Documentation
Guides, privacy notes, and practical workflows for ASD123.ai's browser-based text, context, and chat tools.
Optimizer
Clean and standardize AI-generated text before publishing, pasting into business tools, or adapting content for regional conventions.
Language Mapping
Region-specific mappings for Swiss German, German, French, Italian, and English variants.
Text Cleanup
Remove citations, Markdown, diacritics, special spaces, and stylized Unicode text.
Local Preferences
Settings can be remembered locally in your browser. Text content is not stored by ASD123.ai.
Anonymizer
Explore local PII detection, reversible placeholder mappings, and LLM deanonymization workflows. Treat this tool as an experimental proof of concept and review aid.
Regex Default
Fast local pattern matching for emails, phone numbers, IBANs, IDs, URLs, and other structured PII.
OpenAI Privacy Filter
Optional local AI detection via Hugging Face Transformers.js. First load is about 950 MB and requires WebGPU.
Legacy PoC AI4Privacy
Available for comparison, but no longer the recommended AI path.
Local AI Chat
Chat with WebGPU models directly in your browser. Prompts, uploads, generated text, and chat history stay on your device.
Local WebGPU Models
Load Gemma and Qwen ONNX models in the browser. Model files are downloaded, but prompts are not sent for remote inference.
Files and Images
Attach images, text, Markdown, PDF, or DOCX files. Extraction happens locally before content is added to the prompt context.
History and Export
Chats are stored in browser IndexedDB, can be deleted locally, and can be exported as Markdown.
Context Estimator
Estimate how much AI chat context you need for pasted text or local documents before choosing 4K, 8K, 16K, or larger model settings.
Context Recommendation
Compare 4K through 128K windows and see which one leaves enough room for an answer.
Local File Extraction
TXT, DOCX, and PDF files are read in the browser. File contents are not uploaded for processing.
Model Profiles
Generic, Llama / Mistral, Qwen, Gemma, and GPT-style profiles keep the estimate fast without tokenizer downloads.
Markdown Converter
Turn PDF and DOCX documents into clean Markdown locally. Useful before feeding text into AI chats, the Optimizer, or the Anonymizer.
PDF and DOCX
pdf.js extracts PDF text with font-size based heading detection. mammoth.js maps Word styles to Markdown.
Selectable parsing engines
Optional EdgeParse and LiteParse WebAssembly engines for better multi-column and table layout, plus PP-OCRv6 OCR for scanned PDFs and images (PNG, JPG, WebP). Each loads locally on demand.
Preview and Export
Switch between raw Markdown and rendered preview, then copy to clipboard or download a .md file.
Privacy and Limits
The tools are designed for local browser processing. Optional AI modes download model files into your browser, but your text, prompts, attachments, chat history, context estimates, and anonymization mappings remain local. PII detection and context estimation can miss edge cases, so manual review is still required.
