Chapper is a powerful, privacy-first LLM and AI chat client for iPhone and iPad that connects directly to your local or self-managed AI server. No accounts, no forced cloud, no subscription. Whether you run LM Studio, Ollama, llama.cpp, or another OpenAI-compatible endpoint, Chapper gives you a polished, fully native iOS experience for chatting with your models, managing conversations, tuning inference settings, working with memory, exporting chats, and integrating practical tools. Built in SwiftUI from the ground up, Chapper is designed to feel like a proper iPhone and iPad app, not a web wrapper. FEATURES — Personas Create and switch between custom AI personas, each with their own system prompt, tone, and language. Built-in personas include Code Expert, Translator, Teacher, Analyst, Brainstormer, and more. — Thought Process See how reasoning models think. Chapper surfaces the reasoning output of supported models like DeepSeek-R1, Qwen3, and other reasoning-capable models in a collapsible panel above each response. — Rich Markdown Rendering Responses are rendered with full Markdown support, including tables, code blocks, bold text, lists, and more. — Model Management Browse, inspect, select, load, and unload models directly from the app where supported. View quantisation, context length, tool-use capability, vision support, and active status at a glance. — MCP Tools Built-in tool integrations for practical workflows: web search, current time, server status, model listing, chat search, file and directory access, URL fetching, and export actions. — Files App Integration Access and manage Chapper’s workspace directly in the iOS Files app, including MCP-related folders and exported content where supported. — Memory Save useful long-term information and inject it into conversations automatically, so your assistant stays consistent across chats. Includes custom memory types and memory graph support. — Scratchpad A built-in scratchpad for temporary notes, drafts, prompts, or working context while chatting. — Prompt Templates Save and reuse your most-used prompts with a single tap. — Full Parameter Control Adjust temperature, token limits, repeat penalty, Top-K, Top-P, Min-P, TFS-Z, Flash Attention, KV-cache offload, context length, keep-alive, structured output, and more. — Search Full-text search across all your conversations and message content. — Export Export any conversation in 7 formats: TXT, PDF, HTML, Markdown, JSON, CSV, and XML. — Keychain Support API keys can be stored securely using the iOS Keychain. — iCloud Sync Optionally sync your chats across devices using iCloud. — Analytics Dashboard View on-device usage stats and activity insights inside the app. — Text to Speech Listen to responses with built-in playback controls and support for native, local, or server-based TTS configurations. — Chat Info Inspect detailed metadata for conversations, including timestamps, counts, tags, folder assignment, and more. — Server Tools Quickly configure, reuse, and manage your server connections for a smoother local AI workflow. — Chapper Pro One-time purchase. Unlock unlimited chat history, all export formats, advanced sampling controls, themes, and all future Pro features. No subscription. REQUIREMENTS Chapper is designed for locally hosted or self-managed AI backends, including LM Studio, Ollama, llama.cpp, and OpenAI-compatible servers. Some features depend on the capabilities of the connected model or server. PRIVACY Chapper is built with privacy in mind. Your chats stay on your device unless you explicitly enable iCloud sync or connect to your own external server. No accounts required. No third-party tracking. Chapper is built for people who care about local AI and LLMs, model control, privacy, and a real native iOS experience.
