Chatworm

Chatworm is an open source web chat client that connects directly to the APIs of major AI model providers. Instead of paying for a single chat subscription, a user pastes their own API keys and chats with models from OpenAI, Anthropic, Google Gemini, DeepSeek, Alibaba Qwen, xAI Grok, Mistral AI and StepFun, switching between them when one is slow or unavailable. The interface exposes the settings that a bare API offers: the active model, randomness, maximum tokens and reasoning effort. It also supports spoken conversation, with speech to text input and text to speech replies using a choice of voices, an option to send as soon as speech ends, image generation with DALL E 3, and photo analysis through vision capable models. Chat history and a dark mode are customizable. Chatworm is available as a web app, an Android app and a Windows app, and the source code is published on GitHub with a license page and third party license notices. A short setup flow asks the user to obtain an API key from a chosen provider and continue. The site says images on the page were generated with Midjourney and notes that users are interacting with an AI system. The app does not publish a price of its own. Costs are the usage charges of whichever providers the user connects through their own keys.
