How browser-based AI actually works, and how to get real work done with it — privately, for free, without uploading a single file. Looking for a finished job instead of an explanation? Start with the end-to-end workflows.
Score how machine-like your draft reads, then rewrite it word by word — all on your own device. How a rules engine, Chrome’s built-in AI, and a local 1.5B-parameter language model work together, and why no AI detector should be trusted as a verdict.
Find passages in a 200-page contract or a stack of research papers by meaning, not by keyword. How pdf.js text extraction, all-MiniLM-L6-v2 embeddings, and cosine similarity search work together entirely on your device.
Remove vocals for karaoke, extract an a cappella track, or clean up a noisy recording — all without uploading audio. How stereo phase separation isolates centered vocals, and how RNNoise cleans steady background noise in real time.
Shrink MP4, MOV, and MKV files entirely in your browser. How WebCodecs, a WASM demuxer, and a JavaScript muxer replace server-side ffmpeg — and which codec to pick when H.264, VP9, and AV1 give very different file sizes.
Scratch removal, face enhancement, and upscaling combined in one on-device pipeline. How LaMa inpainting, GFPGAN face restoration, and Swin2SR super-resolution work together — and where each one helps or falls short.
Enlarge a photo by 2× or 4× while reconstructing detail instead of blurring it. How Swin2SR works in WebAssembly and WebGPU, why oversized inputs are capped, and the honest limits of hallucinated detail.
A practical guide to shrinking JPEG, PNG, WebP, and AVIF files in your browser with the same codecs cloud services use — plus settings that balance file size and quality, with zero uploads.
A complete walkthrough of transcribing meetings, interviews, and voice memos in your browser with Whisper-based speech-to-text — no uploads, no per-minute fees, with tips for accuracy and export.
A plain-English tour of the two browser technologies that make local AI possible: WebAssembly for portable compute, WebGPU for GPU acceleration — what each does, when they fall back, and what to expect on your device.
Cloud AI means uploading your files to someone else's server. Browser-based AI flips that model: the model downloads once, then everything runs on your device. Here is why that matters for privacy, cost, and speed.
