SynTask

Read full description

SynTask is a multi-model AI chat client that lets you connect your own provider accounts, choose the right model for each task and compare answers in one private workspace. CONNECT YOUR AI PROVIDERS Add your own API keys for supported services, including OpenAI, Anthropic, OpenRouter, DeepSeek, Mistral, Groq, Together AI and Perplexity, or connect a compatible custom endpoint. Switch providers and models without rebuilding your workflow. COMPARE MODELS IN ARENA Send one request to several models, review their answers side by side and let a selected model synthesize a final response. Availability depends on your connected providers, keys and model access. BUILD REUSABLE WORKFLOWS • Create prompt skills for recurring tasks. • Connect trusted remote MCP servers and use their tools in supported chats. • Work with text, images, files and voice when the selected model supports them. • Use local conversation memory to retrieve relevant context. • Run supported actions through Shortcuts and Siri. PRIVACY BY DESIGN API keys and MCP authorization headers are stored in the device Keychain. Chats, attachments and the memory index are stored locally until you delete them. SynTask has no intermediary AI server: when you send a request, the selected content is transmitted directly from your device to the AI provider you chose. If you enable an MCP tool, the required arguments may also be sent to the tool server you configured. IMPORTANT INFORMATION SynTask does not provide, sell or resell AI models, API keys, tokens or provider accounts. A separate account and API key from a supported third-party provider are required. Providers may charge for API usage and apply their own availability, age, regional, content, retention and rate-limit rules. SynTask does not control those services. AI-generated responses may be inaccurate, incomplete or inappropriate. Verify important information independently. SynTask is not a substitute for professional medical, legal, financial or other expert advice. Do not send information you are not authorized to share. SynTask is an independent client and is not affiliated with, endorsed by or sponsored by the third-party AI providers it supports. Provider and model names are trademarks of their respective owners. Features vary by provider and model.
