## What is YamabikoChat?

YamabikoChat is a privacy-focused, Bring-Your-Own-Key (BYOK) multi-LLM chat client for iOS.

No in-app subscriptions or marked-up token fees are required. Simply register your own API keys for providers like OpenAI, Google Gemini, and OpenRouter, and chat directly with the latest AI models at cost price.

◆ KEY FEATURES
1. Multi-Provider Support
Easily connect to OpenAI, Google Gemini, OpenRouter, or your own custom OpenAI-compatible API endpoints.

2. Privacy-First & Local-First Design
Your API keys and access tokens are securely stored in the iOS Keychain. Chat history, attachments, and diagnostic logs stay strictly on your local device. The app never sends your data to third-party middleware.

3. Vision Model & Media Support
Quickly attach photos and images from your photo library to chat with multimodal models like GPT-4o or Gemini 1.5 Pro.

4. Voice Dictation
Dictate messages hands-free using iOS native speech recognition and microphone access.

5. Seamless Share Extension
Share text or URLs directly from Safari or other apps into YamabikoChat to initiate a draft conversation instantly.

◆ REQUIREMENTS
YamabikoChat is a client application. You will need to bring your own API keys from supported AI providers to start chatting.
