🧰 Browser tools — asd123.ai
Six free AI text tools that run 100% in your browser. Nothing you type or upload ever leaves your device — verifiable in your browser's network tab.
| Tool | What it does |
|---|---|
| Optimizer | Clean AI-generated text: em dashes, smart quotes, Markdown, citations, fancy Unicode |
| Anonymizer | Detect and anonymize PII with reversible placeholders before sharing text with AI |
| Local AI Chat | Chat with open models (Gemma, Qwen) via WebGPU — no install, no account |
| Context Estimator | Count LLM tokens offline and pick the right context window |
| Markdown Converter | PDF, DOCX, PPTX, Excel, HTML → clean Markdown, with local OCR for scans |
| Text to Speech | Natural voices in five languages, generated on your device |
Native, open-source applications — same privacy-first mindset, beyond the browser. All GPLv3.
| App | What it is |
|---|---|
| rdp123 | A minimal, fast RDP client for macOS. Native AppKit in Rust — ~8 MB installed, lives in the menu bar, passwords in the Keychain |
| rustquit | Auto-quits macOS apps when their last window closes. A tiny, defensive menu bar utility in Rust |
| photo-shot | Mobile-first, self-hosted PWA for AI image editing across Gemini, WaveSpeed and OpenRouter, plus an EXIF metadata copier |
- Local first — your data does its job on your own devices
- No telemetry, no accounts, no tracking — not as a promise, but by architecture
- Free software — GPLv3, source in front of you, build it yourself
- Small on purpose — native code, no Electron, no bloat
