Cumbersome: AI LLM API Client

关于这款应用

Cumbersome is an AI LLM API client designed for users who require direct control over their interactions with large language models. Developed by Folding Sky Co, it serves as a versatile tool for accessing major providers such as OpenAI, Anthropic, Google AI Studio, and OpenRouter, as well as custom OpenAI-compatible endpoints like Ollama and LM Studio. The application emphasizes privacy by design, syncing conversations via iCloud without storing data on developer servers.

Key capabilities include the ability to tune API parameters, switch providers mid-conversation, and compare models head-to-head in parallel streams. Users can manage rich conversations with Markdown, LaTeX, code blocks, and attachments. Advanced features support local browser use, web search, image generation, and running JavaScript or HTML directly within chats. The app offers extensive customization through chat themes, reading fonts, folder organization, and system message presets. Core functionality is free, with an optional Pro subscription for advanced project tools; users pay providers directly for API usage.
