Wiz.chat
Wiz.chat is a browser-based character chat web app that runs AI conversations on your own computer instead of a remote server. Open the site in Chrome, pick or create a character, and chat without creating an account or installing software. The homepage pitches it as free, private, and local AI for people who want character roleplay without handing chat logs to a cloud service.
Most character chat sites route every message through their servers and charge subscriptions or mine conversation data. Wiz.chat flips that model by using your local GPU through browser hardware acceleration, so prompts and replies stay on your machine. That trade-off means performance depends on your graphics card and you need the latest Chrome, but you get unlimited use at no cost and no vendor copy of your chats.
It fits role-players, fiction writers, and privacy-minded users who want imaginative character dialogue in a web tab. The product is in alpha, so expect a smaller polish layer than mature cloud rivals, but the local privacy angle is the main draw.
