Deni AI

AI Chatbot for Everyone — access modern AI models in one place

Deni AI is a multi-model AI chat app for people who want strong model choice without juggling many separate subscriptions. It supports OpenAI, Anthropic, Google, Groq, xAI, and more via platform keys or bring-your-own-key (BYOK).

Live app: https://deniai.app

Features

• Multi-model chat — switch between OpenAI, Claude, Gemini, Groq, xAI, and other routed models
• BYOK — connect your own provider API keys (encrypted at rest); BYOK usage is not counted against platform limits
• Tools — web search (Brave), page browse, image generation, and video (Veo) where enabled
• Memory & projects — personalization memories and project-scoped context for organized chats
• Teams — organizations, seats, and shared Pro access with usage visibility
• Billing — Stripe subscriptions (personal and team); optional self-host disable via NEXT_PUBLIC_BILLING_DISABLED
• Affiliate referrals — shareable invite links, QR codes, milestone reset credits, and selectable paid-plan rewards (three resets or a manually sent 30% OFF coupon)
• Auth — Google / GitHub OAuth, magic link, anonymous guest, passkeys, and 2FA (better-auth)
• i18n — English and Japanese (next-intl)
• Public guides & blog — original articles on model choice, verification, and practical AI use, available without an account
• PWA — installable progressive web app assets and service worker
