📖 How to use this interface
- 1Upload your DOCX file — drag it onto the zone below or click to browse. Works with Microsoft Word, LibreOffice, or Google Docs exported as .docx. Images are preserved automatically.
- 2Fill in the book details — title, author, language. These become the EPUB metadata visible in every e-reader.
- 3Optional: add a cover image (JPG or PNG). It will appear as the EPUB cover in Kindle, Apple Books, Kobo, and all standard readers.
- 4Click Convert to EPUB. Processing runs entirely in your browser — nothing is uploaded to any server.
- 5Download your EPUB file. The filename will be based on your book title — recognisable and ready to publish.
DEMI Enrichment (optional): Toggle on to add a Conceptual Core, UPL reference code, and Registry Record to your EPUB metadata. Requires your Anthropic API key — costs approximately $0.005 AUD per analysis. The conversion itself is always free.
Reset: Use the ↺ Reset button to clear all fields and start a new conversion at any time.

Direction D — EPUB → DOCX
Upload any EPUB file. Extract and clean the text. Download a ready DOCX — suitable for editing, re-publishing, or uploading to another platform (OpenAI, author.today, Squarespace). Optional Claude API cleanup removes platform artefacts and normalises structure without touching your voice.
💡 When to use this
Moving content from one publishing platform to another — Squarespace → author.today → GPT Store → Word. Or cleaning up an EPUB that came from a web copy-paste (zero-width spaces, broken links, formatting noise). Toggle Claude Cleanup for intelligent structural cleanup powered by the API.
