Next.js AI Chatbot
Vercel’s open-source Next.js template for building and deploying a customizable AI chatbot.
Next.js AI Chatbot, now called Chatbot by Vercel, is an open-source starter project for building your own AI chat application. It combines a customizable web interface with model-provider integration, authentication, saved conversations and file storage. Developers can deploy it on Vercel or configure a local development environment. The template is free, but operating an application can incur model, hosting, database and storage charges. It suits teams that want control over their chat experience and can maintain the deployment; it is not a ready-made service with unlimited free model access.
