From U-Net segmentation to modern transformer-based matting, we walk through how a single neural net can isolate a foreground subject in a photo, and why edges and hair are still the hard parts.

Old image upscaling guesses pixels with smooth math. AI upscalers like ESRGAN and Real-ESRGAN hallucinate plausible detail learned from millions of images. Here's the difference and where each fails.

OCR turns pixels back into text — a problem that took decades to crack. We trace the journey from template matching through Tesseract LSTMs to modern multimodal models.

Whisper handles 99 languages, accents, background noise, and code-switching better than anything before it. We unpack the encoder-decoder transformer architecture that made it possible.

A free browser vocal remover does center-channel cancellation in ten lines of JavaScript. An AI tool runs a neural network trained on tens of thousands of stems. Here's why the AI sounds dramatically better, when the simple math is enough, and the honest tradeoffs between privacy, speed, and quality.
