What is Anse?

Anse is an open-source web front end for conversational AI, published as the anse-app project with a hosted demo at anse.app. It does not ship its own model: it provides the interface layer, with a provider plugin system that connects OpenAI-compatible endpoints and image services, conversation modes for single exchanges, continuous chat and image generation, and model parameters such as temperature exposed in the settings panel. Chat history stays in the browser via IndexedDB, and deployment templates cover Vercel, Netlify, Docker and Node. For anyone wanting a private chat UI over their own API keys, that combination is the point.

FAQ

Does Anse include a language model?

No. It is a client. You connect an API key from a provider such as OpenAI or point it at a self-hosted endpoint, and the application handles the conversation interface, local history and settings around it.

Why bother self-hosting a chat interface?

Control. Prompts and history stay on infrastructure you manage, and you can aim the app at whichever provider or local model your policy permits instead of depending on one vendor's web app.

Is it the same kind of tool as Andi or You.com?

Not really. Those run search indexes of their own, while Anse is an open-source interface you run yourself. It appears in the same category only because it answers questions in natural language.
