Overchat

OverChat.ai is a browser-based, no-registration platform that puts the four most powerful frontier models—GPT-4o, Claude-3.5-Sonnet, Gemini-1.5-Pro and Llama-3.1-405B—into one chat window. On landing, users pick any combination of models, type a single prompt and receive parallel answers in split panes, so strengths and weaknesses can be compared side-by-side without tab-switching. A prominent “Regenerate” button re-runs the same query on every selected model, while “Copy,” “Export Markdown” and shareable links let users move results into documents or social media in one click. Pricing is purely pay-as-you-go: after a small free credit, visitors top up with a card or crypto and are charged only for the tokens each model actually consumes, eliminating fixed monthly fees. The interface automatically tracks spend per model in real time and warns when credit is low. No conversation history is stored on OverChat servers; once the window is closed the thread disappears, giving GDPR-grade privacy by default. Power features include adjustable temperature, maximum token limit and system-prompt fields for every model, plus a JSON mode for developers who need structured output. Keyboard shortcuts, light/dark themes and responsive design make the same workflow usable on desktop, tablet or mobile without installing anything. In short, OverChat.ai is a minimalist, wallet-friendly way to multi-chat with the world’s best LLMs, compare their outputs instantly and keep full control over cost and data.
