Every Feature in ARKA AI for iPhone
From multi-model AI chat to image generation, ARKA AI packs a full AI workspace into your pocket. Here is a detailed look at every feature available on iOS.
Multi-Model AI Chat
ARKA AI gives you access to the world's most capable AI models from a single iPhone app. No need to switch between apps or manage multiple subscriptions — every model is available in one unified chat interface.
- Access GPT-5, Claude Sonnet, Claude Opus, Gemini Pro, Llama, Mistral, DeepSeek and more from one app
- Switch between models mid-conversation to compare answers or leverage different strengths
- Full conversation history with context retention so models understand the full thread
- Rich text formatting in responses including code blocks, lists, tables, and markdown
Whether you need creative writing from Claude, code generation from GPT-5, or multilingual support from Mistral, every model is a tap away.
6 Built-in AI Tools
Purpose-built tools that handle common tasks faster than freeform chat. Select a tool, paste your content, and get results instantly.
Summarize
Condense any text into key points. Paste articles, documents, or meeting notes and get a clear summary in seconds.
Rewrite
Fix grammar, adjust tone, and improve clarity. Transform rough drafts into polished content without losing your voice.
Translate
Context-aware translation that preserves meaning, idiom, and tone across languages — far beyond word-for-word conversion.
Explain
Break down complex topics into simple, digestible explanations. Great for technical concepts, legal jargon, and academic material.
Analyze
Extract insights from text and data. Identify patterns, sentiment, key themes, and actionable takeaways from any content.
Generate
Create content from scratch with guided prompts. Write emails, blog posts, social captions, and more with AI assistance.
Image Generation
Create stunning visuals directly from your iPhone. Describe what you want in plain language and ARKA AI generates high-quality images you can save, share, or iterate on.
- Create images from natural language prompts — describe a scene, concept, or style and get results
- Save generated images directly to your iPhone photo library with one tap
- Iterate and refine with follow-up requests to adjust style, composition, or details
Image generation uses credits, so you only pay for what you create. No separate subscription required.
Conversation Library
Every conversation is saved automatically so you never lose an important exchange. Pick up right where you left off, search for past answers, and keep your AI interactions organized.
- Save every conversation automatically — no manual export or copy-paste needed
- Search and organize past chats to quickly find previous answers and insights
- Resume conversations across sessions with full context preserved
Credits & Pricing
ARKA AI uses a flexible credit system that lets you pay for exactly what you use. Start free, scale up when you need to, or bring your own API keys for maximum savings.
- Free tier to get started — try multi-model chat and tools without spending anything
- Pay-as-you-go credit packs purchased directly in the App Store, no subscription lock-in
- BYOK (Bring Your Own Key) support for maximum savings — connect your own OpenAI, Anthropic, or OpenRouter keys and pay providers directly
Credits are shared across chat, tools, and image generation. You decide how to spend them.
ARKAbrain Intelligent Routing
How ARKAbrain Works
ARKAbrain is the intelligence layer behind every ARKA AI conversation. It analyzes each request you send — considering complexity, task type, and context — then routes it to the optimal AI model automatically. You get the best possible answer without manually picking a model.
Simple tasks like quick questions, grammar checks, or translations route to fast, efficient models so you get instant responses at minimal cost. Complex tasks like deep research, multi-step reasoning, or nuanced creative work route to powerful frontier models that deliver superior results.
The result: optimal output quality at optimal cost, every single time. ARKAbrain removes the guesswork from model selection so you can focus on what matters — getting the answer you need.
