Every week there is a new AI-powered service promising to change your workflow. Most of them share two problems: they cost money, and they send your data to a server somewhere.
What if you could get real AI-powered tools — text-to-speech, image upscaling, background removal, and more — all for free, all running locally in your browser, with zero data leaving your machine?
That is exactly what I built over at AIXHDD. Here is every tool, what it does, and why you might need it.
Audio Tools
Text-to-Speech
The tool: AIXHDD Text-to-Speech
Convert any text into natural-sounding speech, right in your browser. Choose from multiple voices, adjust speed and pitch, and download the result as MP3. Most TTS services charge per character or require API keys. This one is completely free — unlimited text, no signup, no credits.
Image Tools
Background Remover
The tool: AIXHDD Background Remover
