; failed or cancelled jobs cost nothing.

## Setup

```bash
export HUMANPEN_API_KEY=hp_...   # create one at https://humanpen.net/settings/api-keys
```

New accounts get 100 free credits at https://humanpen.net. Without a key every command fails with instructions to get one.

## Commands

Run from this skill's directory; `python3` and nothing else is needed. `--help` on any command lists its flags. Add `-o PATH` to choose where the result lands (default `<name>-polished.docx` beside the source).

### Humanize — the main operation

Lower AI-detection signals on a `.docx` / `.pptx`. Three ways to scope it:

Slide Wright

arifszn/slide-wright

Create beautiful web presentations from a topic, rough notes, or an outline, and edit decks afterward — adding, removing, or revising slides. Generates a custom theme and a short two-slide preview, then builds the full deck only once the user confirms the direction; edits to an existing deck skip that flow and apply in place. Use when the user wants to make slides, a presentation, a talk deck, a pitch deck, or to add/remove/change a slide in one that already exists.
