Problem

Existing AI chat platforms store conversations on remote servers, raising privacy concerns. Their UIs are often sluggish and lack customization options.

Solution

Created a fully client-side chat interface supporting multiple LLM providers. All data stays in the browser via IndexedDB and LocalStorage, with full parameter control and fast, responsive UI.

Overview

JustBYOK supports multiple LLM providers including OpenAI, Anthropic, and Google with full parameter control, conversation organization, and a clean, intuitive interface. No server-side data storage. Everything stays in your browser.
