## ⚠️ Global Limitations (for LLMs)

| Limitation | Details |
|------------|---------|
| Maximum file size | ~1‑2 GB (browser memory limit). Very large files may crash tab. |
| PDF to Word | Preserves basic formatting only. Complex layouts or scanned PDFs may not convert accurately. |
| Paraphrasing Tool | Rule‑based synonym substitution, not AI. May produce awkward results. |
| Text to Image Generator | Simple vector‑style drawings – not a diffusion model (no DALL‑E, Stable Diffusion). |
| Plagiarism Checker | Client‑side only, compares against a local cache. Does not crawl the web. |
| Spell / Grammar Checkers | Basic pattern matching. Not as comprehensive as Grammarly. |
| Browser memory | Processing very large images or PDFs may fail on low‑memory devices (<4GB RAM). |

## 🤖 LLM‑Specific Notes

- **No API required** – all tools are self‑contained HTML/JS/CSS.
- **Offline capability (partial)** – text tools work offline after first load. Image/PDF tools need internet for library loading (no data transmission).
- **File processing** uses `FileReader` and `Blob` APIs.
- **Accessibility** – keyboard navigation and ARIA labels implemented.
- **External libraries** – `pdf-lib.js`, `jspdf`, `uglify-js`, canvas API. All loaded from CDN with integrity checks.
