CloseChat

Intro

CloseChat is a multi-end AI chat client that runs on desktop and mobile. It is designed to let users connect the client to AI services and models they select. The project documentation describes a focus on speed, visual polish, and privacy-oriented behavior: conversations and API keys are stored locally by default, with optional user-configured cloud synchronization. CloseChat is described in its materials as free to download and use; the service is provided under terms that users must accept before use.

Key Features

• Multi-end support for desktop and mobile, with multi-device cloud synchronization available when users configure a compatible cloud backend (documentation cites Alibaba Cloud OSS / S3-compatible storage).
• Default local storage of conversations and API keys, with an option to enable cloud sync to user-configured storage.
• Built-in capabilities called out in the documentation such as image generation, document reading, "artifacts", and multi-turn editing.
• Documentation and support resources including installation guides, migration tools, and a docs center that covers features and common questions.
• Core function: act as a client that connects to AI providers and models chosen and configured by the user.

Who this is for

CloseChat is suitable for users who need a consistent AI chat experience across desktop and mobile and who prefer to supply or configure their own AI provider or model. It is also appropriate for users who want local-first storage with an option to sync via their own cloud storage. Prospective users should be prepared to manage and secure their own API keys, configure cloud sync if desired, and accept the published terms of service that describe liability limitations.
