Who We Are
PDF Workspace is built and run by Quantum4U Lab Pvt. Ltd., Gurugram, India. Articles are published by the PDF Workspace team at Quantum4U Lab.
02
How Our Articles Are Written
- Articles cover tasks people actually do with PDF files, using our own tools and tests.
- We use AI tools to help draft and edit articles. Every article is reviewed and fact-checked by a person before it is published.
- Plan limits and prices shown on the site are read from our live plan settings, so they match what the product enforces.

Corrections
If you spot an error, email hello@pdfworkspace.in. We correct factual errors and update the article's date when we do.

How AI Is Used in the Product
Some tools send your document's text to AI models to produce a result:
| Provider | Models | Used for |
|---|---|---|
| Anthropic | Claude Sonnet 4.5, Claude Haiku 4.5 | Summaries, chat with PDF, translation, comparison and other AI tools |
| OpenAI | GPT-4o-mini, text-embedding-3-small | Text tools and document search |
- Files you don't save are deleted automatically within 24 hours.
- We never use your documents to train AI models, and our AI providers do not train on documents sent through our API agreements with them.
- AI output can be wrong; see our Disclaimer.
