ATTACH IMAGES & FILES Pick a photo from your library or attach a text or PDF file directly to your message. Vision-capable models can analyze images; text files are embedded as context so the AI understands your documents. SMART SYSTEM PROMPTS Choose from built-in prompt templates -- General Assistant, Blog Writer, Code Expert, Translator, Academic Editor, Creative Writer -- or craft and save your own. Each conversation can have its own persona. PER-CONVERSATION PARAMETERS Fine-tune Temperature, Max Tokens, Top-P, and streaming mode for every chat independently. Add custom key-value parameters for advanced API features without touching a single line of code. MCP TOOL INTEGRATION Connect external tools and data sources via the Model Context Protocol (MCP).

Dark mode and Dynamic Type are fully supported. YOUR DATA, YOUR CONTROL Thinklet stores everything -- conversations, settings, API keys -- locally on your device using iOS secure storage. No account, no cloud sync, no telemetry.
